The only 'fear' over an internally balanced crank is that the offset weight on the front of a poorly cast crankshaft could shear off - that's pretty darn unlikely even with most cast cranks today so I wouldn't worry about it - the bigger worry is if you're going to strap a big belt driven blower to it and the loads of the blower + the balancer I've seen cause problems way more often than a properly balanced N/A setup. The weight on the rear is at the big end so it's really not a concern...

I've raced externally balanced 400's spinning them to 65-6800 with cast cranks before and the cranks or snouts haven't failed and that was hitting those RPM's 70+ times each weekend...

Good to hear this, thanks. He was probably just trying to con me into buying the forged stroker crank they had there

As it warms up here, I will be back to the garage with a slew of pictures on the way.

I wish I had gone internally balanced, but that is partially because you have a much better selection of balancers, especially lightweight ones from ATI, than with external.

I think and hope you'll be fine, mine has lived with +400rwhp/rwtq and 6500rpm runs so far just fine... knock on wood.

Got in touch with the machinist today, he said he hasn't had time to look over my block yet. He said within the next two weeks, he will be able to start working on mine.

...the waiting continues. On another note, we got another 6" of wet/heavy snow yesterday in central Wisconsin. What a joke

Still alive,

Jeremy

My machinist has had my block for a couple months now, but I told him Im not in a real hurry, and he has only been working on it when he gets some down time. I should have it by the end of this month. This is the busiest time for the block guys. Everyone is trying to ready for racing season!

Yep, best time is in Nov-January when the racing season is over.

Did a bit of work today...only had about an hour and a half of free time

removed the mammoth starter, almost dropped it on my face. heavy bitch.

dropped the rear portion of the exhaust, because i want to change the U-joints on the driveshaft.

Tried to get at the front y-pipe to get it off, but couldn't do it because i forgot my deepwell sockets at home.

Will do more work on wednesday.

On a side note, what is this connector here? Oil temperature? I didn't follow the wiring, I rand out of time and had to go to work. I relocated my knock sensor to the drivers side, just so there aren't any questions about that. Crappy cell phone picture.

...Looks like Summit is getting tricky.

Noticed this when I was looking for lifters,

Look at this page first,

http://www.summitracing.com/search/Department/Engines-Components/Part-Type/Lifters/Make/CHEVROLET/Lifter-Style/Hydraulic-roller/Lifter-Link-Bars-Included/No/Engine-Type/V8/Engine-Size/5-7L-350/Engine-Family/Chevy-small-block-Gen-III-IV-LS-based-engines/?Ns=Price|Asc

Then look at the:
GM Performance 12499225 - GM Performance Hydraulic Roller Lifters.

On the first page, they are 129.95. When you click on them and go to the item description page, they are 132.95.

Them sonsa bitches.

Will these work fine for my application, or should I go for the howards for $30 more?

Got some stuff done the past few days.

Andrew (aardwolf) came over and helped me out. Thanks!

Removed torque converter to flywheel bolts, both exhaust manifolds, drivers side head, and got 4 of the bell housing to block bolts undone.

Today I removed the passenger side head, and started evaluating my harness swap situation. Its going to be a dandy.

The car as it sits right now

Welcome! Work on getting the trans braced too. It was fun helping and a nice burn out always brightens the day.

He doesn't have a hoist yet. We talked to his neighbor about using the one he has though.

Tore into the dash today. I want to get the harness out of the bay before I pull the engine.

That's where I am at right now.

Does anyone know what this is? Or what It's supposed to be connected to? It wasn't connected to anything, and is tucked right behind the DIC

Also, is this the dimmer timer switch for the courtesy lights? Which relay is this? It's right behind the DIC

Send a P.M. to Bill Curlee and ask him. Guy's a walking store-room of information. Seriously!
