Hey guys, looking for suggestions on a new carb for my motor heres the story...
Bought a complete worked 360 off a guy tore it down to inspect( looked almost new), put it back together and dropped itin my 72 Duster. It came with what I'm told is a 750 Holley DP that was rebuilt a year ago but the choke was milled off so I have no #'s to confirm, first is there any way to tell what it is without #'s?
Anyway the motor is a 74 360 bored .030 with what look like slight domed and milled hyper pistons( was told they were forged but look like hypers). J heads with 2.02/1.60 valves with a fresh valve job that have a nice porting on the runners but not much bowl work. I cc'ed the heads at 68cc's which brings the compression at 10.07:1 . It has a Racer Brown SSH-25 Hydraulic cam (238 duration @ .050 and .485 lift on intake/exhaust with a 108 Lobe separation),1.5 rockers, Holley stip dominator intake with a 1" 4 hole spacer and the Holley 750 DP, it also has a Miloden deep pan and windage tray. It has an MP distributor with a Crane High 6 Digital box.
This is all now in a 72 Duster with a close ratio A833 with an 8 3/4 with 3.91's and a 325/50-15 tire (28" tall 13" wide).
So I'm still breaking in the clutch(Centerforce Dual Friction) so I haved stomped on it yet, but it seems like a beast of a motor for the street. The carb seems ok, but there a slight stumble when you hit it, and I dont like not having a chock for a street car, take too long to warm up and have to hold it at 2K for a min. or 2 before it will idle on its own. So I'm looking into a different carb seeing as its a modified carb thats been rebuilt and had the butterflies drilled.
So what would be a goot carb for this setup, I was thinking something like the new Holley Ultra 750 DP with electric chock, goes for about $500 which is steep but I'd rather have a quality carb but not much more $ than that. I ran a 750 Speed Demon on my 68 Satallite wit a 440 and loved it, should I go Holley Ultra, 650-750 Speed Demon( I know they flow more than advertized) or something like a Quick Fuel? What do you think?
Last owner thought the motor was pushing over 400HP and with a more radical cam put a 68 Coronet in the mid 12's.
