i am looking for a few opinions on a camshaft for my car. the car is an 88 hatchback mustang and weight with all iron engine and driver is around 3200. i want the baddest cam that i can get away with stock springs and converter and compression. everything else will be upgraded though here are the specs on my engine. i want a lopey idle but i still wanna drive it alot.
78 460
weiand stealth high rise dual plane intake
stock heads home ported and gasket matched
stock short block
8.5:1 compression (guess for stock?)
hooker super comp headers (2" prim. 3 1/2" coll)
3" exhaust
stock c-6 trans (planning on upgrading converter later on when money permits)
800 cfm edelbrock
the two cams that i am looking at are but noit limited too:
lift int, exh: 569-569
dur @ .5 int, exh: 234-244
and
lift int, exh: 512-538
dur @ .5 int, exh: 214-224
what do you guys think? too radical? any info or suggestions would be greatly appreciated.

I think you can get away with the smaller of the two cams, although I'd definitely upgrade the springs. The stock springs for that were definitely very lo-po, the ramp on that cam is pretty aggressive and would put you in valve float with those springs. I think it will be ok with the converter and current compression.

I wish you luck. I have the same cam in a big two door and it is a gutless turd below 3000 rpm. However, in a light car with good gears and open exhaust(all of which it sounds like you will have)it might run like a streak. Just my $.02. It all depends on your setup and rpm range. Choose your cam wisely.

well i dont remember if it was a lunatti or not how much does your car weigh??
my car should weigh 3200lbs with driver at the most
it will defieneyly have an open exhasut
and for gears it will be no lower than 3.08 and no higher than 3.73s, the car has a 7.5" rear in it right now and i am not sure but it may have 3.55s in it right now.

Intensity is shown via the difference between advertised duration and that measured at .050 valve lift. The smaller the number the more aggressive the cam lobe. This is why the comp cams extreme grinds are said to produce more power in low compression engines. They open the valve sooner and quicker, thus helping low rpm efficiency and power. If I am way off here, maybe somebody else can line you out. I have just recently started to understand the importance of cam selection. Read all you can and get the best understanding possible of the dynamics before you shell out the bucks for a cam you think looks good.
