Thats combo seems to rev good at over 7000!

I spoke to a race engine builder today, might consider an 8.7 deck R Block and do the big over bore and try for a bit over 6 litre, this guy reckons 550bhp on 10.2comp not a problem will spin to 7500rpm..............might last if lay off the loud pedal.

I am not keen on going over 400 cubes so will see what happens, I think this has all been done before and there are many ways to achieve the same results, I wouldnt mind a modular 5.4 but apparently they dont go any better as far as hp but like revving, and the size aint going to fit in my car!
