he will be sending a holley 750 double pump that they use on the there small blocks. i like the look of the BG's and the improvments.

So for this engine backfiring thru the intake is because of the cam being 4 degrees more than your recommended specs of 220?

what carb do you recomend for this engine?
i have seen other 383's with bigger cams running close to 460 hp being ran off the 625 road demon with 82 mains.

why does a big cam have an effect on how a carb runs? you would think that if its because of lack of vac. that you could tune for that.
