I've just rebuilt my 383 in my 70RR and am looking at getting a new carb.The engine is running a Comp Cams hydraulic flat tappet XE274H...488/491 valve lift.It's an air grabber car so I went with the Edelbrock DP4b intake.It's bored .030 over,flat-top pistons and stock HP exhaust manifolds through an entire 2 1/2 mandrel bent system.It's a 4-spd with 3:54 gears and I was thinking along the lines of a Holley 750 double pumper or a Quick Fuel HR series 750...anyone with any experience along these lines?
I'm a novice at this so if I missed something take that in mind...I was figuring a 750 DP would be good.I'm planning on TTI headers down the road...any help would be great,thanks
