FredT, it means you're a bi-bolter.
What's all the fuss! This place is like the corner gas station where guys (and gals) can come in and gain knowledge and/or give it. For me it would have been darn near impossible to get my '69 c-10 with the 250 l-6 going, but its going and I now know more than I knew at the beginning. Hell, I've even given some advice on this board and others. Glad to help out.

Rules are rules, but more importantly people are people. Someone wants to drop a LS-1 or chevy 502 in a '46, cool!
