An oldie, but a goodie- have fun.
The ignition timing is 4 degrees before top dead center. Adjust the point dwell to 30 degrees and the adjust the idle speed. then disconnect the vacuum to the vacuum advance and set the timing. Reconnect the vacuum and fine tune the carburator.
With an upgrade to electronic ignition and with running todays gas (low octane) a bump up in timing would be recomended. Try running about 6 degrees after and see how it does would not go above 12 after.
6 degreed advanced or BTDC.
302 small block Chevy
your dwell angle will be 29 timing ( initial ) will be 6 degrees below TDC
350, to 400 lbs.
There was a 396 available in all Chevy trucks from 1968 - 1970.
its either ur timing belt or ur sparkplug wires r wrong
285, to 300, according to the factory.......
It will bolt in the same as any big block Chev
my corvette book says it should be for basic 4 deg btdc
if it has an automatic its 4 degrees before tdc, with the vaccuum advance off and plugged
I would set it at 10 BTDC with the distributor vaccum unhooked while setting timing. 10 to 13 degrees is what the factory recomends.
The legendary 1969 ZL1 427 big block Chevy had a bore/stroke of 4.25" x 3.76" , while the newer LS7 small block has a bore/stroke of 4.125" x 4" , both of which feature aluminum heads and block .
