8 degrees.
Either 145 with the base 305 4bbl or 165 with the 305 Crossfire injection option
The base 305 had a 4bbl carburetor
stock timing on a 400 small block Chevy 2/4 bbl engine is 4 degrees btdc. depending on how the engine is built however, i.e. rebuilt to stock or built for performance, the timing may be up to 8 degrees plus or minus tdc or more depending on valve timing and cam timing.
The base 305 4bbl had 170, the H.O. 305 had 190 and the 305 TPI had 215
most of those engines were either 265 or 325 hp.
You need to check the fuel pressure and the fuel FILTER.Most common cause of that is the float level in the carburetor is not adjusted right. / not getting enough fuel.
I have an 82' impala wagon and the factory 305 4bbl that is in it is rated at 145hp.
The 1996 4.3L engine doesn't have a carburetor, it is fuel injected.
1970!!! Geez... "0" degrees I think. Better call your local auto parts dealer and ask to be sure.
