Fast Class Racing

[DZ Fool]

Could someone descibe the different classes and rules in this type racing.
It seems to be mostly a big block dominated class

Thanks Danny

[John Brown]

It's sorta easy. Start with a 55-74 North American assembly line produced car or Ranchero, El Camino etc. Car must "appear" stock. Almost anything goes (except nitrous) if you can stuff it into a factory available block that looks like one that was available in the vehicle you are using, must use original casting # heads, intake manifold, and a correct or correct appearing carb. Oh yeah, gotta have a stock body, paint and interior and no lightweight or fiberglass panels that would not have been assembly line installed. Blow it out through ported or extrudhoned original exhaust manifolds and a 2 1/2" mandrel bent exhaust system. Largest tires allowed are one # larger than came on the car, or G70's if the car came with a smaller size.

That's most of it, but check here (http://forum.yearone.com/forum_posts.asp?TID=39&PN=1) for more complete information.

You talking about racing on the skinny, Polyglass type tires? If so, then there are basically 2 classes:

1: Pure Stock (http://www.geocities.com/psmcdr/rules.html) - must retain stock engine specs, stock suspension, etc.
2: Stock Appearing (http://www.fastraces.org/rules2005.htm) - must use factory correct engine pieces but any internal mods are fair game, some limited other mods.

The racing that Rob, Copo Pete, JJ,Casey Marks, Dave H and myself are running in is the Pure Stock (factory stock) racing. It ranges in times from JJ's L88 (I believe it was 11.74 at last September's race) to 16 second cars. Of the people mentioned above, I am one of the slow cars. My car (4200# race weight on radials and 3.23 gears) went 13.57 @ 102 last September. It has to be one of the funnest things to do while still having clothes on! http://www.yenko.net/ubbthreads/images/graemlins/naughty.gif

Other than purely for fun if I would brong my 302 Z to one of these events be like bringing a knife to a gun fight

[Chevy454]

Not at all...as Rusty said, the cars will represent the entire spectrum, from the few of us hardcore tuners who are looking for every last .001 of a second, to those guys who just enjoy stretching their legs every once in a while. If you've never been to one, there is simply no good way to describe it...except it's a BLAST, and highly addictive.

I tell ya, you should try and make the Martin event in June, as it's just up the road into Michigan from you...not too far, and you'll be guaranteed a good time!

[SmallHurst]

Besides, there are several small block screamers out on the track. One of the great things are the shootouts! You are matched up with the closest qualifier by time. Most of these shootout partners are within .1 of a second. Best 2 of 3 headsup racing! I had better slow down, my heart is starting to flutter! http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif

Anybody got a pic of the Crazy Cajun and his LT1 'vette? That thing flat hauls http://www.yenko.net/ubbthreads/images/graemlins/shocked.gif

[70Z]

Do they run these events at certain tracks only or what?

Sounds fun!!!

[YENKO DEUCE REGISTRY]

The main event is in Sept. at the Mid Michigan Motorplex in Stanton, MI. There is another event there in June, I think it was taken over from the Factory Stock event that used to be in OH. There are other events that are starting up around the country, but it takes a few years for these events to grow.

One of the best events is at an SCR http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif I don't know of anywhere else where you can count on racing 3-5 other Yenko Deuces http://www.yenko.net/ubbthreads/images/graemlins/shocked.gif

[SmallHurst]

So Marlin, are we going to see you at Stanton in Sept.? If nothing else, I don't mind whipping up on you at SCR9! http://www.yenko.net/ubbthreads/images/graemlins/haha.gif

[YENKO DEUCE REGISTRY]

Sure, bring your deuce - leave your 455 at home http://www.yenko.net/ubbthreads/images/graemlins/grin.gif

[SmallHurst]

Come on Marlin, you mean to tell me that your scared of a land barge motor pulling 4200# on 3.23 gears! (Oops, I forgot you we driving a little bowtie http://www.yenko.net/ubbthreads/images/graemlins/blush.gif!)

[YENKO DEUCE REGISTRY]

No, but I did see where you claim to be slow with a 13.57'ish - do you remember my et's from last year http://www.yenko.net/ubbthreads/images/graemlins/naughty.gif

Thanks Marlin. Unfortunately I don't own a Yenko Duece or even a Supercar for that matter, but it sounds like a fun time.

Tom, I've only been to the last two, but I dont think I'll miss another one. These are cars you'll NEVER be able to see elsewhere.

You got till September, make plans now. Like the old US 30 commercials used to say..... BE THERE!!

[Belair62]

70Z...you don't need a Deuce or a Supercar....hell we have seen rental cars make a pass !!

[DZ Fool]

Can I run Headers on my 302

[Chevy454]

Not at a Pure Stock or Stock Appearing event, DZ...look up towards the top of this thread at my earlier post, and click on the red Pure Stock link...that will bring up the rules page.

Are you talking about the FAST Class or the SCR? SCR is an invitation thing I thought. http://www.yenko.net/ubbthreads/images/graemlins/hmmm.gif

[Xplantdad]

AT SCR...you can race whatever you want to...just pay the entry fee and race. I might have to race the rental this year! http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif

[Jim Ferron]

Does anyone have any first hand knowledge of what these guys do to Rat motors to get them to run low 10's high 11's? I can only guess...anybody know?

