Another Camshaft/Valve Train newbie question
Posted: October 8th, 2015, 4:01 pm
Alright here goes. Ive been searching this forum for a few months now trying to get information on my stroker. I'm in the middle of it right now. The block and head have been cleaned, inspected and the rotating assembly has been installed.
I chose the Clegg Engine Stage III Kit:
Icon 4032 Forged Dish Pistons -21cc #IC944
Scat Enterprises 9000 Series Performance Cast Steel Crankshaft 3.895” Stroke #9-4.2L-3895
Connecting Rods 4.0L 242ci 6.125”
My question is what is a good aftermarket cam shaft for this specific setup. The ones that ive seen people use are the Comp 68-231-4 or the Crane #753901, i know there are a few others. I'm trying to keep this a middle of the road build for performance and cost, so i was trying to maintain the stock valves, and rocker arms. I want to maintain good low end torque because in the next year and a half it will be a permanent off road vehicle. Id like to make sure that my vacuum and idle specs stay within the suitable range without doing manual brakes, boosters, etc.
My head just gets scrambled trying to figure out lift height, spring rates, and rocker ratios. I honestly would love for someone to just tell me the best option for me (obviously there are a lot of opinions on "best") and stay in the $500-700 range for my camshaft/valvetrain altogether. I've learned quite a bit and i know there is a lot more i could learn but at this point id like to get this thing back and running.
Will i regret keeping the stock rocker arms?? I just really cant justify spending $400 for rocker arms.
Any info, advice, or suggestions would be much appreciated. At this point my head is full of numbers and ideas. I would hate to order a camshaft and camshaft kit and realize its not what i need or wanted. Thanks guys!
