There's a cheaper fix than this. Buy a Katech belt tensioner and your problem will be solved. I had the same issue with my built 403ci engine and we are pretty close power wise. Put the new tensioner on and never throw another belt again.. This is where I bought mine from.. I know of to many people that has had issues with an electric water pump on a street car. If it's a all out race car then you are o.k. but if I were you I would want to leave the mechanical pump in favor of the electric pump and it's not like you will make more hp going to the electric pump. It might take a 1/2 hp to turn it. Just my .02

If your car weighs as much a mine does (3540lbs race weight) You should be a low 10 second high 9 second car with that motor. I went 10.39@129mph right off the trailer. Once the motor lossens up some and I get my rear anti sway put on I should be able to lower my 60ft into the 1.36-1.38 from 1.41 and shave some off the big end. I'm hoping for 10.0x's or 10.1x's at the track next time out.. I

I'm not a fan of the rectangular heads. They probalay would have make around the same power with the right cam. The rectangular heads seems to flow more but the cathedrals seen to get down the track faster. I've always ran TFS heads but decieded to go with Mast this time.

3000lb Curb weight is about 300lbs lighter than my curb weight. What all did you take out of your car? I want to keep my car streetable but would love to shave a few extra pounds. My cars raceweight is 3540lbs and I am 210lbs. Hell if I could knock another 300lbs out of my car I could probably get into the high 9's on motor.. Got any pointers?
