427 Tall Deck MarkIV block, casting number 473478 which is 1977-1990, 4bolt main. These make great stroker blocks, as you can fit a 4.25 crank, and make 496 easy (without the overbore). With mild grinding (if any is needed at all) you can fit a 4.5 crank, or a 4.75 if you want (definite grinding though). It's fresh out of the machine shop, new cam bearings, .030 over.
I also have a set of 781 heads (casting 336781) open chamber, and a Holley Strip Dominator intake, all ported and polished (I have intake spacers for manifold as it's a "normal" bbc manifold). The heads do need valves and springs still. They were cut for 2.19 intakes and 1.88 exhausts.
Also, a hydraulic roller cam, custom ground, cam specs are: 288/296 advertised, 225/233@ .050" , 595/615 lift, 112 LC
Will take $800 obo for everything......or open to full/partial trades for man things. PM if interested...
