Back around 1974 I was at Barnett Race Cars in Atlanta with a buddy. One of the Barnett's (don't remember now which one) was welding chrome moly tubes into a 400 block and turning it into a Hemi block just like the picture above. the pistons were considerably shorter and he used a shorter stroke with the long rods to get a 396 cu inch Hemi for the lighter car and lighter rotating assembly.

Dave Koffel and Wally Dyck ran a B dragster with a 383 and Hemi heads in Comp in the late 80's I believe it was the #1 qualifier At Indy. This was right before the B-1 head era. I believe a friend of mine still has the block and heads.

So what's the fesability of building one of these?

Seems like the downfall is a heavy dome piston, custom rods and figuring out an intake.

Mike had Tom Hanners old parts. 400 block. The deck on the block in the old pics was decked quite a bit. Look at where the water pump bolt holes are in relation to the deck. I have a 9.700 deck KB block that came from the B1 TS pro stock era. Building a 484 B1 twin turbo motor out of it.

Would be easier due to that Stage V wedge pattern head still being available.

The Super Stock Hemi pistons being run today are in the lower 500 gram range, so piston weight wouldn't be an big issue. BBC rods are plentiful, and a std. deck intake can be modified (like seen in the earlier pics).

Funny story I just remembered about Hagen - the NHRA engine set back rule was that the front spark plug hole centerline could not be further back than the front spindle centerline. NHRA thought that the motor was set back too far - so off comes the valve cover, flip the plug hole cover and tube 180 degrees, put the spark plug in the other farther forward hole and back together.

Didn't know they made these. Stage V low deck hemi inline dual four manifold.

Stage V must have made a run of the wedge pattern blocks? I wonder if the lack of new hemi blocks has anything to do with it , assuming they did ?

The picture of the block Joel posted also shows half round stock welded in where the Exh push rod intrude into the edge of the deck.

I wonder what they did to the main caps ?

I wonder why the oil pan rail is milled on the drivers side? Center image.

Probably to get rid of the lip...enhancing oil drainback. Also slightly helping w/ windage too I'd guess.

watch this low deck build

I have one that was sold t my home town t Wally Dyck of Winnipeg Manitoba Canada raced fr many years with it fr mopar.I have the heads and crank too. 1966 K alum hemi heads highly ported by Mullins and flowed 420 int and 260 exh. Email ur storys and pics t me Blown526@icloud.com thx

I have a 400 low deck original hemi block that wally dyck bought and ran fr several years.

I have one still thx

A 7 year old thread has been brought back to life?!?!

Mike had a 400 block. His brother Tim and he also had some of Hanner's engine parts. Unfortunately Mike passed from Cancer in 2021.

Any of you remember a magazine article from like 30yrs ago where a guy was building low deck hemis by machining flats in the valley and using epoxy and bolts to add blocks for the inner studs ? I’m thinking his name was Holt ???

....and????

Was the last Mopar Wing Car in 1971 at Daytona a destroked 305 Hemi or a SBM?
Since Min weight back then was 3600? lbs, weight was not much of an issue.

I'm pretty sure the Dick Brooks Daytona ran a Keith Black prepped 305 (destroked 340) engine. The smallest Hemi I remember was the 366 Hemi with the 3.21" stroke crank and stupid long rods (7.3"). They were more successful in the Mopar Missile with the D5 heads as I recall.
