Why isn't someone reproducing 340 blocks ? It's just stupid not to do it . Help me with this please .
Careful with believing this blindly since the 340 bore is a 4.04 and the 360 is at a flat 4 inch doesn’t automatically mean the 360 can take a .040 boring.You mean because of the difficulty of finding a good used one.
Some guys have bored 318s out to 340 size
You can bore a 360 out to 340 size.
If you really want a 340 put up a want-ad. If you can't find one Pm me; I have several you can chose from.

And that’s what the Ritter block is for though it is a racing block.....Because everyone wants a thousand DIFFERENT blocks! No manufacture will attempt that. Let's settle on one size and work around that.
I seen this ([FOR SALE] - 340 shortblock)I've had a standard bore, absolutely cherry 340 block on the classifieds here for sale for a while. It's not like you can't find them if you look.
How much does a 340 block go for nowdays,or a shortblock? Lets say ,030 over .Any idea.
Oh, I'm sure it has been done. Too many experiments have been done out there with this stuff to not have been done LOL. Seems like I read about it here some time ago...AND Don’t believe anyone that says there 318 went to a 340 bore unless you can see and measure it YOURSELF! Because it is more than likely a bunch of horse **** served to you on a silver platter.

Last time I shopped for 340 block, they were going for around $400-600 typically in the mid-Atlantic region. That was 2-3 years ago.
Easy to understand why to not to make 340 blocks. The real cost of starting production is 10's of thousands of $$$$$... both in time invested and tooling. Not anywhere near worth the risk for such a small market segment. It's not a wise place to invest one's time and $$, when you can take the same investment and make a lot more $$$ on a Chevy or Ford or even a SBM 360/5.9 part and with low risk. It's dumb TO do it. (FWIW, I've run my own business for 15 years....)
I have personally laid my eyes on ONE 68 vintage 318 block that was bored to 4.040, it was a dirt track engine from many years agoI know a place that takes them 318’s to a 4 inch bore if they pass the sonic check.
I have read that it has been done before.
But until I measure it myself.......
Seriously, a .130 overbite? Maybe. Depends on the sleeve used.
Cool! You just never know what folks will try LOLI have personally laid my eyes on ONE 68 vintage 318 block that was bored to 4.040, it was a dirt track engine from many years ago

And thought about taking a extended vacation to test out my new trucks abilities.....
Very tempting sir! Very!
The above is accurate in general. If he were here, it is possible to get $50 - $100 more due to my odd location and high scrap rates/overturn on metal. There are no places like pick anoart or anything more than a few years old. Prices for junk yard engines rival new rebuilt prices.
The last oval track engine I did for a guy, we used a magnum block, just plate honed it .010 and put custom pistons in it, to keep walls thicknessOh yea! I’d be looking at a race block for big bore builds.
The one I saw, blew up, and I'm a big fan of thick cylinder walls, not max bored thin ones
