Finch Posted October 13, 2012 Report Posted October 13, 2012 or a stock stroke 68 bore cub which is a 392 Quote
Colby Posted October 13, 2012 Report Posted October 13, 2012 the "cub" cylinders are 68mm in bore size.. the difference in size of motors are.... stock stroke 68mm - 392 4mil stroke 68mm - 421 7 mil stroke 68mm - 443 10mil stroke 68mm - 465 pretty much a ton of combinations, depends on the power your wanting, what your wanting to spend Quote

"most" cubs are 68. however you can get them in any size from 64 to 68.... For example I just sold a 66 bore cyld. Quote

Finch Posted October 14, 2012 Report Posted October 14, 2012 gg yes, but you have have to get the cylinders ported for the difference in 4 mil port timing you sure? different deck height. i love my 392 Quote
BANSHEE HP Posted October 15, 2012 Report Posted October 15, 2012 gg yes, but you have have to get the cylinders ported for the difference in 4 mil port timing no, the port heights on a stock stroke cub to a 4mm will be raised too high.... now if you spent a bunch of $ to get the cylinder welded up, reported and plated, along with some custom domes, different pistons and base gaskets you could run it but that would be the ass backwards way of going at it.
