I cant exactly take my car to the track since its not done but Im curious what this setup would run in a 68 camaro with full stock interior.

396 with approx 450hp
M-21 Muncie
4:10 rear


Is it good for at least high 11s or am I looking at low 12s?

With some good traction and and shifting that thing like Ronnie Sox , you may see 11s , but I'm thinking more like 12s . Just my .02:D

Whats the specs on the 396??
