So you are just worried about drag and not much else?
If so then really no point going all out with big oil pumps, epic winged sumps etc. That's more for circuit. You are only running hard for 9 sec runs, it's a different ball game. Do the usual oil control modifications, ensure you don't sit on limiters and use a RB30 pump. (seems a typically good forumla)
Ensure the block is well grout filled - probably the most important part.
Put some good rods/pistons in there (and of course bolts). Port it to the heavens, put big cams & plenum on it - as at the end of the day loaded up on a transbrake, it's not going to matter all that much with a GT42 on it.
10k you should get away with it, but really for 150mph I think you'll be spending a tad more as it wi largely depend on how much you spend on the head more than the bottom end.
