Anyone really need this particular motor or want to trade for a slightly worked up 360?
Ok this is a strange one and I'm not sure where to post this but here it goes. I bought a running 340 for my Duster a while back and tore it down figuring I'd check it out and put back together an run but found some issues.I'm at the point where I'd rather spend money on getting the body and paint squared away on the car so I planned on putting this on the back burner till the car is done, but dont know when I'd get to it. So I figured before I do that, I'd see if there was anyone who really needed a serious 70 340 to build for there car. Heres the story...
It looks like it was a full on race motor, it is a .030 over 340 with 12.5:1 TRW forged pistons, forged standard crank with studded mains, external oil system, and hd smothed rods. It had J heads with longer than stock 2.05/1.60 stainless Manley( I think) valves, W2 style rocker setup( for the longer valves, double springs with damper with titainium keepers, positive seals, and had a full port and polish. It was ported into the valve cover bolt holes, which I heard was an old racer trick to open it to the max and the use of sealed valve cover studs would work fine. It also has a windage tray and a valley pan baffle,adjustable rockers (273's I believe) and a ported Edelbrock single plane intake.
The guy I bought it from recently got it in an old Barracuda and pulled it out in favor of a 383 and had no idea what it was. So much in fact that the little he drove it, he ran regular gas and when I tore it down I found a couple pistons that had melted at the deep valve recesses. The bores look pretty good with crosshatching still showing but there is a tiny bit of ware from the skirts on the bottom of the bores. Also looks like the crank could use to be polished or cut to be perfect.
My plan was just to hone it and drop in some pistons. I actually bought a set of the exact same pistons used and had them cut down to yeild a 10.5:1 compression with the 62cc heads(yes, I cc'ed them). So you could either use the pistons I have, hone, cut or polish the crank, reballance and reassemble.The heads look great but of corse I'd have a fresh valve job done.
The block is stamped 7-2-70 and 2780930-340-5 and the ID pad is
1B193352 . I would love to find someone thats looking to replace a non correct worked 360 in there car ( something I can just drop in my Duster)and trade for this setup but would take offers is anyones interested, but I know what I have and have no problems keeping it to build into a monster 340 when the time comes so please, no low ballers. I have a ton of pictures if anyones interested. If no interest then I'll pack it away for a later date, but I figured I'd trow it out there, maybe someones looking for a correct 340 for there build. Heres some pictures. ITs in Hazlet, NJ.
