Do any of you guys think i got a chance at the 400+rwhp club I would like to know if any of u can give me any close #'s??check my signature below

 

NO! Not unless you are running a huge solid roller cam and 13:1 compression ratio. The guys making 400rwhp+ NA have fully ported heads and decent sized hydraulic roller cams. Your heads have only been polished on the exhaust, basically stock.

383 + stock heads + hotcam = around 340rwhp.

 

If you want 400 at the rear, you're going to need better heads, and depending on your compression, maybe a bigger cam.
