Wanna sell that custom crank let me know? That is exactly the crank I need, especially if it is 8 bolt. Pls send me a PM on more info on this.

I bot a new 3.91 crank for my "low deck" KB block and guess what size the mains are in the block (hint, B vs RB)? NFG, dumb azz mistake. Had to put back in the very tired Bryant 3.85 and lost 0.060 stroke and 1 point CR compared to the crank I was gonna use and already had the new pistons.

I very possibly may sell off the mega block 540 short block assy and use the Indy CNC heads on the KB motor. All new stuff with a couple run hours. Pan up. Too heavy for my regular steering box old man arms with a spool. Not a thread jack, send a PM if interested.

You can order a new crank from Crower.

You can seen the lifter valley detail here.

Mine is still in the bag and on my stand, have you had a chance to mock up the top end with the lifters and pushrod angles yet ? DK

Reasons why the valve reliefs have those nice sharp geometric shapes

By manufacturer:
1. "it's the cheapest way"
2. "most people won't pay for the extra work"
3. "it's what they expect to see"

By owner:
5%: "just got it back, on the trailer tonight"
95%: "... what?"

Do they sell a 4.5 bore Hemi block?

I've always "softened" those sharp edges. It's OK that I don't pay to have it done. More time and effort? Yep. Worth it? Maybe. I just do it.

Back on topic...I'm glad to see this block, and the Ritter SB stuff, finally looking like the issues have been resolved and decent parts finally available for reasonable money and time waiting.

For anyone who has the current version of this block: Care to describe what problems if any that need corrected on this block?

I am really hoping that they can turn this effort into a successful way for us dumb BB Mopar racers to get a good cast iron race block, finally

I still get confused when its called Bulldog. I have an early casting (was told first run) bought from Muscle Motors all called The Block. These were the issues that needed addressing:

- cam bearing bores were on the tight side
- lifter bores were crap and needed bushings
- oil pump bolt hole should of been a blind hole but wasn't causing an oil leak through the bolt
- dipstick hole too small (btw - I now have a reamer for that if anyone needs to borrow it)
- distributor drive gear needed to have the block clearanced - the gear was hitting the block
- the galley plugs in the front were hitting the timing chain

That's all I can remember for now..........

Apart from the lifter bores the rest of those issues are minor.

I'll add my 2 Cent's, My cousin bought one of the Hemi block's this past winter, Took it to Barton for machine work. Cylinder, main, and cam bore's checked good, the decks were off about .015. Distributor hole was too small. we'll see how tough it is, going in a pulling truck.

Hey guys, update on my 498" Bonneville bullet using THE Block. Finally got it on the dyno at Best Machine. This endurance build with a single Quick Fuel Dominator made 947hp at 7400rpm and 690tq at 6800rpm through my first time built 2 1/4"-2 3/8"-4" collector stepped headers that fit inside the frame rails of my Daytona clone. I now wish I'd have gone with the recommendation of a 4 1/2" collector. Best Machine did a great job with the engine. Time will tell if it holds up to the task, hopefully we will make it to Speed Week in August 2020.

I will try to compress the dyno sheets and post them here.

For the life of me I cannot understand putting the effort into manufacturing the block, then half-assing the machine work. This block was advertised to be CNC'd to perfection (my interpretation), but had a miriad of issues. First block wss swapped with the company because of an epoxy repair that was unacceptable to my machine shop. The second block also had an epoxy repair, but it was acceptable (I don't know the exact problems, I trusted Best Machine to make that call).

Known issues with this specific block-
Main oil gallery to top end was not drilled through at cam tunnel!!
The bolt holes for the pan rail were not tapped deep enough, so the bolts would not engage far enough.
One oil pump hole was not tapped deep enough.
Cylinder bores did not go deep enough.
Numerous other machining shortcomings. Other posts have a list. We used a Jesel belt drive and external distributor, so not sure if this block has distributor hole problems. Also did not use the dipstick hole as this is a Dailey Engineering dry sump setup with a custom Stef's oil pan.

The dyno info.

Well here’s the update, I took my “Block” to Todd Marsh and he put together a low maintenance combo, it’s a 540 low deck with decent ported -1 Indy heads 1.6 rockers, pressure checked the block no issues with porosity and according to Todd the machine work had no major issues, yes the one oil pump hole is thru to the water but that can be dealt with. The trip to the dyno exceeded our expectations and the target by a few, 882hp @ 7000 and 770 ft lbs @ 5800 on C16 and if I remember correctly a 1250 carb, I am going to run it on alcohol and a Ron’s Terminator so that should bump it a little more on both ends, it should have a little grunt to it.
This has been a long time coming and no fault of Todds, getting parts is a major headache, with the Indy sale and move that was a major challenge, after a long wait for an intake Todd found a used one, nobody is making anything.
On another promising note, the rumor was around awhile back that Jason Line had bought out Bradshaw and Bulldog, and I am sure it was for the (cough) Buick side, I did email him and he replied that they were looking at the Mopar side for improvements and production so maybe he can make it go. Doug

Glad to hear it worked out for you!!

I’m sure Jason Line was looking into improving thing for the HEMI side of things as well. He is building Bucky Hess’ engines, and I’m sure anyone else that will write a check.

Good deal! Always good to hear positive news about one of the available aftermarket blocks out there.

Is Jason still working out of the KB shop or does he have his own place?

I had heard he had cut his role at KB way back.

I heard he left KB, just recently.
