im replacing my 86 307 with an 72 350 olds engine i orderd an edlebrock cam from jegs with 280/290 dur and 448/472 lift. will this cam cause a problem with a stock rebuilt 200 tranny? and do any of you guys have any likely problems i might run into?

Is your stock trans a 200C three speed or the 200-4R four speed? The 200C is essentially the Vega trans and even a stock 350 will likely shred it. The 200-4R needs specific internal upgrades to handle the 350 and a "stock" rebuild will likely not do the trick. Run it until it breaks then get a stronger one built.

You might try reading these two boards devoted to Olds:

realoldspower.com
oldspower.com

Search on "cam" or "204/214" and you will probably get a lot of hits.
A cam that is 204/214 @ 0.050" tappet lift is not going to be 280/290 advertised. It's going to be more like 260/270 advertised. An Olds cam with 280/290 advertised will be in the neighborhood of 224/234 @ 0.050" and will be way too much for a 8:1 motor.

Here's a cam that would work for a 8:1 motor. Read the description in the upper right hand section of the card and note the recommended static compression ratio......

Based on the lift specs I think he is talking about Edelbrock cam #3712 with the following published specs:
advertised duration: 280/290
.050 duration: 204/214
lift at valve: .448/.472
intake centerline: 106*
lobe separation: 114*

It is referred to as a generic RV cam for low end torque; same cam is made by Melling and other companies.

The original cam in the early 70's olds were 186/202, .400/.400 with 109* LSA; so the crane cam is in between the original cam and the Edelbrock 204/214.

On the Olds boards, the 204/214 cam consistently gets good reviews for these low compression engines.

I have never installed a cam myself, but my 1971 Olds 350 has this Edelbrock cam and I think it is fine. My performance is not quite want I want yet, but I think it is due to carb setup, not the cam.

And the opinion that the hotter cams such as 214/224 are not suitable for a low compression engine is consistent with what I have read elsewhere.
