Question I have a set of cnc ported LT1 heads 182cc intake runner flow 278@.600 I and 201@.600 E and I'm building a budget 383 and I'm wondering what cam to go with, I have a Comp 230/230 .560/.560 112 lsa, Comp lifters, LE ported LT1 intake, 58mm Holley tb, Rollmaster timing set, Canton oilpan, Coated Pacesetter LT's, 2800 stall built A4, 3.73's and I will be running a custom tuned pcm to start. I was wondering if the 847 cam would make more hp/tq in my combo, my goals are 425 whp/ 430 wtq and the ability to run mid 11's on motor. With my converter and gear should I stick with the cam I have or get something like the 847, all thoughts and opinions are welcome.

 

the gm847 is what i would recommend..as long as you dont mind spinning higher rpm's...they make great power, and the driveability isnt too bad either

 

Thanks!
