You can run any size carburetor you want,however for maximum performance we would need more details on the engine,trans,rear end,and how you plan to use it. That being said any quality 850 mechanical secondary carb will give you adequate performance once tuned to your engine.
Back in the 90's for a short time I had skinny's on the front of my 72 Nova. It did not instill any confidence turning at any speed above parking lot mph. I couldn't imagine skinny tires on the front of my 73 Charger at the time. Much more weight. I have 6" on the front of my 72 Duster now and...
What other parts do you already have that you were considering?
Based on what I am hearing from you I would recommend;
Better heads (if nothing else) ,One size smaller cam (maybe have Dwayne Porter do you a hydraulic roller designed for the exhaust manifolds), and 3.55 gears. Won't need quite...
Depends on your budget and what parts you may already have. Either is fine and neither will be cheap.Pump gas go with the big block.Boost go with a modern hemi.
A 66 Charger should have an old school engine.Just my opinion.
The 346 was the introduction of semi hardened seats for the unleaded gas IIRC. Stock for stock I don't think there is much difference in flow.Still an open chambered head with cc's between 85-90cc in un modified form. The cc's you posted may be nhra blueprint spec/may not be but any open...
Let's see, Sharon Harris nuclear plant 30 miles away, Fort Bragg and Pope Air Force Base an hour away,Camp Lejune and Cherry Point 3 hrs away,and Seymour Johnson AFB maybe 2 hrs away. I sleep well knowing if it goes full tilt I won't feel a thing.
Every time I have run 2" headers I have slowed down.Tells me I don't have enough motor,stall,or gear. Or all three lol.
The first two applications were heavy street cars and it just killed the bottom end. One car I went to more gear and the other car back to the smaller headers.
My pig of a 72...
The best X pipe IMO was the Dr Gas X pipe.Seems they are now defunct. I ran the same one on two cars and sadly it was on my Polara when I sold it. I prefer the magnaflow tru x these days but they are triple the price of the China knockoffs.
1.Cheap knockoff
2. magnaflow
3. magnaflow 70 degree
There was a thread not that long ago on the A body site (I think) where someone had a rowdy big block with flowmasters and it was too loud and droney. He put long glass packs in front of the mufflers and it tamed it quite nicely. I was impressed with the difference and I am not a Flowmaster fan...
I have been selling tires for the last 18 years. My greatest fear is someone's tire coming off the car. In 18 years (we are a very busy shop) it has happened twice. Two times too many.
Ch4b had no problems on my 496 stroker clearing my C body flat hood with a factory air cleaner.Had no problems turning 6000rpm with it either. The Holley street dominator cleared as well but I opted for the bottom end of a dual plane on my heavy c body.
I think either would work well and the...
I would try what you have first. It would likely handle a 600 or 650 just fine. Get your headers and gears first and tune what you have before making another change.Just my opinion.
