Im putting an 87 GN motor in my 87 MonteCarlo.......trans?-I have a built th350 trans in my Monte with high stall converter (stall unknown)...I wanted to use my th350 since its ready to go, I know I may need a BOP adapter plate, but will the torqe converter slide in place and bolt up to the flywheel without any problems?...would I need to take the flywheel off the 350ci and put it on the buick motor?...also with a 3 speed setup does this have a performance advantage over a stock 4 speed setup with these TurboBuicks?...as if they both had the same stall, im just saying whats better for the 1/4 mile a stock 3 speed or stock 4 speed?...also what about the kickdown cable?..is there a universal kickdown cable or will the 4 speeds kickdown bolt up to my 3 speed, because I dont have a kickdown cable in my Monte, I do it by hand...do I even need it for the GN motor, will this trans effect the computer at all?
