Re: Is it a 305 or a 350?

Just get up in the motor bay look behind the driver side head and it will have a long number or 5.0 or 5.7

for example the long number will be like 397000(this is a old 350 block)

If you have a number and cant figure it out let me know I can get it for you

we have all the old gm code books

Re: Is it a 305 or a 350?

There's really no way we're STILL talking about this? It's seven f***ing years old now!

But I've got a question actually, regarding the size of the engine from the outside on my '88 Formula.

What if there's no paint on the block and it's gray, and the casting #s are in different spots, and the balancer is the pulley too, and it has a large "5.3L" cast on the front of #1 cylinder?

I think it means 305's suck hippo a**.

Stock.

Re: Is it a 305 or a 350?

Well this is old but i really need to know. Is there anyway to see the casting number on the back of the engine without removing the engine??

Re: Is it a 305 or a 350?

sometimes you can. if you can't and need to know what the engine is, on the front passenger side of the engine right in front of the head is the suffix numbers and they can tell you what vehicle it was originally in. thats if the block wasn't decked

Re: Is it a 305 or a 350?

So those numbers will be on the block not the headers right? and closer to the back of the engine or the front?

Re: Is it a 305 or a 350?

VERY EASY. when you start the car, a 305 will crank over 4 times but a 350 will crank over 3.5 times before firing, duh. i also heard something about casting numbers, but since no one has mentioned it, cant be right, lol.

On a 305 the muffler bearings are on the drivers side and they don't have a grease nipple.

Re: Is it a 305 or a 350?

It's typically in the back, on the driver side?
Anyhow, this is the best list for casting numbers I've ever come across (including the one on this board)
