Thread: Performer-EPS

Tweet

I mentioned this on two other threads but got no comments so maybe we can devote a thread to it. I originally bought an Edelbrock Performer-EGR for my mild SBC 350. I am interested in low rpm torque and mileage to some extent with a goal of 20+ mpg using a 700R4 with a 3.55 rear gear. The cam is a very small Crane street cam with 196/204 degrees duration at 0.050" and I believe the lift is a very modest 0.397"/0.410". I will be using 1.5 ratio roller-tipped rockers on the intake and 1.6 roller rockers on the exhaust in trying to get more low rpm torque. Since I expect the '29 roadster with me in it will be about 2500 pounds I should still get some pretty good acceleration with the low gear of the 700R4 and pretty good mileage with the OD 4th gear. So when I had the car in the shop to change over the rear from a 2.79 to a 3.55 the mechanic said he could trade in my Performer-EGR for a non-EGR-Performer at the cost of only installation so I said OK. When I got the car I found he had installed a Performer-RPM which I think is too large a manifold for my conservative cam. So I asked for advice of the tech guy at Edelbrock and he said I should have a Performer-EPS which is the later version (non-EGR) of the Performer. So here is my question: If I keep the Performer-RPM will it bog down at low rpm as in 1800 rpm in OD? And does anyone have experience with the Performer-EPS? The Edelbrock guy says it give a little more torque than the 2101 Performer at low rpm. Comments?
