Sweet video. I love the side mounted camera!

[Mars]

Yeah my buddy is an automotive journalist and he lent me the big money camera for a bit. haha.

[Mars]

Alright, so it blew up haha. Don't worry though, I had fun doing it.

What I thought was the issue, and what I figured out was the REAL issue...

1. #1 conecting rod was broken right off at the big end.

I figured just the high boost was enough to break it...

BUT

Then I started to investigate, noticed all my pistons had been hit by the valves, which I found a little wierd...... turns out my camshaft locating dowel was wiped off the cam. The valves hit the pistons and bam caused it to blow a rod.



I may have gotten a bad / weak cam ? The cam bolt was good and tight when it came apart, and when I did the original install it was torqued to spec.., so I know all that was tight.

Now I have a race next weekend and have to run a lame stock cam.

Anyone here had this happen ?

Also the newer style of timing set was holding up great. Gears and chain showed virtually no wear. This is the tiny chain that would come stock on a '06 G6.

Picked up 2 more motors, the price was right at 400$ for the pair. 72,000 and 76,000 Kilometers.

I bought a 3500 for parts a couple of years ago that had bottom end damage, the #5 rod was broken at the big end and the rod went through the cylinder. No idea what happened, crank was ok, cam/chain ok... it was an '06 out of a van with 12,000kms on it
looks like your clearing out stock at Bowmanville!

where is your race at? I want to see this thing in action!

More pics here of how this really buggered up EVERYTHING. lol.

Pan, I just about re-used it because it already has the #10 oil drain fitting..., then noticed the crack... see beside my bottle opener skeleton fish there...



Inside :



See the pin stayed attached to the gear...



Bent Valves :



Replacement 3500, drilled out oil pan for #10 drain, waiting for my repaired cam. I put in the strong valve springs :

That is all HOPEFULLY running next Wednesday...

Mars,
I have seen numerous broken pins and all but a few had obscene cam bearing wear. The timing gears had recently been removed on all the others which seems to imply improper torquing. IIRC, GM revised the torque spec for the cam bolt but I always go 10 ft/lbs over the revised number. We had one customer who drilled and reamed for a second pin after his failed.

[Mars]

I got 103 ft/lbs. Ill loctite it too. Yeah the machine shop has drilled a second hole in my cam and added an extra pin already I'll grab a pic later on.

[Mars]

boom back on the road racin this weekend... hoping to smash so records..

[Mars]

Well we are in race mode :



3500 V6 badges !!



Yup, I cut apart the plastic stock intake manifold covers, and glued them to the car. HAHA one on each side cause I had a couple spare 3500's....

Hopefully we get some reliable passes on the weekend.

[GEARS]

That is one Boss 3500! I am suprised how much abuse your cavy takes. You run a stock bottom end on your forced induction motors right?? Cool stuff!

[HOYS]

Everytime I see someone have success with a 3500 F-Body I really...really want to do one myself and go to craigslist to find that they are all rusted out or overpriced because somebody bought the entire Jeg's catalog of 350 parts and slapped them on.

Looking very nice!

A picture of a picture that I bought from the track photographer...

Vids to come.

The racing was rained out today. Last night made it to 8th place but lost due to a -0.012 red. I staged a little deeper than usual to cut a real close one and well, I shouldn't have done that. It bit me.

Car ran a best of 12.3 @ 5 psi. I tried it at 8 psi and it still went 12.3, but was missing and running like crap due to too much fuel. At 5 pounds it ran just awsome though. I added WAY WAY too much fuel over 5 psi (I wanted to be safe), but with the meth and too much fuel, it wouldn't burn it.

I ran without a hood cause it was flopping around at 100+MPH. Everyone that walked by the car stopped and looked in, car turned alot of heads cause it's not the same old SBC camaro... Can't wait to really unleash the potential of it.

Hooks hard, no wheelspin at all cause the turbo takes a while to spool.

I'll have vids later on.

[bszopi]

Awesome! Can't wait to see the videos.
