i run .512 on stock bottom end no issues. i wish i went bigger like .530+ considering on my ptv check i barely touched the clay with 1.94 intake valve.

dont look at alphabet cam, you'll be disappointed.

I run an x303 in my '89 with the stock eec. I'm not disappointed with my alphabet cam. If you're going to be running stock heads I would advise a dual pattern cam though. Still it was a pretty good gain, but I knew I could get better with a dual pattern if I was going to stick with the stock heads.

with a good tune you could probably run pretty much any cam you could possibly want.

ok thanks guys. i thought that sounded wrong. wat cam would you recomend if have world products windsor jr head(58cc combustion chamber), gt-40 upper and lower with half inch or 3/8 spacer(not sure). cold air.70mm TB, i believe its a 90mm mass air,headers full exhaust. i was thinking the F303 or X303. wat do you think. i like choppy cams. and will these cams work with the stock bottom end and with my MAF set up.

screw a letter cam.
from my personal experience and knowing a little bit more than i did when i had the cam and kinda getting a feel for your experience level, stay away from an comp XE series cam.

custom is the only way im ever going again.

I'd say the X between those two. obviously fuel economy will be a little worse with a bigger lift cam. Mine woke the car up quite a bit. It's pretty amazing from around 2500rpm up.

Got any more pics of the car btw?
