many guys seem mesmerized by the need to post 600-hp-700-hp peak numbers from a 496, BBC,
and while 600 hp plus numbers are not hard to reach if you build the engine for max power,
with the correct cam, compression, heads , intake ,etc.
the problem with that is, the engine built to produce that impressive peak power will almost always ,
be a p.i.t.a. to drive on anything approaching a longer trip.
because the cam duration required mandate,the engine run exceptionally well in the 5000-6500 rpm range, and the need for the cars drive train too be geared too match the engines power range, the combo youve built will be more street driver friendly and may be more fun to drive on the street.
you can reasonably assume you've lost about 18% in drive line power loses,
so your engine is more than likely making about 18% more power than the dyno shows.
I'd also point out that as you learn to tweak/tune the combo youll be able to squeeze a bit better,
power.
keep in mind a 3.31:1 rear gear should allow you to get semi reasonable fuel economy, for an engine that size ,
if you drive that manual trans and keep the rpms generally under 3000 rpm,
something you would be unlikely to do with a properly set up 600 hp plus engine.
and yes I'm fairly sure theres some rather easy extra power available if you make minimal changes,
but get comfortable driving the car and do your research before making more changes.
