Have a 88 318 looking for mods to help with pulling camper. It has 88,000 original mile and needs a little more power. Bought a hurricane horsepower mod and was wondering if this will help. Or should i drop a 360 into her?

Putting a 360 in out of the same kind of truck wouldn't do much, it might give you 15 more horses or something but it won't even be noticeable with a camper on I would think. Unless you put in a 360 that has been built so it has some power. A 360 from a truck like yours would have some pretty good torque though, that's about all those 360's are good for stock.

Don't do the 360, way too much extra things you'd have to do. Put a low end truck camshaft in it. Try putting taller gears in it (like 3.91's) it won't improve your MPG, but it'll pull a whole lot better.

Both mods are fairly cheap, but the labor will cost you a bundle if you can't do it yourself (which you can).

If you do the cam & lifters (have to do lifters too), this would be a good time to replace your timing chain, too.

Use an extra trans cooler, no matter what you do. (if Automatic).

(one good old slant six in a 400K mile '86 D100 that'll still pull a camper or boat all day long up hills..! Yes it IS a six cylinder, and it'll do 65 on the highway with a trailer all day long... takes a little to get to 65, but I've got time...!)
