I hear you but it's going to need 12:1 compression and alot of head work to pull it off. The cost of higher octane fuel and getting the heads to flow the numbers to do it will more than likely out weigh the cost of the Crank IMO.
Well, as he said, it's a race car and he also said he didn't care about driveabilty, these 2 factors take your comment of "BUT he'll have to run race gas" and "getting the heads to flow the numbers " out of the argument and make them null and void.
Your "IMO" is just that and doesn't hold water. Porting the heads for either engine will require a lot of work. Pocket porting a head for a stroker is one cost, fully porting a head for a little drag engine is cheaper than getting a stroker crank and pocket porting heads.
While a stroker engine will work less, produce less stress on the engine and a direction I would rather go, this stroker option was not entertained earlier. The OP's thread was on a 318. Are you helping or not? Are you just gonna throw in 2 cents in a direction he did not ask for?
I'm not saying your idea is ill, just not with the program and the comments just become a set of non helping jibber jabber.
