HARDLY what I would call "old news".
They are TRUE performance cams and not a lot of fun to drive around with.
But if you can take the rough idle and want a big block to breathe, these WILL get the job done quite nicely.
My stock spec L88 made 480rwhp with no tuning on the dyno. I just drove it there and they hooked it up. I honestly believe that I could have bettered that number with a bit of tweaking. Anyway, I think that even 40 year old technology proved itself to be pretty potent, even if "yesterday's news". The dyno operators were certainly very impressed. Only a few unjuiced/unblown engines have done better on this forum.
"Today's News", the new Crane solid roller is in, rocker geometry is now being adjusted. Hopefully engine/trans will be back in the car the next week.
Thanks to all for the info, I really like my Crane powermax cam, but just like the L-88 its pretty weak down low then watch out! I do love the sound it makes and when you stand behind the car the exhaust hits you pretty hard. I am off to the dyno shop tommorrow to see what the beast really does. I will post the results.....
That's what makes them old news, the modest lift for the duration. I had an LT1 cam in my street rod, and it needed 1.6 rockers. Then it was really fun, especially above 3000rpm. I imagine a similar rocker upgrade would help the big block cams. Joe
