Truck has been parked for the season but i want to get a head start for next season. Im interested in changing out the stock cam in my 235 that only has 1200 miles on it. Currently the pull is nice from the 1500ish to 2000 ish rpm area but drops off after that like crazy. I have searched this site and other and have found lots of great info however i cant get consistent nor detailed info about the rpm ranges affected by different cams.
I was thinking about going with what Patric calls a 3/4 mild 254 cam. After talking to him the suggested going with the 3/4 264 cam that is more aggressive. Both of these cams already are more aggressive than the stock 261 cam that people use. My truck is for street use and currently has dual intake, headers, HEI and a 3 speed and overall is geared short. Compression is holding nice at an average of 143psi per cylinder. I will change the rear end ratio next spring to help it out and then possibly install a t-5 trans later.
Can anyone comment or provide more detail on the affected rpm ranges for the different cams? I dont care one bit about sound or having it idle a bit rough as long as its still drivable in the city. Patric never had any real number answers but swears i should go with the 3/4 264 one as it would pull hard thru the entire rpm range. Can anyone back that up?
