I have used Indian Head Gasket Shellac for years with no problems, and it is inexpensive too.

Looking for a more modern, maybe better product, I'm going to try the Vibra-Tite 550 Core Plug Sealant on the next engine build.

I have run the Amsoil and Red Line gear oil in limited slip diffs without any friction modifier, even the shock proof stuff.
I have only run the Blue light weight shock proof in the 3.91:1 geared 8-3/4" (741 case) with limited-slip diff and didn't have any issues running mid 12s.
When I was...
I think my S60 Axle just said 500 street miles with the regular gear oil, then change the gear oil using regular or synthetic stuff.
If your racing, after break-in you might want to try the Red Line Shock Proof Gear Oil.

When I was in school in the 1980's and a IEEE member, we toured sandia national laboratories and they were showing us the lasers and and target chamber that the NIF is doing now.
That is where I asked why water (purified) was used as an insulator, it is self healing if the spark blows through...
Alot will depend on how it is tested (with or without accessories, mufflers, amount of tuning, fuel used, dyno correction factors, dyno acceleration rate and such.)
Looking at actual un-corrected power numbers here in Denver will show what happens when you don't have any air.
At about mile high...
I use the K&N filtered top lid in addition to the round filter, but I don't have a scoop or fresh air intake so the intake air temps are under hood temp, not ideal for performance.
Just saying that the air coming into the carb might not be ideal, and might be a limiting factor more than carb...
For the street the 750 is good because you usually are not driving at wide open throttle. If your racing a 950 would make a bit more power. This assumes that the air filter can handle it, or comparing both without an air filter.
Recently found out the difference between a Solar Day and Sidereal Day.
One 360-degree rotation of the Earth (Sidereal Day) takes about 23 Hours and 56 minutes.
A Solar Day, the Earth rotates almost 361 degrees (360.98561 degrees) in 24 hours.
The extra degree of rotation in the Solar Day is...
I'm too cheap to run nitrous. Refills can get expensive and depending on power level each run could cost $10-$20 or more in nitrous cost alone.
Most of the racers also carry extra bottles and bottle heaters adding to the total cost.
I could be off on prices, been out of the racing stuff for 10+...
I would at least try to stay with the factory mechanical fan with a radiator shroud. it is way simpler and less expensive.
Good quality electric cooling fans are expensive and pull a bunch of power which requires modification to the charging system.
Upgraded alternator and wiring, cooling fan...
