I must slightly correct this ...... ring gaps should NEVER be on the thrust side of the piston. When the piston "rocks" in the bore under combustion pressure, it's possible to dig a ring corner into the cylinder wall. I like to place the compression rings 180 degrees apart, halfway between the pin and the thrust side of the slug. Nit picky? Yeah .... but I can't help it! Comes with the territory, I s'pose
What deck height did you end up with ...... I'm curious. I'm GUESSING about .015" down in the hole? A stocker is around .040". We don't any of those compressions to get out, you know!
@GHG...man you guys are geniuses.....you make it look easy.....
Ah. Thanks!ScooterBob, you're answering posts faster than I can read them!As in, the ring gaps should line up with the pin, rather than be 90° off?
I'll see if I can get you a better pic of what he means. In the mean time.....http://image.musclemustangfastfords.com/f/tech/9169875/mmfp_0711_05_z%2Bford_small_block_stroker_engine_build%2Brod_angularity_and_piston_side_thrust.jpg
Closing my one good eye and squinting.... Yeah, that looks about right Cuz.
@GHG:Looks very impressive. You and SB are making this Racer better and better . I hope you can ride it sometime before we get snow storms and noreasters, that we get every winter. It will be hard to wait till spring to take it out for a spin !
That's how I checked the gap on my last set of piston rings. It looked like 0.2mm. Scott
Of COURSE we are geniuses ..... We are Celtic - we can't help it! BWAH-HA-HA-HA-HA!! ..... and it IS easy. All you have to do is sit in the shed for hours on end with a little Glenn Miller on the radio and a little sippin' elixir in the 12oz. tumbler and drill, tap and grind until your heart's content. What could be easier than THAT?
Ah - gotcha. I imagine you'd get the most side thrust during the power stroke, but also perhaps some on the opposite side of the piston during compression? Even though the piston is traveling in different directions, there's still a "downward"(i.e. away from the head) force during each phase...
+1 on the mag pickup tools!Finally read through this thread, and OMG this is cool! Love what you two have done so far, and I'll be paying more attention. Great logic and carry-through on the rockers BTW!
Thanks GHG! As for the magnet, I guess we don't have to ask how you learned about that trick... probably a long time ago!
There is NO gasket on it.... just goop. I should make one, now that I think of it ?
..who wants to reseal that cover if you don't have to.
That was a Long read !
Well you could, but...
yes it was, but once I started I couldn't stop!
