overhesting
thanks zip. i will try that method tomorrow. its a summit electric water pump and it worked fine along with all the other cooling parts when i had the 355 smalll block in there and it was not filled.. thats what is throwing me off so much. the other engine ran at about 195 on the hotest day. my radiator is the next thing to check. its a 69 camaro big block radiator and the fan is an electric one with a plastic shroud. i dont know the cfms, but this setup seems to cool down the engine after a run pretty quickly, but it also get real hot again before i get back to my spot in the pits(240). thanks art
