340 cam for 318

Baggs said
Currently 4.11. 727 transmission. No power brakes, only vacuum I think, will be for the distributor.
Here’s a screen capture of the one I was looking at.

Your best bet for your engine, just make sure you have enough room for the valve lift.
Howards Cams, Hydraulic Flat Tappet Camshaft, Chrysler SB 273-360/318, 208/214 @ .050, .479/.494, 110 LS - Competition Products

It’s only a few degrees larger than a OEM 360 cam. “Small”

i personally think that's a buncha lift for a low comp 318 with stock small valve heads and a restrictive intake

Lift has no bearing on any concerns but will certainly aid in power.
The OEM heads flow well to 500 lift. The head can handle it and the engine won’t go down on power.

(he's gonna run a street master and something like a 500cfm carb).

I hope not! Terrible intake, carb to small

junkyardhero said
the duration is good,

He can get away with another 8-10 degrees @050 easy without ill effect. Been there done this.

junkyardhero said
the 110 is good but the combo

Not really. If he had a 318 w/a 2.02, id says yes.
He can use a cam with a LSA around 108 / 107

junkyardhero said
isn't there to take advantage of all that lift.

Not true

As I said above, 216/218@050 can be done. It’s power is just a few hundred rpm off of idle, works with a stock converter, even more so with 4.10’s!

An OEM 4bbl or Performer intake works well here w/a 600 cfm carb.

IMO, any cam under 210@050 is a weeny cam with the gear ratio and intended driving conditions listed by the OP.

PRH and Fishmen gave nice cam recommendations.
