Re: Valve recommendations for Chevy
Valve shape does effect flow rates especially at low lift numbers along with critical seat angles in the head. To make the right decisions, you must have a flow bench and spend the time necessary on it. Other wise you are just guessing. If you want to compete in Stock Eliminator , you better have a very good set of heads that flow well from the .250-390 lift numbers for your 300hp SBC. 291, 041 etc heads.
Buying Dart or similar aftermarket NHRA approved head will get you out or the box better flow numbers. But you then need to spend the time and money to get the intake runner volumes down to the NHRA CC specification. Steve Teeter STK 620 |

Re: Valve recommendations for Chevy
Steve, I am not aware of anyone that can get the approved head Intake runner volume to the correct CC. Can you fill me in on who is able to do that.

Re: Valve recommendations for Chevy
There are a couple of Dart sets out there on Brian Tilburg motors that are very fast on F and G cars.
Brian is in PA. Steve Teeter Stk 620. |
