Adding to the info:

1) The 4-cylinder block is designed for midget racing with a provision for an in-and-out box, not a traditional Chevy bell housing. Furthermore, there is no provision for an internal oil pump so an external pump (dry or wet sump) is required. In addition, I believe there is no provision for a distributor and a crank trigger is required.

Scott has a couple (?) of raw cast 4-cylinder blocks in hand. I'm not clear whether he has patterns for a 6-cylinder block or not. I know the (longer term) plan is to provide both 4- and 6-cylinder blocks with water jackets and provisions for a standard bell housing and starter. Don't know how/if Scott will deal with the distributor issue. (By the way, Joe Hunt can make up one of there "magneto look" HEI distributors for most inline 4s and 6s. They're not cheap but they work well and sure look nice!).

2) The 4- and 6-cylinder heads will be offered as either solid (race only) or water jacketed. In another thread, Scott indicated that he might offer an option of providing a bare, but fully machined head to allow the buyer to finish out the head with their own choice of components as dictated by the intended use.

Obviously, the new heads are not cross-flow but similar to the Sissell/Kirby head with the exception that Scott's heads have rectangular intake ports while the Sissell/Kirby head have round intake ports.

3) The photos show both 4- and 6-cylinder port injectors and, as already noted, one of the two front covers provides mounting for a typical Hilborn or Enderle mechanical fuel pump. I believe there is also the provision to drive a water pump off one of the front covers (though perhaps not both the water and fuel pump - not clear on that).

In exchanging email with Scott, I suggested that he might consider modifying these patterns to include EFI injector bosses for customers that want to go that direction. Of course, these new heads will bolt up to the OEM 250/292 blocks.

4) One of Scott's tasks (I'm assuming early on) will be to revise the tooling to replace the Deppe and Duggan branding with his own Marshall brand.

5) Finally, though not a part of this group of products, Scott and I have been working on a new intake system for the good old siamese port head. The plan is to develop an intake similar to the early Corvette "Blue Flame" setup that will use three side-draft Carter YH carbs. Should be "old school cool". We'll keep you posted on the progress of this project.

The above is somewhat preliminary and, if I've got anything wrong, I'm sure Scott or others will make the necessary corrections.
