I rebuilt the top end on my 1994 351 Windsor and I'm not sure I've gone the right route in relation to the cam. I need some feedback from the engine gurus that hang out here. Here's the background on the engine. It was a fuel injected truck engine from a '94 f250 and I put on Edelbrock Performer RPM heads, a Performer intake, a Holley 650 DP, and a cam from Cam Motion. Here are the cam specs:
grind# x2201-2182-10
intake:
Dur- 220.8
Lift- .54255
exhaust:
Dur- 224.2
Lift- .54299

The cam is supposed to come on hard at 2500-5000 rpm. Anyway, I put this all together in 2005 then put my car in storage while I was overseas in the military. I never really got a chance to drive it because I had other parts of the project that weren't completed. I just came back to the mainland and got my car to my new house and it drives horribly. At medium to full throttle it bogs so bad that it almost stalls. I'm going to clean the carb and see if that fixes the bog but it also misses if you stay on it out of the bog. If you rev it to get the rpms up it runs strong, but you have to feather the throttle. You can't just come off idle strong. The cam profile wouldn't have anything to do with this would it?

Brad,

It sounds like you might have some tuning issues. I would start with the basics. Make sure that your carb is tuned right. Double check the timing, plugs, and the rest of the ignition system. Does the car have manual or automatic transmission? A vacuum secondaries carb might be a better option for a street car.

Yeah, I think it's probably the carb. It's been sitting for almost 8 years with nothing but an occasional start up and a bunch of ethanol flavored gas. I'm thinking about switching to an Edelbrock 1407. We have one on my wife's 383 with a real similar cam/cylinder head combo and it purrs like a kitten. I'm gonna start with cleaning the Holley, then go from there.
