Need input with 408ci Setup Ok well I been on a long vacation.
I currently have a 408 short block built from what use to be Combination Motor Sports. This short block has been sitting in my room for about 2 1/2 years, maybe longer. It has a Callies 4 inch crank, Oliver billet rods and custom JE pistons. I had them build it for a huge shot of nitrous ( 250+ ). I also have a brand new rossler TH400 with a T-brake and 3800 stall converter. I gutted the car completely. This will be a drag race car only. I just logged on here and there are alot of new products i dont know much about. My biggest concern is cylinder heads. I cant seem to figure out what kind of heads I'm going to need for my application. After figuring out what heads I'm going to be running I can start buying piece by piece on the engine.
