Tech Question
Matthew Reimers, Hamburg, MN, 1978 Aspen Super Coupe 360
Out of the factory, the Super Coupe's E58 360 only put out 175 HP, obviously they had to try hard to make it that much of a slob to only crank out 175! What is a good way to let it out out much, with it still being a practical car? Is there ways I can hop it up easily and inexpensively?
Matt, it responds well to the usual hopups!
The heads suck, but, still, 225 or a bit more (net) HP is pretty easy:
- headers or early 340 exhuast manifolds and decent dual exhaust (at least 2.25", gonna need to be side exits in front of the wheels)
- Early 340 cam and springs (If you got "hotter" than this you'll want steeper axle gears and a higher-stall torque converter)
- Minor porting & cleanup / backcut intake valves / plug and smooth out air injection "humps" etc
- Slight head mill (not over 0.020")
- Lean Burn in garbage - MP ign. setup
- Tear out air cleaner silencer baffle
- Carb (with minor rejet and rework for vac advance use) and intake (with egr blockoff) are fine!
You should probably consdier a mild shift kit in the 727, mainly to raise upshift RPM. The rest of the drivtrain will be fine.
