After a trail ride at Paragon yesteday, I'm thinking about my fuel injection / LP options for my 383. One of the guys on the previouslly had the same carb as me, he said it was nice but the TBI "upgrade" was way better. So when I start adding up the fuel injection system to feed my 383 with a LT4 Hot Cam, it gets pricey. So what are you guys feeding with an IMPCO 425 mixer? Thinking Propane may be my better option. The S10 is trail only as it is, so fueling up at the local gas station isn't a worry. And heck if its going to be cheaper than fuel injecting the motor, why not? Besides my engine is about 10.5:1 compression on steel heads, a little octane wouldn't hurt it.
