So I own a 1970 cutlass and I wanted to go with a 455 engine but couldn’t find one so I ended up going with a brand new 383 Chevy smeding hod rod engine that I came across with for a good price know I’m wondering what would be the perfect transmission to use I was looking into monster transmission maybe a turbo 400 ?? Help what would you do I know it’s a Chevy but aye I couldn’t turn down the price of the engine and my 350 rocket just doesn’t seem to give me the speed I want help
