Th350 , weight of car to be determined yet, its a 80 malibu, lightend up somewhat, I would have to guess 3400 or so ? I dont have a stall yet, but i'm figuring around 3000-3500, All i have right now is my shortblock 357 stock lower end fairly fresh, flattop pistons, I should be right around 10.5 to 1 comp, right now, And i have a fresh set of dart iron eagle 180 runners, milled to 60cc. I dont have a cam yet, I also have dual plane intake, and no carb. So thats why i'm trying to figure which is the best way to go. I'm not looking to get real crazy with the money. If i got a kit from scat or eagle it would be one of the lower entry level 800 or 900 dollar kits ! Just didnt what kind of gains i would have !!
