'Summit' style mock up block?
So I got a marketing email the other day that had a picture of a sheet metal, tab-and-slot assembled mockup block (it was for an LS - they get all the love these days). I figured I've got most of the RV8 drawn, I bet I can pull shapes from my drawing and get one made for my project.
[www.summitracing.com] I've printed outlines of the individual panels so I can check them against my block, and then I'll add the detailing such as the tabs and slots. Just for a reality check, I uploaded files of all the pieces to a water jet place, and the quote in .030 steel is about $165, shipped. It'll go up a little as more detail is added, but not much. Any interest, once I get it all dialed in? Features you'd add, or delete? The Summit ones have brake-bent stiffening edges for some of the longitudinal parts, for instance. Adding the bends would add a little to the price. I no longer have a 300 block, so I can't check its fit - but I recall the only significant difference was bell housing pattern and deck height? Not looking to charge anything -I'd just make the cut files available to whoever wants them so you can get your own parts cut. But if there's interest I can maybe move faster! |

Re: 'Summit' style mock up block?
I would be interested in a 300 version. I do also wonder about the same thing Carl mentioned--is there a good reason to make it from steel?

Re: 'Summit' style mock up block?
The bare aluminum block probably weighs no more than a plastic or sheet metal mockup. I'm guessing there isn't much of a market for this product.

Re: 'Summit' style mock up block?
Joe, that may be true for the Rover or Buick 215 V8s, but the 300 block is cast iron, so I don't want to be moving that around too many times.

Re: 'Summit' style mock up block?
The reason for steel, as the Summit ad mentions, is to allow welding and other "rough" fabrication methods.
Motor mounts and headers could be made directly from the buck. Firewall or frame mods that involve hammers, plasma cutters, a sawzall, and zip disk would be easier with something that can be placed and removed with one hand. The weight in .030 steel of the long block model I have now would be 8.5#. The drawing files can be pdf and eps, for someone to print and spray mount to cardboard or foam, or send to a water jet if steel would work for your build. Eric, for the 300 I'd be happy to do a version that pushes the heads out to accommodate the 9.543 deck height, versus Rover's 8.960. You'd have to check your own motor mount hole spacing though (and the bell housing...). After printing copies of the front, bell, and skirts, checking hole alignment and sizing, I made some adjustments, added tabs and slots, and checked pricing on the updated shapes. Since there's some more complexity and fewer parts can be duplicated for L/R, the price has gone up to $212 at the water jet site I've used. Edited 1 time(s).

Re: 'Summit' style mock up block?
The 300 uses the same motor mount bosses and the same spacing. I think the bell shares 2 common bolts and the dowel pins. Also has the front and rear lifter valley wall coming up to the intake manifold and straight across.

Re: 'Summit' style mock up block?
Thanks Jim.
I've put pdf's and eps files in a Dropbox folder that I use for engine stuff to share: [www.dropbox.com] The only difference between the drawings for the RV8 and the 300 are the shapes of the end walls (since I don't have bell info for the 300). If you want a steel mock up, upload the eps files from either the RV8 or 300 folder to a water jet company and specify .030 steel for the material. If you print the pdf's, they're set up for 36"x24" paper, and from Acrobat the Page Scaling needs to be set to "Actual Size", using a printer that allows this page size. Places like FedEx/Kinkos used to have large format printers available, or if you have trouble let me know and I can ship paper copies. Edit after oil pan discussion going into page 2: The above files include an oil pan template patterned off of a GEMS 4.0/4.6 engine (and ARE’s dry sump pan). I believe it is also the same pattern used for earlier 215’s and 3.5’s. The Bosch engines, and the 300, each use a different pan pattern, so you’d need to drill your own holes based on your own pan’s bolt holes. Edited 1 time(s).

Re: 'Summit' style mock up block?
Chad, thanks--this is great. If I want the 300 version, how do I pay you for it?

Re: 'Summit' style mock up block?
No money for me, unless it’s to cover shipping paper copies.
Download the eps (Adobe Illustrator) files in the “300 Mock Block eps files” folder, then go to a water jet outfit. I used SendCutSend to gather pricing since their site is so easy to use. Let me know if any steps trip you up. |

Re: 'Summit' style mock up block?
Thanks Chad, I will give it a try. I really appreciate it.

Re: 'Summit' style mock up block?
I don’t know what models each of the oil pan patterns goes with. The jogged-over side was on the 300 when it came to me, but if that’s a 215 pan that’s interesting.
There’s a pattern out there that is mostly a rectangle, with one diagonal corner - P6 or some such. I think all the 3.5, 4.0, & 4.6 Rover engines fit the pattern I used. I’m not a British V8 historian though! |

Re: 'Summit' style mock up block?
No, that is a 300 oil pan. Mine does not have that offset on the right side. The other one looks like a Rover 3.9/4.2 oil pan.

Re: 'Summit' style mock up block?
I’ve started with a very stock mid-90’s 4.0 with crank/gerotor oil pump and no dizzy conversion. I’ve looked at the bolt pattern underneath and there’s no way that oil pan would fit my engine. I’ve got the old pickup tube in a bin - I’ll see where it joins the front cover. I’m all curious now!
This site seems to indicate just the 4.6’s used that clipped-corner pan shape?: [www.crank-scrapers.com] |

Re: 'Summit' style mock up block?
I have one of his crank scrapers for my 3.9 from back in his early days. His website is not real clear (to me, anyway).
Seems to depend on the year of the 4.0. I could be mistaken, but I was under the impression that all of the crank driven oil pumps used the front pickup location. It gets a bit murky as they switched over to the 4.0 & 4.6. [www.roverlandparts.com] |
