its the stock disributor . i bought better spark plugs and wires from autozone and put them in last yr . i was thinking of edelbrock 2101 intake manifold as my last mod not sure if that would be enough hp though . im guessing im around 250hp now my goal was 300 hp .

Re: Horsepower Help

im tellin you man, you would be surprised by how much a good set of rocker arms can open up an engine. especially if you have a decent camshaft

in addition, an upgrade to that q-jet and stock ignition would probably help you achieve the numbers your going for.

Re: Horsepower Help

hp is tough to estimate with a parts list alone, especially with stock fuel delivery and ignition.
