I'm bored and the internet grabbed ahold of me. The guy I want to build a crate engine for my f100 has several different engine packages to offer. He has what he calls the "workhorse" which comes in 501-557 cubic inches and makes 450hp with 615tq. Peak torque comes in at 3,000rpm and peak horsepower at 4500rpm. He also offers the "Street Hustler" for slightly less money. It comes in either 429 or 460 cubic inches and makes 520hp and 550tq. Peak torque is still at 3,000rpm and peak horsepower is moved up to 5,000rpm. Both should put my torque curve right where I would want it for a street vehicle that will see occasional towing duty.
I did some looking and the 7.3 powerstroke in Clint's Super Duty was rated at 260hp with 525tq. It's still stock and seems to get the job done fairly well, especially considering how much heavier his pickup is than mine. In my head, the extra 70 horsepower of the Street Hustler makes the loss of 65 lb/ft of torque worth it. And it's cheaper. Both options would make for a really fun daily driver. I'm just curious which way you would go if you had a 2wd long box daily driver that saw occasional towing duty.
does longevity of the motor play a factor here? say.. would one last the lifetime of the frame, or body, and the other one have to have rebuilds and extra maintenance to keep it running the way you want?
I would tend to lean toward the less expensive version, so that I could have money left over to do other things with it.
on the other side, will you ever beat yourself up about having too much power, other than when it comes time to fill up the fuel tank?
Well. The workhorse has an aftermarket stroker crank with hypereutectic pistons. The street hustler uses a factory crank with forged pistons. I don't know that one would be less reliable than the other since rpms are staying below 6500.
I feel like I personally would rather have the one higher in torque at lower RPM if it was me. The higher horsepower will be nice but how often are you gonna shoot it off the line?
Both will be monster engines. Unless you are planning to spend a bunch of time at the strip, the cheaper engine will probably be more than enough. Also, will these be pump gas engines and able to run on 87 or will they need premium? If you want the ultimate beast go for the workhorse. If you want to be a little more practical, go for the cheaper one. Either one will probably last longer than you drive the truck.
Either one will not be cheap to run and you probably won't be putting 10K miles a year on the truck. Also, this cheap gas will probably not last for a long time. For towing, the usable torque is what you will be needing and not at 6500 rpm. You will want your power in the 2000-4000 range.
Yep. Both are pump gas friendly. I figure even a stock rebuilt 460 is going to get terrible mileage. My Chevy also gets terrible mileage and runs on premium. Like you said, it won't have many miles put on it. Even as a daily driver I only put about 2-3000 miles on my vehicles per year living so close to work.
Looking back at your original post, I might be inclined to go with the workhorse if you are more interested in a tow monster. That's if the price difference isn't huge. In other words, if you are talking a couple of hundred more, I'd get the monster. When you get to $500-$1000 more, then it becomes diminishing returns for the gain.
Personally I would just do a 460 with hypereutectics edelbrock or trick flow top end kit looking at 500 HP and tq with headers it would be able to do anything you want and is everything you need while being drivable and dependable but stuck between your two options go for the tq just my opinion
