so question guys ive been doing some reading and ive read that you can get about the same amount of hp gain with a pi cam swap, a head shave for the compression, and the pi head. anyone heard about this? ive been reading its about the same but its cheaper cause you dont have to buy the heads. input? thanks

I believe that is accurate, though you are adding cost for extra machining (ports won't line up perfectly without some machine work).

Get a quote on any of the work you cannot do yourself, then compare the two methods.

Used PI heads are not very expensive, btw.

Thanks. The cheapest set of heads I can find around here are 350 minus the cams. There's some on ebay but shipping is ridiculous and I would end up paying more.

Interesting! The gains are pretty well spread between the intake, cams, and heads, so I have no problem believing that you can get similar hp without swapping the heads themselves. Be aware, though, that the compression gain is a relatively small portion of the total hp gain of the swap (~8hp?) If you find out that you can skip the head shaving and cut your budget in half, it would be worth considering. Depending on the cost, you might find that you could get more hp/$ by doing the intake and cams and then some bolt-ons.

Good luck with the component shopping... it took me a few months to find a cheap set of heads, and I think I got really lucky (150 for the set, fully assembled).

i have a lot of the bolt ons already on my motor. Diable ecu. underdrive. k&n short ram. throttle body. plenum. exaust. looking for a h or x pipe with hi flo cats. yea that is very cheap. the ones i found are 350 minus the cams and he said need slight work i beleive i posted the craigslist ad up here a little while ago. they still there. local head shop has cams 100 and an intake i cant find none around here on craigslist havent called any junk yards yet but to have one shipped its about 200 is what ive found for a new one. so 650 so far for just those parts. a lot more then you guys paid. so im still going to look around. any idea about how much a port and polish runs?

I have no idea what a regular P&P job runs... mine was done by a coworker that used to do it professionally. He WAY uncharged ($100 for 16 hours of work). I've heard of others paying close to a grand.

I think $350 for cam-less heads sounds reasonable. Not a smoking deal, of course, but if you're ready to move forward with the project and just need the parts, I'd just go for it. Personally, I'd go for the new heads over the shaving of the NPI, but that's probably just a matter of preference. Cost is likely to be the determining factor (isn't it always? )

Thumbs up

i did the full 2004 into my 98 swap i think it is easier then just doing heads and intake and depeneds on where you get your motor form could also be around the same price if not cheaper.
i got my motor form autogator complete just needed power streering pump, ac pump, and crank pully. for 1046.00 just use my ac and power streerung pump and crank pully. but not that the exausht header is a bit diff for the 96-98 form 99-2004 just have to use a diff size nut to bolt it on

Degreeing the cams is recommended. Though the design helps get them close, there is still a good bit of slop left.

Hey I don't know if anyone can help me out or not, but is it possible to use a computer from a 99-04 GT in a 96 with the complete PI swap (block, heads, intake, etc. is new) for the performance gains? It still has coil packs so I'm not sure if it will work or not. If anyone knows please give me a shout

I am thinking about the swap, do you have to give your ecu a tune when you do this or not? I have a 1997 GT

Hi Mustangandy that's what I am working on right now. I have a pinout for the 96-97 I need the pinout on the 2001. I have a 2000 GT pinout I don't know if it is the same I think so. So what I want to do is repin the ECU and add some wires for the COP's. The speedo sensor is different also.
