The balance on your crankshaft.
The 50 oz imbalance is a stock 5.0 balance weight from 198? and up.
Your flywheel has to be made for that imbalance too.

So it's down to the design of the engine? Like a fox 5.0 needs a 50oz HB and the 4.6L would need "x"oz HB?

Yeah, It just depends on how they were balanced from the factory or if that has been altered during a rebuild.

Ok, I get it now. So this info needs to be passed on to the dude assembling the engine? Sounds boobish, but I've wondered why they called it a harmonic balancer :duh:

Well, the guy assembling the engine should know all of this to be truthful.
It is called that because that is what it does. It dampens the harmonic vibrations of the crankshaft.

Goin to my local race shop later for stuff on the 454 camaro swap...anywho im gunna try and find the v traction stuff for my d/r's and some decent hood pins..
Hood pins because yesterday on a lonely road my car needed to breath a bit and I noticed that at 100+ my hood likes to dance a bit. Ive never noticed this before yesterday,but it really made think of how much it would suck to lose a hood at 100+ :/

Definately! Especially if it made you eat a ditch or taste a tree while freaking out from the flying hood.

IMO you should always use hood pins with fiberglass hoods.
I've seen several Mustangs with crushed cowl vent areas because the glass hood flew up and the cowl is a huge PITA to replace.

You know, if you'd sell all that BBC stuff you could get more goodies for the Mustang.


My Cervinis hood was doing the same thing as you described, even with the latch properly adjusted. That made me nervous, so I put some pins on mine soon after.
They have some really nice twist lock pins on the market these days, but they seem to think they are worth their weight in gold.

Yeah they had the hood pins I bought and also ones without the lanyard and the ones with the flip rings..but these ones just scream old school so I went with them..

Rivets will work, but you must have the backup washers or they will splinter the fiberglass.
Also use either SS or aluminum rivets as the plain steel will rust quickly.

Damn...the oil pan is a no go with the oil pump. The original pan was deeper so the pump had a brass block spacer we figured eliminating that and getting the stock shorter lenght pump shaft would be good,but apparently the pump pickup still sits to low..

You can buy shorter pickups for it..not sure if thats the route we'll be takin or just go with the old setup..only reason we didn't run the old pan was for a little more ground clearance. At the moment the camaro still has SB suspension..

And TH what do you mean about the washers for the rivets?..like I just place a washer underneath it?..I do have aluminum rivets.

That's one type.


Steve, You want the washer to fit the rivet snugly so when you cinch it down the washer not the fiberglass takes all of the strain of the rivet expanding. The expanding rivet will pull the washer up good and snug to the bottom of the hood, securing your hood pin plate. Even aluminum rivets will crack and shatter fiberglass.

Ooohhhhh mylanta...kewl thanks ladies...lol jk
Well the only other thing I got goin on is we installed the cam straight up BUT the marks on the timing gears are both on top instead of bottom and top..they recommend using edelbrock timing gears but I recommend they can suck a fart out of my ***!!!...the engle cam we pulled had the marks the same way and both intake and exhaust valve are closed so im takin the gamble...and no I dont have a degree wheel..

The cam gear should have the mark on the bottom and the crank gear on the top normally and those two should be pointing to each other right?


If it's wrong you will be 180° out?


You can get by without a degree wheel, but you will leave a few HP behind sometimes. If your cam was machined on a good day, then you might be ok anyways.

Yes I am aware of it possibly being 180° off but the old cam and gears were installed top and top..now like I mentioned the edelbrock cam recommends there timing gears but at the same time the engle cam setup had them top and top..so uhh yeah sunny beach!!

The cam gear and crank gear are different sizes. So if the line up top and bottom they obviously wouldn't line up in the middle. But the reason maybe cause the cam was degrees? I am saying this with very little Chevy knowledge (and buzzed). So keep that in mind.

Yeah, you have to keep in mind that the cam turns half the speed of the crank.
I wasn't aware that he was working on a GM.
I admit to total ignorance in that case.

Not in the least. It is easy for timing and valve train events to be confusing.
I still struggle with it even after years worth of experience.
It's one of those things that if you don't do it everyday, then it will not stay stuck in your mind.


Just reading and thinking about this, I think I may have given some poor user the wrong info a few days back on which way to turn the distributor to advance the timing. I can't remember who or what thread, now that's going to bug the crap out of me for a while.

In the first pic you can see how the timing marks are different (top and top)
now after that I ran into a different prob...that's when I say I want ”stock length” replacement pushrods. They gave me stock length hardened rods thicker than the pushrod guides grrrr MOFO'S!!..
im prolly just gunna hog out the guides to fit these pushrods.

Where is the #1 piston?
It should be at TDC and the cam lobes for that cylinder should be on the base circle of the cam (both valves closed).


Hope those guides aren't "hardened" too, or hogging them out will be difficult.
