can anyone tell me the advantage of putting a 351 crank and roller cam in a 302 block,engine was also bored .30 over
thanks for the info,this motor was built in the early 90s by a reputable ford rebuilder,it definitly has a 351 crank in it ,tore the heads off it still has the hach marks on the cylinder wall,so it has very low miles ,also has a set of rebuilt heads with harded seats for 500 bucks ,i think i better grab this,was also rebuilt with all ford parts
More likely they used a 351C crank to do this. You'd have to take too much metal off a Windsor crank to do this. The Windsor mains are something like 3/4" (.750) larger than a 302. The Cleveland mains are closer in diameter to the 302. Cheaper to just use a 3.4 stroker crank now. If you want 352 cubes, just bore the 302 block .060 and use the 3.4 crank.
The early stroker used 351 cranks turned down with 2.3L rods if my memory serves me right. Now it would cost more to machine a 351 crank than a new 3.40" crank. Early in the stroker game you could buy a kit with a 3.5" stroke, but that is just a little too much for an 8.2" block.
whats the casting number on the crank? I suspect you have very very minimal chances of having a 351 crank in a 302 block, especially with "all ford" parts.
for casting number, look on the forwardmost counterweight. 221/260/289 will have "1M". 302 are "2M". 351W is 3M, 3C, or 3M A. 351C cranks are 4M I think. If you see a 3M, proceed to measure deck height to see if its a 289/302 block or 351 block. 302's are 8.2", 351W is 9.2".
