That... is rather impressive. Be neat to fit that into my truck. I was mistaken, I thought you meant air filter, I do not know how I mixed those up. I suspect the serpentine might hurt me more, as I intend on equipping this truck with air con, and the kit uses a v-belt. Would the flex fan have enough flow for idling? I am recoring the copper radiator, but I'd hate to overheat with a heavy load. I noticed that there are "short" and "long" water pumps, the difference i think is shaft length. Do you know if these are a scam, or an okay swap? How much would HEI improve the truck, versus points and coil? Would an injector system help more than the quadrajet? Is there a way to drill the heads to take a DFI, or is indirect fuel injection the only choice?
