Good luck on your backup "Bullet"
More head would be a head that flows more. :shock:
If you're not even going to make 700hp with a 632, why not just run it on pump gas? Just curious. I'm sure I'm not the only one wondering that.
Lessee, What the initial question concerned was "Were Bear to buy a 632 BBC, what compression ratio would be a good one for high altitude racing?"
Answer, 14 to 15 . . Then I asked for more particulars concerning the same issue.
I never said we had or were using a 632, nor did I bring up any HP facts . . I did note that "More Head(s)" weren't an answer because there's no such thing. What you do (or might do) to a head might be a factual answer, but more head is just a pornographic request . . While it might be a good idea, it won't make you go any faster . . In the second post, I did mention an estimated HP figure(s) from the current engine we are racing, but never connected that to any 632 statements, nor did I give the CI . . Thus, any answer to that specifically, would have been less than a partial answer (had one been given) because you didn't have enough facts to build on . .
Apparently my critic is better at jumping to conclusions than giving specific and factual advice or answers . .
As I said, I've done this before, but not with the engines, tuning or modifications that a BBC responds to or likes . . I don't have all the answers but apparently enough to understand that specific heads and the way you use them require more than grabbing a roto rooter and making them "Bigger" . . Flow is very dependent upon the combustion chamber size, RPM range you intend to operate in and Valve sizes, duration etc . . Thus, "More head" is like saying "More Gear" or More Driver" . . Exactly "How much More" becomes the question . . and specifics becomes the answer . . :roll:
And thanks, CNC for your specific answers . . . They're appreciated.
