I had a 89 Astro Van with a 4.3, the distributor was a smaller diameter with a remote mounted coil. I don't know but may be a low cost option for you.

Seth, I don't recall the list # on the Holley but I have it mounted so the secondary's are to the rear of the car. This one does use the metering plate instead of the block

Checking another view, I now see that. I guess you will need a smaller distributor -Seth

Seth, what do you get for a dist that would fit?

Also, what are the choices for starter ring gear replacement? With the dist I put together. the timing would go wacky and it would kick back and took a tooth off.
Oh ya, it runs!

Seems I have a cooling issue yet to cure. We're running a Speedway 24 inch double pass radiator and a Maradyne 15 inch puller fan, a 160* t-stat. With out being under load it will keep building temp. I checked the temp drop across the rad and find maybe 15*, I would say from this I just don't have enough air flow.
Is that what you guys would say as well?

Sadly.. absolutely..

PM'd you on the distributor. My intent is to run a Cosworth-Vega Nodular iron flywheel. It has a bolt pattern to match the 85 V6 crankshaft I have, and takes the Corvair clutch. I intend to run the Corvair starter in the stock position. (Or a Mini I have on the shelf.) I think you can still buy a replacement ring gear for the Corvair. The actual gear is the same on all Corvairs, stick or PG, as I recall. Clarks?

Craig replies:
The setup shown in your picture tells part of the tale. As shown, the fan only cools roughly 1/3 of the radiator. If you build a shroud that's maybe 1.5" deep and mount the fan on the shroud, then the fan will draw air through all of the radiator and roughly triple the cooling capacity.

I'd also suggest building a blocking panel between the front and back of the radiator. The panel would prevent pressurized air from the back of the fan from recirculating to the low-pressure area on the front of the radiator.

I do intend to separate and seal the front to the back on the radiator. I didn't expect that it would make enough difference running no load. I will be trying running it with the right muffler relocated temperately and see it that helps, If it does I'll need to figure what to do with the exhaust. I have been thinking on some shroud work but also didn't think that would make a lot of difference no load

Does the engine have a correct rotation water pump considering reverse rotation plus the change in belt drive?

Moving the radiator to the front is not allowed, not my car. If it was the radiator would be in the front with the engine right behind it!
I have double checked the water pump and it should be the proper rotation for this set up

Pull the heater by-pass hose to check flow

I see the fan is a puller. (I hope it can take radiant heat from the exhaust manifolds). What is the fan in the wheel well doing. Is that an oil cooler? Is it a pusher fan. Where is air coming in and where is it going? I am glad you have it running.

Both fans are pullers, I was thinking, maybe wrong, that the one on the radiator would be moving enough air that it would see radiator heat and blow the exhaust heat away. The small fan is pushing air towards the radiator, it's mounted on an engine/trans oil cooler.
I put an extension on the exhaust and had the muffler hung behind the car and that helped. Kinda figured it would some. I am thinking about an aluminum heat shield on the manifold.
I might try to fab up some kind of shroud for the fan as well.
I do need to solve the muffler heat issue some how.

On a slightly different note. How difficult should it be to get the shift cable in the trans right? It seems that I must not have it engaged, The axles are always rolling forwards, even with the shifter in reverse

pics and instructions are in our STICKY FAQ's under Powerglide

Any reason you cannot run a Big pipe Single on the other side...instead of duals?

I don't see much room to cross over the exhaust. I think I
need to spend more time laying under the car!

Find an "ovaled" pipe..

Look down about 1/4 of the page for RAW tubes..
