Well, you could strip down your motor yourself and buy a 331 stroker kit from somewhere and have the block work done, installed, etc. I would honestly just find it alot easier to buy a shortblock/longblock/crate engine from someone and call it a day (yes, its a 5.4).

And yes a KB blowzilla would fit onto a 302, 331, 347; its all the same block. But for some reason I believe the only lower manifold you can use with a KB is GT-40??? (someone correct me on this if I am wrong).

I could not give you a prince on a crate motor; there are just way to many different factors. Heads/Intake/Pan/Ignition/Internals/Forged/BlaBlaBla... A couple good companies to check out are DSS/Coast High Performance (CHP)/ Ford Performance Solutions (FPS)/Keith Craft/etc. Go on any one of their websites and they should have cratemotors for sale. And 99.9 percent of any of these companies will built you a custom motor if you dont like what their crate motors consist of... just remember that.

Trill Gear Head

thats what i meant, i meant a crate motor. either already built or just the shortblock and i'll get some AFR 165 or 185 to put on it.

I found something i like http://www.coasthigh.com/Assemblies/Ford/ford_331.htm which is the 331 street fighter pro shortblock. What i want to know is what is the difference b/w shortblock and a longblock? and if i get a shortblock(i think its just the engine block with pistons etc... what would i need to buy serpeartly, i know i will need heads, Intake manifold. What about a oil pan anything else? and what level difficulty would you rate putting a 331 in?

so does the 351 have its own version of the gt40?

Topless1995GT

Well I have a 351 in my possession as we speak, as to what type it is i am not sure, I have an old beat up 1995 F-250 with a 351 in it sitting in my drive way collecting dust. The motor has 235k on it as it sits but runs like a champ. Anyone familiar with the 95 F-250 and that model of the 351 I'd like to get your input.
