Default Cam selection

I don't know, but i've alway found that the lower lift cams produce more touque than the higher lift cams. I also install every cam at 102 if the car weighs more than 2300lbs. Case in point i built a 388" cheap motor with AFR 335's fully ported for a 3000 lb Camero ladder bar car. It has 14X33 tires with a 5.83 gear 1/8 mi car only, also a 5500 PTC converter with a PG. The heads were 48CC, and had a 3 3/4" toilet bowl on alcohol. 14.86 compression.
It had 1.27 60' time at 3 different tracks. i installed the cam at 102. it was an old on the shelf cam, that i didn't think would work with this heavy of a car. But at 72 yrs old i'm still learning. Below is the cam i installed using 1.5 rockers. I know it's hard to believe but there are 100's of witnessses and many saw it run 5.92 at Byhalia last yr.@111 MPH, with 1.27 60' times, carrieing the wheels for 100 ft plus.


Below is the cam used, i don't like it but real hard to argue with results.
