I wasn't going to post about my rebuild, but the thread this morning about the site being slow because of FB and not a lot going on changed my mind about it. So here it goes. I'll bring you all up to date and then post when things happen or when I can. By the way, I'm no where close to an expert on motors or rebuilds.

I started this project in Dec of 2016 thinking Iíd have it ready for Summer of 2017. Well, that just didnít happen. I guess most projects turn out that way. I pulled the motor because I had a lot of oil blowing out of the breathers. I tried 4 different set ups to alleviate the problem, but nothing worked so I figured it was a good time to freshen up the motor. I wasnít going to do much other then just freshen up and rebuild. Well, that changed quickly. Here's a picture before I pulled the motor.



My boy, who is 4 years old, and I pulled the motor and began tear down.  Upon inspection we found some pretty bad wear in some of the crankshaft main bearings and a hydraulic lifter that had a missing lifter cup retainer. Other than that, things looked pretty good.





My neighbor Rick, who is an Automotive Professor for our local college, has been helping me with the motor rebuild. We got the block over to his shop and got all the machine work completed. Upon inspection we found that the cylinders had already been bored .060 over. So, we honed them and got them to a finishing number of .061 over. Unbeknownst to me I had/have a 468.





Itís at this point that things began to change Rebuild wise. A friend of mine, who had rebuilt his motor the year before, had a set of Merlin heads sitting on the shelf. He told me that I could have them, free, for my build. I wasnít going to pass up the opportunity for some more bolt on HP. I picked up the heads and brought them over to the shop to begin work on them. We tore them down, cleaned them up and decided it would be good idea to have them sent out to be rebuilt by L&R Engines in Santa Fe Springs.

I'll continue on the next post.

Not sure why some of the photos went out of sequence, but I'll try and fix that in the future.  :sly:

Anyway, after sending the heads out it became aware to me that Iíd now have to change my tunnel ram. The new heads are rectangular port and that wouldnít work well with the oval port tunnel ram I had. I spoke with a friend of mine, who is also known as Jamminmon here on the forum. I was talking with him about the problem and he told me he had a lower for my tunnel ram that was rectangular port and would be willing to just swap them out. We made the swap, thanks John.



Now it was time to get back to work on the block. After hrs of grinding and cleaning up ruff edges and opening up oil drain backs we got to painting the block. Rick said if we're going to do it we might as well do a good job. He meant that we should hand paint the inside and out. Here's a pic of the inside paint job.



Now that I was going to be putting the different heads on the motor I decided that I would also go with a bigger cam shaft. I went with a hydraulic roller from Comp Cams. @.050 In. 242 Ex. 248, Lift - In. .566 Ex. .566 and a Lobe Sep of 112 degrees. I also ordered a set of Ultra-Pro Magnum Roller Rockers. Just a note, I had this information and gave the appropriate information given with the cam to L&R before the heads were rebuilt. As far as pistons and rods, we made the decision to reuse the connecting rods, but ordered a set of speed pro Dome pistons, which are what were on the motor before. We also ordered the rest of the gaskets and odds and ends that we needed at that point. The parts are in.

As far as the carburetors goes. I pulled the duel Holley 650's and brought them over to C&J Engineering in Santa Fe Springs. I gave them all the info for the motor and had them completely rebuilt. They are looking bitchen now!!  :thumbup:




 
The last couple months we haven't been able to do much on the motor. So, I've been cleaning up wiring and other stuff on the boat. I decided to add a droop and place diverter to the berkeley pump. My plan is to have the motor dyno tested and then have the pump gone through and matched to the motor. Of course that's more $$$ but, I know it's as important as the motor. Maybe more?





So this is basically where I'm at with the rebuild. We'll be getting back after it this week. I'll keep up posting as well as I can from here on out. Thanks for tagging along and I hope you enjoy.

Dang! Lots of good info there! Love the look of the pump. Super sexy. How much did the crab rebuilds set you back?  Did I miss an actual picture of the whole boat? Would like to see that. Hoping to be done by spring 2018?

Carb rebuild was $525. I'm hoping to be done by spring for sure. This has taken way longer then I wanted already and I don't want to miss another summer. Here is a pic of the boat the last time it was in the water. It's an 81 Bahner.

So I  had the same  setup  as you have on your pump earlier this year and it rode really wet.
Wedges didn't help!
Once you get it back on the water and aren't happy with  how it rides, hit up Tim place in la habra he'll get ur shit set up rite
Just .02

Bitchin dude! Derek at L&R Engines and John Moreland from C&J Engineering are both good friends of mine and helped me out a lot with my twin turbo motor. Great dudes for sure. Can't wait to see your boat back on the water with all the upgrades. Thanks for sharing for the small audience that still frequents the app and refuses to partake in the Facebook page!

So what did Tim do to your boat to change the set up. 
 He already has droop and diverter
