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.
how to set the timing on 1978 f100 ford 400 engine
most of those engines were either 265 or 325 hp.
305 heads of course, 350 heads will fit for sure and possibly 400. obviously no big block heads will fit. a 305 with 400 heads gets you a little over 352. 350 with 400 heads is a 383. add and divide
400 ci Chevy, 400 ci Ford, 400 ci Chrysler, need to know which 400.
4, to 6 degrees advanced, or BTDC.
The 400 ci sbc was produced from 1970 to 1979 and had HP ratings from 150 to 265. If your question was more specific ie: year, model, 2 bbl, 4bbl,etc. I may have been more helpfull.

It will work, but you would need a 4bbl intake or an adapter plate to fit the 4bbl carb on a 2bbl intake. There are many 4bbl intakes for small block Chevy's available in the aftermarket, or even the junkyard. I would recommend just getting a different intake instead of adding an adapter plate due to possible clearance issues between the hood and the air cleaner. yes it dousent matter what the carb sizes are when it comes to the same size of motor for space the only problem you should have is that the headers may need to be replaced for spaceing but for other jobs like this a 302 block is the exact same size as a 400 block jsut bored out alot more
30 degrees and 8 before tdc
They usually have a TH350 or 400 Transmission Very common to come by
either a 285 or a 350... the odds are that its not a turbo 400
4 degrees BTDC / Before top dead center.
