Butterflies...BUTTERFLIES???? WEE DOAN NEEED NO STEEEEKING BUTTERFLIES!!

Parts that don't exist seldom fail, and they don't cost anything. Such is the case with my secondaries. Couldn't be happier in that regard! But! indigestion is certainly what #8 has. God willing and the creek don't rise, gonna give the pull a hard charge - or at least get as far as I can go in one weekend - assuming nothing simple (read: non-mechanical) surfaces (but I doubt it!).

Jerry,

I thought of that. When I did mine I counted an odd number. PANIC! Found it on the bench.

Yeah, I sweated some bullets on the first couple. After that I placed my magnetic "grabber" right on the butterfly as I removed the screws...Just in case. At least no butterfly screws went "south". AND...I drove it for about 600 miles after I put the plenum/IHs back on, and she ran like a scalded dog - no missing.

Thinking back tho, on one of the last times out before putting the headers on I went to down-shift and missed a gear - pegged the tach for just a second. I wonder... It will be interesting to see what's going on. I'll take some pix. At this point I'm not dreading anything - just itchin' to get in there and see whazzzup!

Several companies that rent bore scopes Paul, that might be an option.
