I have a 408 stroker, 770 holley carb, dougs headers, rhs heads, dl plain intake, crane ign box. The car doesn't run well at all and I cannot get it tuned right. It bogs down and almost stalls when I punch it and is unreliable. Looking for it to run great. No need for a fancy dyno tune. This motor has set me back some $, so I'm light on cash. Any ideas for a good inexpensive shop?
