I'm Awesome
This one?Factory cams are almost always not great. They almost always leave lots of performance on the table. Your budget option would be to just send the factory roller cam currently in the engine off to Delta Camshaft in Tacoma, WA. They can regrind your factory cam to whatever spec you want. Just call them and tell them what you have, what you intend to use the vehicle for, and they will grind the cam to suit your expected use. They reground the factory roller cam in my 97 L29 454 and it was $140 plus what I paid to ship it to them. It took them about 2 weeks to turn it around and have it back to me. Your other option is to just get an aftermarket cam. Summit cams are pretty great budget cams. I believe @L31MaxExpress had a pretty good breakdown of several different cams, including a Summit one that were great truck/towing cams for the L31.
L31 towing cam upgrade
I'm going to be installing a new L31 block in my 98 silverado to replace my tired stock engine. My truck does lots of towing and hauling. Is there a better cam for towing over the stock cam? I know the vortec heads are somewhat limited to the lift you can add without modification, and I don't...
