I love the triple taillights! They look great on EMs.

All those taillights are actually backup housings that I reworked to be taillights. I couldn't find enough taillight housings in good condition and didn't like the socket sticking into the engine bay

Guys, I dug out all my 4.3L stuff this afternoon. some of it goes over to the machine shop tomorrow. I want them to do a trial assembly of the block/cam/crank assembly. The reversing of the motor changes the cam drive to a single gear drive. When I had the machine work done, and new 4-bolt mains done, the centerline of the crank moved just a little toward the cam. (line honing) It became a little tight during rotation. I had the gears "worked on" back east. I am hopeful that they will be free enough for complete assembly. If so, I will do the full assembly. It should be a fun project for this summer. The intent is an autocross/track car.

I guess I wouldn't have thought about the lash changing with the mains getting redone. Kinda like not thinking about crank seals being directional till this build.

Seth, are you intending for a front mounted radiator?

Oh yeah - Front radiator. Even though this motor is all-aluminum, I want to shift as much weight forward as I can for balance. I already have a front oil cooler and filter. More plumbing to be added.

We got the transmission back this last week. Bolted everything together and was planing to bend up transmission lines but the shop didn't get the pump housing drilled for the cooler fittings as I asked. I guess it's another stand still till that gets done. I think I'll get the mower ready instead

Thank you

Yes it did!
I think I'm going to end up doing the coolder port modification, It looks to me that there is a passage between where the ports end up that should be plugged for a full flow cooler. I'll see what I come up with

Well, tonight I got after the oil cooler in the Powerglide. Every time I do much with this transmission, I get more disappointed in the corvair shop that I brought the trans to.
How's this look?

Should do it... you did block the one passage?

Sure did, I taped the pump housing with 1/4 pipe threads and installed a brass plug, cut and filed it down flush.

Craig replies: All-aluminum??? I thought the only aluminum 4.3 blocks were GM Performance (racing) parts? How & where did you find one? My local machinist had one from an overheated and seized race motor and still wanted big money for it.

Seth - update on the aluminum V6. I received word that the "massaged" gear to gear clearance is such that I can go ahead with the assembly of the V6. Racyr - How thick is your adapter? In other words, what is the distance from the face of the block casting to the face of the differential. 4-5-6 inches? yellow in the photo?

It looks like 5 3/4 inches

Thank You - The reason I asked is that my KEP adapter is only 4.75" thick. It does look thinner than the "MID style" one. I will have to slide it up onto the block and see the "mounting face of the crank to the diff face" dimension to see how close it is to the Corvair. This will influence input shaft contact and flywheel/clutch/throwout face locations. It does mean the engine will be an inch further forward in the chassis. I am hoping to avoid cutting the rear cross-member for water pump clearance. Since my install - if it ever happens - will be in a race car, I may be able to use different motor mounts, with almost no rubber. Still working on that! And I still have those darn Syclone/typhoon parts laying around. Hmmm.

We have reasonable clearance with this adapter. The pulley does overhang the rear crossmember some but there is room to get the belt under it. We did have a spacer/adapter made for the crank flange to the Corvair flex plate
