My 1968 Chevy Van has one of those inline 6 250 engines. Great motor!

Hey fiatnutz, I'm wondering if you would happen to know what the total timing would be on a 1968 Nova L6 (250), Manual or any other info on timing these motors at all would be greatly appreciated. ..

Also I was curious to know if timing degree specs change when you upgrade from points to HEI? Meaning, if I were to use a 1980 HEI on a 1968 points motor, should I go with the timing specs on the 1980 or stick with the 1968 specs? Thanks in advance I watch you all the time. Angelo Chicago IL.

I noticed in your post that you mentioned using a 194 head. Is there something unique about that particular head?

[fiatnutz]

@dbenny1000 - The 194 head has a smaller combustion chamber.

[CoolasIce2]

I hope when you plan to do the machining on the head you show how you level it on the resurfacer, OR I'M GONNA UNSUBSCRIBE. I'M SERIOUS. .)

[CoolasIce2]

@fiatnutz No. Not yet.

@fiatnutz How much thermal cleaning costs? it really does a great job!

[MohdRidhwan]

Good stuff as usual. I'll definitely want to meet you someday but Im half way across the world.

[fiatnutz]

@MohdRidhwan - Thank you, my door is always open.

[VMATT500C]

GOOD point. I was thinking along the lines of modest size turbo ,intercooler, the ability to burn regular gas. Then maybe an electronic fuel ignition controller for water alcohol injection for passing plus a little nox bottle for fun.

[steamsoldier]

Once again great video, thank you for posting!

[VMATT500C]

Low Comp. pistons & a Turbo wold be Nice.

[fiatnutz]

@VMATT500C - Why would you want low compression with a turbo? I run a minimum of 9:1, up to 10.2:1, and use less pressure to do the same amount of HP. Compressing air just makes it hotter and you need an intercooler. Plus, off corner acceleration is better because the you don't have to wait for the turbo to make spool up.

[flyboy333]

@fiatnutz I read in a fairly reputable magazine (SCC or GRM) that low compression just makes a turbo motor much easier to tune, even though the higher velocity gas out of a higher comp. does indeed spool the turbo faster. It does make sense that being force fed and supremely squeezed would make things a bit tense tune-wise. Just a thought.

[VMATT500C]

Is this chevy 6 for a resto or HOPUP?

[fiatnutz]

@VMATT500C - It's a restoration, but with a 194 head w/big valves and a cam - nothing too radical.

[freonr2]

You said there are more steps to cleaning. What else do you do? Just repeat these steps or do something different?

[fiatnutz]

@freonr2 - The block will be washed several times (after honing and resurfacing) prior to returning it to my client, and yet again before it is assembled..

Id love to work in a place like this.

[ironlionkalo]

does the heat affect the temper of the metal engine block?

[fiatnutz]

@ironlionkalo - Not that we have been able to measure. I do notice that aluminum becomes more consistent with a reading of 70-72 Brinnel hardness. This is especially true on heads that have torching where you will find numbers in the 68-76 Brinnel range. Great question!!!

[coolguy23448]

NICE!

[yamasubaruger]

Spiffy!
