Can these be used on a 340? pros and cons? Steve, I wish I could be there to see your dads car. Make sure you treat Him to a few beers(out of Scotts cooler):D

Maybe, but mine has the VIN stamped there too.Nothing on the bellhousing flange.

VIN should be on the front, drivers side of the block, not at the back. That was later. Check the valley, and see if it has extra oil passages, with block-off caps on the head surface.(just out of curiosity)

Well, thats three we know of. They made it sound rare, but likely all early blocks were like this. I wonder if early 318's have them too? I can't remember seeing them before.

In the current issue of Mopar Collectors Guide, a gentleman stated that his 6-67 date coded 340 block has 4 oil passages in the valley, instead of two. Two of them are capped off. My 6-67 block is the same. I'm now very curious as to why they were cast in. I wonder if Mopar had other oiling...

Sounds interesting. These are closed chamber right? I would still unshroud the intakes as best as possible. I hope you get some good responses here. This is interesting.

AMEN!!!!!!!! A simple, "thanks Bud for the info, good job" would have sufficed guys, to help at least make chubsgts feal good about his post. Thanks for sharing chub

Regardless of how you proceed from here, I admire the time, and craftsmenship you have invested in this project. Anybody can unbox new heads and slap em on. I hope you complete the heads, and take pride in your accomplishment....well done :salute:

Thats not a spreadbore intake. I made the same mistake once. The 68-69 squarebores had slightly larger secondaries. Spreadbores are MUCH larger.

Yes, it is great for getting rid of skunks.

Corsairs were called "Whistling Death" by the Japanese, not P-38's.

360

Ya, I kind of thought it would be a no-brainer in any post(except a restoration 340 project) Maybe we should start a GM small block forum.....should we do a poll?

Yes!! That was YOU I saw!!! Where did you get the furry helmet Scott?...and why did it have training wheels? :poke:

I'm pretty sure that 302's are "closed chamber". They are not like the old 318 heads. Am I wrong?

The boy does know how to get a response though. (He's just used to 318's)

Great explanation moper. Duster, you should start a new thread to help with your cam. There is A lot of knowledge here, but they need a "cam" title in a thread to find it. I'd help, but I'm an idiot with cams.

We got the idea. It sounds great:cheers:

At 10 : 1 you really only need a set of good gaskets like the Fel-pro's, even at .060 over. The Cometic MLS gaskets are quite superior though.

About 270 hp would be my guess. More depending on the comp ratio. (how old are you now?) Welcome to the site.

Welcome aboard Howard. As stated by our esteemed colleague, 68-340.....:worthles:

I just read that last night! Any insight on how it worked out? You did a fantastic job.

The price is certainly attractive, but I too like to stay away from Chinese parts. I run a knock-off single plane( American made), that works really well. The only knock I have on this one is the dual bolt pattern. It just doesn't "look" right. If it does what you wanted, then you got a good deal.

Re-priming the oil pump wouldn't hurt either way.

Those caps are garbage. I opened my daughters up once to check the coolant level, and could never get it to seal again. I just bought a new cap, and no more worriessss.

I would agree with caferacerx. A good welder could get you back on the road by Wed. Probably cheaper than a new pan. My pan was sectioned, and three inches added for more sump depth. Never has leaked.(yes, it was TIG welded)

Don't be ssssilly Snake. Buy the new pan. J.B. is NOT the way to fix an oil pan. Shame on you guys for suggesting it. It might work, but this is the life blood of his new engine we are protecting. Maybe you could find a used one, but it sounds like you've already ordered a new one. Good decision.

Use lots of break in lube, gotta get things good and sssssslick.

Make sure you rotate clockwise, and protect the bushing(black tape, or grease) I turn the crank around by hand a couple of times like others have mentioned. I just read an article that said to open up the oil pump, and fill it with assembly lube also. Never done that, but it sounds like a good...

Jack, you lucky dog. Now you get to play around with your car some more.:cheers:
