340 Build- rocker questions

Looking for some incite and suggestions on going with 1.5 or 1.6 rockers to give a little extra lift to my current cam since I’ll be updating to speedmaster heads, 2.02/1.6 65cc port/polish, machine for larger pushrod/clearances to accommodate 1.6’s. Looking at using Hughes Engines rockers.

Planning to use .040 Felpro 1008 head gaskets

Cam- Crane 150062
3,000-6,000
228int/228exh @ .050
.480int/.480exh lift factory ratio
112 LSA
Speed pro forged pistons, .030 over
Slightly above deck
Eddy air gap
3.55 suregrip
4spd
Hedman LT headers


I would look around on line and find some cam math and then pick a different cam.

One of the best books for math of that sort is “The Horsepower Chain” by Don Terrell.

Its 80 bucks and AFAIK you can only get it through speedtalk.com unless you can find a used copy.

Im just not into that cam.
