There are a couple ways to tell short of tearing a head off the engine and measureing a cylinder.From the factory in the 80s a 305 timing pointer was at the 12 oclock om the balancer and a 350 was at about 2 oclock.Also on the back of the engine where the trans bolts to on the driver side behind the head the 80s engines would be cast in 5.oL for the 305 and 5.7L for a 350.These arent always sure fire ways but alot of times its worked for me the only definite way to tell is pull off a head and measure the bore the 350 is a 4inch bore

u can listen to the engine
If the Buick 305 is really a Chevy 305, then the motor mounts will interchange with a Chevy 350.
Yeah.
No they are the same blocks.Where did you get the mounts on the 350 from? The 305 or junk yard?Is it a new 350 or older 350?
Look at your timing scale the 305 times from behind the water pump & the 350 times in front of the water pump.
How can you tell a 350 from a 305 engine?
No. It's probably the same thing.
Yes they interchange
Both are strong engines, but the overwhelming consensus is that the 350 is a better engine, and I agree.
Oldsmobile used Chevy 305's. 76 350 rocket 77 305 Chevy
