I want the 272 because I need my trooper to go up mountain roads (I70 to Eisenhower tunnel), and I feel like the low-end torque is just fine. Do those of you running this cam have carbs?

I don't think the 272 is gonna enable the Trooper climb up to the tunnel that much better. That is one heck of a climb from either side for a 4-banger truck. Prolly best to just resign yourself to third gear and enjoy the scenery.

Thats probaly a good thing I would have just been confused any way.The cam does just what it is said to do, it does increase the power at the lowerend up thru the mid range. But much past 3500-3800 and it flattens out.My 2.6 has a Calmini header and a reconfigured ECM(Jet Performance). The one thing that I wasn't happy about was fuel milage offroad (14-16 down to 12-14). Just a side note I keep reading posts about cam timing with people saying not to use the balance pulley to set the cam because it may have slipped. Isn't that impossible to do becuase you have to have everything back together befor there is a mark for TDC? It may effect Ign. timing but not cam timing unless I missing something. Dave

I just got off the phone with delta and they said that I did not need to get valve adjusters as the mechanical rockers already had room to adjust for the grind on the cam. Are the valve adjusters only useful to get the most out of the cam?

The 272 was an utterly useless cam in my 1991 Amigo 2.6
Tried every option to make it work. From everything from 8* timing to 16* in a systematic order. The engine was a dog on bottom, and a dog on top. WOT was required at all times to have any sort of decent acceleration on highway. It might be usable with a bunch of extra compression, and full intake exhaust however in my opinion, anyone who says that its a "top end cam" is a damn fool. It was useless. Not to mention tons of Valve noise. Set at .007". double checked multiple times. I ran it about 8 months.
On a side note...
I'm selling a perfectly good Delta 272 camshaft!
(actually I'll probably turn it into a Lamp)
