My car is a 1970 with a 68 383
10-1/2-1
Looking for a 68 carb to match Up Engine, will a 440 carb work?

AZ Desert,
68-69 Road runners with a manual used a carter 4615. Other 68 383 manuals used a carter 4426 according to my book

Not sure of any differences but yes a 440 carb will work.
Cool do you have any or do you know where I can get one I was going to buy this one in California for 100 bucks that kind a looks OK but it probably needs a rebuild I think it’s at 4:40 1970 carburetor I just want to make sure the choke hooks up

Those were coming through with Holly’s also, replaced mine and seemed to be better than the Carter. 5 more HP, at least that was the consensus half a century ago, hmm.

Yes true I forgot about that.
What CFM Holley or carb number?
I just got a 600 CFM with electric choke for free it’s a polished carburetor I put it on for now

Cool so that should work.
Probably and 71 the 440 was detuned comparable with the 68 383 engine?


Yes, believe that’s when compression ratios were lowered, more smog stuff added, unleaded gas in use and went from Gross to Net horsepower advertising. A lose-lose combo. Oh too, the tamper proof carb screws showed up around then also. Always wondered how a Spread Bore would work with the larger secondaries- never tried.

Gorgeous, I’d keep that if it’s working good. Can’t recall CFM but close to Carter, learned not to overdo on bores. My ‘Lil Red Truck had a good Carter with phenolic body to keep fuel cool, had vapor lock back through the 60’s, ‘70’s with hot engines sometimes.

Yeah I priced it it was about 300 and change I just had a Mustang that I’ve acquired and it had a lot of extra parts with it so I got this for free.
My old one had no choke

i think the Larger secondaries would be great reminds me of a quadrajet carb.
