| RE: Opinions wanted for street 390 |
| By Mike McQuesten - 12/16/2001 2:53:01 PM; IP 63.50.124.245 |
Again, I agree totally with Travis on the torque convertor issue. I've run a B & M 2,500 stall and a TCI 2,500 stall on the street. Both were designed and designated as Street & Strip with marketing names....like street fighter or Saturday nigh Special or whatever crock name they wanted to call them. But just like Travis I didn't like them on the street. Just too mushy. Nice off the line starts with street tires though. But a stock 390 convertor or a 428 CJ convertor feels a whole lot better.
A comparison of a Perfomer to a Perf. RPM would be very interesting. But you have to take into consideration the cam used too. Edelbrock is right up front about the intended use of the two intakes. The Performer series is just that - a nice step up from stock for street performance and recreational pulling power. The RPM series is a major step up. Street use is fine but you probably intend to do get some strip action in.
One more thing Jim, if you do build a 390, use a 600 CFM carb. It's all you should need. If you do build a 428, then use something in the 700-750 CFM range. And just one more thing....have your machinist build you an engine with a head/piston combination that yields something in the 9.5:1 range. Just makes more sense for powering the hefty bird around. |
