So I recently acquired a 76/77 13b. My plan was to bridgeport it and put it in my 79 rx7 but now I have changed plans and am possibly looking to move the engine on.

I have no history on it, I'm going to see if I can turn it over by hand to see if it has compression etc. Obviously compression vs no compression etc is a factor.

Any super ballpark ideas on how much it is worth to sell it on? I know 'its worth what someone is willing to pay for it' but a starting point would be great.

Thanks all.
