I'm just mostly familiar with small blocks and to me that doesn't seem like enough timing..
Maybe you could ask YR to help tune the carbs.I don't think you're giving those plugs a fair Shake. They were a year old and had went through quite a bit. they were on when I had the old Cam and breaking in the new one. I just got the carburetors kind of tuned in and never change the plugs or clean them. And then even worse I started it all cold with the choke on and shut it off within 30 seconds and pulled the plug out, but I thought I had said all that along with the picture...

but ya gotta ask nicely. lol
I'M thinking its rich at idle . Cam: Comp x-treme energy .500 lift , 292* dur., 244*[email protected]". Ran strong before 3" exhaust . It's just at idle , sounds like crap. Sputter, I guess . Yes 29* total timing . Thanks guys and keep up the comments . Later, Tom
since I installed the 3" exhaust I am having a skip at idle . It seems to smooth out above 2000 rpm and the pipes are black and sooty . Holley #3310 vacuum secondaries with #72 jets front and rear . Vacuum advance distributor with 24* advance and 5* at the crank .
The only thing adding an exhaust should have done at idle/off idle is reduce exhasut reversion. Should show as slightly higher manifold vacuum.Cam: Comp x-treme energy .500 lift , 292* dur., 244*[email protected]". Ran strong before 3" exhaust . It's just at idle , sounds like crap.
