NOT A CHANCE!!! LOLdetuned slug ~ yes, yes it is.. if you don't want it my number is 555-5150....
???I'd be more worried about that cylinder ridge...
Do you mean that wear that can be seen where the piston reached the top?I'd be more worried about that cylinder ridge...
First is pressure test, Then magnaflux, then sonic check the bores. Without doing those things you never know what you haveThat ridge is quite a bit of wear for a 340. The "de-tuned" 340 used the same block but with low comp pistons, cast crank and 1.88 intake valves. Take it to a machine shop and have them measure the bore to see where its at now. Judging by that ridge it will need to go at least +.010-.020. Have them check for taper as well.

Well I dug through the bin of parts for this motor and found the external balance, so I am learning!The only things they really changed were the compression ratio, went to a cast crank w/external balance, and 1.88 intake valves/hardened valve seats. Nothing that couldn't be addressed during a rebuild.

I have heard people comment that they are still really good motors!My best friend Rick, (RIP) ordered a new 1972 340 Duster, 3.23 SG, 4 speed. We took it to Dragway 42 early spring 1972 when it had about 5000 miles on it..
He only made one pass and it ran 14.51. That was pretty good for a totally stock 1972 car except for G70-14 Pokyglas tires on the rear. His mom had a Goodyear credit card, LOL.
My 1970 Swinger 340/3.55/4-gear, went 14.4 at a tic under 98, with 12,000 miles on the clock, on the E70-14 Polyglass tires it came with. It weighed 3330 with me in it. Daymn that car was light. Also 1-pass only.My best friend Rick, (RIP) ordered a new 1972 340 Duster, 3.23 SG, 4 speed. We took it to Dragway 42 early spring 1972 when it had about 5000 miles on it..

With all this talk about Ridge I decided to add some pics of the pistons to see what you all think?Exactly. Also sometimes the ridge "look" can be deceiving. Best to measure first. I've seen a few that were still in spec even after honing back round. It's rare but it happens.
