i'd search google for 248/240 cam and go to the nico thread that's about 10 pages first.

The 248/248 setup needs adjustments to the timing according to those that use them...however; some of those same people told me certain settings with my 248/232 setup and apparently didn't actually test it (although in posts they have said they did).

When I advanced my 248 cam on intake 2.5 degrees as was stated I lost 30+ hp. I now have it retarded 2.5 degrees and my power feels much much better.

I need to get it back to the dyno to verify.

Greaser has used the 248/248 setup I believe and has dynos on it. Alot is on FreshAlloy which is down right now.

The other setup is the 240/248 setup running -7 and -5 respectively on the cams...a guy named Tre did this along with SAFC and supporting mods and pulled a damn 14.9 in the 1/4 mile.

niice..yo what and easy way to install the cams??what color is the 248 cam???

alkemyst

the 248 comes in green and orange, depending on intake or exhaust.

This is all very basic knowledge though, I would suggest as I said and google the 248/240 cam thread and start reading there.

how did u install ya cams??did u put the cam in 1st the put the gears on or no??

It would have made no sense not to put the gear in at the same time even if I was going to straight up timing. I didn't not touch my exhaust cam.

Regardless though, with these gears they have to be removed anytime a timing change happens.
