Need some help dipping into the 11's
Some helpful info would be:
Do you have the incrementals from a time slip with 60', MPH at 1/8 and 1/4 (that would be REALLY helpful)?
How much does your truck weigh?
What gear?
What compression?
What cam?
What converter?
What jets are in the carb now (and what size is it)?
How much carb tuning have you done with the combo?
A vacuum secondary carb WILL slow you down more than likely....
If you need help tuning it you could bring it out to Lucas Oil Raceway on a Wednesday night test and tune and I could help you out if you like....assuming I'm not tied up with running kids to sports and such. There is also a race on August 17...sounds like you would fit in Sportsman quite well...Always nice to see other Mopars out there.
