Try to stay with an intake that has 318 sized ports but the factory put large port 360 4bbl intake manifolds on the 318 when they finally went to a 4bbl and they still worked great. 273 4 bbl intake is a good match too. All the 340 other goodies work on 318 such as double roller timing sets, 340 camshaft and windage tray.

Just opened my 69 service manual and it says 2.4995"-2.5005" and your conrods are like you said 2.124"-2.125". Hope this helps

The pistons and crank where not made together as an assembly. Using a new crank means a RE-balance. His new crank would have been balanced to a stock piston weight from the factory. The assembly has to be rebalanced for sure,and knowing what the factory balanced each years 273318340engines to helps if you have a choice.

The one that I owned had a 318 with a holley 4 barrel, headers, 4 speed with a hurst shifter and a few other extras, seemed to have plenty of horse power to me. The car that I just got has a running 318 in it but also has a 340 block with crank and piston rods. I know that the 340 is a very reputable engine but its stamp date is 72.

A 340 has heavier rods and pistons than a 318 so it is balanced different even though it is neutral balanced. It is a 340 crank shaft in a 318 with all 318 rods and pistons. However they all spent time in an engine builder's shop together and he did his magic to make sure they would all work together. I thought the harmonic balancer off the …

340s with a forged crank were internally balanced, 340s with a cast crank were externally balanced. (made as running change during 1972 model year). All 340 motors used HD rods. The 318 from 67 on used a cast crank and the motors were internally balanced using non-HD rods. Easy ID for cast crank is a ¼" wide casting mark in non …

Now, if you wanted the 340 4.040 bore in a 3.91 bore 318, with the 318 crank and the 318 block, you could have the block re-sleeved that large (4.040 for 340). Cost-wise it would probably work out to about the same cost, maybe even a little less, after main bearing inserts, the rear bearing to pan has a smaller diameter so the block would …

The Chrysler 340 V8 is from the Chrysler LA-series of engines, which Chrysler bored out from the 318. The 340 uses a cast iron block and heads, and has a bore and stroke of 4.04 inches x 3.31 inches. ... From 1972 on, Chrysler changed the crank to cast iron to reduce costs. The pistons were cast aluminum and flat-topped with valve …

The 318 and 340 cranks are dimentionally the same. When properly balanced to everything, they should be interchangable. Both used cast and forged cranks. I had a 318 forged crand out of a 68 Fargo 1/2 ton. Comparing it to my 340 forged crank-the 340 crank was "lightened" due to the fact the 340's used a heavier rod. # 3. 10-01-2002, 01:32 AM.

Dec 19, 2010. #1. I just bought a 1974 rebuilt 318 and was wondering how can you tell if it is a steel crank or not.It looks to me to have the thinner balancer on it which makes me think its a steel crank engine.I had a 73 340 years ago that had the wider balancer on it .So I always assumed the 340 was a cast crank motor.I know the general rule ...

Location. Littleton, CO. May 24, 2010. #2. Kieth Black, or icon as they are now called, has pistons for the 4" stroke 318. Eagle will tell you what bob weight they recommend if you ask thier tech people. I believe it comes out to be 390 cubes, and it should up the torque output quite a bit.

If youre going to use the 318 crank then you want to use the high compression 318 pistons. 360 crank/318 block = low compression pistons. 318 crank/318 block = high compression pistons. Also remember there will be some balancing costs involved in putting the 360 crank in the 318 block. But in the end it makes a decent, …

318-340 are internally balanced, 360 is externally balanced. Therefore you can not swap vibration damper, flywheel, or torque converters between them. 360 uses larger bearings and crankshaft journals. 360 has one motor mount in different location (as the other poster mentioned). 340-360 heads have larger ports and valves than 318.

That early 273 crank has a smaller hole for the crank snout to fit into than later model engines had ('67 & later I think). So a converter used behind a 318, 340, 360 and later year 273's will not fit. Machining the hole larger in the back of the crank while it's at the machine shop for balancing is one option.

You can narrow it down some by looking at the vibration damper down on the crank. A 318 will always have the thin zero balanced damper, and the 360 will always have the thicker offset balanced damper. ... Big arm means a bigger crank stroke.JFYI 340=3.31 360=3.58 408,416=4.00 inch crank

2,859. Location. Augusta, GA. Apr 14, 2009. #1. When I took off the timing cover from my 318 there was a flat, circular blade-type thing on the crank in front of the crank timing chain sprocket. Now I'm putting the engine back together and it seems like from what I'm reading I don't really need that oil slinger thing.
