a lot of the guys on this forum ARE engine builders, professional engine builders who do "max effort, budget is no concern" builds...so don't be so quick to dismiss them and take the word of your local guy as gospel.


who IS your local guy anyway? what are his credentials?



No offense, but you seem to contradict yourself... you say that this is an all out, money is no concern, max hp build...then state that you're only after a mild 500-550 hp.

Box stock edelbrock heads are nearly good enough to get you there for $1500. spend another $500 on porting, and you've got a set of heads that will EASILY make 600 hp., why spend all the time and money worrying about maximum size valves on exotic heads when your hp goals aren't all that high?


are you using an R3 type block? or a stock production block?
