Who is familiar with "catcams'

[tn325i]

I was looking at this cam but don't know if it will work in my setup.

Catcam part #1300530

INTAKE EXHAUST

clearance [cl] 0.25mm 0.25mm

duration [0.1mm+cl] 296° 296°

duration [1.0mm+cl] 264° 264°

valve lift [cl=0] 12.50mm 12.50mm

cam lift 7.80mm 7.80mm

peak angle 105° 105°

timing [1.0mm+cl] 27/57° 57/27°

lift at TDC [cl=0] 4.50mm 4.50mm



I have an eta bottom end with the 731 euro head with the valves upped to "I" sized valves with dual springs. No other real internal mods.

will this work in my engine without having to make other changes ?

Any knowledgeable help is appreciated..

TIA,
Steve

Cat changed their check clearance a year or so ago. Same cam below measured @ 30 & 15 both are data from Cat. Never saved data from the big ass cam your looking @ :-) but that's huge for a 2.7 liter. Best I remember you're still 9:1 but do have stand alone. I'd back up a grind or two unless u plan on lots of RPM's. Some of the old race 2.5's used cams that big but were turning low 8K rpm's.

Thanks Mitch, Kinda what I was thinking but I just don't know the numbers very well to know what is usable.. I'm not going to be making those kind of changes to be using this one....:P

So does anyone know where I can find a cheaper used maybe 272 or 288 shrick or similar ?
