Never Been So Happy To Hear A Motor Run
Well after so, so many set backs I finally got the motor cranked tonight. I haven't heard a big block on open headders in a couple years and I am hear to tell you it sounds bad ass. The cam is so big I am wondering if the 2500 stall is going to be enough, but that is what edelbrock told me to use. Here are the specs on the cam:
Brand: Edelbrock Product Line: Edelbrock Performer RPM Cam and Lifter Kits Cam Style: Hydraulic flat tappet Basic Operating RPM Range: 1,500-6,500 RPM Intake Duration at 050 inch Lift: 240 Exhaust Duration at 050 inch Lift: 246 Duration at 050 inch Lift: 240 int./246 exh. Advertised Intake Duration: 300 Advertised Exhaust Duration: 306 Advertised Duration: 300 int./306 exh. Intake Valve Lift with Factory Rocker Arm Ratio: 0.560 in. Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.573 in. Valve Lift with Factory Rocker Arm Ratio: 0.560 int./0.573 exh. lift Lobe Separation (degrees): 112 Intake Valve Lash: 0.000 in. Exhaust Valve Lash: 0.000 in. I also put on a set of 206 heads off a 66 396 chevelle, 1.7 roller rockers, 3/8 push rods, edelbrock pro-flo fuel injection, alabama boss hogg 2500 stall, 3:73 gears, eaton posi, patriot clipsetter headders, hydroboost off a 93 3500 chevy, 92 bbc serpentine setup and waiting on glocks new brackets so I can get the impala rear disk brakes on. As bad as it sounds with open headders I think I am going to have to get some electric cutouts so I can run a open exhaust when I want to. I still have to finish some wiring, adjust the valves, set the timing, bleed the brakes,and fix the trans dipstick leak. I will hopefully know how it performs saturday and I will let you all know.

Re: Never Been So Happy To Hear A Motor Run
The 2500 stall ought to be ok. I have run a few RPM cams in small blocks and they work fantastic. Pull hard to 7000 and still have lower end grunt. I can still pull a loaded car trailer with ease. My 68 2wd was a 350 4 speed with 3.73's and I took off like normal with the Blazer on the trailer. I didn't even know it was back there. Very good all around cam with an excellent sound.

Re: Never Been So Happy To Hear A Motor Run
Yep, uncorked BBC's are sweet - be interested how the cutouts work for you if you go that route.
