Help with U/SA

[Jim Wahl]

I was pitted right across from Billy at G-ville and only talked to him a couple of times during the whole weekend. I wish I could have sat down with you Billy and chewed the fat for a while! Billy has forgotten more than the average guy knows! next time Billy, next time. Jim

P.S. I hope Don is feeling better! Get well soon Don! We love you! Jim

I would def. go with the Metric with 5.38s and the 92.5 ro 30x9 radials. You can run those tires over 40psi. Will put you around 6500-6600 from 100-102 through the traps. Keep it cheap as possible and see where it lands. Maybe better than you thought. I was curious on the carb though. Can it be a dual jet or is it the computer carb.

It's a U/SA car! You're looking at 91-92 mph in the lights.

It doesn't have to be a feedback carb. You just need a 1.21 venturi dual jet. Basically ,it's the front half of an 800 Q jet.
You guys DO know ,you're going to have to put a custom 12 bolt in that car, in order to be able to play with the gears?
I'd figure out a baseline on the ratio, and then ,when you go lower and don't pick up 60' but lose MPH, go back to where you were!
BTW, if you're not too deep into that car, I'd back right out of it ,and into a 78 Camaro 305 2 GC 2bbl car .
You could use the 8.5 rear that comes in them.

Thanks to everyone for replies on U/sa. Will probably ask for more help as we get further along with this thing.

If you're looking to build a "dime rocket" then I would absolutely agree with Mark. There's no cheap way to put a rear in a Monte Carlo that will give you any gear selections. I think that both combos have about the same overall potential.
The only other thing to consider (other than having a car vs. finding and buying a car) would be the difference in weight between the two. The Monte Carlo has to weigh only 3170 to make U/SA while the Camaro has to weigh 3770. I like towing light cars.

Valid point, Billy.
I actually didn't realize the hp rating on the 267 was that low.
It might be worth a shot for someone willing to spend the money on the rear end.

Maybe some math major could analyze the specs and give us a hp and torque potential.?

Keep it coming guys, I love the modern low class tech lessons. Must be from my old P/S junior stock days & old age.

It wouldn't be too expensive if he could find a GN rear!

I would not put 1 cent into that combo but I have a brand new set of .060 cast pistons in the box for FREE. It's the carb! The 305 2G is a possible and by the way I have one for sale HAHA just needs the motor. I have not had much luck with any two barrel.
