It can be done both ways...depending on your needs and pocketbook.

its the crank that causes for a long stroke.

 

ext: a small block 350 has a 3.480" stroke and the smallblock 400 has a 3.750

the 7afe has a 85.5mm stroke and i guess the 4age engine has the same size stroke as the 4afe engine which is 77mm.

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.

 

 

thanks again

You could probably buy a 4AGE engine already built and swap it into your car.
