Without that info, you could find about two dozen potential cams that could work for your pulling needs.
They’ll need to know the valve size, rocker ratio, compression data, carb info, and other specs to give you the best fit. If you want the right fit for your setup, contact the cam manufacturer to get the correct options for your vehicle. When drivers want to haul them with a vehicle, they need enough power, strength, and torque available to have a successful experience.Īn RV cam is sometimes called a “pulling cam.” Although it can work with recreational vehicles, this choice is a generalized type that works well in the lower RPM range for more pulling power. Sold the truck with 180K miles and never did anything other than routine maintenance.Fifth wheels, trailers, and other heavy loads all have one thing in common.
However, they were solid as a rock under hard acceleration. I had one and the shifts were positive but not harsh under normal driving. If you haven't considered a B&M shift kit (the cheap one) I recommend it. I don't remember any real change in MPG as long as I kept my foot out of it. I had 308 gears and that truck would have flown if it had wings. The idle was slightly noticeable in mine but I had no trouble with the stock converter or vacuum devices. It also liked to rev so it may not be exactly what you want. I do remember it wasn't a torque monster but it added power. Times change and gas isn't what it was then so I don't know how that cam would do today. It's an old grind and there are probably others available that can do better.
I don't remember exactly because he rebuilt that motor so many times I forget what it had and when, but I know he started with the 3863151 GM and headers. This was a long time ago and he may have had a street intake. Our engines were stock but his had a rougher idle than mine. I bought mine from the GM parts counter and installed it at 30K with no other modifications other than headers. Said it was the cam GM used in the 350Horse\327 Corvette so I thought I would try one. A friend of mine was a mechanic at a Chevy dealer years ago and put one in his 74 truck with 373's in the rear.
