i am putting some comp cam xe270 cams in a friends car.. we replaced all valve springs.. but when you turn the crank it stops and wont really go anymore... what could be the cause of this? is a piston hitting a valve?? i wouldnt think it would cuz my stage 3 VT cams clear fine... how can i fix this???

Yes it is hitting the piston. Comp cams have an advance in them which is why they hit. You need adjustable cam gears so you can take that advance out or you need to get reliefs cut into the pistons.

is that the only way to get these cams to work on the car???

oxfordgt

Yup they have to be degreed. Sorry. That guy should have done some research before ordering.

racer02GTstang

he did actually... comp told him they should fit with the mods he has...

this sucks.. after replacing all the valve springs, a couple of burn valves... makes me so angry. lol

oxfordgt

Well comp was right they will fit. With some degreeing

racer02GTstang

dang it... i guess today i will put the intake manifold back on and header back on today then.... how do you degree cams btw?? i have never done this before... my VT's didnt need degreeing..
