I’ve been watching this string with some interest as we’re finally shipping the new Poly dual plane hi-rise ‘wind tunnel’ manifolds and finned aluminum valve covers… I chuckled to myself, “he’s got a vacuum leak-he needs a new wind tunnel manifold”… and not to make light of the situation at all… I’m with you on the vacuum leak be it internal or external… When we start pushing parts around and having them machined, a couple of degrees surfacing here and a couple there and then the manifold doesn’t fit as snug as it is supposed to… If you are using the tin gaskets that could be an issue to… We do not recommend the tin in any event… We use and sell only the composite for the intake as well as the valve covers… The final frontier is the cam-where did you get it and are you sure its not for an early Hemi or small block??? The cam card says it’s for a 383… There’s your trouble??? From: 1962to1965mopars@xxxxxxxxxxxxxxxx [mailto:1962to1965mopars@xxxxxxxxxxxxxxxx] On Behalf Of JimJablonski Another update: - Quite sure the distributor is not 180 out given I held my thumb over the #1 hole when I rotated up to TDC and felt really good pressure. Based on previous experiences I'm pretty sure I would have turned the motor into a flame thrower if it was 180 out (?) - Quite sure the spark plug wires are correct but I checked again. And again. And again... :-p - I swapped in an old distributor, same results - I swapped in an Orange box, same results - Ran a ground strap directly to the Orange box (now on the car in place of the Chrome one), same results I've got myself talked into pulling the front of the motor apart this weekend and looking at the timing chain / gears and re-degreeing the cam. Ugh. What's driving me here is the fact that it won't start unless it's advanced to approximately 50 degrees. (Again, once started, when I retard it down to 30 or so, it stalls out.) The one thing that's bothering me is that it runs relatively OK at start-up when the choke is on (even though it is way over-advanced), then worsens as it leans out while the choke heats up and opens. I know many would say this is probably a vacuum leak, but I don't see one. Besides, why does it need to be so far advanced before it will start? If it was a vacuum leak, it seems to me that it would start in the "normal" timing range, but not idle. BTW, team, check something for me? I attached the cam card. The way I am reading it is if I install it straight up (not advancing or retarding it with bushings, etc.), it will be 0 advanced. Does that look right to you?
