Hey guys iam about to wrap up my rebuild/ build up. I got a E303 cam this pass week and wanted to make sure the E303 will work with the 1.7 roller rockers i got. The springs are already upgraded also. And one more question is when i put the E303 cam in do i have to degree it?
it worked fine with my stock set up - 1.7 Crane rollers, e303, stock pistons, stock heads with mild porting, stock length hardened pushrods, etc... I did not degree mine but I would recommend that as well since the motor is out - I wish I had a bit more low end torque but it does fine at 17degrees advanced timing, 3.73 gears, 5spd w/ 3.35 first gear, Performer 5.0 intake, 70mm t/body, 76mm C&L, 19lb injectors, MAC equal length shorties, Taurus 3.8 fan, pullies, AFPR, etc.... I get about 26-27 mpg on the open road with the ability to burn 1st, peel 2nd, chirp 3rd at will....
you can never have too much torque.... =) I love low end pull 0-60 is where I live all day but I rarely drive it hard - part throttle usually - that is why I like the 3.73's
