Hi All,
Is anyone running the Ford Racing Z460? Thinking of going this way but I can’t find much feedback on their track results. Are they any good?

lots of cubes, but could do with a set of TFS highports like the 225cc or 240cc sized CNCed ones and a custom cam plus some more compression,

It might be perfect for your needs. It has some good basic hard parts in an under stressed mild build that will make good tractable power. One thing I would have done differently on the bottom end would be good I beam rods in the slow winding high torque application. That said, those H beams will work well in that under stressed combination. I see it was tested with a Super Victor intake. I tend to think in that mild configuration a cleaned up Air Gap would be a good. Might be worth a little research. Let me ask, what is the overall goal? |

Thanks guys, when looking at this combo with low compression and low on the RPM scale I was thinking it seemed a bit soft, the question is this due to the block being maxed out because of the cubes? I’m looking for a good strip engine that is still drivable. 600hp at the tyres would be nice with a heap of TQ. The price on these seems good and being a bit soft I thought would be good for reliability. 150 shot of NOS and I’d be close to target. I’d appreciate some build combination ideas for around the 20k mark.

Interesting. I’ve been considering the same motor for my ‘77 F100 to replace the tired Cleveland. I figured all that torque would be useful and as everything is new, it might be better than machining my aging block, assuming it can be reused.

Nice match for the F100 👍

I wouldn't go a pony over 150 shot with that block though. According to Ford the block is designed for a minimum cylinder thickness of .180" my old limit was .170" for 700hp in these kind of blocks. Of course, where that thin spot is makes a lot of difference. Is it at 3:00 and/or 9:00? or also 12:00 and 6:00? Side to side, no big deal. Thrust side, don't go over that 150 shot. In all honesty we took this approach with a Top Sportsman car. We got 3 of the original 600cid Ford crate motors and threw away the rods, pistons, dampers, cams timing set,. Did a little work on the old original A460 heads and bingo had 3 rotating motors. 1 in the car, 1 spare in the hauler and one getting a freshen up. Qualified every time and was usually in the top 4. Based on what your expectations are, I am going to recommend using what you found. I could work something up for you, but it will take longer to get and you will have to track more details on your end. |

I'd assume it's probably to make them reliable and keep the cost down, while providing a fairly smooth idle and reasonable fuel economy, while being able to run on lower quality fuels. |
