Most likely goofing off... I'm sure he's making out his Christmas list to include Texas Roadhouse gift certificates, so he can pay up on yet another dinner bet, in 2023.

Picked up the block on Friday. Have only installed the crankshaft, and one piston. Need to cut the pistons down .005 or buy different head gaskets. Cutting the piston will be faster. How close are they to the head?

How close are they to the head? The piston was .011 above the deck, before this last mess. I have .051 Cometic gaskets. The piston now sits .014 above the deck. Too tight for my liking at this point.

Now don't go dragging my good name into this plebian world of wedgery. Isn't a Buick a wedge?

I am counting on block growth as it warms to increase clearance the head. If we gain . 008 in clearance as it warms. All good. I am thinking I should do a test to make sure. Now to figure out how to heat the lock to about 160,' to find out for certain.

I'd like to think the clearance would be fine with an Aluminum block, but I just am not willing to take any chances at this point. This engine has been 2 years plus in the making. No need to risk it.

Now to figure out how to heat the lock to about 160,' to find out for certain. I have seen some guys use a propane burner on a large pot of water that circulates water with the electric water pump. That was on an assembled engine though. I thought it was a pretty genius way to heat cycle and retorque stuff with the engine out of the car. Especially on the combo I saw it on, a twin turbo BBC that looked like a nuclear reactor under the hood with all the plumbing lol.

What are you shooting for clearance wise Jeff? Mine are .004 below the deck.... I want .040 piston to head clearance.

.040" piston to head with an aluminum block is plenty conservative......

.040" piston to head with an aluminum block is plenty conservative...... Right now I'm around .035-.036. The piston has plenty of rock in it. The highest point I saw was .028 above the deck.

Since piston contact happens due to piston rock, (those with more experience chime in if I am missing something) the idea of shaving . 005 off at an angle on the closed side of the chamber might be a way to save a current combo? The angle could be measured with the piston cold in the block, and the actual cut may only extend three quarters of an inch in. JUST THINKEN, 🧐

Fairly easy to just skim .005 off the top. Can I get away with less, while using an aluminum block? Probably, but since this is a bracket engine, and I really don't have the funds to be buying new pistons, once something does go wrong. I'll just adjust the old shoe polish on the window instead.
