Stroke it....! and it will grow in size.

How much will you have to take off to get them to zero? You have to factor in pushrod length once this is done. Having to buy new custom length pushrods might be false economy over getting the right piston. Also port alignment on inlet manifold would be affected. If using open chamber heads, zero deck means nothing. You only do it with closed chamber heads to tighten up the quench area and give better turbulence. Sent from my CPH1903 using Tapatalk

Depends on what you're using it for, but just remember CFM = HP. So if you've got a stump-puller that peaks torque at 2500 and makes around 300hp but runs out of puff before 5000, a 600 would suffice. But if you go putting 4V heads on, roller cam, single plane manifold and spin it to 6500+ then a 850 or bigger is in order. I would love to have a play with one of these and shove it in a box Falcon as a torque monster with nice tall gearing. I'd really love to feel the torque in a relatively light body just effortlessly surging along without even breaking a sweat. Sent from my CPH1903 using Tapatalk

Shorter belts are available. If you buy a 'standard style' serpentine belt, it's number is something like 6PK2375, or 4PK0985. 6PK has 6 grooves, 4PK has 4. 2375 is the length in Millimetres if you cut the belt and lay it flat on the ground. Dont forget to add/subtract some extra for the tensioner pulley. Old Vee belts are the same.... 11A0875, or 13A1195. Groove size x Length.

that split is standard for an au 5.0 power steering pump

Is the XF power steering lines long enough? I’d like an AU 5.0 in my XF Ghia as it would be a nice cruiser, but can’t really bring myself to take the original xflow out. Sent from my iPhone using Tapatalk

If you got the 400 at .030 over and chucked a cheap set of valve-relief pistons in it (assuming 8cc dish equivalent) the thing would be about 11.3 to 1 compression if you used 302C closed chamber heads.

Its my work in progress still. I have had a change in direction with the back. I built a box but I am going to remove it and make 2 side boxes

One thing you could do I guess, if pistons are too pricey or hard to get, is to bush down the standard rod little ends to suit 351C size. 351C: 0.912" 351M/400: 0.975" So that's a difference of 0.063", or 0.0315" wall thickness in the little end bush. If that's within the capabilities of your machine shop, then it might be an avenue to pursue. That way, not only could you go with clevo pistons, but also full floating at the same time.

+30 will make it 408, isn't that enough? The stroke is already 4", longer than any Ford big block ever made. Only some rare 1970 blocks were made with the smallblock bellhousing pattern, all others were big block, as is likely for this one. Maybe a big-block C6 is worth something out here? I dunno.

Im glad you said that cause thats what i told the engine shop and they said nahhh Sent from my SM-G570Y using Tapatalk
