You spell really badly.

Your engine internally sounds good, and exhasut is good, but I think both your carb and cam are letting you down a bit.

For starters, I would be fitting a bigger cam.

How much ignition timing are you running. If you dont know, then how about just telling me the static timing of the dizzy. You might be able to run more, and have the advance occur sooner which will make more torque.

Also, the 2 barrel holley you have, what type of holley is it? How big is it? 4.0 jets, what are these? Is this the diameter of main jets you are running? If so, I think I know why you are not making enough power.

I would be opting for a pair of carbs on the appropriate manifold, maybe a pair of IDF downdraught webers on a manifold.

HP revolves around getting as much air into the cylinder with as little inlet restriction as possible, squezzing it as much as possible, and then getting it out of the cylinder with the least amount of restriction possible.

You have the exhasut and sqeezing side of things covered, but you need to get more air into the cylinder, and consequently reduce the inlet restriciton. A bigger cam and beter indection system (carbs and manifold) will do this.

hey man

to get serious power you need to spend serious money....

how much does the gem have now.... and how much do you want.

it may be worth wile taking a run down to a local TURBO/SUPERCHARGER shop.

i think a twin 22pound turbo would really give you some serious power and the extra speed. or you could get NITRO but from what ive heard it can be costly and pays around woth the motor......
