Many years ago I got a 803 (75mm) big bore kit for my 93 600 from Franx machine worx out of IL I believe. I was living in HI at the time so I'm not 100% sure on the location and spelling. What I need is 1 sleeve from this kit and I don't know where to get it from. I don't know who made the pistons or the sleeves. It is slightly smaller than the 907 sleeve so I would have to get all four of those instead of the 1 that I need. Any ideas where I can find this sleeve or does anyone know if franx machine works is still around?

APE can make them as well.

Both of those #'s have been disconected and I don't think APE has the sleeve. The closest one has a slightly too large outer diameter. Thanks though

Like I said..... they can MAKE one. It may not be an off the shelf stock item but if you tell them what you have they can go out to the shop and crank one out to your specs. Atleast thats what it says in their catalog.

I bet it's spendy, too. Oh well; either that, or you've got 3/4 of a bore kit.

Yeah there are a few out there and it makes 120 HP with 36mm flatslides. I think I'm just going to put my stock 750 engine back together and pound the piss out of it.

I did a bad thing. I was thinking about the 1100 jugs. It can be bored to 77mm which is what I need. Does anyone know how much higher the deck height is compared to the 750?

Well after searching through tons of threads the best answer I have to my deck height question is about 10mm difference. Sounds twice as much as what I was expecting. I guess I'm going to try and get someone to mill down and bore a 1100 block. That should be cheaper than $600 in sleeves and labor unless anyone knows where I can get a better deal.

Is it normal for me to be talking to myself in here?

Sadly, Frank passed away over a year ago. He was a great friend!
