Mild 6.0L Build Suggestions?

I have the BTR stage 3 cam with a 3000 stall Circle D.

Very Awesome!
BTR makes some of the best cams for all applications.

I am a slow mover lol I am currently soaking accessory brackets in degreaser... retaping harnesses etc. I spent 3 or 4 hours perday cleaning up pieces like new as I put back together.

Yeah I think the lifters will def make it a bigger cam as factory spec lifters hame something like double the plunger movement. My biggest worry with that is will it beat up on the cam as there is decreased dampening. Guess I will find out. I hope to check lash a couple more times after break in periods.

I was just kidding on the hurry up and start up.....take your time.

On cleaning.
I do that too.
Sometimes I have parts bead-blasted and then I paint them......always looks better that way.
Especially on the iron parts so they don't rust.

Your cam will be fine.
The johnsons and the dual springs just require a different maintenance cycle.

Forgive my novice... what is different about the maintenance cycle? I kind of assumed that after a few thousand miles if preload was same should stay same no?

As for startup straight manifolds or with exhaust hahahahhaa

My neighbors will kill me but totally worth it.

On dual springs and high or semi-lifted cams there are multiple schools of thought for maintenance.
Some say 25K miles pull and check others say 60K.....referred to as head refresh. But more often than stock.
On the johnsons I've heard one check after first few hours, then 100 miles, then should be good.....I dunno, not my area...LS1Tech guys do that stuff.

On start up its up to you how loud. I'm just interested to hear the johnsons and the lope of the cam.

Like this YouTube Tahoe with a cam.....his lope sounds really cool. Best sounding Tahoe I've ever heard.
But maybe its like the BMWs that have audio enhancement for engine sound.

If you're going to "upgrade" the injectors, 25# are going the wrong direction, you'll want the 50# injectors, thats what I have to go with.

The OEM 38# FF injectors are what I started with and was at 100% duty cycle at 5900 rpm. I will get the part number for the injector I got later today. Once you swap the injector you will have to tune it before you can fire it up because the fuel tables will not be scaled right and you will flood the motor with fuel and probably hydrolock it

Hydrolpcked with fuel... bad memories. Def want to be careful of that!

LOLOLO--That's mine! No audio enhancements. That's exactly how it sounds in person--but LOUDER!

I cannot figure out where a few items go here...


This grounding strap comes off the harness going down across the front of the engine. The battery negative cable goes to the side of the block around there. Does this attach in the same place?

This bracket was attached to the back of the steering pump (I believe). I cannot figure out how it was oriented.

No clue the purpose of this. I recall it was attached to the passenger side head. This is the only orientation it would fit... or does it go on the back of the head? I cannot remember nor do I know what purpose it serves.

This was in my bag of bolts for the AC compressor / bracket. I cannot figure out where it goes though? Short bolt, has a washer on it.

That bracket protects the rear of the hard fuel rail--pretty sure on the pass side, but not positive. Mine is missing.

 

[Matthew Jeschke]

Awesome thanks! I should have taken more pictures!

I bolted a catch can bracket to that hole in the head.
It was an easy path to the valve cover vent....

Not sure on that grounding strap. Really, if it's a ground, it can go anywhere on the engine or frame. Where does the other end go? You should do a Big 3 Upgrade anyway.

On that PS bracket, the single hole end goes to the side of the engine block. You'll see a hole for it.

That odd plate is to protect the rear of the driver side fuel rail. It fits the front passenger side because the heads are identical and just flipped around. It goes in that same position, but on the opposite corner.

That short bolt is either for the ground strap on the upper LH corner of the passenger head or it's the bolt for the engine block side of that PS bracket. I've always thought that PS bracket bolt was black, though. It having a washer and being in the A/C bolts bag tells me it came from that side of the engine so it's likely a ground strap bolt.

 

[Matthew Jeschke]

Hey @iamdub thanks for the help! I got most everything figured out cept that black bolt. I will investigate your tip...

I will also do big three upgrade. I should probably install a newer high output alternator when I am at all this too. Not telling how much longer my 20 yrs old 240k mile factory original will last.

I have a stud on behind passenger side head. Nothing is attached to it. Curious what it is for.

Also I noticed a grounding strap from firewall by brake booster. It is not connected either. Doesn't reach side of block behind power steering pump. Does it connect to the ground lug on block by rear of valley cover?

Otherwise getting close! Nothing is torqued down though just set in place waiting to look up torque specs. If I fired it up parts would fly everywhere [emoji1]

I found this but the drawing is a bit confusing...

 

[Matthew Jeschke]

Ah crap, the diagram makes sense now. I found there's a 3rd grounding point on back of engine, above transmission bell housing and below cylinder head. Somehow I need to squeeeeeeeze my tiny little hands back there now, clean up the paint on that point and secure the engine ground strap to it.

The fuel line bracket and grounding for that harness / G104 must also hook into that same point on the engine?

 

[1BADI5]

That ground strap from the firewall near the brake boost should bolt to the back of the driver side cylinder head

 

[Matthew Jeschke]

anybody know where I can get a new one of these...

It goes inside the front bumper and up to the core support.

That's the ground strap that bolts to the hood.
