It does have some head issues so i am gonna get the heads completely redone and 2 new timing chains, I have a trick flow Plenum and trick flow 70 mm TB along with a CAI but rather than go all PI i think i will leave it all stock and spend the money on a new paint job :headbang: :headbang: I am still in need of a drivers side electric control switch so i can adjust the seat up so my wife can drive it :laughing5:
Decided to keep my 96 GT stock

you do know that it would be cheaper to find a good set of used pi heads than having yours redone at a shop. you should go the pi route but its your car if you do decide to have your redone at least have some port and polishing work done to them.

It's not slow, I have spent 15 years a a police officer driving around Crown Vics with the police packages in them and my mustang will smoke one of those with the aftermarket plenum and TB and the Tune in it....New timing chains($500) Get stock heads completely redone($250) all new gaskets, Total with labor $1850.00 :violent1: I wish i could do it myself, The labor is killing me but just had back to back lower lumbar surgeries and my Doc would not like me redoing my car...The whole top half of my motor will be new, maybe next year i will get the bottom half done.

Are you sure it's not just a bad fuse on the seat problem? I had the same thing happen on my old GT.

If you are taking those heads off for work at least get a valve job done on them. The stock NPI valves blow and need to be replaced or ground up.
I'd send them to Nick @ MPH for a P&P and Valve Job and pop some PI Cams in there in place of the super junk NPI cams. Add a PI Intake and you will have a very fun reliable everyday cruiser.

I've been hearing good things Nick I might let him do my cylinder heads.DropTopPony said:
I agree though upgrade the garbage non-pi H/C/I it will do wonders in the performance department.
DropTopPony said:
huh? the npi intake valve is far better than pi intake valve.... the pi intake valve is the one that gets machined for more PTV clearance. the npi exhaust valve is smaller altogether, but it doesnt matter with the stock heads because the stock exhaust port doesnt flow....
either way, i agree, send the heads to nick, add some npi bullet cams, and PI intake......

All the flow data I have seen over the years suggests part of the reason PI heads picked up HP/TQ over NPI is the valve job is superior over the NPI even though they are close to being the same valves.
the PI intake valve just has extra material below the seat ring, so there is less PTV clearance than a stock npi intake valve. exhaust valve is bigger, and the port flows better in stock form, so with stock npi exhaust port the bigger pi exhaust valve size is useless. its the ports that make the flow so much better than npi's in stock form.
i've been debating staying NPI when i build my longblock, so i've done alot of research. hardcore npi guys swear they flow as good or better than ported pi's, and some people have flowbench data showing such results, but i've only seen a handful of porters that are capable of getting the npi's up to par, and to get there it cost more than a set of stage 2 PI's. so, i'm still undecided for now.... might just end up going trick flow...

If you want a serious NPI P&P I would get a hold of Jim @ Renegade Racing. Those are the best NPI heads I have seen, not sure how Nick is doing with a race type P&P as of now but Renegades were the best you could get and expensive.
DropTopPony said:
yep, jim is/was the NPI guy years ago, but he charges over $2000 to get the NPIs to flow what a $1200 ported PI does, so it makes more sense to go another direction, especially with the trick flows doing what they do.
stock bottom end max effort i'd go with ported npi's though, to keep compression down for the blower, but my bottom will be built, so i'm pretty much torn between MHS pi's or trick flow 44cc chambers.

its 3v hybrid because of the intake valve location......

I've thought about selling my Fox Lake PI's and picking up some Trick Flow's. Either that or i'm sending them down to MHS for some Time Certs and refresh for another 100k or so of life.
