Re: Inexpensive 350 Build
Some of you guys are missing the point of this build. Sometimes of run what you have in front of you approach can be fun. Who cares if it has thick rings, stellar machine work, a good combination, head work and whacking and cutting on the parts you have will still be impressive in the end.

Dart little m2 sbc oil restrictors
Just a double check. Old original Dart Little m sbc billet cap block I an using a .050” drilled 1/4” npt plug in all 4 corners of the lifter valley oil feed. Now the new Dart little m2 block if you plug the front of the left side lifter gallery it forces oil to the center crossover in the valley. Yo...

Re: LS Valve weight VS spring pressure
You need Ti valves and a solid lifter. It might be dependable with a solid lifter and stainless valves. You cant expect to control the valvetrain at 8000 with heavy valves and a hydraulic lifter. It wont follow the cam profile very well. 7000 rpm would be probably fine.

Re: Custom pistons or zero deck the block with off-the-shelf pistons?
If you are planning on 600 for a set of pistons, customs are not an option. pick a shelf piston that will work for you. .005” off the decks is not an option if decking correctly with a bhj. It will take more. choose a ready available.040” felpro head gasket, square deck the block for .005” in the ho...

Re: Do you HONE your k-lines, or just "broach" to size, OPINOINS please
From my experience, I broach the liner shooting for .001 undersize of the valve stem with whatever size ball you need, leave the k line actually stick up out of the top of the guide. It helps from allowing the seam of the liner to flip on top of the other. Trim it after all the honing with a Sunnen ...

383 stroker mill clearance dimensions
Years ago a guy i worked with had a cheat sheet to mill the pan rails and bottom of cylinders. Dimensions from the 5/8 dowel on the pan rail to each cylinder. Anyone on here have these dimensions to share? very simple way to do it.

Re: Opinions on max Bbc compression
for a regular customer, the max I would shoot for would normally be 9.5 to 1. My gut tells me for an every day street motor that you can keep in tune 10 to 1 would be what I would shoot for 10.25 to 1 max. But I want to see what others opinions are.

Re: Zero gap rings
I wouldn’t have used any of them in the past, especially the 2nd ring gap less. But i have seen a couple top tier sprint car engines with only the top gapless. I am a firm believer in a wide second gap to relieve pressure above the 2nd ring. 15-20 years ago i was told the gapless rings showed blowby...
