I am converting my 69 camaro from a small block 4 speed muncie to a 454 with the 4 speed, can I use my old flywheel which is a 14 in. with a 11 inch clutch? Any one out there replace there heator core on an a/c camaro, what are the tricks. Thanks

the 454 is externally ballanced and requires a special flywheel or flexplate to allow balancing...
