overheating
one thing, now that you mention it is that that in place of a thermostat there should be a restrictor plate. there is none. there was one when i had the 355 in there and it just never made it back in with the engine swap.. it is a drag car only, 13-1 comp and big cam and big alum cylinder heard. what about me only having a 7lb pressure cap. some say it should be up in the 20s lb cap.its a small electric fan running off a relay and it did fine for the 5355(max 200 temp at the track) i have different restrictor. plates. how big of a center should should be on the plate. why the lines from water pump to the heads and not to holes in top(center) of block. why not run all 3 different cooling lines at once. thanks art
