[QUOTE="americansteel, post: 13787710, member: 149471"] I know this is an old post but I cant help myself I love ford engines :) don't waste your time and money on a 302 with a stroker kit especially with a 347 kit. grab a 351 Windsor, a PR ford can be made with reliability in mind only if you do not exceed a cam lift past 520 and your duration will be dictated by street driving, forced induction like you plan to use and or if you want to race this on the track more than a few times a year. right around 225-236 is nice for a blown or N/A street car. I have come to the conclusion that AFR makes the best heads for any engine next would be trick flow. 185-205 is all you need. a PR engine will not be able to match the reliability of an OHC engine sorry but its not possible and the nice thing with OHC engines is less friction in the valve train and no worries about bending pushrods. even hardened pushrods bend. you can buy a 4.6l port the factory 2v PI heads and put boost on that motor cheaper than a 302 or a 351 based engine. add 1500 for a big bore block which would be the better choice if you want modular power to un shroud those valves. even 4 valve head 4.6l engine's fit inside the bay of a fox body. your gears are fine and I would suggest a build for your transmission. what you want to do with your car will dictate on what components you will buy but the cam shaft or camshafts and heads will be the most you think about. intake manifold? trick flow makes the best period and don't waste your time on a worked carburetor manifold, trick flow makes nice manifolds of course runner length will be considered. since you want boost a forged rotator kit will be needed. you can buy a forged 351 kit for less than a 331 or 347 kit and still make more power with the same heads, cam and amount of boost you use. I haven't built a boosted PR ford in 4 years but I build quite a few modular motors with blowers. I don't need to tell you what blower would be good for a mod motor im sure you know that but a PR ford when I did build a boosted PR I used vortech superchargers. and don't waste your money on a crate engine have it built to suit your particular needs.
