i can say that in the kind of racing i do (weight to cid) you should be able to build a more competitive engine for the reasons above (lite, less rotating mass, stronger. we dont use huge cid engines and spin the little ones to the moon.
I to would like to see a low deck cast block, would order one right now.

why do we need a decent aftermarket low block? because even good stock blocks can only handle so much power for so long before they fail & destroy all your good add-on parts. low blocks might have a cube limit but they're in the right ballpark for common as muck -1,sr & eddy heads in terms of flowability/cubes. both my previous 400/451's died from block failure. even a half filled block didn't stop my last stock block from doing a horizontal split in the bore hydraulicing that chamber & cracking the head. i waited for months on the story mike @ MM telling me Bulldog were making an iron low deck. i gave up waiting & bought an Indymaxx, it blew my budget at the time but i needed something better than another stocker which i knew would eventually fail. sure i was expecting big numbers from my build but don't we all? my 451 in my 'cuda was easier to work on than my mates 440 & junky old hooker headers would fit easily & could be moved over for head retorquing without too much profanity. personaly i feel low decks are great sleeper motors as the ch*v & f*rd boys don't know what they're up against & they become rather sheepish when you take them out with what they think is a small block. a certain Mr Mustang with a 428 hasn't been back since a 340 'cuda put him on the trailer lol.

I'm in the same boat as Andy, I need a low deck for my application. I know my factory block is a ticking time bomb and an alloy block is not in the budget for me. A cast iron low deck racing block at a resonable cost would fit my needs to a T. I hope you guys can make it happen.

I've lately heard of people talking about wanting low deck blocks but when it comes RIGHT down to it are they really going to buy them? Some will for sure but once that first set of go getters are out of the way is the market still there for years to come.... I'm not so sure.

From what i have read and heard your KP blocks are amazing pieces of work and Koffles would back them, if they weren't!

This might be a silly idea but someone said they were gonna try and cut the deck height of your RB block to a low deck. Would it be easier to just change something on your already good RB to allow them to be cut down to Low decks if the customer wants? I'm probably missing something that wont allow for this.

Another good point is alot of people are wanting to go BIGGER and BIGGER cause its getting cheaper to build 540-572ci engines. Maybe look at what the main cubes were in engines five ten years ago and look where they are now.... and then guess where they might be in 5 years. In my mind i think we would be seeing more 572ci then 500's. and we will be turning the BIG cubes just like the 500ci's. But that's just my guess. I know the 600-650ci around here are running 8000-8500rpm for a good 20 seconds every run making 30-40 paces a summer. and the NTPA boys are doing closer to 100 hooks a season. (they all use iron blocks)

I guess what my little point is as technology changes were trying to get the BIG cubes to make the same cube to hp ratio as the smaller ones and its slowly catching up.

Maybe the best bet would be is ask what Koffles or Muscle Motors would like to see.

You know what i would like to see (4.840bs)

You are absolutely right Diablo some people are tire kickers.It would seem that all you would have to do to a RB block to make it a Low Deck is mill the deck down, but its just not the case, for example the stock for the head bolts would be one thing the biggest diffrence though however is how your tooling is set up.Sorry about not having the 4.84 in production yet, but you know how the story goes one thing at a time.

Thanks for talking us up!!!

iron,
1= i think more week in and week out racers would like it better (heat soak, valve adj wont change as much with engine temp changes, more consistant)
2= cost
3= tighter valve to piston, piston to head
4= more hp
and a few other things

Bear, I am building a 512 right now using a 72 400 block. I did a partial fill on it. I have a BCR girdle kit w/ aluminum caps. So, let's see, $300.00 for the block.
$100.00 to clean it.
$100.00 to Mag it.
$ 75.00 to fill it.
$600.00 for girdle kit.
$4 or 500.00 to install girdle kit
?????? Machine work ???????




I will say approx. $2,000.00 into a stock block which I will still have to worry about. I will pay the extra money for your block. A 4.5 bore. Better oiling. Stronger mains. Stronger block all around.

I will place the order right now if you want to take pre-orders. I think you will find the market for the low deck is there, Your quality seems to be outstanding. If you do the same with the low deck you should sell some blocks.

---

You bring up some very good points my friend.We still need to do some tweeking to the patterns but it is doable.We do not want to take ANYONES money until we actally have the product, even though it is EXTREMLY tempting.Just getting some extra assurance that people will in fact buy them means a world of difference!
We really appreciate the comments and hope to gain your business!!!

BIG BEAR, if you did make the (IRON) low deck how much heavier would be than the factory low deck block? hopefully not much.

---

Until we actually machine one to completion its kind of hard to say.But whatever the differance,I would have to believe the strenght gained and the capabilities of the block would exceed the weight difference! And if we end up casting the way we intend to, we will end up with a much more substantial deck!

Guy's, You have to realise that you can't have all the options without a weight penalty.Thicker bores dual pattern belhousings steel billet main caps etc. add weight. Marty i feel you and steve have done a great job to get where we are now.For the foks out there we should have the first al block on the dyno before christmas.We will post pic's and results when done here on martys site and on our site.I can tell you that the al block with sleeves and billet caps weigh in at 132 lbs.We are very pumped with the project.Thanks,Scott

Thanks alot Scott, we really appreciate that coming from you! It's good to hear that you are making progress on that engine.Keep in mind the production blocks may differ slightly just as the iron one did.
