3.750 stroke & 6" rod take a 1.125 CH, sounds like you have a 3.48 stroke 6' rod 350 piston( 1.740+6.000+1.250=8.990)

Thank B36, these pistons were on ebay and I think the person posting them has their facts a bit messed up from what I could find anyways. He claimed they were for a 383?

Thanks for the fast response!!

Sjakes, are you looking for some .060 pistons? I have a set of trw's, .220 pop ups for a 350 for sale.

Bill, no I'm not, I was just trying to figure out if those were for a 383 or the spec numbers were incorrect.

Thanks although

Just to correct your deck specs....

(1.875 would be half the stroke, plus 6.00 rod, plus 1.250 CH, equals 9.125) so, either the stoke in the orignal post is wrong or the CH is wrong......I think that is what sjakes was asking... OR YOU NEED A TALL DECK BLOCK.....

1.25 ch is for a 3.5 stroke 6 in rod motor.

No corrections needed, didn't figure the 3.75 stroke,showed th 3.48 stroke numbers, he already had a pretty good Idea the 3.75 stroke was incorrect. Also a 1.125 Ch would take a 6.125 rod on a 3.50 stroke
