Pulled the cam out and measured the lobes.
Stock cam lobe 1.388"
The best messurement we got was 1.383" and the worst 1.370"
Now the question is where should we have a cam regrind performed? I've heard good things about Delta Camshafts in Washington and have one of their cams in my MGB. I've also heard Isky is good for regrinds and hardens then "correctly" for used with hardened lifters.
Also, The head is at the shop being rebuilt and its up in the air if the head is recieving a light porting. We'll find this out Monday when we get ahold of the machine shop owner. Would it be better to stick with the stock grind or choose a slightly milder lift like a 260 duration?
One more thing, As BJ8s have Flat top pistons what is the most common way to boost compression to 9.5:1 or 10:1? The motor has fresh .030 over AE pistons so I don't think I will be changing pistons. Can the head be decked to achieve higher compression or are domed pistons a more common practice?
I know thats a lot of questions, but its a Saturday!
