Re: 1974 C20 Soon to become a project...

Well, today we took BABA YAGA! into Tony Price's shop to get the first carburetor tune. We had set the idle at about 1300 during the break in period so we would protect the cam while sitting in traffic.

I had noticed that the 350 just wouldn't pull hard from 1-2 and a punch from 3rd to 2nd was not as responsive as it should be... had to really stand on it hard. The Trans-Go kit was working fine, it just felt like we were driving with 4,000 pounds in the bed... lots of RPM's but no serious scoot!

Tony looked around and noticed that the linkage was binding, so we weren't getting WOT like we should. So we made a quick revision to the linkage, dropped the idle to 700 rpm, set the timing to 12°, adjusted the idle mixture screws and viola! All done. Anyone in the Portland area who wants a real guru to dial in your motor... You can't do much better than Tony. Besides, we talk about his drag racing while he's working, and he's always good for a story or two.

Took BABA YAGA! out and it was like driving a totally new truck! The 350 is responsive and pulls hard in all gears, shifts are firm and instantaneous. BABA YAGA! really lifts the front end when you stand on it... Man I wish gas wasn't going back up!
