Hey, I've decided,forced to, to replace my old 460 with a newer motor, (rod thro block issues)..Anyways found a motor on ebay that is near me and have looked at it. The casting numbers are d1ve 6015 aa.. it is now stroked to a 460 he says. What I want to know would this be a good option to go with(Being a converter 429?) and is it really a scj block? does it sound like a decent engine or something not worth putting in my mud truck?
Thanks!!

Sounds like it is a 71 model 429. all you have to do to make it a 460 is pistons and crank. the rods are the same. i have had several. I do not build 429s because it cost the same for 30 cu in more, all you need is the crank. you will need new pistons which ever way you go.it should be a good reliable motor. I went 9.30s in the 1/8 with one in a 6500 lb van. used it to pull my race car.
the paperwork i got with my 429 a few weeks ago says, the D1VE AA blocks were produced in the michigan flatrock foundry from 1971 to 1978. the D1VE AA blocks have a narrower oil pan rail. the DOVE-A blocks produced in the dearborn factory were the only blocks cast with the extra thick main cap webbing allowing for 4 bolt main caps. the DOVE blocks were the CJ and SCJ blocks. it also says they tested 30 different 429 blocks with various casting numbers for ultra sonic thickness, and no block was superior to the other in cylinder wall thickness, the only difference was for the 4 bolt main cap. unless you are throwing over 500 horses into it it is a good buy.
Not a thick-webbed SCJ block, but is actually a standard 429/460 block, judging by the casting number and the pictures in the auction.Quote:

429's and 460's are identical down to every nut, bolt and part, with the only exceptions being that the crankshaft and the pistons are engine-specific (but even the connecting rods are the same). So it's no big deal that the engine was coverted from 429 to 460.
