89 GT / will a 5.0 truck motor work?

[miskae]

Motor change - can you help?
I own a 89 GT conv. 5.0/auto that needs an engine change.

I also have a very low mileage 5.0 truck motor.

I installed a new cam and got the motor ready to put into my car but then had problems when bolting to the trans? It seems there is a problem there.

It all lines up, but when you tighen the trans bolts, the engine, flex plate and convertor will not freely spin.

I cannot see what is binding it and need someone to tell me if I have done something wrong and if so, how to correct it.

Thanks, Robert miskae@tiki.net
