No 462625, but there is a 462624
Re check your crank # as I can't find that one at all.
1 = GM
M = Mexico, Toluca Engine Assembly
07 = July
27 = 27th day of month
5 = Last digit of year.. 1995 or 2005
H04 = I have no idea

Don't do the NOS fool stuff... If you are going to do it, do it correctly to prevent killing that nice crate motor. Single port dry shot (just NOS into the intake) isn't really worth the time or money to talk about.. so lets not. Best is a multi-port wet shot just before the head. Each cylinder gets hit with both NOS and more fuel to prevent the leaning out and overheating of the cyclinders. With this use a window switch to only allow a shot at predetermined RPMs so you can't shoot near redline and blow it. hooked to a WOT (wide open throttle switch). This way you need to be wide open and in the RPM window.. leave those perimeters and the shot stops. These kits can be bought from any of the big NOS stores online and even Summit Racing online. Follows the install instructions or have someone do it... When it is done right you can should be ok with upto 150 shots (an extra 150 HP) Have fun.
