what is the difference between these motors? i see a distinct separation in selling of blocks and parts for those years but i cant find the differences between them anywhere...

does the 94-97 have more hp/tq? or did they change it over to a roller block or what?

thanks guys

 

The only real difference is the 94-97 are roller blocks and the 79-93 aren't.

 

Some say that the roller blocks hit production in 92, but not all the blocks were roller equipped until 94.

If there is a 'F4TE' cast near the casting number, then it is a roller block.

That is the only difference...

I should go back and check on this 351 at the yard in a 92 van again then...
