I was planning on using the Edelbrock dual plane intake with an operating range of 1500rpm-6500rpm can't remember the Summit code # does this help with a HP estimate

I have a 1989 T-5 with the 3.35 first gear and a 3.70 in the differential. First gear is almost useless, unless you plan on using your car to pull floats in a parade. I have what I think is a "box-stock" 1989 5.0 HO engine from a Mustang GT and I can idle away from a dead stop in 2nd, 3rd, and 4th. I seldom use first, most of the time I only use 2nd, 3rd, and 4th in town. My .675 OD (5th gear) is useless for anything other than highway cruising, but b/c my engine isn't tuned for high RPM use (yet) I can comfortably cruise at 70 MPH at less than 2,000 RPM's and get close to 25 MPG (YEAH....gotta love that!!!). With your cam, you'd not want to do that, it would "lug" the engine and kill your gas mileage (not to mention that the rich fuel mixture at those low RPMs might well wash the
oil off your cyllinder walls, and you certainly don't want to invite early ring wear).
Bottom line, I'm glad you're listening to Brent! You won't be sorry.
Cheers from Dugly
