This is good stuff. Someone needs to arrange this info. and make an archive reference for it.
The real issue (for me) with a big block and power brakes is going to be the lack of a decent vacuum signal,lol...most guy's running big blocks want big power,and that needs a big cam.
Idk if those really big motors will work for me...451/470 budget motor fits my bill..
The defroster dash vents in early a-bodies are the same as 70's dodge vans.
I saw a early model Dodge Viper which also looked like early A vents. Jayson
I need vents, I'm Guna look for a viper parts car ;)
You're bound to save loads of cash!
