Looking for some help picking out a carb and intake for a 360 ,bored 30 over ,10-1 compression the cam is 509 lift 230-240 duration ,340 j heads 202 valves
I am going to go ahead and be the first to say this....I'll share with you my little intake secret. Eddie RPM Air-gap. Its rare to find those on small block mopars.
Street a d strip cars shod use the RPM a da 750cfm carb. Automatic cars that are more street than strip will like a vacuum secondar carb.
Automatic are that are more strip and all manual cars will like a DP Holley a bit more.
A strip only ride will like a single plane M-1 a d a DP since a thing below 3000 RPM's is ignored.
I would suggests Holley 1st and foremost as the bet ran to use with the cam. Also a 4 corner idle system would be a tad nicer as well.
My opinion is there isn't a bolt on a go carb for you combo, especially with that cam. Tuning will be a must to get the best performance and drivability from whatever you choose. You have the leaner version of the Eddy 750 where as the MDL-1407 is more performance oriented. My personal opinion would be to use the 670 Holley Avenger. It comes with a 6.5" power valve and a .031 accelerator pump nozzle. For the street it should be small enough to be responsive and the secondary opening is easily tunable with springs. Along with a Eddy Rpm or Weiand Stealth intake, it would be a decent choice, imo.
