I have a set of 1.7 roller rockers and a B303 cam. Will this work in a 1986 GT. I am using stock heads.
Thanks
Thanks
Thats what I'm worried about. I might just get some 1.6 rockers.If the engine is stock, piston to valve clearance will probably be an issue. The '86 pistons didn't play nice with a lot of cam/rocker combinations.
No that is incorrect. Stock cam is .444 with 1.6 rockers, .472 with 1.7s. B cam is .480 with 1.6 rockers and .510 with 1.7s.Yes you should be fine a b cam only has .444 lift w 1.6 rockers. With 1.7 it will increase only a little. The limit is about .544
The summit help line isn’t going to be checking ptv clearance for you, so I don’t know why they would blindly tell you you’ll be alright.I called Summit Racing and they I'm good to go with the 1.7. I'll give it a shot.
Thanks for the help.

Check ptv before running.
