Mopar 340 engine build . Episode 1. "By The Numbers" 

Yes I am going to try and see if I can ring it with what cylinder wear is there. I ultimately would like a stock or as close to stock 340 as I can get. I have one that is .030 over also. Thanks for watching!

Thank you, I agree. Thanks for watching, not everyone watches this type of content heavily.

Thanks!

Thats what I am thinking. I have one already together,but it has flat top Pistons in it a bit lower compression. I am wanting to build this one as close to stock as possible with a 69 manual trans cam grind or close. Basically a street engine.

I agree. There is also the internal vs external balance etc. I like a 340 because it swaps with a 318. The flywheel etc basically interchangeable there is a difference in motor mounts but thats about it I have a 318 also thats sitting in storage. Alot of guys are building 318s now. I remember when people were giving them away. 340 was always worth something though noone giving those away...

Could even be the best small block anyone built

Yeah its a "rare" engine really. I am trying to build this one as close to stock with exception of the cam, with that I may stay " in the window" of stock 68 manual specs.

Yes,its cleaning up pretty good. I have sent the crank out for regrind and dug the heads out of storage. Depending on what the machine shop charges I may have the block freshened up ,new expansion plugs and cam bearings. I'd like to not bore it over if possible save it for the next guy :)

You'll want to run the early pistons for the compression ratio, approximately 10:1, the later pistons were 8.5:1. I think that was late 71 when the low compression 340 pistons came out. They are flat top with 4 vale reliefs. The J heads will be good either with the 2.02 or 1.88 valves. They flow good, big ports cast in etc. The cam will be up to you as in what do you want to do with the engine,is it a drag car or a cruise night car. I tend to stay in the "street" class of things, I like a nice cruiser. If I could, I'd run the stock 68 manual trans cam from MOPAR, and I am unaware if a reissue exists. I run the Summit classic series cam , its very affordable. Part number SUM-6901.

@@MrSwinger1 thanks for that I will look into it. I have a factory 340 four barrel cast manifold I want to put on it too, and I want it to sound lumpy and have good street performance, possibly 350 to 400hp

There is one on Amazon by Don Taylor. The book in the video is old, and possibly dis continued. You might find it on e bay used. The one by Dion Taylor appears to be the current version of the book.
