GT40 heads i have friedn who has them

[mrltd]

well i aculy was wrong on the year it was either from 87-90 foxbody stang ho or a 94-95 and guys how much do you think i can get out of all of this new came and heads, I m looking for 300hp and little more than 300 ftlbs of torque

Well, it'll take a bit of money to get 300hp...but you will get within 50hp or better with a decent cam, intake and the GT40 heads

[mrltd]

Well, that depends on your state? Do you have emissions tests?

[83countrysquire]

You might want to read up on the laws and see what you can get away with.

I know my laws pretty well and know that I can only get away with so much.

You need to get the part numbers off the heads.

Best way too get power is porting the heads and stilll meet emisions. Use a mild cam with low over lap.

well i ll have to check my friend says there g40 how can i tell

If the heads are on the motor, look at the ends. They will have 3 lines if they are GT-40 and 4 lines if they are GT-40P heads. just below the end exhaust ports will be cast GT if they are GT-40 heads and GTP if they are GT-40P heads.

how can i tell the year of a motor

Once you know the decade it was made in by all of the misc. casting numbers on the motor, the easiest way is to just look on the intake manifold or under the valve cover on the head and you will see the casting date.
