most NA hp out of 3 valve?
#16
the highest someone has told me they have gotten with heads/cams full bolt on's, lightweight driveshaft, full exhaust with o/r x pipe was 383 rwhp. There may be someone with higher than that... but thats the highest i have "heard".
#17
Highest #'s 387 on a Mustang Dyno, said they runs 6-9& lower than others so you can do that math. That's the stroker almost to a 302 (301 1/4) 9 1/4:1 compression, ported & polished heads full bolt ons and a 17 pound Fidanza aluminum driveshaft along w/aluminum flywheel & pressure plate

So again, with spending how much money and what done basically, are we talking about to take a stock mustang GT coupe to 305-315rwhp? Then what to take it to the next level of 320-340rwhp range?
Then can you go higher than that reasonably with the stock block and engine assuming you've done all the bolt on with cams and heads. Or is that the limit without machining the engine and internals and all the other expensive options?
Everyone or anyone, what are the limits with the engine as it is with better cams and heads with all bolt ons, and the total price roughly?? Thank you, Erik

I don't honestly think you can get 320 at the rear, I'd be happy to see some dyno sheets prove me wrong though. And it's not really the expensive options it comes down to a safety issue with a lot of the parts, its just choices you have to make. Like the driveshaft, clutch assembly & internals, if you go f/i like I will some day, it's a peace of mind that your not gunna puke a piston through your hood

Heres a video from Sutton they have this one at 350rwhp lists the mods and the dyno sheet. Should be able to get to 350 without the FRPP heads but there are a few other mods that they dont have listed that one could add to gain some additional HP. Plus everything depends on how extreme you go with the mods. I am sure someone could get 450hp+ out of a NA 3v engine with enough money and some very extreme mods but is it worth it. Most I have seen was 420rwhp in a mag article and as I remember this was stroked not sure on exact displacement with heads.
