Ok here we go, i have a 1991 ford pickup , that had a bunt up engine that was a previous a auto zone rebuild, .060 . 010 crank( Junk) . So that engine was out of the picture for an over haul candidate. Now i was in quest for a new, used worn out or whatever complete 302 ford efi engine. and i found one, sitting out front of a guys shop. great i thought, so i went in and asked the guy behind the counter if it was for sale, and he said it was junk , "water in the oil, the engine is shot" i told him i didn't care, i want it. Taking a risk that i wasn't worried about, i gave the guy 125 bucks for the complete engine minus the distributor and one manifold, didn't matter anyway, i had that on my old first engine. Here is my question, after getting it home, and tearing it down hot tanked everything and took the engine block to the machine shop, i was reviewing some pictures that i had taken from the tear down process and found the block casting numbers EOAE , D3C and 3J30 , from my understanding of the numbers, that makes it an engine from 1983 " carb" with somebody swapping the EFI and everything form a newer one , like my 91. So, moving on i find out the heads are D8OE ,69cc , that's like ,7.99 to 1 ratio, ech, that sucks even more, i had a set of E7TE's on the 91 stock .


So, here are my questions, do the E80E heads suck for a stock rebuild? If I buy an engine kit off on Northern Auto parts for a 1983 302 , and put the fuel injection back on, will it be right? , or would the engine perform under its capability due to the fact that the kit is for a 302 with a carb. ? What should i do?

 

The only real difference between the '83 block and the '91 block is that the '91 was actually a roller block. It didn't have a roller cam installed in it, but it was designed to. Both engines use the same crank and rods, but the pistons are different. I'd probably ditch it for a roller block, but if I had to keep it, I'd get an '83 rebuild kit w/o pistons, and get a set of pistons for a '91, and use the E7TE's.

However, here's the possible problem; I don't know for sure if you can use the E7TE's on a non-roller block. You may experience problems with the pushrod length and geometry.
