Now we can tell you the best info on 440 racing blocks. This all new
Koleno Performnace block has been built up as a 605 cubic inch monster at
Koffel's Place and ran on the dyno.
No ifs, ands, buts, no maybes, no leaks, no cracks and, no overheating. You can see the engine running at the
Norwalk Chrysler Classic event this coming weekend (Sept. 14-16). There will also be a few bare blocks there for inspection.
These blocks are available for order from us NOW! I've been sitting on this information & photos for several weeks now and I am very happy to show these to you along with some explanations.
Photo #1 FRONT
Note: Oil hole next to cam bore @ 9:00 position. It is the priority oiling system (separate oil passages going directly to mains.) Look closely at the front main cap and you can see the cross bolted mains. All 5 main caps have cross bolts. All initial blocks will be the "RB" (440) blocks as shown here. Hemi's will be coming next and then, hold on... "LB" 400's, GET OUTA HERE! Would I tease you????? That's the plan.
Photo #2
Note the oil passages around the cam bores. The ones @ 11:00 and 1:00 are the lifters and the one at 3:00 is for the mains. Cross bolted main bosses seen here too. All 5 mains are cross bolted.

Cut away showing the priority oil feed to the mains first and then up to the cam bearings.
Photo #4
This is a cut away showing the cylinder wall. Can you say thick? Sure, I knew you could. But can you believe it??? The designer had some good input. Look at those husky main bearing webs and skirts. Youzers! I guess we won't be selling 2400 main stud girdles a year when these babies get in circulation!

Large reinforcement rib in the valley also serves as oil passages from the #4 cam bearing.
Photo #6
Where's the beef? The water jackets look thicker than OEM cylinder walls. Estimated cost will be around $4,000.00. Immediate shipping available on 440 "RB" blocks.
And best of all, these bad boys are made right her in the Heartland of America. Where did you expect the beef to come from?
Photo #7
Note how consistent the wall thickness and the main bulk head below the cam bore is.
All "Factory" machining is done by Roush Industries.....Yes, that Roush.
This is an American casting of standard cast iron that can be machined, final bored, and decked as desired by any competent general automotive machine shop. Unlike the CGI (compressed graphite iron) that cannot be machined in the aftermarket.
Don't even look for any of the funny stuff like mega amounts of coreshift such as is in the Chinese blocks.
The part numbers for the blocks are:
