    Default 89 c6000 small block to big block engine swap

    I'm re-posting this question on this forum cause I'm a newbie and couldn't figure out where to post. Anyway we're pulling a sbc 350 out of a 89 c6000 chipper truck and putting in a big block. truck has a manual trans and we found that the bellhousing has an adapter to the block that allows for a bigger flywheel and clutch. problem is we can't find a clutch that fits the big block and is small enough to fit the bellhousing. so, is there a flywheel from gm or anybody that fits a big block that will accept a 12" clutch with a pressure plate that mates to the flywheel correctly. input shaft is 10 spline 1.365" diameter and current small block flywheel is 197 tooth 16" diameter with a 12" clutch. thanks for any help
