i am dropping in a carbed 350/th350 combo i bought , it ran 13.2 consistent in a full interior 79 monte carlo with 3.73s. i have a 90rs GUTTED, nothing but a dash and a seat. what kinda times will it run with 3.73s and that much of a weight reduction.

12s

Yeah probably high 12's if it ran that in a monty. What are the specs on the motor?

sounds like a nice combo for 12s, ur going to need to hook up though any suspension mods?

12.9's or 12.8's is my guess, assuming the RS hooks like the Monte did.

the motor is std bore 350 with a 292 cam, p&p 60cc heads, comp roller rockers, lifters, pushrods, pink rods, kb pistons, carter comp 850 with a dinosaur scorpion intake.
