Hey guys, new to the forum and to street rodding. My wife and I had her grandpa's old 1950 Studebaker pick up built into a mild street rod. We put a Chevy 350/290 HP crate engine with a 650 Holley. The guy that built it put on a used Eldebrock intake he had instead of the intake that came with the engine. I've got about 50 miles on the engine.
I was messing around with my timing light today, its digital with a tachometer, anyhow with the vacuum disconnected it runs about 860 rpm when I hook up the vacuum it jumps up to 1200 rpm, is that normal? Like I said I'm new to this, the reason I'm messing with it is it stutters and hesitates when I accelerate and I'm trying to figure out whats going on. A friend of mine set the carb with my vacuum gauge, but I think it idles too fast too. Any help guys? Ideas?
Thanks
Kenny
