Max horsepower with EQ heads?

RAMM said
I'm a skeptical person by nature and have kicked many a "salesman" off my property. This used to horrify my wife and kids but I have taught them over the years that nothing is free and you have to ask yourself "What are they getting out of this?" Sorry a little off topic but I feel this sentiment is shared by IQ and myself.

I don't see the high side of 600HP happening with EQ's and a "portjob". We all know that achieving 80-85% of total potential is relatively easy. So lets say 500-525hp 408 with EQ's is easy that would represent 80-85% POT. Now ramp that up to 90% and you are sitting @ 550 hp IMO. Ramp again to 95% and youre tickling 600hp. Ask any serious race engine builder what it takes going after that last 5%----MEGA time/money and the real kick in the balls is that you may never get there. In fact IME going after that last 5% you often go backwards and make LESS power only to learn a bunch and get tired of that kicked in the balls feeling.

Having said that---I am as curious as a cat and would love to see you try. I'm about to embark on a personal challenge of building a 600HP NA 318. I view my goal easier to attain than yours-and that's a major hint right there. 4" stroke is not the way IMO. J.Rob

I would love to try, but budget and the fact that i have a just freshened bb (with some very expensive updates) to race says not in the cards. But i am curious what you think my pile of leftovers would do for power . In my first post i mentioned them; vacuum pump, hat injection on a Tunnelram running methanol, and lets just say Santa would put the valvetrain under the tree Brian used on the 606 hp build. Looking at the domes needed to get 13+ compression makes me think going higher compression might not be a good move, so say 13.5/1. Or possibly 14/1 as the chosen ratio. RAMM, when you mentioned 600 hp were you considering the vacuum pump and TR with methanol?
And on that last 5 percent; i have a sore butt from trying to make my 528 go faster. We do indeed go backwards a lot once we get close to 100 percent. In my case I flat ran out of racing budget.
