Clutch difference for NV4500

[b454rat]

Pricing some clutches for the 4500 swap, and they list different ones for either a 350 or a 454, and even for 96 to 97. When I did the 4-speed swap in my 84, 6 cylinder to a 454 had the same clutch, what is the difference between a SBC to BBC in these??

One for a 96 BBC was $350, but for the same truck in 97 was only $200???

Dual mass flywheels, make sure you buy a disc for a solid flywheel. The dual mass discs are cheaper

Did some checking, only think that some friends and I came up with is the pressure plate. The slave was the same, disc was the same, throwout bearing, so must be the pressure plate has more than the 350. Gonna try to find out more tomorrow. I have a day off during the week now!!!!! Maybe I can finally get something done!!!!!
