Mark TDC and Add a Timing Pointer to Your LT1 

That "socket extension bar" method for TDC is pure ingenuity ! Going to apply it to my 283 tomorrow. Greetings from Finland!

Great video Karl

I'm glad I planted that seed lol. Thanks for the video!

Thanks for sharing. Recently went round and round on my cammed LT1 with this after replacing my guideplates. Kept chasing noise in the valve train that wasn’t there before. I used an inspection camera to verify where I was. Used a factory cam on the bench for reality check of base circle positions to differentiate between #1 firing and #6 firing. Still noisy. I’m chalking it up to the beaten/ worn 13 year old lifters (short travel Comp 875-16). Time for new lifters and pushrods I’ve decided. Been wanting a marked ATI damper for a while. Once you have TDC established you can mark any damper in the about 1:30 position and align the tab to it at 0 and call that your TDC mark, just like a traditional SBC Gen 1. You could put the tab at the bottom if you really wanted to, the tab for the timing light is just relative to itself as a reference once it’s set to 0 with the engine at TDC. The 1:30 position was chosen for visibility since it would otherwise be hidden by front accessories. Just works out to be a good spot to be able to see it and hit it with a timing light. But this exercise got me motivated to go after it pretty soon. Thanks!

Permanent tattooing timing marks, cool idea!

Nice!

1st commercial 1:15 into the video… awesome! 2nd commercial 6:10 in…..hopefully I can make it!

You need to produce you own for sale for other lt1 owners

Hi Karl, You found TDC on the damper then etched it. So to be clear when you bring the 0 mark you just made on the damper to the pointer and they are aligned number one piston is at true TDC. If one was to remove the cylinder head piston #1 would be flush with the deck. Is that correct? Probably answered my own question. Thank you.

Thank you

Thanks for the video. Can you tell me the part number for the Fluid Damper you have on that engine? Thank you, Dan

HELP-92 corvette LT1 with the 24x conversion like yours in the video. I'm running the holley terminator ecu and harness. The ECU puts 12 degrees into timing but it seems that the timing is wayyyyy off. I mean coughing out the intake after shutdown.... have you noticed the torqhead conversion timing being way off? Thanks

What size socket extention did u use? U never said if it was 1/4. 3/8 got an lt1 myself with an hei dizz and im having an issue getting TDC dead on.

What aftermarket aluminum heads and CAMSHAFT do I need for a 1995 chevy LT1 2ND GEN I HAVE A SPEEDMASTER 4 BOLT MAIN 350 STROKED SHORTBLOCK BUT I REALLY WAMT TO USE THE FACTORY INTAKE AND I HAVE A PAIR OF 76 MM TURBOS AS WEEL TO INSTALL. TGANK YOU

Do I need to remove the rockers to do the top dead center test

If my valves don’t go up and down when I rotate the crankshaft what does that mean
