so whats the difference in GT40 and GT40P heads? :dunno:
and now i see a GT40X or something...but at $600 EACH...i dont see those in my future....the GT40's seem to be about the only head ill find used and not cost a fortune. :yes:
also since we already talking about me being poor....is there a decent "budget block" that can handle 400+ rwhp? without breaking like stock 5.0......obviously i dont have 2k to put into a block. :balls1:

A properly tuned 5.0L will handle mid 400 RWHP. Keep it under 6,500 rpm and maintain a *conservative* A/F ratio. Thousands have done it with success.

Got that right. Good luck finding one for a reasonable price!! Everybody and their mother knows about this swap and the prices went through the roof!!!!!!!!! Almost as much as a trick flow or edlebrock. The heads I have seen go for as much $450- 500. Couple more dollars and you have a set of RPM's.

I've got a set of heads, and an intake if anyone is interested. I also have 351w heads. I would like to trade them if at all possible. Ive got my tube chassis fairlane that needs alot of parts to be finished.

B-cam or f-cam would work fine, if you go with exploer heads the ones with the 3 bars on the head can be used with mustang headers, the later ones you need special headers. I have a explorer gt40 intake if interested I may sell.

I just paid 200 for a set of clean GT40p w/o rockers and rods. I also paid 200 for an Explorer upper and lower intake. On top of that I need a 65 or 70 mm throddle body and maybe an EGR spacer. How does that compare to an after market setup?

95-early97 heads are GT40s
later 97 and up are GT40P heads
the intake is similar to the GT40 intake but is setup to make more lowend then your typical GT40. the lowers are the same
you can use BBK shorty unequal lenght headers on the P heads.
when i cared about my other stang i had this same topend on it
