i did a search and nothing came up. i would like to know your setup and how much horsepower it makes with race and pump gas.

 

Some Dyno charts from "Just Garbage" http://www.jgenginedynamics.com/dynotests5

 

here i am. This year im going for 450 with a new block

 

will that be with or without headwork. do you think 400+ hp can be attained without headwork but an upgraded valvetrain?

 

I think it can be done without headwork but it will require alot more boost. I have had my head done twice. The first time i got a JG Pro Series head and then it was sent out to Portflow a few months later do have it done right. I also use Crower 62404 cams and Ferrea 1mm over valves. In my opinion the key to a fast Ls is head work. The stock .380 lift cams wont get you far and ignore Crower with their cam classifications. So far everything up to and including 404s made more power in my car.

 

I'm looking to get 350 whp on 91 octane gas and a stock head on 21 psi
