1966 Plymouth Belvedere 383 car

Hey Guys,

Been toying with the idea of putting a legal 383 motor into my Nostalgia Super Stock 66 Plymouth Belvedere post car. I currently run a 400 based motor with indy heads, so a 383 would be the "easiest" build in my opinion. I run leafs, 8 3/4, 9" slicks, etc.

I have followed NHRA stock/ super stock for years, but to be honest I am not great with the class determinations. I believe my car with an auto and 383 would fall into a natural I/SA, correct?

I am looking to buy a motor.. nothing record setting, just something to run divisionals, combo races, and maybe some of these big money races. So if you know of any... let me know!

Am I correct in my I/SA thinking here? 12.30 index

Thanks guys,
Casey Fauss-Johnson
