"well it probably wont be a 4 valve head but something of the sort..."
Hmmm.... a 3-valve head????
I give up... My imagination is limited.... obviously.
IMHO, the limiting factor on power production with a /6 motor is NOT the size of the motor, but rather, the breathing ability of that cylinder head that has breathing commensurate with a 170 cubic inch motor.
And, there is not much that I am aware of in terms of a head that woud flow sufficient numbers for 250 cubic inches, much less 300.
But, what do I know? You've built a lot more of these motors than I have...:notworth: And that's the truth!!!
