I was thinking about going with Cutlers 800 kit for my M sled. Has anyone had any experience with the Cutlers kit or any other big bore kits for M sleds?

I just bought a full rolling chassis from the Racin Station.
M8 162" EFI, Speedwerx single/lightweight can, saves 10 lbs, and puts out 165 hp. Twin Pipes put out 174 hp but aren't recommeded for high elevation. Since it was an in-house motor I got the bottom end, and crank massaged also.

Call the different shops and ask a whole buch of questions. My main concern was what motor worked best at high elevation as most of the 800 bolt-ons were taken off the F-8 specs mostly run at lower elevations.
