I'm trying to find a stock type oem muffler to replace the one on my 48 Chrysler New Yorker 8 cylinder (which I believe, is longer than the 6 cyl model). That would be the larger front one, as they came with a front and rear (mine only has the front). I want to replace it with a quiet oem type, no Flowmasters, Smitty's etc.... When I say oem type, I don't mean an actual NOS oem; I mean a new muffler in the oem style. If anyone has a older cross reference guide, could you post it on line? My current muffler has the following markings on it, but no brand name: T 777 and W 757 659. I've searched the web with those numbers, but nothing comes up. Thanks, David in Santa Cruz Below are the specs for my muffler, the dimensions are approximate: total length 38" body length 34" circumference 19 1/8" cross section 8 inlet num + location = 1 center outlet num + location = 1 Rt. side inlet pipe diam 2.38 (outside measurements) outlet pip diam 2.18 " " muffler shape oval

Having some difficulty setting my timing using a vacuum gauge on my 48 New Yorker 8 cyl…..and could use some guidance. I’m trying to find the timing “sweet spot” rather than just rely on the book specs. I’ve attached my vac gauge to a non-ported vac source at the carb base…(it usually reads about 17-18”)… then adjust my idle as low as I can get it…about 350 rpm or so….to keep the mechanical advance from kicking in. Did not disconnect vacuum advance because it is not supposed to activate at low RPM. Next, the procedure is to advance the timing until you get the highest rpm...just before it drops of. The problem is the more I advance, the more RPM I get…until I can’t turn the distributor any further (about 12-15 degrees (which I know is way too far). What should happen, is that at some, point the RPM should decline when the timing is too far advanced…but it doesn’t. I would expect the RPM “fall off” to show excessive advance, but that’s not happening….(FYI, points are set to specs and read about 28 degrees of dwell). The manual calls for 2 degrees ATDC, but with modern fuels I’ve been told most people run about about 2-4 degrees advance; I’m currently at 2 degrees BTDC based on my timing light. Can anyone tell me what’s going on?
