Okay here we go, appreciate any help/guidance offered. I recently picked up my first Mopar, A body, 71 Duster project car. It’s setup for a BB engine, so I found a very reasonable, if there is such a thing, 440 on FB market. It is fresh rebuilt already, see info below. Car currently has a 4.56 SG in it, but I picked up a 3.55 SG to swap. The tires it is currently running are 28” tall, but I will likely change them in the future and sell the ones on it since they’re new and I’m not planning to run it on the track except maybe a couple times for fun: M/T ET Street SS racing tires 275/60R/15.
The issue is the owner and builder of the engine have both passed away and I don’t have any info I need to figure out what flywheel and torque converter I should buy for the 727. The widow said he built it for street use, not racing. It was built by Robert Smith’s machine shop in Easton, MD. Rotating assembly was balanced, block decked, heads surfaced, crank ground, KB237 pistons estimated 10:1 comp, 413 heads, new cam bearings, Cloyes HD timing set. The rest of the parts are all high quality, but the sheet that had the Cam/liter/valve info was missing. I do not have the tools or knowledge to figure out what the cam is, but when I pulled the rocker covers it has new Comp Cams rockers installed.
It has a single plane intake, Edelbrock Torker 440, and I'm not sure if I should switch to a dual plane or not?
Also, from my research it looks like a 750cfm carb would be right for the setup since estimated HP is around 425 +-.
Not sure what other info may be useful to try and figure this out, any thoughts or suggestions?
