i see alot of talk about the 7age hybrid and how sometimes it can be a bitch to do. would putting the crank from a 7afe into a 4age block be possible?
ext: small block 400 crank in a 350 block strokes it out to 376cuin
ok just finished looking at both engine specs. i now see that the two heads are not the only differents, the block has some differents also. as said before the 4age has a crank size of 77mm and the 7afe has a crank size of 85.5mm. looking at the 4age engine with will require grinding on the block with a maximum stroke approaching 81~ 82mm. max. also the deck height on the 4age is 191mm and the 7age deck height is 206mm.
yea i understand the concept, i was just wondering if anybody had put a 7afe crank in a 4age block. but then i read that the most stroke you can have on a 4age block is 83mm. then by reading more about this i notice that the 5age engine is just that a stroke/bored out 4age engine. so thats what i might build this summer/fall.
