Its funny...I read of a naturally aspirated 292 6 cylinder drag engine that put out 650 hp...that's not bad at all...So...all depends on what you want I suppose...I'm a die hard 6 cylinder guy and all because there's plenty of resources for parts and they are far more unique imop. And I just like to encourage people to do something like this if they're considering because there are to many discouragers out there.....its becoming a chevy vs ford thing. LOL!  |
I think it's neat to see them in stuff, but I personally just don't really see them as being a great N/A power platform. Like I said before, I think I'd have to go with forced induction if I was building one as a hot rod piece.
The lift is certainly not the only thing to consider about the cam...what are the other specs?
BTW, what N/A 650HP 292 are you referring to? Cotton Perry's car made 549HP in the article I read (and also seemed to be pretty hard on itself).

For a comparison, the Hot Rod guys later made 567HP with the same 454 on 91 octane (and 614HP on 114) with a solid flat-tappet cam.

I guess part of it is also the application; your SWB stepside half-ton only weighs something like 3,500LBS and my truck weighs over 1,000LBS more than that at around 4,600LBS. To make matters worse, mine is also going to use a wide ratio truck trans and be asked to pull heavy trailers.
