These numbers seem closer but I have a question for anyone reading this thread.
According to the second set of numbers, the OP’s cam would be .125-.150 from coil bind. Isn’t that way to much clearance? I thought you aimed for .060 or so from coil bind.
Help me out, I’m trying to learn this stuff.
Again to the OP, nice build!
Thanks

Installed height is 1.800. Max lift with a hyd flat tappet cam is .580 (more starts getting too much pressure) Max lift with a hyd roller is .740 and coil bind is basically 1.000 so 1.800 less .740 leaves you with .060 before coil bind. You don't need to set springs to their max prior to coil bind, you need to set them for the cams ramps and the intended RPM range. BTW, we always recommend 1.65 rockers which would put him at .615 lift. Thanks
