I'm in the process of installing a L31 5.7L engine bored to 355 with forged pistons, vortec heads, roller cam, holly 425 cfm carb, originally from a fuel injected 1996 Tahoe into my stock 1984 camaro and I've got some questions. I've got the 305 engine and 700R auto trans out of the camaro. The guy i bought the L31 engine from said that I needed to use a 1989 camaro externally weighted flexplate to mate the new L31 engine with my R700 trans and that the weighted side of the flexplate should go toward the trans. I've done that but there's a problem with the torque convertor (TC) not lining up with the flexplate. it seems that the TC lines up with the first bolt hole in the flexplate but about a quarter inch away. Then when I turn the TC by hand the TC binds up so I can't get to the next bolt. the first couple of many questions is whether the 89 camaro flexplate will work withe the L31 and how should it be installed? weight toward engine or trans? Thanks Bob
