since it is so cold here, and there is no chance of taking the car for a ride in the next 3 months, I was just thinking,

Given the following parameters, which engine would you choose for the most reliable performance in the 550+hp range:
Must run on 92 - 93 octane pump gas - high priority
Must be street drivable from 2,000 to 3,500 rpm
Redline rpm around 6,000
Fit in an ERA 427SC

This will most likely become a BB/SB debate, and that's not my goal. I was looking for a little more on specifics as to the best way of getting a drivable 550+hp engine that won't blow itself up, and run on pump gas.

If it turns out to be as simple as tweaking a 428, then the next step is to find someone good that can tweak the one I already have. BUT I am keeping an open mind to the fact that a quicker revving, newer technology SB may be more reliable and a better option.

Sorry for opening this can of worms again.
