IF...
If a new aftermarket block was to be undertaken and you could only get one choice...what would it be?
1. A tall deck windsor (10.2 DH 351W) - perhaps the least costly option
2. A direct (but updated version of the 400 improved oiling, 4B mains,etc) - Big block hell housing pattern and all
3. a Cleveland style block (10.2 DH) with 351C bearing sizes and a small block bell housing pattern - improved oiling and 4b mains
4. A new and improved 9.2 deck C. (I know you can get a W in 9.2, but think about the aux items that would not mate up).
My vote is #3
why? I am guessing there are about 10 times the number of 400's around vs. 351C. Why would you not want another 50+ cubes all else being equal? The stroker potential is huge for the 10.2 block and it would be easy for some the bigger intake companies to simply transfer 351C manifold casting to the new DH. In most cases I can't image the additional 1 inch DH would pose a problem in engine bay fit. I look forward to your opinions...and thanks for playing.
My preference is a 400 block 10.297" deck height, with a small block bell housing pattern (AKA FMX block), or a dual bell housing pattern. This has the advantage of using the 351W stroker cranks that are available. Intake Manifolds have alway been a problem with the tall deck height 400, but maybe Edelbrock and Weiand will smell the coffee before CHI or offshore companies like Procomp drink it.

I agree. There has been a strong move to big inch small blocks for a good 10 years. We need a 10.297-10.302" DH Cleveland. Offer it with both small and big bell bolt patterns, 3-bolt and 2-bolt motor mounts, and a choice of 2.75 and 3" mains. Dart and World already offer their blocks in multiple DHs and 3 different main bearing sizes. A motor like this would appeal to not just the drag racers but also the off-road, mud racers, and pullers. You could easily get 488ci out of the block. The heads are on the market to support the displacement.
Diddo on a better 400 block, i'd have it so you can overbore more that what the stockers can, improve the oiling system a bit, dual bellhousing bolt pattern. If i had the cash i'd go this route and build the biggest displacement stroker i could out of it.

I've been pretty vocal about the benefits of producing a 400 style aftermarket block. With a max bore of 4.2 like the Dart/World blocks, the 400 style block could be built to 499ci. When I built my 400FMX, it was pretty easy to see that my 4" Eagle crank had more than enough room in the crank case. There was enough that a proper 4.5" forged crank would have fit. A 4.5" crank plus a 4.155" bore will give you a 488ci small block. Combine all this with your choice of 2.75 or 3" mains and you could have a heck of a power boat motor, drag motor, trailer tower, mud bogger, etc.,.... Another benefit is that whole thing would still be about 100lbs lighter than a 460 or the common 514ci stroker. Personally, I think a 499ci built with smaller 2.67" MOPAR mains and 1.88" rod journals would be a basis for a killer drag motor, especially in a light notchback Fox Mustang....and it would not be nearly as nose heavy as a 460 based Fox body drag car.
Someone is ready to build 351C blocks in Iron or Aluminum. They also mentioned 9.5" deck height blocks in the future. I have voiced my opinion in the past about 10.3" deck height, but apparently it fell on deaf ears.

I think the 9.2" Cleveland block will have to compete with the 9.2" Dart/World blocks. AND, this small run of Clevo blocks is going to cost a small fortune. The average guy is not going to spend more than he has to so he will just get a Dart/World block instead. However, a 10.3" block competes with no other small Ford. It would, IMHO, open up a different market. Really, why build a 427-454ci C/W style block when you could drop in a 488-499ci block that weighs pretty close to the same amount and is only slightly taller and wider than the 9.5" DH blocks? You will have a better rod/stroke ratio and less loading on the thrust side of the cylinder wall with the taller block. And besides, would you turn down extra cubic inches???
Thanks for your responses. I agree that the 9.2 Cleveland block would be redundant with the option of the 9.2W. How much are we willing to pay for a good 10.3? What do you think is a conservative estimate on annual sales of such an animial? I do some business with some casting operations...I will find out what the cost/break even would be.
as far as cost, well i can say i wouldn't pay to much more than what the dart/world 9.2/9.5 blocks go for, and honestly i don't know what those cost offhand, but if the profit margin is there i would have it the same approximate price as the 9.2/9.5 blocks with similar features. As far as how many would sell, well its all about the exposure it gets and the price, also having information for things like intakes, heads, etc that can be used with the block (mainly intakes as there aren't a lot of intakes avaible for a 10.3 block without the use of spacers) that would accompany the block when purchased.
my $.02, but then again i don't make or sell engine parts .
