Good to know.

OH, and the rear is a 3.70. Would prefer something lower for the M21, but beggars can't be choosers, right?

1970 LT-1 New Acquisition.
 
Lynn,

You will really enjoy the high compression solid lifter LT-1, the close ratio M-21 and the 3:70 gear, that's a perfect match in my opinion. My 67 L-79 roadster was a M-21 and a 3:70 gear car and I loved it. Good luck with your new find, what a Neat car!

Bill

Looks good.

I may need pics of the ignition wiring for the 1970 TI set up. My understanding is that there is a ballast resistor involved. This car has one, but I have no idea if it is the original, or something the PO added when he converted to points dist.

Ordered the shipper report yesterday from NCRS. Figured that would be the first step in trying to locate the original owner. Without a tank sticker, I would like to be able to locate some documentation on the car, although as far as being an LT-1, I believe the engine and other components speak for themselves. Should be able to get clear pics of the engine stamp this weekend.

"My understanding is that there is a ballast resistor involved"...I think the harness has resistance wiring built into it. I've never noticed a resistor on my car (71 LT-1).

There is information and wiring diagrams on the internet, but some of these are for a add on kit that GM sold.

I used a replacement board from these people, car starts and idles better then it did before (old board got smoked). Been several years with no problems.

These are great cars. This is one I had until about 8 years ago. Sold it to my cousin.

In fact, I just bought another one that I'll share soon

Been going through the original engine. Just to be safe, having things checked out by a machine shop.

In the meantime, decided to get the 283 that is sitting in it running well enough to drive while I restore the extra frame, etc. Pulled the distributor and there was about 1/16 inch play in the shaft... not end play, mind you, but side to side. Amazing that it even ran. Put it in my distributor machine and the dwell would vary from 22 degrees to 35 degrees, bouncing back and forth. Got an old distributor with a 532 cam, and set it up with a B28 vac advance. In the meantime, the fuel pump quit completely.

Ordered a fuel pump and an oil filter (66 283 has a canister type). Fuel pump woes here:

Pulled the new fuel pump off and just bypassed it with a low pressure electric pump on it. Put a block off plate on where the fuel pump goes. Still ran very rich, with gas dripping off the boosters. Floats were way high. Got things adjusted and it really doesn't run too bad. Kind of gutless. Drove it a few miles, then decided I needed pics of it with its little brother, the 69 Opel GT.

I always say...the internal combustion engine is one forgiving technology.
