I dont have a desk top dyno, but I would probably say somewhere around 310-320 hp at the flywheel. The heads are what is hurting your power.

Here are a bunch of combos to compare yours to. Most of the stock heads in this set of combonations have been ported a little, so I would subtract around 15-20 hp from what you see here. I think yours should be around 330 hp.

You really need to do somethign about those heads. Either spend a lot of time porting them or get a cleaned up set of vortecs with larger valves.

yea, but if you make your engine more efficent you can go with a shallower differential gear and actaully gain MPG in the long run. Plus pullin up the front wheels is always fun.
