Want this question answered?
NO
you have eight main bolts. 10
yes
No. Never has been 1
you need a 350 put the 305 in the junk yard How long has the 305 lasted? Is it strong enough for you? If you need/want more power, go for a 350. If it's going to get extreme service (racing, heavy hauling), you might need the 4 bolt main, but probably not if it's just normal driving.
yes it does yes it does
70 ( FT. LBS. )
most Chevy trannys made for small blocks will bolt some additional information .... Chevy never made a 305 with a 4 bold main only 2 bolt main
nothing is wrong with having a 305 but if you want build it up for more power the 350 w/4 bolt mains is the better option if its for daily driving use the 305 its should be better on fuel
remove the transmission
305 sbc 2 bolt main
No way. NOT POSSIBLE NOT EVEN CLOSE
