Hey guys, I'm finally going to be home some for the summer and able to work on the 'Stang again! First project.... get her running right!
Here's my current setup.
200 six
Clifford dual outlet headers
2" duals with turbo mufflers and Hpipe
Load-0-matic dizzy with pertronix, coil, and wires
Carter YF
8" rear with 3.50:1 gears and the crappy 2.77 3spd
And here's the problem... acceleration is really sluggish off the line and gas mileage is pathetic. 2nd and 3rd gear pull fairly hard and she runs fine on the highway. BUT, I only get 15mpg in town or on the highway..... and I think thats uncorrected for my speedometer so it could be 25% lower!
Its been awhile since I did the tuning but it seem I dialed in 5* advance over stock specs. I tuned the carb to give max vacuum at idle and have the dizzy vacuum port connected to the only port on the carb.
I plan on replacing the belt driven fan with an electric to help both power and efficiency but also to cut down noise some. Between that fan spinning full RPM and the exhaust long 75mph cruises are nearly deafening!
I'll probably replace the YF with a 5200 by the end of the summer, but in the meantime I need to see if I can squeeze out some better mileage.
So, suggestions guys?
