I ended up with only one good block, the other was junk.  Sorry bro. I've still got a crank I'll sell you cheap.

PROGRESS!!!!! in the right direction I hope.

I picked up the block from this new machine shop I'm trying out...prelimary measurements agree with what they said they did...so we're looking good.  My old shop said I was already 0.005 outta the hole and that's why they didn't deck it.  I picked it up and measured it up at 0.010-.011" in the hole.  The new shop took off 0.008...only had to go that far because it was twisted...which should leave me about 0.002-0.003 in the hole.  Perfect.

I spent the evening cleaning the block...pressure washed it, blow dried it, chased every hole in the block, glyptol'd the inside and painted the outside, then a bunch of passes over the machined surfaces with laquer thinner until the rags came out clean...then more compressed air...I think it's clean.  I cleaned up the oil pump supply passage in the rear cap...dunno if it'll do any good but it can't hurt.  After I was happy with the cleanliness, I set the crank in it.  I already had the mains and thrust measured up so I didn't do it again. 

I picked up a gram scale from Harbor Freight tonight to match balance all the pistons....and every one of them came in at 708 grams w/ the pin.  i know the scale works cuz I threw a dollar bill on it and it went up to 709 grams.  SRP did good.

I wanted to start gapping the rings, but I couldn't find the squaring tool I made when I put the last BBC together...I think I might have made a nozzle insert out of it. Oh well.  I made a new one on the lathe out of the front bearing retainer from GeneralLee's blowed up bayjet pump.  Pretty nice piece of billet, but it was thrashed from the bearing blowing up so I figured what the hell.

Gotta spend some time with Momma for the rest of the night.

Got all the rings gapped tonight...only screwed up one of 'em...but it's the second ring, and it's only 0.002" big.  I probably should care...but I really don't at this point.  I talked to Chris Straub about the 2 cams I had and my combo and he picked one of them but told me to set it up advanced 2°, snug up the exhaust and loosen up on the intakes...took me 2 tries to get the cam degreed in right.



...and my super bitchin custom ring squaring tool....



Sinks the ring 1 inch down the hole.

All the pistons are in...I set the main bearings at 0.0032-0.0035 and while I was advised to run a little looser on the rods, the bearings that were in the last motor looked perfect after much abuse being set at 0.0018 - .002, so I used standard Clevite HN bearings and set it at 0.002-.0022.  I had do buff the plating off of the back of a couple shells to bring them in but it worked out well. 



The motor in the new boat came with a nice aluminum timing cover, so I wanted to use that.  It won't fit with my old cam button unless I face it down a bit...I can't find where I put the cam button that came out of that motor...so tomorrow morning I'm cleaning the garage.  It's getting a bit outta hand in there, hopefully in cleaning I'll find the other cam button. 

Shootin for labor day.

Fought with rocker geometry this morning for a little bit...but I got past that.  Buttoned it all up and the motor is in. 

I'm using the same mounts...but I drilled out the plate bolt hole to 3/8.  You guys that use the little angle brackets...what size bolts are you using?  I'm ending up with 2 5/16-18 bolts holding each block to the rails and one 3/8-16 bolt holding the plate to the block...is this sufficient?

Depends on the bolts....As the bolts size goes up, the hole size does too....It's a balancing act between the material being bolted and the composition of the hardware... ;)

Cadmium plated grade 8 for hex headed bolts, black oxide allens should be more than enough bolt, but the mated surfaces must be extremely flush with each other....

I'm using stainless hardware...all the mounting surfaces mate nicely...and are angled correctly.  I'm using some backing plates where required.  I'll run it and see what happens...maybe throw a safety chain on in just in case...cuz I'm a hack.

I've got a new delimna....I've got dominator pump....and 3 transom adapters for a berkeley pumps, where are too small to fit over my bowl.  I would really like to use transom plates instead of the stupid adapter so that I don't have to tear shit apart should I have to remove the bowl, but the pod is just long enough where the plates would touch the heads of the bowl bolts.  It looks like I'm cutting down the pod about 4 inches.  I'm gonna try to do it such that I can reuse the plates off of the old boat.................and I'm gonna try and leave the intake in.  This should be fun.  More pictures tonight.

Too late, I already cut half the pod off.  

