The only positive way to check if the oil pump is working and therefore there is correct oil pressure is to temporary install a non-electrical oil pressure gauge that uses a small copper tubing to sample the oil/pressure and drive a needle on the gauge. Depending on temperature, idle should register about 20+psi. Having done this and confirmed that indeed there is sufficient oil pressure then it may simply be a defective oil sending unit. Otherwise, no or low oil pressure at idle is an indicator that the engine needs to be opened up again.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

When looking for a "faster" transmission you need to check the actual individual gear ratios of each gearbox and match anticipated rpm to available peak torque of the engine. This gets a bit complicated but likely if you speak with anyone who drag races a similar vehicle they can hook you up with charts & formulas. As far as top speed goes, that's all determined by your engine and differential/tire combination as all units are 1:1 in fourth gear (fifth gear is overdrive and may give you slightly more top end) For a street car, there are far easier ways of wringing out a bit more performance.

A dirty air cleaner will cause an engine to use lots of fuel and still appear to run fine especally in cold weather. If you have not changed your air cleaner in sometime do so and note the difference.
Also a sticking EGR valve i.e stuck closed at highway speeds / passing / starts and stops can rob you of fuel economy.
If you know any half way good backyard auto mechanics they will know how to test an EGR valve with an external vacuum hose.
Thanks for using FixYa!
