fuel injected 305 to carb 350 swap

the problems not so much the motor swap but the trans mission. The motor is a mild built truck 350 bord .030 over and has a mild cam. the trans that came off the moter was a muncie 4 speed. my truck had an 87 305 with a 700r4. the problem is the flywheel from the auto trans doesnt fit my 350 crank.doeas any one know of a flywheel I could use that would bolt to my crank and be able to use the stock torque converter?

p.s the truck is an 81 chevy fullsize so emissions and inspection do not concern me.

any help is apreciated thank you
