I am building a 1957 Chevy Hardtop with a 1968 327 and a 700r4 trans. I was assembling drivetrain and discovered the flywheel (flex plate ) for the 327 will not bolt to the torque converter for the 700r4. I have been told the bolt pattern is the same on all converters but this does not appear to be the case. The 327 had a powerglide trans originally and I assume this is the same flywheel. Has anyone had this problem before and how did you resolve it. Trifive is a great site and everone is always so helpful I am hoping someone can help me solve this puzzle. Your help will be greatly appreciated.
