Agree with fbird. You built this and you dont know? or you bought it and figured what the hell.
It is nice and im sure it can be tuned to perform on the track. Open the hood and look at what you have. Do you think that will be a good cruising vehicle? 1100 rpm idle, nice. If your combo is correctly matched for that intake. It is a monster. The carb you have is a good match and probably needs some adjustment for good wide open power.
If you want a satisfing ride you might want to rethink some basics. Not that what you have cant work. The opposite can be true too.
My idea is to start stock and build up. A step at a time. You teach yourself how each peice effect the cruise and the performance aspect. Sell the old on ebay, when you advance. You will get to the ideal ride. Kind of novel, but my thing as been a mildish engine, and everything I wanted nitrous to be I found with supercharging.
