Should I port my stock intake?
OK Gang here is the deal:
77 TA with AC, 455 with 4.25 Eagle crank, SRP +.035 Pistons, Eagle 6.80 rods. Heads done by SD Performance back in 2006. Flow sheet shows 245 at 600 lift. Cam is the old UD 231/239 around 500 lift on a 112. 1 3/4 Hedman headers, 2.5 duals with H pipe. Aftermarket ST-10 with the deep first gear with 3:23's out back. Q-Jet atop of a bone stock Edelbrock Performer.
After reading Rocky Rotella's articles about how the performer sits 1/4 lower in the back, therby dropping the shaker and how Cliff Ruggles states the E-Performer is a restriction I'm going back to the stock 77 intake.
My question is, is it worth having SD port it ? For 400 bucks and 3 horspower I wont do it. Is there more to be had with modifying it ??? Thanks in advance !!!
