I run 273 adj. rockers on my 340 with the 508" lift purple shaft cam. I am using crane cam adjusters on them with jamb nuts. My block has been milled for zero deck height and the heads have been milled slightly, I measured and used custom push rods from these guys: oepushrods.com

Wix or Napa Gold (re-branded wix) for me!

The mount in primer at the top LH is a driver's side 318, the black mount next to it is a driver's side 340. The bottom mount in primer is a passenger side 318/340. All for 67-72 A body

If the lifters aren't labeled, just toss them and buy a new set.

I run the 51085 on my 340 with full length tti's and no adapter

Thanks! It's just a '69 340 block .030" over with KB 243 pistons at zero deck height. Stock forged crank and rods all balanced. 2.02 valve #915 casting U heads with light porting. Old school MP purple shaft 292 duration .508" lift cam with 273 adjustable rockers. Edelbrock Victor 340 intake...

My 340 on the stand before installing in my 72 Demon.

Yes they are 1/4, I always just use grade 8 bolts from the hardware store with lock washers. I believe they are about 3/4" long.

I agree a push rod length tool should be used to determine proper length before ordering. They can be purchased for around $20.

I called them on a Friday afternoon and placed my order, they made them and shipped them out Monday.

I also found this out the hard way too, I needed push rods that were 7.250" from the ball to the top of the cup. So I ended up having a custom set made from a company called OE Push Rods, was around $65 shipped to my door.

I got them all set and everything looks good.

This is my first time using adjustable rockers. I have 273 factory adjustable rockers on a 340 with a MP .508" hydraulic cam. The first thing I did was replace the original adjusters on the rocker arms with crane cam ones with a jam nut. Next I ordered a push rod length checker. With the...

I have always put some RTV around both sides of the coolant ports, and used the cork ends also with RTV on both ends and never had any leaks.

I would definitely pick them up for $200

I would inspect the main/rod bearings, pull the heads and check out the cylinders. If everything looks decent I would just re gasket it and put it back together.

I used stock 340 valve springs, and in my 318 it had a noticeable idle with flowmaster 40 series mufflers.

I ran the .441" lift Summit cam in a mild 318, engine also had milled 360 heads, edelbrock performer intake, and headers. I was very impressed with the performance, it pulled strong to 5,500 RPM.

I believe the machine shop gave it a Acid bath, the rust in the cylinders had no pitting at all. All of the rust was just like powder.

Heres a std. bore 340 block that I picked up last winter for $100. Believe it or not this thing cleaned up like new and doesn't even need bored. Sorry I don't have a after pic.

Maybe give this a try: http://www.massmopar.com/Files/340save/photos/photo1.html

It will be a cast crank, but it should have bushed connecting rods.

I have run the .441"/.441" Summit cam in a mild 318 in a '72 Dart with good results. I also had headers, Edelbrock performer intake & 600 cfm carb. The little 7 1/4 rear didn't like it very mutch though even with a 904.

I have a real nice 340 block that I am going to be building and it has TRW L2316F pistons. But the problem is I lost one of the pistons and now only have 7. The TRW pistons are now Speed Pro ZL2316F. Are these the same pistons? The 7 pistons I have are in excellent shape, and have very low...

I have used Percy's seal 4 good with excellent results.

J-heads are a 360 #915 casting head and came on 360's with 1.88 intakes valves and were used on some 340's with 2.02 valves.

I have the .441"/.441" Summit cam in my 318 and it runs good (pulls strong to 5,000 RPM) but I think im gonna swap it out for a Comp XE268.
