    Re: Sneak peek.

    Damn. Can you give us a rundown of what's on that thing? It looks like you've got provisions for an oil cooler or remote oil filter. I have no idea what that extra pulley is, but I assume it's supposed to replace the tensioner that's usually on the driver's side.

    Also, how do you plan on handling the initial startup? I've never understood how people get these things started the first time. Everything has to be totally wrong.

    Re: Sneak peek.

    I have had an oil cooler on for years. That's a sandwich adapter that opens at 160 degrees. It's been fine with -8AN lines. The cooler has an integral fan that I put on a switch, it can also be setup to turn on and off with a thermostat.

    The pulley that replaces the tensioner pulley is for my GZ Motorsports vacuum pump. The pulley that is on the driver side is simply an idler pulley that attaches to the alternator bracket.

    The initial startup shouldn't be that bad on this motor since I'm going from a 417 to a 427. The cam is a little different and the intake is different. It should start up just fine and idle ok by itself. I'll tune in the MAF and drive it easy until I can get to a dyno. I have an appointment for August 13 on a dyno.

    Re: Sneak peek.

    Can I ask about the purpose of the vacuum pump? I just looked up a couple of vacuum pumps online, but I can't find a good explanation of why it's beneficial (beyond "vacuum = moar power!").

    Re: Sneak peek.

    Stock PVC system isn't sufficient to create a vacuum inside the crankcase with the stroker motor. The 418 LS3 was creating positive pressure and blowing oil back through the intake tube and filling my catch can every 2-3 days.

    Plus..... vacuum = moar powa.

    Re: Sneak peek.

    This has been sweet to watch. Me and my dad are doing a 75 vette with your basic 350 with a few upgrades but this thing is a work of art for sure. This transcends my knowledge by far! Someday I will be here but that is a long time coming!

    Kudos for your work so far and all the general knowledge base you provide to the rest of us!

    The second part makes the vacuum pump sound like some kind of free energy/perpetual motion machine. What are the downsides or limitations? There must be a reason why we don't see this as a commonplace bolt-on.

    By the way, my LS2 has yet to deposit a single drop of oil in my catch can. I checked my hoses to see if I had some kind of blockage, but I could suck air out of the engine no problem.

    Thanks. I appreciate that. I just finished up a 383 stroker sbc for a buddy. I rebuilt the motor, upgraded to an hydraulic roller camshaft and cleaned up the engine bay. I took a lot of pictures along the way. Hit me up if you want to see them. Most are uploaded to my Facebook page.

    As far as I can see the drawbacks are the cost and having to drain the catchcan often. That's odd that you don't have any oil in yours. I always got at least a little with my LS2.

    I usually empty my catch can during an oil change (it is ususally about 1/4 full) but the internals are bone stock on my V.
