You know they mentioned the Scr on the 410 as 10.1/1, but they never mentioned what it was on the 367.That's not fair!

I ran 11.3 on mine, with a 292/508/108 cam. I spun that one to 7200, cuz it just kept pulling.
But I found that not a good cam for a DD, nor a streeter. With 3.55s,and a clutch, the power didn't start until 47 mph.And I was disappointed with the torque at lower Rs. I advanced it twice during the summer, but by fall it was long-gone.
I replaced it with a 270/280/110cam @ 10.9Scr. That was a winner with gobs of torque. I ran this one with a number of different gears and transmissions,and carbs, always on the AirGap.
But that cam died in her 4th year, when they took the ZDDP out of the oil, and didn't send me a memo.
Next I installed a 276/286/110 also at 10.9Scr. It ain't much different ,but it sux gas in comparison........Yeah it lost a bit of torque, and gained a bit on top. With my new low gear, the power starts around 34mph. Now that's useful.She's been in there since 2004, now.
The 270 was my favorite.
