Reg Evans Posted March 9, 2007 Report Posted March 9, 2007 I want to try this manifold out on my 230 engine in my 38 Coupe and wondered if ya thought an original 56 Plymouth carb would work any better than one of the Langdon 2 bbls. Anyone know the type of carb that was originall used on the 56? Quote
greg g Posted March 9, 2007 Report Posted March 9, 2007 carter bbr. same as what was run on the small v8 in 56. I got a rebuild kit for my 56 engine's carb and it came with the stuff for the two bbl. I think it is still here if you want it, let mr know. Quote
Reg Evans Posted March 9, 2007 Author Report Posted March 9, 2007 Thanks Greg ! I will take you up on that kind offer if I can find one of them there Carter BBR's. Quote
greg g Posted March 9, 2007 Report Posted March 9, 2007 You can probably use any 2bbl from a 273/318. Think they were also used on the /6 power pack equiped deals. Should be availabe in the millions in bone yards. Common problem is eliptical wear of the hole in the body at the throttle shaft pivot causing eratic idle. Look for ones with good round holes Quote
Olddaddy Posted March 10, 2007 Report Posted March 10, 2007 Reg, how does the size of the center body compare from your 2bbl to a 1bbl? I was thinking it should be possible to mill off the mounting boss on a 1bbl and mount a 2bbl. Could you measure yours for me? Quote
Reg Evans Posted March 11, 2007 Author Report Posted March 11, 2007 Charlie, The center body on the 2 bbl manifold measures 4" and the center body on my 1 bbl measures 3.25" Quote
Olddaddy Posted March 11, 2007 Report Posted March 11, 2007 Thanks Reg, I guess an intermediate plate would be required if using a 1bbl intake for 2bbl purposes. The Langdon setup looks good and his stuff is well thought out. I suppose the simple route would be via Langdon, but I would like to work out something really simple using existing intake and linkages. It looks like his setup raises the 2bbl carb to the height of the 1bbl carb, that may be a good reason to use an adapter. More thought required on this one. Thanks again. Quote
grey beard Posted March 11, 2007 Report Posted March 11, 2007 It'd be nice to know how CFM air flow compares between a single two barrel and a pair of singles. Anybody know this stuff? Thanks Quote
greg g Posted March 11, 2007 Report Posted March 11, 2007 This help??? Here is a comparison of the gaskets showing the throttle plate area comparison, my guess is the two 1 bbls have more area. Quote
Reg Evans Posted March 15, 2007 Author Report Posted March 15, 2007 Thanks Norm. I've got my eye on it. Quote
