340 x-block vs. 410 stroker ?

I'm not 100% sure but I don't think that was the first start. I think the cam was already broken in. I was running a remote filter because the headers are so damn tight it kills my hands to change the filter on the block. I had a leak on the line for oil return to the block and couldn't get it stopped so I said piss on it and used a 90* adapter.

Noticed that you had the old carb on that start up too.

I think you're right it had been started before that one.