The reason I did it this way is because:

If I need to pull the bowl to dig out rocks or whatever, I don't need to take anything apart...just remove the exposed bowl bolts and I'm in.  Maybe I got spoiled on the old boat with servicability.  It took me about an hour or so to get the transom adapter off this thing when I was tearing it apart...all the cables went through it and none of them sealed for shit, but were somehow stuck.  The damn steer tube took me the better part of 30 minutes to get out.  Screw that.  One thing I can't friggen stand about a lot of boats and the way they are assembled is the lack of serviceability.  I try to use captive nuts wherever I can on through bolts and I try to make it so I can take the whole damn thing apart in less than an hour if I have to....makes repairs at the river a lot easier in the heat.

I took about 6 inches off the pod...it's about even with the cav plates now.  There were also a couple cracks that I saw through the paint....and I'm glad I started grinding because they went all way through...about 8 inches long each where the pod meets the transom.  The grinder went right through, so they were some thin spots...one of them is a hole about 2 inches by 9 inches now, the other is a bit smaller.  I'll fix those too.  i've got it mostly prepped and hopefully I can get the rest of the prep done tomorrow and glass the sumbitch back together.  I'm cutting a bigger access hole in top of the pod and glassing in a recessed lip so the aluminum cover sits flush with the surface...it look cool in my head, we'll see how it turns out.

Glassing the pod back together.





I cut the flanged part off of the back and then took a 4ish inch section of out it, and I'm glassing the flanged part back on.  During my prep, the flange broke into about 4 pieces.  I had to grind out a bunch of bad repair work.  I held the pieces back onto the boat with masking tape and shimmed it close to where it needs to end up...then used some short pieces of glass to stick it all together.  This is as far as I got last night.  Tonight, the plan is to do 2 more layers of glass on the inside, then once that kicks, grind the outside again and do 2 layers on that.  I'll then prep all that stuff and do a filler coat and start blocking.  Total should be 4 layers of mat.

It's black.  Black comes in spray cans....I'm good.

Need some help on the transom hardware.  I'm making some plates to go between the pads and the transom, and I'm refinishing the cav plates, ride plate, transom plates, and bowl saddle....

Pump will be painted black.

Should I...

polish (I'd have to continually repolish...which sucks)
anodize clear
anodize red (would look good in the beginning but when it fades, would be pink)
anodize gold (might look good since there is yellow on the boat, and when it fades it's still gold)
anodize black (would look good in the beginning but turn purple when it fades)
powdercoat black (might chip when hardware is installed)

I'm glad everything worked out with the new machine shop. It's amazing how many shops can't do the most basic machine work. If you ever gap a ring a tad on the big side just install it in the lean hole. It depends which manifold is being used. Then you won't feel so bad being a .001-.002 off!

Dart manifold...but, the heads are on, and they probably won't come off until I crash it, so it's a moot point. 

What color should I do the transom hardware?  Amazingly, that's my primary concern right now...

I hate fiberglass work.  Now that I've got the structure down, I'm trying to true everything up.  It's proving to be a pain in the ass. 

Oh well, it'll at least be straight when I'm done.

Ok, Pod is done...still need to color sand and polish, but it came out decent. 




...been working on the transom plates between diaper changes.  Junior came out and helped (sat in his swing in the garage)  Got the transom plates more or less done tonight....they're fitted to the pump and rough cut to the shape of the pod.  Just need to drill/countersink all my holes, bolt it on, and I'm gonna try goin after it with a trim router and a roundover bit to clean up the edges.  I'll try a piece of scrap first to see how it works. 

Here's a couple pics from tonight.  I also machined the seam to make a 1" lap joint...probably not necessary, but I think it's cool.



The lap joint



I made a rough pattern out of cardboard, then transfered it to 3/16" plate and cut it out.  I spent about an hour with various die grinders getting it within 1/16", then traced that and cut out the other side....that one didn't take as long to fit.  Did as much cutting as I could on my bandsaw, but it's only got a 4" throat so I had to do some work with a jigsaw.  Machining was done on my little mill....amazingly, it came out damn near perfect considering all my measurements were from crappy reference points. 

I think I'm gonna powdercoat 'em black.

 Looks good Pat.  I like the lap joint, thats going to looks really clean that way.  When I did the ones for my old boat I didnt think of that and had to use a 3rd piece inside the plates to bolt them together.
