[Tigers] 331 camshaft

[Brent Edinger]

Roger are you running stock rocker ratio of 1.5:1? I have a set of 1.6:1

rockers and am trying to understand how the bigger ratio and more cubic inches

will effect the advertised camshaft numbers and performance.


Comp cams recommends 31-246-3   230/236 dur and .52 lift   110 LSA


Crower 15922   220/228 dur  and  .491/.512 lift   108 LSA


Still waiting on Lunati and Bullet to respond


 Brent

I'm also doing a 331 stroker motor, Scat crank and rods, and Wisco pistons. I have Promaxx heads with springs for a flat tappet cam, Edelbrock Performer Plus, 224int / 230exh @.050 essentially same numbers as a B303, 5.0 hipo cam but less lift for flat tappet cam. Quite manageable street cam. Flat torque curve to 5500 rpm.
? I use Shell Rotatella 30w oil which has the additives taken out of catalytic converter engine oil.
