Timing chain install, which keyway?

[JackFish]

Planning to swap out the old chain for a new FSP double-roller tomorrow.
I'm looking for suggestions on choosing a keyway. Currently just a stock motor.
I do have a cam and new head but won't have the time to for that for a couple weeks yet. But I need to get this chain in because I drive about 250 highway miles a week at the moment.
Any and all suggestions and advice are appreciated.

If you want to do ot right, you don't want to just 'Choose a keyway'. You really should degree the cam properly.

Can't, no time. Gotta get the vehicle back on the road asap. Not taking the engine out. :smash:
And I'm not going to want to degree an old stock cam right at the moment when I have a 264/274 ready to go. In a few weeks I will degree that.
I'm just looking for some advice on this situation. Some "best guesses" from the experts.

8) set it either straight up, or with a nominal advance(2-4 degrees). i usually set them straight up myself.
