Hey

I am planning on getting a 383 stroker built this winter and the engine is built to put out 400ft/lbs at the flywheel. I am wondering if the stock bottom end is going to be able to handle that power or am I gonna blow it to nothing.

Thanks alot.

 

A stock one? nope.

One rebuilt and upgraded to 87+ specs? Sure.

 

I have heard that the 1985 700R4s wernt as strong as the 1987 and up 700R4s, I forget what its called of the top of my head but somthing in the 1985 700R4 twists.
How long do u think the transmission would last with the 383. Ill be braking the motor in so I dont think I will be bagin on it.

I think it is the input shaft, Ibeleive the earlier trans. have 27 splines and the later ones have 30 splines.

 

Yeah thats it. The imput shaft is weaker then the 1986 and up.

 

I thought that they went to the 30 spline in 85, and that it was the 84 and previous that had the 27.

 

I think that 84 1/2 was the change not positive though.
