Junkyard magnums typically have good bores, but the upper bearing shells in the rods take a beating when the plenum gasket goes and the engine eats oil. And they all did at some point. Most guys only check the lower shell and they look great. Also, the cam bearings on higher mileage junkyard...

Read post 7 above. He has experienced boost in a slant and told us all about kicking head gaskets out of it because of detonation.

Nitrous can be harder or softer on the engine depending on when it’s activated and how much is activated. If you hit the button after peak torque you can make a nitrous deal live a long time. The head and deck being flat is super important, I agree, but also the timing curve.

Sorry if I missed that part. Again I’m not trying to be an ***. But with boost (or nitrous as Charlie pointed out) you better have your poop in a group or **** goes bad.

A good video with a visual representation of how, when, and why you check valve clearance.

I disagree. The slant only has 4 head bolts/cylinder and they’re only 7/16”. It’s actually hard to keep gaskets in a boosted slant, even at 5-8psi. I have a lot of experience with engines in positive pressure (although never done a slant) and I would not build one for boost without mls gaskets...

I now own the magnum crate engine Holdener was using for testing. With the 212/218 cam and an rpm air gap it now makes 365.

You’re blowing head gaskets on a naturally aspirated slant 6 and you think the solution is boost and copper head gaskets? You should probably dial in your tuning skill on the NA engine before diving in to the world of boost. Sorry if it sounds like I’m being an ***, but little problems become...

Yea I agree with @Newbomb Turk it’s nice to have that many options for placing bleeds where you want them to really dial in the curve. It’s insane that carburetors nowadays come with this much adjustability and no proper instructions on what to do or how to do it. It’s almost like they should...

Use the brass that’s there. Solder the hole closed and drill it to whatever size you want.

So many questions, 1. Is it a hydraulic roller cam? 2. Does it have adjustable rockers? 3. Do you know what the preload is? 4. Do you know what the bearing clearance is? 5. Have you tried any adjustments to get the noise to stop/quiet down? 6. Does it have stock magnum roller lifters in it...

Couple pictures for updates. Rocker stands, shafts and rockers, thanks to two members @Rocket for the shafts, and @B3RE for the stands. And some mirror image 67mm goodness.

I guess that’s a pretty good update, I mean at least the fueling is dialed in and the timing is stuck low so you can drive it and not grenade anything. You’ll get the timing figured out and it’ll be something simple I hope. You’ve got all the hard parts done. Now just the finicky shtuff.

I recently bought a 300hp crate magnum from westech that Holdener was using for dyno testing and he installed a comp 264r-14 extreme energy computer controlled cam in. Picked up a bunch of power.

The difference will be in the idle quality and overlap. They generate a stronger map signal which the ecu likes. So, they idle smooth and aren’t too rowdy. Still make a good improvement over the stock magnum cams.

The real information is coming from the John Force Racing Facebook page. Go there for updates.

Post a link please. Most of the pages reporting that are fake BS pages.

Good news from JFR

Update, I got the rocker stands from Mike at B3 racing. @B3RE you do an exceptional job, thank you, the stands are beautiful. I’ll have pics later. I changed the adjusters in my crane gold race rockers from ball to cup, and measured for pushrods. Ordered those last night from summit. Comp had a...

Well that sucks, at least you’re better now.

A wonderful explanation from Tuner off of another site where the question was asked “how does bleed air effect the booster signal?” “Gentlemen, As always, circumstances alter cases. For the purpose of a thought experiment look at the carburetor from the often referred to opposite point of...

What did I win? :lol:

3rd gear

3.91 and a 4 speed.

There’s about 6 people on that list I’d like to see back in a car.

That’s awesome. Very cool work truck. A fleet side is just a straight regular truck bed.

@Princess Valiant shortbed? Fleet side? Wanna sell it if both of the answers to the above questions are yes.

30hp is a huge number for that 406 to pick up with a carb swap on the same manifold.

On adapters or was there a corresponding manifold change with the carb change?
