BBC Tarantula manifold vs weiand tunnel ram ?

[Resurrected69ss]

Hey guys, I'm building a mostly period correct 69 camaro. I'm going to be running a 427 .60 over (439) 12:5:1 big block with heavily ported 990 heads and a bullet cam. I have a mint edelbrock tm2r tarantula manifold and also have a weiand pro ram, I'm in love with both the super stock and pro stock theme but what will make more power ultimately? Tunnel ram with 660's or that tarantula with a good carb? Thanks guys!

Thanks,
Vinnie

The TR should make more power.

If you're going to drive this on the street, be advised that 660's do not make good street carbs in stock form. They're mega rich on the idle circuits and do now have power valves so they're mega rich at part throttle cruise as well. Due to their throttle linkage design, they bring the secondaries in very quickly as well.

Thanks man, yeah I've heard that a few times before. I'm definitely going to go through them and update them so they can be driven on the street.

The 660s are center squirters also. There is 1 nozzle in the middle. Boy I think I would opt for a pair of nice 600s or maybe even a pair of 750s with mechanical secondaries, 6109s.

I agree when going for Tunnel Ram on the street, but since this is a 12.5:1 motor I feel there is a lot unknowns to make much of a recommendation. Motor specs, E.T. goals and intended use?

660s are race carbs -- not even intended for street right along with the TR. If you're hell bent on the TR suggest a pair of 600s. As far as drivablity -- the Tarantula with maybe an 800 or 850 DP would be more liveable ... TAZ

[Resurrected69ss]

Motor is a 427 Bored to a 439ci, heads are 990 rectangular ports that were completely opened up by brandywine many years ago, cam is a bullet solid roller still waiting in intake to order it. Its going to be a fun street/ strip car. Depending on time probably not to much strip haha but want the power for when I need it. I'm sure I can get this car into the mid 10's with 4.56's. I've built a few race cars but nothing this old school.

I agree. But I have a few old timer friends that have used them on the street and never had an issue. They fixed the lean idle problems somehow.

Sounds like a fun project. With all due respect, why 12.5:1 compression if you are going for more street? We recently made 500hp with 9.3:1 and modest fuelie heads on a little 302. Mixing race gas on the street sucks.

I think you can easily meet your goals with the Tunnel Ram.

Honestly Paul I got all the engine parts for practically nothing lol. The forged crank, rods and pistons were all under $500 and the crank and rods are new. I already had the 60 over block. I don't mind running race gas for the simple fact of I'm not going out on long cruises maybe an occasional 20 minute cruise to the local shows or the occasional weekend romp. All my engines I built were always pumo gas on the street. If this was an everyday or constant driver than by all means i wouldn't even think of running anything over 10:5:1

[Plowman]

BBC Tunnel Ram with two 660's sound's cool and you only plan to drive it an occasional 20 minute cruise,YES COOL. I think you would drive it more if you like it too.

Plowman I'm going to end up driving it every chance I get once I lay into it lol...

[dboles]

A pair of 450's would be better for the street with a TR. A tarancula manifold has no low end torgue. Maybe with a big block you could make it work for the street. On a small block they are just terrible. That's why the torker manifolds came out so soon after the complaints they got about the taranculas.

[Plowman]

So you are thinking of going anything over 10:5:1 cruise. Mixing gas is a pain.

[EZ Nova]

We recently did 14+-1 for the street. I have found that there is no &quot;golden rule&quot; for pump gas. That's just my finding.

I too like the &quot;OLDe SCHOOL&quot; or &quot;PERIOD CORRECT&quot; style stuff. It's alot harder to do with old, cheap out-dated stuff then the current stuff.

You haven&quot;t said what it's going in?? FYI I did a 396 (402)/375Hp L-78 OEM bottom end (11.5-1 TRW std bore), but added ARM bolts, 840 heads, Comp 660 roller cam, 1.73 roller off Ford Cleveland, Strip dom intake and Holley 800. 1969 Nova M-21 and 4.56 12 bolt. Heads were home-ported and car went 10.47 FIRST and only FULL 1/4 mile hit. This was in about 1996/97 time. So you should be EASY to hit your goal if Brandywine did the 990's. I think your going to be 9's if your using the TR.

