TODAY is a Great Day to visit our Store and order the parts you need for your truck ! ! !
you'll notice for those flat tappet hydraulic cams I recommend the summit cams quite often. The brand names mean NOTHING. Edelbrock recently admitted to me they don't even make their own cams. They're just sticking the name on it. Hence why their technical data is contradictory and is flat out wrong in many circumstances. the guy on the other end of the phone many times will have never opened up and built an engine in their life. Listen to the guys here who have the experience with building LOTS of motors.
The XE274 will give you a nice chop. I have the XE268 and at idle in Park it has some lope but still idles fine at 850 or so RPM. When I drop it into Drive though and the revs drop to around 700, it really chops. Sounds like it wants to die and if the idle was any lower it probably would. When at a light with my foot on the brake it shakes the truck around and does this little surge every now and then. I quite like it. So the 274 you should not be unimpressed with as far as that goes.
