I think Im good here with 165hp out of my 83 gsl 12a bridgeported and a weber 48, but how can I straight out all this jumps in the chart?
Im puting on two 6al's this weekend to see what happens, i hope thats it. but any ideas will be considered.

Thanks

 

Your MSD's will help with power and smoothness. Ultimetly, a smooth power curve comes down to tuning. 165hp also seems a little low.

I would reccomend a wideband. If you have much experience with tuning Webers, it will help alot. You will be able to datalog and find out what you need to change.
