Reply to "ENGINE BUILD REVISED - COMMENTS WELCOME"

DJEZC,

I disagree with the 6.2 rod on the 9.2 block, that only leaves 1.00" for the ring package, & part of that is of course the big side notch in the piston for the Cleveland's intake valve relief. I don't understand what can he be thinking? The 6.00" rod leaves 1.20" for the ring pack, which is marginal, especially for a Cleveland. As far as stroke to rod length ratios go, the 1.5 ratio of the 6.00" rod is adequate for a hard running street motor. How far into the rev range this motor will rev with a 6.00" rod I can't say, the stroker motor scene came along after I stopped building hot rod motors. Dan Jones was planning on a 6.00" rod in his 4.00" stroker, I used his name intentionally hoping by using his name he'll pick up on this post & comment. Scat is building 4.00" kits for the Cleveland using a 6.00" rod. You could place a call to Bob at Scat and speak to him about the 6.2" rod & ring package, the man sells stroker cranks for a living & knows his business.

Outside of my comments about the rod length I do not like being put in the place of commenting on another mechanics work.

Problem with bearings with good "embedability" is they don't stand up to abuse, the babbit peels off them like ribbons. You'll find it in your oil pan during the first tear down, honestly & literally. I've seen it many times. You want the tough bearings. You'll avoid scoring your journals by changing the oil regularly & running a good filter.

you're welconme to e-mail me at gp_fillmore@yahoo.com. If you'd like to discuss looking out for what's best for you outside a public forum.

your friend on the DTBB, George
