SBF With 900 HP / Is this Possible / HOW

It's been done but there was more than 14psi boost and something bigger up top than some RPM heads. Try some ported Victory Sr's, probally a bigger blower or perferably a turbo and about 30+ psi. The drivetrain is built, built, built, and then go break it and build it again.

Try this, should help alot. Maybe the F1 Procharger may be needed. Where in the heck are you gunna run this in the Bahamas???????????????/

definitely possible. last time i had my car dynoed, i was inline behind a guy from arkansas with a capri RS....thing had a sbf with an F1 procharger. he was there doing a street tune (he was about to do a "true street" event where he had to drive 100 miles between tracks, to 3 different tracks), but on the last pull, the tuner put a lot of fuel into it and he laid down 1247rwhp. don't know if he made it though, lol. i don't remember exactly, but he was pushing somewhere around 26lbs of boost, maybe more. LOUDEST car i've ever stood next to. it was ridiculous. kinda funny because when ryan stomped on it, everyone had to plug their ears, but the old guy in the blue shirt in the first pic just stood there doing his thing, tuning the car like nothing was happening. hahaha.

i plan on doing it, Dart iron eagle 347 backed by a t56v with a f1c at 28psi, should make around 850-900hp

In one of the 5.0 mags a few years ago there was a Bennett built turbo 306 that had an ungodly amount of power. I want to say something like 1700 hp. The guy had a full interior, radio, ac and ran something like 7's as driven on the street! I'll have to see if I can dig up that article.
