Heidi, I forgot to ask, did you install an H pipe? Shawn

Heidi, YOU just made my day!!!:) :D I think Chambered exhaust will be the next investment. That is, if i can pass emissions :mad. I've spent the last two days trying to dial it in and still no luck (she's failed twice). Tomorrow she goes to the mechanic, maybe he can tweek it just enough to...

sscam69, did you disconnect your vaccum line from the distributor then time it? I experianced the same problem yesterday. The previous owner set the timing to 14-16 btdc. I reset it to 6 btdc and it does not respond the same after i re-hooked the vaccum advance. I did notice that when i...

So i go to time the motor last night, found the timing mark, gave it some color and fire up the motor to check the timing. Well get this; my mark wasn't visible, but another mark set by someone else (?) :confused was showing up. Is it possible that the harmonic balancer is off 180 and this is...

Quacker, After i pass emmisions next week (for the last time) out with the old system, in with the new! I'm waiting on Heidi to get her chambered system installed before i make my decision - loud, really loud or too loud; that's what i want to know. I just crawled under the car and i have the...

Bill, Did you ever determine what the cause was for the vibration on your vette? (i have the same problem) I also replaced the clutch, but it's still there. Any advice would help. Shawn

I'm having the exact same problem as Tom (Tom i sent you an email). I have a 78 L48 4spd. 3200 rpms and i think someone put $10 in quarters in the vibrating bed! Any solutions to this problem? Shawn

Ken, thanks - let me know what you used for your set up Master Yoda - I was up til 1am (or was it midnight with the time change); some really good stuff there. Thanks for turning me on to the search. But now i'm confused :crazy chambered exhaust or true duals? I want performance but not an...

Does anyone have any thoughts or other on either Flowmasters or Dynomax mufflers for a 78? I'm looking converting my exhaust to a true dual with headers (no cats). Also, anyone know of a good exhaust shop in the Seattle area? Thanks ! (newbee) Shawn

Josh, I just look at my build sheet (previous owner pulled it off the gas tank) and from what i can tell my L48 4sp has 3.36 gears. I'll check the differential to be sure. Shawn

Bob, Are you running Headers or stock manifolds? I've been debating whether to run Delta 40's or 50's on my 78. I want enough rumble for people to notice, but not too much to make driving annoying. It's tough to tell on Flowmasters website; they (40's & 50's) sound the same. Thanks Shawn
