I would like to know has anyone use the comp cam XFI 280, the one with the .576 lift RPM rang from 2000 to 6000, if so tell me what you think of it vs the XFI 268 with the .570 lift RPM range 1800 - 5800 i want to use one of these cams but undesided. 350 bored .030, HSR, 700R4

 

I'm running a XFI 292 and like it, but the power is all up high so yuor gunna need a stall and gears.

For a daily driver I'd suggest the 268 over the 280, give you abit more low rpm power for cruising around town

 

Its a big cam for a 350, so you better have good heads and a higher stall converter. Dont forget the custom chip tuning.

 

I have the xfi280 cam, although it is a flat tappet.

The power is up top for sure. But I have a 3200 stall and 3.73 gears.

When I have the engine below the sweet spot, once it hits 4500, it's awesome!

Make sure you have a good intake for that cam, it wouldn't work on a tpi.

I had a hard time deciding between the 268 and the 280 cam. On desktop dyno, the difference was about 15hp but the 280 cam made the power 500rpm higher, same with the tq, higher but it was 500rpm higher.

Hope that helps!

 

It works on a TPI.

But, I'd go with the 268 for a daily driver with a 350.

 

Thanks guys, i knew someone here was running those cams, i am going with the 268 for daily driver.
