stock vs. aftermarket intake
Guys, need your advice if it is worth spending money or not on an intake.
A friend is selling his stock GM 1980s BBC cast iron intake off a 454 truck pretty cheap. Should I get the Performer instead (off ebay, for ex.)?
Here is the engine: 69 El Camino, 454 engine, 750 cfm Q-Jet, stock oval port heads, stock springs, Crane Max cam duration: In: 204, Exh.: 216, Lift. In: .484, Exh. .515, LC: 110 (rpm range 1500-4500), 3.08 rear end, power brakes, 2000rpm converter and somewhat beefed up TH350.
Will I lose a lot torque/hp by putting the stock intake for this almost stock engine combo?
