Yep, you can officially place orders tomorrow the 24th for the LS7 with the manual T-56 six-speed. As soon as Manny let's me know the six-speed automatic 6L80 version is good to go, I'll post it here as well.

Is that Dark Bronze from the Testors lacquers line?

I think the purple fits the Olds well. Great looking build.

Looking great.

Looks good so far. Can't wait to see some color on it.

Very nice work on the weathering.

Basically what I'm seeing is necessary to do an LS9 crate motor in scale is to raid the ZR1 kit for the manifold pieces, front cover and belt/pulley assemblies.

I did a quick Google search and found a few places selling the LS9 as a crate motor. I know the ZR59 SEMA Vette that is inspiration for my own '59 Vette used one. The Stielow Camaros use the LS9 upper on the LS7 427 block.

I was hoping that the ZR1 LS9 setup would work as that would be fairly straightforward. After seeing these pics, there is quite a bit more scratching to be done. The upper part of the manifold for sure. I'll have to pick up a ZR1 and see how that kit's pieces are laid out to see if it'll make a good base to start from.

Thanks for the heads up on the differences.

Yes, Klaus is using the angled-face 18" x 24" opening dimensions in his calculation which is correct. But, the point you both have missed is that the actual cross-sectional area of his booth is around 17" x 24". So when the air leaves the opening of the face and enters the body of the booth the airflow is actually slightly accelerated by being forced through the smaller area. By calculating for the slightly larger opening you can ensure that the column of air through the booth maintains a sufficient velocity. Air is not empty space. It is full of molecules that have to be treated like a fluid where motion is concerned. So in the case of a booth you have to move all (or a great deal) of the molecules that are in the space between the fan and the opening. In the case of this booth, you have exactly the opposite scenario of Klaus' example. You have an extremely small opening and a large cross-sectional area. Once the air passes through the inlet filter into the box, it will decelerate rapidly as the molecules coming in have to fill the much larger column of the booth. That 100 cfm fan has to move all (or a great deal of) of the molecules in that 2' x 3' column before it can exact a draw on the smaller inlet. To actually obtain 50 fpm at the fan in this case of the enclosed booth, the air may have to hit the inlet filter at nearly 100 fpm to overcome the inherent deceleration of hitting such a large working column. If you want an example, take a drink with a straw from a glass and see how easily it pulls. Next take the large end of a funnel and put it over your face and try to take the same sip with the same effort. It's not going to happen. The straw has the same inlet and working area so it is relatively simple to draw your column of fluid through it. The funnel has the same roughly the inlet size as the straw but a much larger working column and as such requires a great deal more pull to achieve the same effect. Quite simply put, you have to maintain the rate of flow through the largest cross-sectional area of the column of air. It does not matter whether that is the opening (as it is with the angled opening of Klaus' example) or the large working area of the booth in this thread. On the exhaust side or second part of the equation, the ducting is so much smaller than the area being vented that the molecules of air can get stacked upon each other and create a back pressure. So in picking a fan you have to have enough pull to maintain velocity on the inlet side and overcome back pressure on the exhaust side.

With this dropping Monday, and I have no doubt that it will be a success, what do you guys want to see next? We've already added the automatic version and the exhaust manifolds into the mix based on feedback from here. I think that the supercharged LS9 from the ZR1 would be a no brainer. Or a carb'd intake. Perhaps the flatter dry-sump oil pan that is used in some 1:1 builds. Manny has briefly mentioned in one of our conversations wanting to do more with this based on the buzz that he's seen here on MCM.

I will respectfully disagree with that logic. Greatly exaggerated to make my point, following the method you stated, one could in theory properly exhaust a full-size 8' x 10' x 8' room through a 1' x 6" filter with a 25 CFM fan as that combination would have a proper rate of flow at the filter. There is no respect to the area being cleared and outside of the immediate area of the fan the pull would be virtually non-existent. I have read and re-read Klaus' article many times over the years and have exchanged communications with him several times. In his guide, he always refers to the square area of the box dimensions when calculating the first portion of the flow needs.

I almost forgot. There were a couple of guys that asked about exhaust manifolds and these from the Revell '10 Camaro SS I felt were the best option of all the various Revell LS motor-in-kit-form options. I cut them off at the flange to remove the cats and I think they will serve well to fit a lot of different configurations.

Very cool concept.

Good looking build. Love the black on black.

That's a great shade of blue for the Vette. It looks like it's coming along nicely.

I was just over at VCG's site finishing up the bits and pieces I want to add to my order and noticed they've added the LS7 to the top of their page. Manny is planning on sending me some more pics to post here but you guys can get a sneak peek there. http://vcgresin.atspace.com

Both great looking builds.

Absolutely no fault to that logic. As I said before, I think it's a brilliant design. Safety is the top priority and if you can eliminate the ignition risks and ensure that your system can keep the box cleared of fumes you are golden.

Masters for the T-56 six-speed manual. And the 6L80 six-speed auto. I just have to clean up a little flash and drop these in the mail.

That article by Klaus is the best. I've built a couple of booths following those guidelines. All of mine have been of the downdraft variety as they tend to be cleaner and more efficient.

VCG's website is here. I know that the crate motor with the manual tranny is ready to go as I have seen the test shots. The automatic will be ready soon. He had me post next Monday as the official release date so that he has this week to build inventory and be ready. http://vcgresin.atspace.com

I just got off the phone with VCG. They had sent me some pics of the first parts out over the weekend but the email never made it to my phone. Everything looks good in the pics he sent me and he wants to get some better ones to post here. They will be ready to take orders on Monday the 24th so that he has some time to build an inventory to fill the first rush of orders. After talking with him, they will be available as the full motor with a manual, full motor with the automatic as well as having the two trannies available as a stand alone item. I'll get the new pics up as soon as they hit my inbox.
