416 stroker cam
i have a pro street 1986 Silverado that will be getting a 416 stroker .
motor will consist of
lq9 block bored .60 over
dss racing flat top pistons ceramic coated
6.125 rods
4.0 stroke
prc 247 heads
trans is a built 4l80e with 4000 triple disc
gears are 3.73s
weight should be around 3900
the cam is my issue ,should i run my g5x4 or what would you recommend?
i want to spray a small shot maybe a 125.
What intake manifold will you be running?
MS3 >>> 237/242 choice of LSA (111/112/113)
X4 >>> 240/244 111LSA (Like a MS4 on XE-R or should I say MS4 is like a G5X4 but with LSK lobe on intake)
Theses specs were found with a quick google search possted on Ls1tech by a very respected member.
Two cams I've toyed with in a 416 have been a 250/254 112+4 and a 252/260 114+3... same overlap but the 252/260 cam would peak much later, but would be optimized in a 416 with a FAST with an IVC of 54 degrees. The 250 is around 50 degrees, which would work better with a single plane type intake.
