I do...

just posted another engine I have

I can't find the meaning of this number, "0064". It seems not all 340's have a number mark here? tia

I just picked up a bare 340 block date 5-28-69 partial vin 0B165764 Anyone looking for it? If not, its in line for my next build. EDIT: I have another vin I can put on here... date 6-20-67 vin 8E134941

It looks like a forged steel crank to me, am I right though?

I have a feeling previous owner built a stock lower end for a blower or possibly a stock motor with lower compression something.Ugh. I want no blower, just a well breathing na motor. It looks like pistons/rods need changed, I want forged. Do any of the crank stamps ID what it is?

Aloha! I'm trying to ID pistons and crank on a mystery 340 motor I bought. The pistons are flattop w/ 4 valve relief. It came with a lower blower intake manifold, so I'm guessing this engine was built for lower compression? I'm still learning, so any help would be greatly appreciated. Mahalo -N

Awesome thanks! I like the look/sound of those FHR's. Will the pistons I pull out be worth passing on?

Yes! Sorry, I meant to scroll up to look at your name to give you credit. I'm probably going to rebuild it with forged components and get rid of the blower. Wouldn't an 871 chew up these cheaper pistons?

Just throwing the rock back! The 340 was built with a blower setup, so I'm guessing they are low compression pistons. They do seem like stock low compression pistons the more I look online. Like I said prior, hopefully I can find some time to crack open further and get the full answer. Work...

I'll post what I find when I crack deeper. I'm hoping sooooon!!!

Hi Kim, Im still here, don't be a douche, eh? I work a hectic work schedule, no need to hate. It's a 340 that I got from an auction with no details on what's in it. I'm pulling it apart to ID everything in it before cranking it over so I know what I got. Sometimes I get excited about getting...

I’m slowly taking this motor apart to see what’s in it. I’m crazy busy so usually late night can’t sleep is the only time I’ve had to wrench. As it sits, what can any guru’s tell me about this piston? Looks like .030 w valve reliefs....but anything else?

Its settled, I shall crack her open!!! I'll post what I fond out this weekend! Thanks for all the great replies!!!

So what's the best way to determine the cc space above tdc...measuring everything or using the fluid method?
