Got a motor for my Blazer - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My brother pulled the motor out of his 99 silverado which I am getting cheap. It is a 4.8 and has a 4l80e. I am going to put a 5.3 crank in it and have it bored out and run LS1 pistons and rods in it. So bascially be a iron block LS1. I will get a set of LS6 heads and intake to go on it also. Should be around 350hp or so. What you guys think??

Get yourself a nice 230ish dur cam to go along with the ls6 intake/heads and you'll be making 400+rwhp with a good tune & free flowing exhaust. I'm heavily into the ls1 scene & have tuned a couple h/c ls1's.....lemme know if ya want help with parts selection or tuning questions.

I hope to get my crank, rods, and pistons in the next week or 2 and I will start tearing down the motor. I need to put my camera in my truck and take some pics of the process. I hope it turns out to be a good performer and get some decent gas mileage. We drove my brothers 69 camaro to the Super Chevy @ Huntsville last weekend and got over 20mpg with it, it has a ls1 and 6 speed.
