Was at a coffee run this morning talking with a buddy who is building a strong Y block and his engine builder says he is going to try and fit a (I think) 400 chev crank into the Y block?? Kinda like polluting an old ford putting in a chev crank though. Anyone have any info on this and what it achieves . Though he had a Y block crank they tried to straighten ,now he has two short ones!!
I had read somewhere that you can modify a 292 Y block crank to put in a 289 Ford....from what I can remember was a less expensive forged crank than a K code or something like that.
hey, if Kaase can build one with chevy heads... The y-block crank in 289 thing was commonly used to do a steel offset ground stroker back in the sixties. I think they used to do a deal around 318 inches??
Perhaps it's the forged chev crank that's an advantage. There were some forged y block ones but I think they are not too common.
I was trying an Allison in my 427 years ago , all worked great just couldn't find a short enough connecting rod . Damn the luck , I was hoping to have a big cube on the cheap [emoji12]!
Kaase welded up a set of Mummert heads, and used a Chevy manifold. IIRC, he used 40 lbs of rod to do that. If a Chevy crank would work, he would have done that too. Made good numbers, I think it was for sale for $17K when the EMC was over. I woulda bought it, but I wouldn't have enough left to cut a hole in the hood. LOL.
Old thread but the engine we are talking about has been built and is sitting ***embled in the guys shop waiting to go in the car. He has a y block in the car currently that he is having to much fun with. He is planning on putting in the chev crank motor soon.
Not really a whole lot to say. I don't know the exact details but the guy we are talking about who is a mate of mine was having a hot Y block built. The shop stroking the y-block cranks kept snapping them. So they went looking in the Manuals to see what would fit and don't quote me on this but I believe the crank they found that fit was a 400 chev crank.
Ok .i will try to get hold of the guy and gets some pics , if he has any. Its going in a 29 Willys whippet which already has a y block in it. No it doesn't resemble a 29 Willys any more in case you were wondering.
OK maybe he said a 400 FORD crank it has the same bore space as a Y block at 4.38 .......... Now a small block chev has a bore space of 4.4. Maybe he just said 400 crank and common thought was GM not FOMOCO.
