Had a nice surprise today. Some photos of the actual B-7000 I knew early in my career. The photos were taken in 1964, 6 years before my time. It was orange with a blue logo. Later it became yellow with white doors withy a blue and black logo. Boy this brings back memories.

Your progress is impressive! I thought I was the only one building this motor a few weeks ago. However, I found your thread and was impressed. I joined modelcarsmag just recently prompted by my urge to get feedback on your (our) 702 WIPs.

landman, would you mind if I post photos of my motor for input/comparison?

By all means.The more, the merrier.We all can use additional ideas. I am especially curious as hoe you made the exhaust manifolds.

I'm still working on the block, heads, and valve covers. I was preparing to start scratching out the front water pump housing and was waiting for my membership approval to come through when I saw your progress. Here are some highlights of my progress.

And I think your valve covers are tight on.Made from flat stock & shaped.

I meant right on.

Coming along nicely,Donovan.What are you using?It almost looks like nailhead engines.

I used two V8s from the custom 70s Chevy van. I plan to build the van with the doghouse off and a visible 292 L6. The V8s were very low detail so it was toss or recycle.

How did you make your valve covers? They look more like 702's than mine which are narrowed 409's.

I glued up a scaled down valve cover seal to multiple strips of styrene. I cut and filled them in a staggered manner, removed the patterns and cemented the layers. Then I drilled and filed it to the shape it is now. I'm going to make just one and duplicate it in resin.

Made another water pump as the first one was too big.

Tried turning some three groove pulleys with a drill press and a hobby knife. Someone should buy me a mini lathe.

Installed the pulleys and the generator bracket.

Wow! WOW!! I wasn't even sure how I was going to proceed with the front of the motor, but I'm doubtful I'd done that before I'd seen it done...

First try at a generator.

Second try with a few mods.

Tried the masking tape method for the belts. it will work but they'll have to be narrower. Three belts, one for the generator and two for the air compressor.

Started on the third set of exhaust manifolds. This time with 2.5 mm stock. this should be more accurate.

I duplicated the styrene valve cover and cylinder head in resin. I think the easy part is almost done... Then I get to try the front of the motor. SIGH...

Pat, I didn't start with a commercial motor so I'm curious if I duplicate a more modern transmission mount area for the rear of my motor will it work (era correct dimensions)?

If you are duplicating that hot rod, you'll need to use a bell housing to fit whatever transmission you'll be using. In my case it will be a 5-speed GMC truck transmission.

Nice work on the valve covers Donovan! They match the originals perfectly with the extra dimples that the 409 valve covers don't have.

I kinda lucked out finding a picture of the valve cover seal on eBay and used it. I was going to use the same method as Pat until then. I don't think I've ever cut, trimmed, sanded, filed, etc. as I have on this one motor.

The new exhaust manifolds are better proportioned. A bit of tweaking here and there and they will do.
