Valve spring limitations vs Cam selection
Hi Guys,
I have a set of EQ CH318-B 1.88/1.62 heads that I plan to use on a fresh 5.9 Magnum short block with SpeedPro H655CP flat top pistons .030 overbore. CR will be around 9.4:1. The EQ heads have Comp 26975-16 single valve springs installed and factory rocker set-up. Since the heads have only about 10 hours on them, I would like to work with what I have. My question is what are my limitations and concerns on cam choices with these spring specs? The current coil bind clearance is good. I do not need to go over .525 lift or anything and more likely closer to .500 or under. My plan for the build is a hot street/cruise/corner burner 370HP/425TQ ish running 2400 stall and 3.55 gears. If you want to throw in a cam suggestion from your build experience, that would be a bonus but I will be asking Oregon, Bullet, Schneider, Racer Brown, etc.
Thank You.
Seat pressure is 120# and 325# at 1.160 installed height.
