I am amazed how a modern top fueler can make a pass without locking up the motor without coolant.

I'm assuming the Palbykin mod is the stepped area at the top of the bores for gas or solid rings to be inserted? Come on Tom, spit it out!

These blocks are cast and then heat treaded in a very special way in a vacuum oven and vibrated for 9.5 hours then water quench to 32 degrees. This makes the aluminum denser. Very close to a extruded solid aluminum billet.
Deck height is 10.240

I suspect that the majority of the blocks will remain at the standard 10.240" deck height as it makes little sense to add a sealing provision if you have not been having head sealing issues in the past.
Yes, The Palbykin Mod was the ring that Marty and Tom Earhart came up with many years ago. Tom V.

"Street car" with no water cooling... Hmm.

No street car for a all out alcohol motor.
The water jacket Aluminum blocks are also very good race blocks. J. V. Has won over 150 thousand with his aluminum IA II

Is making these blocks with skirted mains cost prohibitive ? Sure would be a lot cheaper for guys like 3fast to get one with LS/FE mains vs calling up LSM and paying through the nose.
Anyway, nice job All Pontiac. Works of art to guys like us. |

I don't know the cost difference, but it would have to be substantial. These blocks are a big upgrade for us and a few others who don't need water in the block. To make a skirted block would mean new patterns for the bottom of the block, new cores, modifications to the core box or a new box. For the small numbers we are talking about a billet block may actually cost less. The block we have now required the REMOVAL of cooling cores, some other modifications to the existing cores but not a complete redesign. This made it more cost effective and much faster to have made. The additional heat treat and HIP process improves the density and elongation ability of the aluminum. Yes a skirted block would possibly be even a better deal but would in our situation also require thousands of additional dollars to change: 1. the current 2-piece oil pan would not fit a skirted block. 2. Our entire mag drive, oil pump, blower belt drive and fuel pump drive have been configured to fit a stock Pontiac front cover. All that would have to be changed and re-designed with a skirted block. 3. One of the final identifying features of this being a traditional Pontiac engine would be gone. Not denying it may be better. I am a big fan of the Ford FE engine. It's my second favorite after Pontiac and shares some design features. We are going to do our best to have this block take us where we want to go.

Way to go Bob C.
This solid aluminum block with the added stiffness-enhancing features is the most exciting development in Pontiac race blocks in a long time. I can see others with ultra-high HP Pontiac builds grabbing one of these up, I'd bet Big Chief will be in line for one soon for the Crow Mod. Best of luck to Eric, Mike and their crew, we're all very excited in the Pontiac racing community and and can't wait so see your performance with the new solid aluminum block. Bart

A lot of folks in the nitro community were sure that our iron block would die a quick death. The thinking is that the flexibility of aluminum is needed to absorb the extreme loads. The iron IA2 has taken a beating and proven them wrong. But now it's time to take the next step. Replaceable sleeves will make service easier and the weight savings will be important. And we feel that the overall strength will be even better than what we have now.
This block will work for anyone running methanol or nitro (who don't need water cooling). The key to the power of a nitro engine is injecting liquid fuel instead of vapor, allowing a lot more fuel to be stuffed in. Liquid won't burn....it needs to vaporize in the cylinder. And vaporization absorbs a lot of heat, hence eliminating the need for cooling water. Eric

I measured the deck height of our block today. 10.235". It's also nice and square +- .001. Planning to use it as-is. Working on sleeves next.

Good news and will make your Race timing schedule hopefully.

More then most will dare to try. Nitro boys are building a block. There is a twin turbo build going on.
