whistling question

I'll be waiting on your no vac timing numbers, but i will add a few thoughts. I know you want to up the power at some point but the combination you have right now is pretty well thought out. With that said, to get the most out of what you have now........As far as timing there are alot of opinions here, member crackedback likes to put as much initial in as it will take and not surge and still start and then limit the total. That is a sound thoery and something you can work with, but for now just to get it running pretty well based on approx. 9to1 comp, the cam, intake, converter and rear gear you have i would recommened around 14-16 initial and about 40 total on the timing. This is just a general starting point for now. As far as the carb goes it's a little small but can be made to run well with what you have. Would leave 10-15 hp on the table at peak power but that can be addressed down the road. A change to a lighter secondary opening spring would probably help.
You spoke in another thread that you would like about 450 hp. and that is certainly doable, but your gonna have to change alot of the combo to get there. I would optimize what you have first then consider what it would take to get to that point.
