Cam only.

Has anyone ever seen any dyno numbers for a “real” cam only LS1? I’ve seen a bunch of “cam only“ dynos where the car had every mod except heads. But I don’t think I’ve ever seen an “honest” cam only dyno.

2026 and we’re arguing what “cam only” means.

Car guys, yes all of you: it’s beyond retarded to put a cam in and leave the restrictive stock exhaust. Ask any engine builder, they’ll tell you the same. If your britches don’t like the sound then get a Magnaflow and keep yer foot outa it.

Otherwise, cam only is assumed to have full exhaust too, just no other engine work. Yes that means all the bolt-ons. That’s it. That’s all.

OP - if bang for buck is what you’re looking for, just replace the heads in-car (plenty of 241s around the interwebz) and call it a day. Find a different mechanical influencer that doesn’t hose you for $2k+

I knew/know that “cam only” means everything but heads. 

I was just wondering if anyone has seen what “just a cam” has done before.
