Well I have already ordered them. Thanks for all the info. As far as hp rating, I have headers, soon to be nelson tuned with hot tune 93 octane, soon to be 4.56's , K&N cai , also just purchased servo kits, and will be putting a 2800 stall. That'll be pretty much it. I will be pulling a twenty foot bullet bass boat from here to toledo bend pretty often so the 4.56s shouldn't be a problem. Once the motor goes and my extended warranty ,there is no telling what I will do. Maybe a 6.0 swap with a beefier trans.
