18 spline A body 4 speed
If you have that much HP in a heavy car with sticky tires I would get a hemi box. But Make sure your getting the 18 spine bushed gear sets from passion.
I build 4 speeds and Dan from Brewers never steered me wrong any info. I would call him and explain my dilemma and he would always have the correct answer to solve the issues I have. If he was out Cindy would always have him call back, He took time called me and talked to me on the phone.
I have several Hemi box here including A-body. They sit on the shelf. Heads up and Gassers race cars are usually 4 spd users. Big HP bracket cars go automatic.
I have put Hemi engines and 440's in 383 street cars with 23 splines . The weak link was always the 741 pinion shaft on the 8 3/4 rear . A good 742 is what worked. Or a 489 with the early 741-742 clutch style power lock. The 69 and later cone style sure grips are throwaways and usually slip if one tire sticks and the other don't.
