Cam Question?
 

I have an 87 GT with SD. I read somewhere you could change the as long as you did not go over .220 @ .50 this sound as if the E cam would work. Has anyone tried it or have any suggestions.
My car has already got shorty headers, h-pipe, underdrive pulleys, fenderwell cold air kit, 3.55 gear, smog pump remove, and weld wheels.

The E303 camshaft will work. Good luck! Light em up!

Heads and intake come before a cam.

The SD cars can accept camshafts, and the E303 has been used by members on this site with success. So has the B303. Making it work will require an adjustable fuel pressure regulator.
