Correct ~

Headers are thinner and don't ' crawl ' like cast iron exhaust manifolds do .

FWIW , you don't " tap the holes " as they're already threaded ~ just use vise grips or a stud remover to remove the pins then use an appropriate size bolt .

When mine were removed they were not threaded, they were pressed in. The holes were in fact tapped.

Another thing learned here ~ thank you ! .

Do you know what year the head is ? .

I'm curious as I have never seen the alignment pins pressed in .

I've posted on here before, but thought I'd share my recent ongoings. Recently pulled the engine and trans for a complete rebuild while I restore the rest of the truck. Thought it was funny you can see where I repainted it while in the truck. Apparently I couldn't get the back of it!

Hi Slick, I have a '63 292 core block that has that Detroit Diesel Alpine Green still on it from the factory. I think that was the only year for that green and then only on 292s, but it's your truck, and it does look good.
What HEI distributor is that? Looks like a Mallory cap. I did not know they made an L6 product. I have a Pertronix Ignitor II kit in an Accel Blueprinted AC/Delco distributor, but I get this high RPM cut-out gripe and I'm thinking of going full HEI.

[VWNate1]

DO go the HEI route ! you'll love the added power and smoother running .

Forget about any missing , ever .

Well for some reason or another when I originally got the truck the block was the Alpine green and the head and valve cover was chevy orange. Who knows. But when I cleaned it up and repainted I thought the green color looked better against the orange/copper color of the truck. However after the rebuild I will be going another route. Stay tuned.
The Distributor is one of those really really expensive (sarcasm) FleaBay deals. Looks and works great though, except never could get the vacuum advance to work properly. That may have been operator error though.

Sounds like the PO just stuck a '67 -'68 head on a '63 lower block. All do-able of course. The '63s had a forged iron crank with 6 lobes. The '67s and later had cast steel cranks with 12 counterbalance lobes. Better balanced, but the early ones could be 'knife-edged' for frictionless splashing thru the oil sump. It's a drag or racing thing, from Leo's Grimoire of L6 Black Majick.

Your truck, your colors, no problem.

Most of these hi-perf aftermarket distributors have a variable adjustable vacuum advance can. I think you can use a 3/32nd" allen key to dial in vac advance adjustments. All the way clockwise is O* additional advance IIRC. Crane Cams used to have good instructions you could download. You might try Jegs or Accel's websites for that data.

Your red distributor looks like a Mallory or MSD. I looked one up on the internet, but it looked like you need the MSD box to play with their distributor. Also listed for $329. About 3.2 times more than I want to pay.

On the way home today, my 292 started running hot, then cut out at about 45 - 50 MPH. [Air temp about 100*. 40% humidity. Uphill run. Truck parked in sun during 7 hour shift.] I coasted into a Safeway parking lot, turned off the Ign Switch, re-started again and it started up. I was about 3 miles from home, and I made it driving carefully.

L6s very rarely will vapor lock.
I think my Pertronix Ignitor II is cooked. Looked like an unusual eccentric wobble. Could be the water pump going too.
I'll either get a new HEI or try the old points distributor for comparison.

[2002yanks]

Figured i would post some updated photos of mine. All installed in the last week. Offenhauser 5416 intake, edelbrock 500 cfm carb, stovebolt cast headers, and 2 1/4 duals with 22" cherry bombs. Also installed a 194 head.

Pic 1 is shot of carb and intake from drivers side.
Pic 2 shows the throttle setup. I used a lokar throttle cable with a bracket i made to mount off the bottom of the carb adapter plate.
Pic 3 and 4 are complete shots(before we cut the throttle plate down). Shows my new valve cover also

Speedmaster makes a nice HEI. I was able to do 5000 rpm with my stock 292 no problem. lol

Thanks for that tip, TJ. I see Skip White in the mix there too with kind of a hard sell...
Is the AMC distributor different? I remember the old points caps used to list AMC [+ IH] engines on the side of the boxes. Are the gears different?
Not seeing "Late Chevy L6" distributors under Speedmaster. Just AMC and GM V6.
KMJ Performance looks interesting. Unbelievably low prices.

Here's the dizzy I have. Sorry I meant Speedmaster79.com. Sometimes it doesn't always work. lol

all aluminum I-6. Weighs 383 lbs.....normally aspirated and makes 480 HP at the flywheel on 92 octane pump gas. Fun is the word I would use for that motor in a pickup truck!! That's the stuff legends are made of.

Hmm, the Ryan Falconer L6, available as a crate engine, starting at a mere $45 grand. This was co-developed by Ryan and GM for their Baja Trophy trucks and Pikes Peak hill climber trucks. The engine is loosely based on the 292 but is 24 valve and DOHC. The 4.2 liter trailblazer 6, also 24 valve and DOHC, was also used in some of these trucks and what I am using in my project, at about $44 grand cheaper and not that much less capable.

Oneupmanship used to be a sport. Tell you what, since it's 44 grand cheaper I'll take one....for 500. You can ship em COD.

[VWNate1]

LOL !

Come work for the Police Dept. ~ oneupsmanship is alive and well ~

Most of the ones who're really invested in it , are middle management boobs who'll never make Captain and so are suck telling everyone below them how lame they are...... .

Me , I love looking at this monster engine because , well , POWER , right ? .

Nevertheless , I'll keep my old tech 250 / 292 6 Bangers .

Sorry, Nate! I'm going to pass on your invitation. I like retired life too much. I get up when I want to, play with my toys on most days and sometimes do something foolish....like paint the house.

But I do appreciate looking at a fine piece of machinery and, well, you know the rest!

I got mine from Louisville shipped to SoCal for $1200 with less than 10K Miles on it.

The down side is they chopped up the wiring harness with a sawsall, but I didn't need much of it anyway.

[eagleuh1]

My 50 GMC 270, stock except Chevy TBI and Fenton duals with Porter mufflers, stock distributor converted to HEI. Top speed went from 47 to 60 on flat ground with these mods. 10,000 lb fire truck.

[6cylinderstepside]

Here's a few pics of my 250 in my '71 with a '79 Stepside bed...

1- Standing next to the engine bolting up the transmission. Just another cool benefit!

2- The completed engine with P/S and AC

3- Does anyone else have a spare valve cover with the top cut out of it for setting the valves with no oil splatter?

4- My new project is a '79 stepside with this integrated head six that runs really solid also with P/S and AC. Since the brackets are different for those rare items from the conventional head, I am going to run the integrated heads... I am going to swap the Saginaw three speed for the TH 350 next.

Question... Do you have to use that multilevel integrated head valve cover? I hate the way it looks. Can I use one of those tiny air cleaners and a classic 250 valve cover or are they different?

['68OrangeSunshine]

I have an L6 valve cover I've been meaning to cut out for a valve-adjust piece, just haven't needed it yet.
Nice 250. What carb is on that Offy intake?
I have never messed with the integrated heads, always been steered away. I hear the later blocks will take an earlier head ['60s + '70s].

That's a regular 2BBL from a V-8 with an adapter plate. I was on a budget and just used what I had available. It ran fine and I never got around to putting a Holly 390 on it which was the plan. I am going to keep this new one stock as far as carburation goes. I'll probably do a marine or RV cam and that's it when I dig into it. for now if it ain't broke, I'll focus on other stuff the truck needs

On point #3. I would not use that method. You can buy plastic oil stoppers that clip onto the rocker arms. I have bee using these for years and you get no mess. You also get better access to the valve assemble and you are not fighting the cut opening. The clips are not expensive and will also fit small block Chevy rockers as well.
