Some will take up to 54 degrees advance under these conditions. Once you advance the timing beyond this, the engine/car will start to "chug" or "jerk" at cruise due to the over-advanced timing condition.Set spark timing at 10º Before Top Dead Center (BTDC) at 700 RPM with the vacuum advance line to the distributor disconnected and plugged. This setting will produce 32º of total advance at Wide Open Throttle (WOT). The HEI distributor supplied with the 350 HO engine has mechanical centrifugal and vacuum spark advance with the following curves:

Jul 23, 2009. #8. If you installed the dist w/the timing gear mark at 6 oclock and the crank gear mark at 12 oclock (which is correct for installation.), then it is 180* out. You would have needed to rotate the engine 360* to get 1 to TDC on the compression stroke (timing gear mark @ 12:00 & crank gear @ 12:00).There's a dowel pin on the cam and the crank has a keyway. If the dots are lined up you can't screw it up. Then get your #1 piston on TDC compression stroke (your timing mark on the crank should be close to zero). Drop the distributor in and the rotor should be pointing slightly before the #1 position (it rotates clockwise).Search: Chevy 350 Tbi Sluggish Acceleration i have a sbc 350 with an edelbrock top end kit. p.n. 2908. i called edelbrock and they said to set base timing at 12-14 degrees BTDC and the total … read more George H.
