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.
most of those engines were either 265 or 325 hp.
The base 305 4bbl had 170, the H.O. 305 had 190 and the 305 TPI had 215
I have an 82' impala wagon and the factory 305 4bbl that is in it is rated at 145hp.
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.
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.
Z-28 - LG4 305 V8 165 hp (sold in California only) Z-28 - 350 (4bbl) V8 175 hp

When it is working, go to autozone.com and they have diagrams. Or go to MOTORLIT.COM. 4bbl A/T Calif Emissions No, it does not. Please be accurate on your answers.
Either 170 hp w/5.0L 4bbl, 190 hp w/5.0L 4bbl H.O., or 205 w/305 TPI.
I have a 1969 el camino 396 ss new holly 4bbl, timing set correctly, and sometimes gives a pop thru carb. please tell me the items to check over.
not sure of all makes but they were widely used on 80-82 camaros and similar F-bodies (firebird etc) I have a 1977 Firebird I pulled my complete 350 engine from a 1978 Camaro and with it came a 4bbl Q-Jet by Carter. The owner of the camaro said that is what the car came with and it was all original. Hope that helps.
There is no definite answer to that. The book will probably say 10* BTDC but I get the best performance and no pinging at 15-16*. I think the book is usually pretty conservative. This sounds old school, but you will get the best results by timing it to best idle, then backing it off a hair at a time if it starts hard.
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
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
checker auto store
150KM (2bbl) 170KM (4bbl)
clean, replace e.g.r. valve, tune up or replace catalytic convertor.
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.
The largest engine that year was the 350-4bbl V8.
Could be the idle is set too high, maybe the mixture screw passageways are plugged up.
