Sure would be nice if NHRA allowed edelbrock or Mopar Performance to recast these in aluminum.

I have both the low and high block mani's. Yeah they're a bit on the heavy side but they actually work quite well considering their age. My low block one is dated Nov 57, it came off a 58 350 Fury like the one in the movie Christine.

Let's see, I see old school 'white painted' fenderwell headers as well as the short velocity stacks on the carb...just curious but I wonder if any of these old racers got away with any 'hidden tricks' that they used on these 383/343 hp engine combo's...as for the intake manifolds, did they ever cast any in 'magnesium' paint'em and try to get away with it back then, lol.

I found this old post in another thread on here...

Moose,

You're always digging,,,,,,,,,,;)

1970,
The 62' 383/343 HP Plymouth Belvedere Station Wagons were lighter than the 62' Dodge Model #440's.

The Plymouth Wagons ran in G/SA in 1970 and 1971, with the 340 Mopars.

It's a nice thought, but we need to stop dissolving what little is left of stock eliminator. People keep asking for changes and NHRA will gladly get a rid of us just as they did junior stock and modified. They would love to get a rid of us. We are a hassle for nhra and they would love another bracket class.

You guys talk about expense on vehicles. Trust me I just finished a 62 383 343 belvedere and 50,000 won't come close to cutting it to build one of these cars right. It is not much cheaper than building a drag pak challenger

Re: 1962 Mopar 383/343 HP 'Stocker'
 

I know this is a touchy subject with some of you but these parts are 50 years old now and if it's this hard & expensive today to find the correct parts, imagine what it will be like in another 10 or 20 years from now... I know because I was in the parts business for almost 30 years and it's getting tougher and tougher to find the correct stuff or old iron... It looks like "time" is the enemy here, so maybe if NHRA could bend the rules a little or allow 'spec parts' and work with the racers to make it more affordable, I think it would make it more fun for everyone involved... Anyone else here running a 383/343 or another stocker combo that feels squeezed out and has had to run in another class, because I've heard of a lot of people that just dropped the 383/343 combo and moved up to a 426 Max Wedge or 440 Six-Pack motors...so it would be nice to fix the problem now instead of eliminating it all together later.

Pic of the first 383-343 motor... Jim Johnson then Rick Johnson.

E.B.

The #3258 Carter AFB has a bigger Secondary Venturi than the #2790 Carter AFB.

1.250" versus 1.125"

I'll check on the jet sizes and other specifications.

Both were rated at 500 CFM,,,

By the way,
Joe Kenney (August 9, 1964) was classed in B/SA with a 61' Plymouth
413........
Won B/SA Class @ Dover Drag Strip with a 13.91.
