Stockish  HO 5.0??? If so and the Camero is running anywhere as it should, plan on getting your ass whipped...

Many different levels of the 350.  Many different rear end combos back then too...  My buddy has a 350 auto with 2.43's out baack.  Runs perfect, but slow.

The 350 is not the original motor, RS never came with a 350 for the 68 model year. My brother ran the numbers for my uncle while they were doing work and it turns out to be a 175hp~ish corvette sourced 350.

I know he won't get his one-wheel-peel off the line in front of the Cat with 265s and a locker.

265's are alot of tire for only 220 at the crank, figure 190 at the wheels just for the sake of using numbers and rough guesses. i would begin to worry about trying to get all that tire rotating, alot more rotating mass then 245's. there is too much of a good thing sometimes, you know?

I COMPLETELY agree with you.
...but, the tires are in great condition with alot of life left. I could not beat the deal for 2 wheeles/tires for $40. I wanted an extra set of wheels for something stickier on down the road, but these were a plus.

I think that would point more in the department of torque.

Now that I think of it, I just might do a test on times/traction with air filled Vs. Nitrogen filled.:hick:
Then I will test prepped Vs. non-prepped street tires more then I already have.

I LOVE the last sentence in that article, it's what I always tell people who skimp on tires:D

Yeah in the 70s, but no '68 ever had 2.43s... Maybe 2.91(or similar), but I'm figuring a R/S had at least 3.23s

And no 3.50??? Probably more R/Ss had 350s than any other engine...

It's a '69.  The build sheet says 2.43's.  Original owner was 24 years old at date of purchase from dealership in Nassau County New York.  Sorry, I should have specified it was a '69.
