Makeing a jump with new settup from 4wd to 2wd and just looking for some insight

Wow, haven't seen you post in a while. No insight but wonder why the change.

Personally lost interest in 4wd, my opinion is twd is much more puller settup involved

I bet. Gotta compensate for that lost weight up front for traction and steering. On the plus side you gots more power!

Always been a rb guy but now I have drop to a b block and the parts struggle for a 383 is real

Do you have to switch because of a cubic inch rule or personal reasons?

Well kinda a long grey story, never less I'm going from a 475ci class to a 410ci small block only class, have fought for two years that cubic inch is cubic inch big or small block, they won't budge claiming I'll make so much more torque with bb, never less it is a Chevy 400 run class so had a 383 kicking around and got the go ahead to run what I call mopars 383 mid block kinda like the Ford 351 so just throwing together a used parts special, yet finding 383 parts is a struggle
