GM crate engine L31-R, factory cam.
Summit stage 1 intake.
MSD 85551 Pro-Billet distributor(over kill but it works)
Holley 770 Street Avenger carb(over kill but I had a new one sitting here)
Long tube headers, 2 1/2 inch exhaust, Thrust welded mufflers.
TCI Street fighter th350 trans, factory stall converter
3.07 Gears in the rear.
255/70/15 tires all around.
This set up has a lot of low end torque and will cruise the highway with no problem. I fool a lot of people at the traffic lights and if riding along you floor it, it will pull you back in the seat.
The best part is I rode around this morning for 2 1/2 hours and burned less than 5 gallons of gas. I was just cruising slow but my old motor would have burned way over double that.
I didn't check mileage but I'll bet it was at least 20 miles to the gallon.I believe the secret is in running the factory cam and factory torque converter. At 45 to 50 mph the motor sounds like it's almost idling.
I would recommend this or similar set up to anyone looking for a new motor and trans.
