318 I D needed

[RAT ROD AL]

Here are the only #s on the block. I know it's a 318, but as you can see in the 2nd pic you cannot read the year. The vin pad is not stamped with any #s

Here is the balancer and crank. Is the balancer for a forged crank, The crank looks cast and has stampings and cast in #s. I'm thinking .010 on the journals. The rods and caps are not numbered , but has weird stampings on them such as , one has a star, one has a cone, one has a wine glass, another has a # and so on. ( maybe a warranty rebuild ?) Casting #s on the rods are 3418645 (common 318 ) and has .030 pistons, only # on those I see is
B285 up inside, flat top with 4 valve reliefs . Look like sealed power pistons maybe. What C/R ? Any and all help is appreciated . What year did the 318 go to a cast crank ?

Casting date 6/23/73??

I was hoping there were some other #s there that could be deciphered.

It's a 318. They didn't come in many varieties. There should be a vin# pad the deck surface. It should have the last 8 of the vin. That won't tell you anything though.

There is a how to thread in the engine section.

I have a 70 318 with forged crank. I think the 1st year for 318's was late 67, but could be wrong.

 

[RAT ROD AL]

So can anyone tell what the crank and balancer is , ????

Mike , Cant find what you're talking about.

318's are neutral balanced whether it has a cast or forged crankshaft it would use a neutral balancer.

Like it would work on 273 and 340s

 

[Jadaharabi]

Pictures of the crank throws will tell if it is cast or forged.

Heres a link to help

Yes as long as it is internally balanced.

OK so it looks like it's a 76- 79 block, would these pistons and rods work with a steel crank motor? Balance would be OK ?

 

[4spdragtop]

From my knowledge, getting things balanced could prove pricey.
When I was going to do a 318, pistons are pricey. Machine shop quoted me around $600 to balance.
