Good Cam Choice?

siuauto said

I am building a stroker 340 with a set of trick flow heads. It's a Molner 3.79 stroke with their H beam rods and Wisco forged pistons. The compression ratio is going to be 10.6:1. OTB Trick Flow Heads with Hughes 1.6 rocker arm. I have an Edelbrock air gap and Victor Jr for intakes (Any input there, too?), and a Holley super stealth sniper. Its going into a duster with a 4 speed and 3.91 gear with a 29" tall tire. Headers are TTI 1 3/4" primary
The car is not a race car but a hot street car that will go down the track a couple of times a year.
The cam in question is a Comp Cams solid roller with .288 duration (.243 @ .050) and .550 lift. Its on a 110 lobe separation.

Any thoughts on this cam? Too small? Too Big? etc...

Thanks,

I’d use the RPM on the street with that small cam.

In self would run a cam 10*@.050 larger at a min with a single plane.

The cam I don’t like and would look for a tighter LSA, 108 @ a min, 106 would work best IMO for not only more low speed torque but more power across the board.

The lift is lacking but not the end of the world. I myself like to take advantage of the cylinder heads port flow capabilities and lift the valve as much as possible. Cresting maximum flow with valve lift is needed on the street or track but better for max potential at the track IMO. Not a huge deal in getting max lift with the valve to head flow but it’s just grabbing all it’s worth.

The single plane will out HP the dual plane. The lack of low end torque is a killer on the street. On the track, your obviously ignoring it with the stall converter and launch RPM.
