That's a great cam for a stock heads and converter. Also going to give you low end torque, no need for dual springs. If you did it in a roller set up, better mpg, less parastitic hp loss, netting more power to the wheels, and spin up the rpm quicker. I think I mentioned everyone is going to have their own opinions and what they like and want. This one here is a good happy medium on a 110 lobe center good for low to mid range torque. That's what you'll want in a truck. Trucks are heavier, likley to be towing or pulling weight so that is where you want your power band. Even in OEM specs right off the showroom floor, Trucks have differant cam grinds than cars for this reason. If you were running a Chevy Vega that is light weight, you could go with mid to top end range cam, but in a truck, you gotta have a grind spec that will get the weight moving off the line. Just keep that in mind when deciding and taking everyone's opinion account. Some people are going to tell you what worked for good them in the past. Like I said, that may have been in a Vega. Put that same cam in a truck, and you don't even start making power til half track to get the rpm up in the power band unless you're running a 4,000 stall and by the time you get to 4,000 you're going to run out of gear at the end of the track. Just sayin, I see your frustration, but don't give up on it. And if you just want to make a decision and get off the fence for purpose of making forward progress, go with HE268 grind in a roller if you want. Personally, you got your Square that's basically stock with a little performance mods, I think it would be cool, to have the 65 a little peppier than the square. Obviously the 65 is a toy. Its not going to be your daily driver, or your back up transportation like the Square, so WTH, play with it a bit. Put a little muscle in it and play with it. You'll break parts, but so what. That's part of the fun and the learning process. Each time you break, you make it a little stonger til eventually it quits breaking. You're weak link in the 65 I thin in the 65 is going to be rear end and driveshaft if its the units I think it is.
