Well Stefano, considering what I've seen recently in regard to prices for some top quality rare cars, the asking price on this seems very reasonable if it is as nice as indicated. Wonder what the mileage is?

[69rsss350]

Better not get those hands too far off the wheel! At 100 mph nothing tracks straight and true on polyglas very long!

[Stefano]

Don,
It is a frame off which was done a while ago and well maintained. The Speedo reads 6X,000 miles (?) and was not reset to Zero. I do not know the actual miles prior to the restoration or how many it was driven after.

For those that have never drove a LS6 with 3.31's..it is a study in mounds of torque, no gear, and small tires.....The car should break traction very easily on the "passing" gear upshift on drive payment at 75mph...literally unreal..

[Stefano]

I have a correction to make I transposed the mileage on the LS6s. The Coupe shows 23,xxx miles and is believed to only have turned over once prior to the restoration.

I was thinking of Rob and COPO Pete when it hit second gear and broke the tires loose at speed under WOT.

Do you guys use a converter looser than stock to allow for more slipage /ubbthreads/images/icons/confused.gif

The torque with the 3.31s will still set you back in the seat.

Kevin said that it ran strong, but then again he drives Hondas /ubbthreads/images/icons/tongue.gif

No, I tend to think you need the tightest converter you can get, to help fight the 4-speeds off on the big end. Mine stalls just under 2500, like the factory. On the skinnies, that's about right. We've tried converters both ways, and the stock hi-po (6 lug) stall speed is about right. Now, if you're running stickies, you can loosen it up a bit. Try raising your shift point...that will help "lessen" the shock to the tires.

[COPO PETE]

Nope. I use nothing but the stock 6 bolt converters in my cars! Stock remember!
Peter

I have the stock 6 bolt converter. However I also found that when we cut the compression back to 10:1 the car felt stronger. I have regular street radials on the car (F70's) and the car will literally lay rubber through 1st and 2nd.

The LS6 has been sold.

Anyone I know???

Yes,it is a board member, but I was told not to say anything or I would get an early X-mas gift. Cement snow boots /ubbthreads/images/icons/shocked.gif

Interesting...I've always felt the L-78/L-72/LS-6 craved compression, and it seems as the compression rises, so does power (the break-over point seems to be 13:1). Case in point: Jensen's Chevelle just ran a [email protected], and he is right at 12:1, in Pure Stock form, and he is considering "Certifying" this car. Our L-72 has 10.2:1, and I wish it had 12.2:1...

[Mr70]

I knew he'd buy it!

[68 COPO II]

COPO PETE....
Where are you finding 6 bolt converters? I had to have my last one custom made.
I was told by GM that only the new Jaguars are using the 6 bolt GM converters....Isn't that a FORD product?

[copo69]

I've got a '69 Biscayne, Black, 335hp 427 auto originally, and raced in Stock class since day one. Original motor is long gone and have been thinking about 427/425 and going pure stock racing or returning it as a stock appearing race car. I'm also interested in 6 bolt converters and if they can be obtained remanufactured. Also pretty hard to check the guts of a converter, any fudging going on? Also, is it permissable to use superceded castings like NHRA &amp; IHRA alow in stock classes? This would be cheaper and also retain the original dated stuff for keepers instead of sacrificing to the drag strip.

[Chevy454]

A note on the converter. I've tried both ways (more and less stall), and the factory converter actually does seem to be about right...on the skinny tires. On stickies it's a different story. I don't know if Pete has done any experimenting with stall speed, but we had trans troubles the past couple of years, so had several opportunities to try different converters. Too tight, and it's lazy out of the hole...too loose, and it simply blows the tires away. So, Petey, is any of this close?

As for the superceded castings, you're supposed to have the right parts per your application (or supposed to anyway). Remember, if you don't certify, the 99% of the tech is done on the honesty policy, unless you are one of the unfortunate ones that gets to pull a valve cover. Some people stretch the rules, others don't.

Whatever you decide, built it for Pure Stock and come play with us!

[COPO PETE]

The last 6 bolt I bought was off this board. They are out there, just look. A few guys on the Chevelle sight seem to have them occationally. I've never touched them internally. Just fill them with synthetic, and go. They are almost indestructable. I've seen them used on big blocks with 250 horse NOS, and they hold up fine. My white copo will just start turning the wheels at 2200 rpm.

Question ... In pure stock must you run smog stuff or is that overlooked. Headers ok or out? Is their a rule book I can buy like NHRA or is it more loose-leaf like some of the other racing I have seen.

[L78Impala]

Hey Rob, are cross over pipes allowed?

Billy

Maybe I should clarify the statement...I am refering to a street driven car, so maybe it has something to do with the gas quality and the ability to keep the car in tune easier. When the motor is freshened (hopefully 2003..) I'll try the "ultimate" performance thing...12:1, headers, stickys in the back, good gear, etc...
