I am running the 4l60e with a fuddle 3200 converter. There is a guy about 45mins away ( genIII performance) that is going to come down when I get it ready to crank it ( hopefully in a week). Yes I am running the ls1 flat tops with the 5.3/4.8 heads that have had a heavy porting and polishing job done to them. I am using a stock ls1 intake until I get the funds for a ls6 intake. The cam is a patriot performance, 226/226 and 585/585 you can buy them new for about $275 and I picked up mine from the guy that is doing my tunning for $150 used out of a customers zo6 vette. I bought a set of mac mid lengths for a f-body and the look like they are going to work without any major surgery. I am going to put 2.5" exhaust with a h-pipe and some resonators for the exhaust. I also bought a set of patriot gold springs that are good to .650 lift and they come with retainers, locks, valve seals, and seats for $225, they are the best deal out there. I also ported my oil pump to boost up the flow a little and upgraded to arp bolts where I could afford them. Also you can save some serious doe if you do your own harness, it is not hard. One more thing, I am using the stock tank behind the seat. I took the sending unit out and drilled a hole and installed a piece of 3/8" tubing for the pick up, I went to advance and looked through there pickup socks for a efi fuel pump and made it fit on the end of the new pickup tube.
