I think a Cam with those duration numbers will kill off too much needed average torque even in light of your running 3.55 gears out back
‘69-‘77 GPs are “G” bodies. The “B” body GPs ended in 1968.

Hello and thanks for the input,
Steve25, ponyakr, steelcityfirebird,Will I already have and running a 041 clone cam in now from Ken Ace Brewer PPR with the Rhoades lifters and SD Peformance setup the heads with the 041 clone in mind (but I will need to go back and check to make sure they will handle lift or I may look into other options for the rockers thanks for the reminder), along with the stock 71 intake so neither of those are a issue in my opinion. I think with the low first gear 3.06 plus the converter aren’t perfect… but do work together and the butt load of torque help elevate many issues. ;-) The 1971 is a G body not the B model, mine has a chevy 12 bolt rear end and I have the 3.07 gears now and it’s fun to play with, so the 3.55 will be an upgrade for sure and should move that 4XXX lb car around quite nicely.
Lee I always appreciate your input I always enjoy your comments and I have read a lot about your cars over the years on here…it’s all about the little things for sure. The rod thing is interesting because everyone was going to the longer rod so now I know what to look out for thanks.
For exhaust I’m running the log manifolds and dual 2 ¼ out the back but, I have the Tri-y from Ron Watts and plan on running the 3” back to X or H pipe to 3” Dynomax 17959 I have or Dyno Ultraflow, Super Turbo to 2.5 tail pipes… I like to speak softly but carry a big stick
Cliff I’m the great state of confusion Calif. And this cam only has 70° overlap , the engine will be 0 decked but we have watered down E85 here…. I am not sure if I want to chance the death rattle but I hear ya! What’s your thoughts on the overlap?
Jim
