327 Build Cam Selection
Hey Guys
Getting the 327 done and need to pick a cam soon. The car is a 66 Nova 2 door hardtop. Small journal 327, .030" over, Muncie 4 speed, 12 Bolt 3.73:1 Eaton with around a 24.5" rear tire.
The car is a going to be a cruiser with the odd mash of the throttle..lol
No power brakes.
Using flat top Speed pro hypers, decked block, .040" quench, around 62 cc domes in 291 double humps. 2.0/1.6 valves. Guide plates, screw in studs. Running a holley 600, L79 490 winters intakes, 1.5" headers with duals and an H-pipe. Electronic ignition.
Static compression is between 9.85 and 10 depending on exactly where the heads come in at.
Looking at the following cams. My builder likes the old Comp 270H. I was thinking it might build a little too much dynamic compression with an IVC of 61
With the 10.0:1 compression the 270H comes in at 8.14 dynamic. Too high?
I like the XE274 with IVC of 63 bring the dynamic right to 8.0 if I hit right arout 10:1. Comp tech line which originally told me to go XE268 is now saying XE 274 or Comp 280..
Thoughts are appreciated.
Could it be a 10114182? If so, it is a Gen V 454, 4 bolt 1991 (or later). Hope that helps..
