I was wondering whether the factory pushrods had ball (welded ball?) or formed tips. Is there any functional difference? I seem to have a mixture of both which I will resolve as they are slightly different in length. Also, I am getting 0.090" preload. I assume this isn't a problem based on...

The teething pains continue but I think I have found the cause of a few tuning issues...low vacuum, idle speeds up when hot and idle AFR I can't be leaned out. I came to the conclusion that I might have an internal intake leak after not finding anything externally. I couldn't find too many...

I've got the Oregon 2120 version which is copied from an original cam. I was wondering what you are getting for idle and cruise vacuum?

It isn't talked about much...not sure why. Perhaps its just a small gain? I put nail head valves in my 340 to decrease the chamber volume. I did this instead of massively cutting the heads. I believe it was nearly 3 cc. The valves need replacing anyway and I believe they used Chevy valves...

Does anybody recognize this breather? It was on a '72 340 air cleaner but I don't recognize it.

I'm going through the brand new front end before I finally get this car on the road ('70 340 swinger - mostly stock). I found that the center drag link hits the oil pan on the driver's side and also rubs the TTI manifold downpipe. Fortunately I did find a set of Schumacher mounts awhile back...

Has anybody verified what type of aftermarket spray paint matches reasonably well other than buying the specialty paint from Mopar shops (would probably cost over $100 to get it up here)? My air filter housing has been blasted so I can't check it against other colors. So far this is my take...

I'm considering converting my '72 air cleaner to a '70. Anybody got measurements of the opening? I think its around 1 3/4 x 4 with a 1/4 radius.

I have what I think is a '69 and a '72 340 air cleaner and they both have 340 stickers on them. Would these be factory stickers? I'm not clear on whether some years came with stickers and some with plates. It seems the '70 340 air cleaner (elusive and expensive!) had a pie plate.

I have a '69 air cleaner that I was planning on painting with VHT wrinkle black and putting a pie plate on (hope it fits). Will this look drastically wrong? I think the 69 air cleaner is smaller in diameter and taller but I don't know.

I couldn't save my stock 340 pan so I bought the Milodon #30750 pan which says it takes the stock oil pickup tube or the Milodon stock replacement pickup. I had already bought a Mopar Performance stock oil pickup tube so that is what I installed. The problem is that the oil pan baffle hits the...

I'm considering running my soon to be rebuilt 340 on a test stand before I install it in my Swinger which is under restoration. I've built a test stand for an air cooled engine which was a lot simpler and cheaper. I don't want to be working on the engine after its installed should any issues...

I'm building a stock 340 and have this Offy manifold. Is it worth trying? Its an odd thing. - 68 4 speed cam - hp manifolds - real 10:1 compression - 2.02 'O' heads - 4 speed - street use only - carb - probably AVS2 650

I'm just disassembling my 1970 340 and find that it has 1267 pistons 0.040" over and the bores look good so far (thank goodness). I've got O heads. From what I see in I should get around 9:1 compression assuming the heads around 72cc. I have the equipment to cc them which I will once...
