Dissapointing performance
Yeah, WOW! I'M Dutch and I thought I was stubborn <grin>
You need to listen to these guys or figure it out for yourself. You don’t have a big enough carb, you need bigger exhaust, converter stall too low (should be 2800-3000) and if you showing 20” vacuum at idle something is way off with your cam…..
The fact you can't smoke tires really points to the converter and cam. Good luck.
