I have an 87 GT with flowmaster mufflers, off road BBK H-pipe, BBK shorty headers, and a cold air intake that I made. I am looking to get more high end power out of my engine. When I'm cruising at 60 or so it just doesn't seem to pick up like I want it to. So I decided to get some GT40 heads, re-hone the cyclinders, and a new cam.

My question is what cam should I get with the GT40 heads and the above setup to produce more power at higher speeds without knocking down my low end power?

I was also considering going to a 331 stroker. About how much would it cost to get the cylinders bored out? Will this stroker kit work well? eBay Motors: BUDGET 5.0 302 331 347 FLAT TOP STROKER KIT MUSTANG TMD (item 200246377516 end time Jan-09-09 22:10:26 PST)
which package in that listing do I want? What size over bore? I also plan on adding a turbo within the next year or so, would this be a problem?

well is your car converted to mass air, if not your gonna have to be careful on the cam selection, im in the process now of converting Im doing heads and cam in the spring, also if your gonna turbo you will deff need to convert.

I would go with the ford e-303 cam it makes good all around power and works good with gt40 heads.

Yeah I was leaning towards the E-303. I'm gonna have to go to mass air pretty soon. How do you wire in the MAF sensor though? I know you need an A9L computer and the new wiring harness, but how exactly does the harness fit into your existing system?

It'd be best to get a kit rather than cobble one together, then you'll get instructions on how to install it all.
Just know there's always a trade off... if you want top end then you will sacrifice some on the bottom end.