I'm putting together 4 motors like this. The above mentioned L-78 396, 427-390Hp, ZL-1 and ZLX. I have 3 tunnelrams and 9 intakes. ZLX is going to be set-up with at LEAST 12.5-1 comp and a Eddy TR2-X tunnelram, just not sure if it will be 4150 or 4500 carbs as I have one of each.

Good luck, should be fun! my L-78 style 10.40 motor was when it was streeted. Shifting just over 8200 yippy!

[VintageMusclecar]

Just out of curiosity, what did the `69 Nova weigh?

It's going in a 69 camaro, that's why I asked about your grump lump! Hahaha. Yeah I think it should hit low 10's with out a problem. As for the race gas I've built a few race gas &quot;street&quot; cars and other than the price of the race gas I really don't mind. EZ NOVA your set ups sound badass! Any pics??

[PxTx]

Scott and Ken just tok that Yellow Deuce to 10.7 I think with a little 350, I trust you can run your number. Can't wait to see pics.

This car went 10.70's?

No, that car is just started the transplant / freshen up.

THIS ONE WENT 10.75

So EZ Nova you are putting together 4 engines for the street and for 4 cars.

NO, ZL-1 is going in the '69 Nova. Going to be set up for F.A.S.T. style racing and another series up here in Canada that MUST run a dual-plane intake. The ZLX will be the &quot;back-up&quot; to this ZL-1 and will most likely be more street then the ZL-1. Also looking for another car for one of these over the winter/next spring.

The 427/390Hp motor WAS in the '69 Nova. went 10.40's as well. This was the 427 &quot;Polished Sneakers&quot; motor that Pat Budd built years ago and since it's just sitting in parts, might as well put it back together. Same with the old L-78 &quot;spec&quot; motor. Short has been together since it ran 10.47, but did sell off the top end. BUT since I have aquired the ringht '69 840 heads and matching '69 &quot;163&quot; intake, or a few other &quot;Day 2&quot; intakes. These motors might see some time in either my '67 Acadian that is going back on the street, or my '61 409 Pontiac if there is an issue with the '09. Also looking at a nice '57 that has a junk 454 in it, so one of those 2 could be a nice addition.

So these 4 motors, &quot;COULD&quot; see any of the 3 current cars, or the 2 that I would like to acquire. I think the ZL-1 SHOULD be in a '69 Camaro and not my Nova. And I just like a &quot;driver&quot; '57 Shoebox.

ok, so IF MORE POWER is what your after, use the Pro Ram. With these old intakes, the TR starts really coming on about 4500 RPM and will ALWAYS make more power by about 6000 RPM and keep making more. IF you DO NOT have carbs, get with a good carb guy and let them lead you in the direction you need to be for the best of both worlds.

&quot;jmarkaudio&quot; over on YB.com would be a good one to talk too, but any good brand name can do it, we personally use Dale Cubic at CFM. But go TR and don't look back.

I was even looking at these for the street:

Never had a weight on my car. Just a normal, all steel full weight with steel headed 396, M21, 12 bolt bench seat and rallys. What 3300 lbs or so.

EZ NOVA sell me that grump lump! LOL! :-)

Vinnie,
I've had the Tarantula on my Booth-Aron L72 with an L88 attitude since I bought it in '84. After having some cylinder head massaging and porting, it it a killer on the car with 13.5:1. I run the new Holley 850 with 4 idle circuits. I've never had it stop pulling, even at 6800 w/88 gears and a T400.

YES it would still be &quot;pulling&quot;! That BBc with those spec and gearing will &quot;pull&quot;. BUT I think his question was/is &quot;would it pull HARDER&quot; with the tunnelram.

Little food-for-thought from BIG Joe Sherman:
&quot;To the O P --- Know this, a tunnel ram is only better than a good single four barrel ABOVE 6000 RPM--- below that , the single four will be better-- You are all mixed up with your thinking
