Has anyone think of? kind of long

[jjw]

combine both M60B40 and M60B44. Will the head, bigger valves and possible upgrade, crank from the 4.0, long stroke, fit on the block of the 4.4, big bore, and the intake, throttle bodies from S62B50, fast engine response, may use the cam,if the angle are the same, from the S62B50, bigger lifts. I know the B40 use duplex chain and B44 use simplex, so the timing cover might be different. The crank jounal size seems to be the same for both, 4.0 and 4.4, so does the bore space. Now the question is the deck height the same? How will the compression ratio be affected? Maybe it will be better just get an alusil M60B40 and bored it up?
What's the going rate for both engine these days? if possible may just et them and see

can you bore am alusil or nikasil???

[jjw]

Alusil can be bored, since it is not just a surface coating like the nikasil did, need to put in a liner if you bored the niksail block.

I think Korman makes cylinder sleeves for nikasil blocks.
