Head and cam choices for 95 Lightning??

I am considering using a Lightning shortblock in my Mustang and had a couple of questions.

What are the limitations on cylinder head and cam choices for the stock Lightning short block?

I am worried about piston-to-valve clearance issues and ned to know limitations on valve sizing, cam lift and duration figures, etc.

I need to have a pretty exact yay or nay on this cuz I can't clay it up....I don't have the short block yet. I am gonna order one if I can run the combo I want to.

Thanks guys.

I'm running AFR 185's with a Crower 15512 cam with 1.7 rockers. You have plenty of clearance space with the 15cc dish pistons in those blocks.

So running something with a 2.02 intake and a cam with no more than about .510-.520 lift should generate some pretty good numbers and not have any clearance issues? Got it!! Thanks for the help guys....guess I am goin 351!

I'm running AFR 185 heads too with .530 lift on intake and still have plenty of room for more lift as long as you don't run huge amounts of duration.

Too small. Get something with a minimum of a .540 lift and duration in atleast in the upper 220's to 230's. Custom cam would be great. I'm thinking about it. I think the TFS 2 or 3 cam would be nice. (don't remember which)

I don't think so. 15cc is a deep dish on the piston. My cam is a .544 lift and a 228 duration (highest points on lift and duration) and I have no problems. Make sure you check the National Lightning Owners Club website.

Well if numbers mean anything my cam is 211 @ .050 and .530 lift / 222 @ .050 and .520 lift and the peak torque was at 3300 but that was before I upgraded to a edelbrock rpm intake and 75mm throttle body instead of the gt-40 and 65mm. I still have a restriction with exhaust which I need to get figured out but I know that before the intake swap I had 286hp and 363tq at the wheels but I hadn't even began tuning with the tweecer yet.
