Should be a good deal if it runs. Looks like you bought it from Meanassrx7

cdrad51: What are your plans for this motor??
That's exactly what I have in my 83 GSL, an 84 12A that was previously an automatic. From the way it runs, I would imagine my compression is still in the 100's. I guess the automatics sorta protect these engines.....

I'm gonna use it as a temporary replacement so I can get the streetported engine currently in the car rebuilt. Then I might keep it as a spare, or get it torn down, rebuilt and streetported.

Hey wacky- how's drivability (when fully warmed) with an IDA on a 12A stockport or streetport? Do they have a tendency to stumble at cruise like a dcoe?

It drives good. we use originally used 40 venturies in my bro's first stock engine, then switch to a 42 with the 12-A streetport, and now with the new stock engine again, we just left it alone. He loves the top end and a 75 idle jet helps a lot on take off from a full stop.
I havent played with the DCOE's progression hole but mainly on a IDA. extra progression hole (total of 3 on IDA), helps the transition from main jet to idle jet.
So picked up the engine yesterday. So far so good. Here's some pics:



Now to remove all the extra **** I don't need. Anybody need any smog ****, or A/C compressor? Nikki carb? exhaust manifold? intake manifold? beehive?

I wish I can find the time to install your engine as I got to work in my FB to get it ready for the annual run. hmmmmmmmmmmmm Juice it or boost it. Cant decide.
But hey, thats a good idea. Both stock 12-A and NoLuck's SE as well. Sterling Carb VS IDA VS FI. I will follow you guys with a video cam in my roll bars. then I will eat you guys alive.
