Casting number C2AE6015C. According to the y-block info on the net it could be a 312 but I can't see the rear of the crank, to see if there is an asprin size dot on it. It's on an engine stand and has the flex plate attached. Most likely it's not a 312 but either way I will probably use it.
I have a 460 in my daily driver, Early Scout. My Scout should weigh about the same as a early F100. I rebuilt it with a small performance cam and mild port cleanup, I installed it along with a factory Ford ZF 5 speed truck trans. It runs great & mileage is 16 MPG in town and much better on the highway. I run a 340 gear and a tall tire, I can cruse at 80 all day in overdrive. No 2bbl will ever get as good of mileage as a small 4bbl. The 289 and the Yblock are neat motors but not the best if you are really going to drive it a lot. If you want a small V8, get a late roller cam 302(5.0) and a overdrive trans. A better choice is the 351 W.
What size Y block? Either way its bad just go ahead and give it to me lol. Do the Y block keep the truck Vintage and more importantly F O R D!
First, ignore the brainwashed rah-rah Chebbie strokes. I'd also use the Y-block, they have the cool factor and are tough as nails- the only real problem was the oil clogging thing, and regular oil changes and good detergent oil makes that problem bupkus. In the old days, the demoderby guys around here used to seek out all the Y-blocks thay could find, as they were the V8 that would run the longest without water after the radiator got tagged. We used to have an old '59 F250 work truck with a 292/ granny 4spd, and we pulled our asphalt paver on a trailer with it all up and over the hills around Napa for years- change the oil regularly and put some points in it once in a while, touch the key and it was running, bubububububub out the big dual truck mufflers- just sounded sweet My stepdad later bought a 3/4 ton General Messa Crap with a 350 Chebbie and granny box to replace it, and we'd have to hook onto the front of that one to make it up the hills, even with the 4.10's
