Subject: Re: Thoughts on my 405. by pr0zac on 2009/5/11 15:28:32 i have had that cam in an 11:1 383 with vortec heads. it was a nice cam but i think that the duration and lobe separation will push your hp up the band where you don't want to be quote unquote. i had a 3000 stall and 4.57 gears so it found its way into the powerband quickly. but i would imagine a lower duration cam would work better. especially if you intend to use the 3.08's it would take it a while for the cam to come in. i use to have 2.73's in my trans am and a hot cam with a 2300 stall. it seemed to drag its ass to come into the cam also. i know it would have loved better gears. i have a 230/236 in my trans am now with a 4k stall and 3.23 gears and before i was still using my old 2300 stall and on the 2-3 shift it would fall out of the cam and cars that i would be pulling away from would make the ground back up and once i got back into the cam it would start pulling off again if i didn't fall too far back. the new stall allows me to keep the rpms up and stay in the cam. all setups drove around fine. all these guys talk about just driving the car and not being concerned with high rpm performance yada yada yada. well if you arent going to run the car whats the point of stroking boring heads cam stickers whatever. you might as well leave it stock cause its going to drive the same or worse if you are just going to putt around. not doing gears is going to seriously effect the overall performance of the car if you aren't using a larger stall with a larger duration cam |