[L88 CORVETTE]

Jim
You asked how we make the Rats run?Well,More cubes to start with,most guys are over 500,mines 511.Then its roller cams,rewoked intakes,raised exh ports,extrude hone exh manifolds,reworked carb,mandrel exh system,hi compression,some over 15 to 1. Lots of dyno time and a pile of parts in the corner of my garage that was supposed to the "magic bullet" and didnt work!It's a full time job staying ahead of the Hemi's and Buick's!!!!

[Jim Ferron]

WOW! To anyone not familiar with FAST racing, Wayne Nelson is the F.A.S.T class record holder at 10:59-130 MPH!

I guess I couldn't get a better guy to answer my question! I'm honored!

I watched you guys at Musclepalooza II with great interest. If you are running 511 cubes that must mean you have 454 + .060 + 3/8'' stroker correct? [That's what I guessed] And if you are running gennie [074] L-88 style heads, doesn't the increased spring pressure create havoc with the exhaust stud bosses?

I am building either a 496 or 511 [NOT for FAST class]myself but with the use of vintage heads [14011077 Rect OC raised ext port 'C'] personally I worried about the ability of being able to fill up a 511 with juuust a flat tappet cam and I was worried about the reportedly bad castings holding up to the increased spring pressure [your opinion?]

One more question...with all the torque and no tire to speak of when, during the 1/4 mile pass can you actually go to WOT without worry of tire spin. I would think tire spin could happen even in high gear let alone second ...no? Do you think the Corvette chassis offers an advantage to traction that other Chevrolet cars don't?

BTW...Congrats on the record !

Jim: Maybe try a Rev Kit...

[L88 CORVETTE]

Jim
The bore is larger,.125 over,and the stroke is shorter,4.25.My heads(074) have welded in reinforcment for the stud boss problem you speak of,the rev kits are too tall to fit under stock valve covers as far as I know. As far as traction goes,I have been lucky,almost no wheelspen off the line,about 10 or 15 feet in 2nd gear,none in 3rd!

[Chevy454]

Wayne: a Rev Kit sits in the lifter valley of your block...shouldn't effect valve cover fit at all.

[L88 CORVETTE]

Rob
Sorry,I was thinking of the stud girdle that goes under the valve cover!Oops!I thought Jim was referring to the head problems the 074's have with breaking off rocker stud boss' with hi valve spring pressure.Maybe your Rev kit does the same thing,only in a different way?

[Jim Ferron]

1/8 overbore? I didn't know that was possible??? It makes sense though as 4.375 stroke would seem to be soooo torquey [word?] that it would never hook up. Do you have to sleeve a block to get to .125 over?
Wow.. that would the best of both worlds.. 511 cu in with only 4.25 stroke.That's a big dog!

And just to remind everybody, 4.250 stroke is the standard stroke of a Pontiac or Olds 455 and I believe the Buick 455 was behind @ 4.312 So stroking a 454 chevy [4.00'']1/4+ [.250]ONLY brings it to BOP's standard stroke....

I do remember a 70 LT1 Vette I used to own always hooked verry hard but that was with...about half the horsepower [360 / 700 ?] am I close Wayne?

BTW I don't believe the 'Rev Kits' you guys refer to address the weakness of the exhaust bosses vs. GIANT spring pressure of a modern roller cam.

[Chevy454]

The Rev Kits help by upping the pressure on the lifter, but only on the lifter [body] itself...the extra springs take part of the load off the valve springs &amp; other related peripherals. Ask your local stock car racer...he'll know all about 'em...

[L88 CORVETTE]

Jim
No sleeves,block is not filled either.Chev Big Blocks have mucho material to work with!I've been tossing the idea around of a F.A.S.T Ford Fairlane with the FE 427,but the cylinder walls are very thin and really limit the whole large cube idea.We'll see what happens. http://www.yenko.net/ubbthreads/images/graemlins/naughty.gif[ QUOTE ]

I guess you didn' t see the my personal best run from last fall. I managed a 13.28 @ 102.49 last November at KCIR. http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif

We'll have to get you a deuce to slow you down http://www.yenko.net/ubbthreads/images/graemlins/grin.gif

[Jim Ferron]

On the Rev kits that are in the lifter galley, Two purposes...1. If you break a rocker arm or push rod, the RK will keep the lifter in place, not allowing the cam to throw it out of the lifter bore[also preventing a wide open oil pressure loss] and ...
2. It ends the slamming effect [which breaks stuff] of the cam throwing the lifter off the cam's ramp at higher RPM, really any RPM, which is limited to the valve lash.
The springs have very low tension and don't allow you to lessen in any way the seat pressure [250# maybe] of a roller cam.

[retengw31]

Wayne/Rob:

Would the Olds DRCE block interchange with the Chev big block? You could use Oliver tractor pistons in that (well, almost). I recall the Olds "W30 boys" were assigned that after they lost their own engine to play with. They took the basic BBC design and beefed it in the critical areas. Pro Mods run them (Keith Elkins, others) Anyway to make one of them look like an L88? I think the top ends from an L88 will work. Isn't that about what the Mopars are doing with the repro Hemi Blocks?
