Be a great opportunity to see what the power difference between iron and aluminum blocks are. Then how much the weight savings picks the car up. Never seen a better opportunity than this.

I had it shipped directly to my machine shop, and in the excitement forgot to take pictures. BUT i did get and extra flyer in the box so hear are three pics with info. Maybe Todd can post a picture of the back and side of the BMP blocks to show the oil passages. The Specs say "Priority Main oiling", but it looks like the lifter galleries are fed like a stock Chrysler block, with the exception of the BMP having bushed lifter bores and 0.035" feed holes in the bushings. The front picture appears to show a Driver's side main oil gallery, but I can't see the side/back. I wonder if the blocks come suitable for pushrod oiling? The bushed lifter bores with the little 0.035" hole for oil has to align with the lifter oil hole (when cam on base circle?) to send oil up the pushrod. And the 0.035" feed holes should help protect the mains if a lifter gets thrown out.

I don't really know, but the BMP "World" blocks should still be fine for over 1000 hp. But for 2000 hp, the KB design may be helpful. LOL That was my thought.

FYI not all KB blocks came with a pair of cross bolts in the caps. I have had both and was never asked or seen on the old order sheet where it was specified. When I bought my KB in 2006, Ken Black asked me if I wanted double side bolts. I said I didn't think they were needed for my application, but he said it was a no cost option...so I got them.

Never was asked here, I still have the order sheets for the four I've had. Interesting FWIW have had two of each

I visited another racer in North Carolina today to look at the BMP/World aluminum wedge block he bought last week. I liked what I saw, and it is great that Todd Marsh Performance in NC is getting them and supplying racers! I am going to share some of my initial impressions in this topic, since Greg sent his directly to his machinist! The info sheets that come with the block (and available on Bill Mitchell web site) says this: Cylinder Head Bolt Holes: Blind tapped and do not extend into water jacket. A longer than stock stud is required for the valley bolt holes of this block. I did a quick measure of the head bolt holes and all of them seem to be drilled the same amount, about 1.33" deep. That is the drill, not the threaded depth. The depth of the drill tip vs the full drilled dia may vary +/- from my measurement. The ARP head studs I brought with me have 1" long coarse threads, and it easily threaded in the block the full 1 inch. The longest threaded 7/16-14 bolt that Mike had on hand had a tad over 1.1" threaded length, and it threaded all the way in. So the threaded depth is at least 1.1+ inches. I think most BB Mopar head studs have about 1" coarse thread (check yours). That is over 2X the stud diameter, so I am thinking that is fine for most applications. But I can't understand the Note in the info sheet, since all the holes appear the same depth.

I bought mine through Todd at Marsh perf. Each retailer will set thier price, usually discounting the retail price some. And that will change a bit as more blocks hit the market. I recommend dealing with Todd at Marsh. Knowledgeable and goes out of his way to take care of customers.
