Did carburated and efi have different covers? I need to know if a 87-93 timing cover will fit an earlier 80s carburated engine. Thanks
Well, that's odd .... the FRPP page (Ford Racing Performance Parts [M-6059-D351**])Stock covers are differant. Newer EFI engins have a serpentine belt, and that reverses th4 direction of the water pump. The water passages in the front cover were changed to accomadate that.
I have a '68 GT350 with a '69 351W. The car has new everything (radiator, heater core, t-stat, water pump with drivers side inlet) but still runs hot.The water pump backing plate has round holes in it, they're not shaped like the ones in the timing cover, so the water pump doesn't care what timing cover it's bolted to.
As an example, I'm running a timing cover from a 1970 351W (standard rotation water pump) on a 1987 block, with a reverse rotation water pump bolted to it.
The only thing that matters on timing covers is whether or not the fuel pump and crank sensor mounts are there if you need them. If it has the dipstick hole and you don't need that, just run a pipe thread tap into it and put a plug in.
