Nice read. I think I shift about 4800 now with the small cam (no tach). Will probably shift about 5500-5600 rpms with the next cam, but the engine will decide.

And if you’re shifting at 5500 then the Hot Rod article shows there’s pretty much no advantage to a solid, at least in their article comparing only two cams in a single engine.

You're putting together a low-budget pile of crap with whatever you can scrounge around and get and be satisfied with it and that's what you want. 318 is looking for 2 and 1/2 seconds of performance...
He's put the money out for Doug's header's, he's put the money out for aluminum heads, he's put the money out for Mickey Thompson drag radials... do you see the direction that he's going and looking for???... He tries to get to the drag strip as much as he can afford each summer for his enjoyment and fun and progress reports. He has a goal...
In my opinion all these things he's looking to do lineup much more with a solid lifter Cam and adjustable rockers...
As the article link prh posted there's more horsepower to be had..

Did you read the article? Look at the dyno results? That was a 440 running 10.7:1 compression and being spun to over 6k. A 440, spinning more than 6k and over 550 hp. That’s not exactly a mild build is it?

And even still, where did the difference show up? Above 5500 rpm. Below that it was even or the hydraulic was ahead. So, with a 703 he’s gonna be shifting below 6k. Probably right at 5500-5600, like the cams power range suggests. So what is the solid going to do for him there? Nothing. Above that? Sure, advantage solid cam. But that’s not a match to the cam specs he’s planning.

And really, that article compares two cams in only one engine. I mean, props to the writers for actually trying to compare similar cams. But two cams? One engine? That’s hardly definitive. It’s a single build. It’s not bad data, but it’s not nearly enough to settle the debate or prove anything really.
