It's another GREAT product for us Pontiac fanatics, and I applaud the Butlers for taking another leap forward!

The aluminum block in the pictures will not be a 4.6 bore block. A 4.6 block is a butler vision
at this point. Tom V.

Any confirmation?

[Half-Inch Stud]

Ahem, uhm, I uhm have a request;

I would like to see the new poncho blocks feature a dry deck. This means block coolant and head coolant remain separate, the head gasket remains dry, and fewer holes too. O-ring from block to head would take on a clean ability, without having the dual role of water sealing by virtue of a crush gashket.

Our blocks are ready to flow water front-to-back (traditional water pump-in, to freezeplug outlet). Our heads are ready for flow from back to front (yea, gazinta via backside end-face freezeplugs, and if ya like to continue reusing the water crossover for gazouta OK).

...did I mention a silicone-based coolant? Made local on Conshohoken PA.

I wish you were on our side several years ago HIS
when Marty and Mary Palbykin, Tom Earheart, and
I suggested the same thing to several people. It
did not fly then but it would be fairly routine
to tap and plug the few water holes in the AL
block Rodney is running.

I believe that presently the Butlers run:

1) into front of block

2) out of the rear of the block (Right block water
goes to rear of left head, Left block water goes to rear of right head.

3) Water from heads goes to thermostat/radiator.

Tom Wilhite runs two separate water systems for the heads vs block with temp control for each
system.

So how would you plumb the system you suggest?

How do others on the board plumb their water systems, dry deck, etc?

My plan at this time is to run a line from both heads into a Y and then a single line into the water crossover. It is my intention, as OMT has done, is to weld an extra piece of aluminum onto the back of the water cross over so that the single line will have a little more meat to attach to. Also, it looks like I will use a -12 braided hose.

[Brian Baker]

Tom, that sounds rather elaborate on the Butlers part. Why not just run the coolant out of the back of the block and directly into the back of the cylinder head that coresponds to the cylinder bank it's sitting on? Is there an advantage in running coolant from the left cylinder bank to the right cylinder head like the Butler's are doing?

And Mr. Wilhite's coolant system? Man, that sounds REAL elaborate.

[Tom Vaught]

Brian, I believe the Butler's crossed the lines from side to side of ease of plumbing. Aeroquip
fittings take up space and it is difficult to come right out of the block and back into the head on the same bank.

By crossing over the lines I think they had more
room for the fittings plus a short section of
aeroquip line. It was a packaging exercise for the Butlers. It was a coolant study for Tom
Wilhite to see if he could get more even cooling
for all cylinders. Tom V.

I think OMTs deal is of benefit because it takes
water from both the front and the rear of the heads and then on to the radiator. Some Chebby
guys use small lines just to remove air from the
rear of the heads.

[Brian Baker]

Understood on the AQP fittings and limited space available.

["Mike Kasparian]

HIS makes a good point.I would like to get heads and a block with out water holes.About 4 years ago i raised compression to 15:1 with copper gaskets and cylinder pressure would find its way to water holes.I decided to drill and tap all holes for plugs and reroute the water just as Tom
has described and it has worked great.Only problem i had was plugs coming out on heads in a couple spots because you can only get a few threads.I solved that problem by putting in longer plugs that bottomed out in head and getting copper gaskets with no water holes.I also
noticed on Rodney's turbo mtr that they welded holes up.I talked with Joe Z. and he had same problem. MK SR.

Well, I already have a IA block!

Seriously I hope they come out with more!!

An example of the Butler process, dry head also

[Skip Fix]

Saw a protoype block, RAIV intake and heard about new cast iron RAIV heads this weekend at the PSN from Jim. Some neat stuff! Will all have improvements over stock.

I guess I have a slight problem with allowing date codes on heads,intakes or exhaust manifolds to be cast in NEW products. I'm not a numbers matching kind of guy but that seems to make it hard to tell the real stuff for those that are.If its just for performance then they don;t need to be on them.

[SCOTT ESTERLE]

Date codes need to be there for Manufacturing process & to validate any warr if there is any.

[Lloyd-TX]

Scott:

What Skip is referring to is the fact that JBP will offer a limited number of these repro parts, date coded per customer request, for resto purposes.

[Brian Baker]

Correct me if I am wrong, but aren't R.A. IV heads void of any casting dates? Weren't they machined off in the process of building the valve spring seats or head bolt seats? I owned a pair of 722's and never saw a casting date on them anywhere.

[Steve C.]

He is going to offer customer specified cast in codes on the intake.

[Steve C.]

Correct me if I'm wrong but the line coming out of the side of the head on the above picture is a oil drain. There is another one coming out of the side toward in the rear. Rodney said the Titan pump really pushes alot of oil to the top... or something to that effect.

[Tom Vaught]

The line clearly visible in the photo is the oil drain for the driver's head. The two lines at the
back of the block are the water lines and you can see that they do "cross-over" from side to side.

The line shown at the top right of the photo had better not be a head oil drain as the loop in the
line is higher than the valve cover and will not
allow oil to drain from the valve cover/ head if that is what it is connected to.
