I have a 91' GT and I am thinking about building a stroker motor for it. I have gotten some advice from my local speed shop, but wanted to see what some of you have done. I'm looking to see what heads and cam specs will be optimum. Which injectors and mass air? Are you running stock electronics? I am new to the 5 liter world. I have been a chevy guy my whole life but have always wanted one of these fox body mustangs and finally I have one. I am looking to end up with between 400-450 HP on premium unleaded. I don't want to have to run racing fuel or additives.

Waht size stoker are you looking at doing and what is you intended use?

347 don't look back, tfs "fast as cast heads" custom cam from CI...as for intake, victor jr efi wouldn't be a bad choice if you want a short runner intake. 1 3/4 headers into some 3 inch exhaust, 30 lbs inj match the TB to intake opening as for mass air...80-90 mm unit and any other supporting mods like a good ignition, but in the end expect a healthy investment in all this that'll easily hit your goal......others will chime in with variations of this set up or even improve upon it

Budget comes to mind after that post.

what price/budget are we talking, what does a good setup run total $=

mjr46

that's a broad question^^^^^^^^^if your starting from scratch on a stroker build, anywhere from 4500-6500 pending on quality of parts used

wow thats the answer i was looking for but not wanting to hear

STROKER SHORT BLOCK runs 1900.00 from the right place
heads 1200.00 to 1500.00
cam...300.00
efi intake 400.00 to 600.00
gaskets, valvetrain hardware and all fluids ect ect, it all adds up quick, but these are all figuring you're buying new, you could lower cost on some stuff shopping smart

I was going to do a 347, but trying to keep it around $4500
