Hi all,

I'm about to pull out the 36hp power plant to do a number of things... I've been running a Judson with a 010 distributor for a while now, and its great. But, as with all mods, after awhile you want more.

I was thinking that while its out, I could put in a new cam to squeeze out a few more ponies. But seriously, does the power increase from the new cam warrant the effort of splitting the case?

Thanks,
Robo.

I'm really happy with my 36hp and would recommend a cam swap

My engine:

Stock stroke, counterweighted crank with lightened flywheel, pinned pressure plate all balanced by DPR
Stage 2 cam from Matthew K. at www.aircooledresearch.com
Ported/polished single port heads by Matthew K., Okrasa intake/exhaust valves
Stock balanced pistons
Stock manifold with 30pict1 carb
019 distributor

I'm running 1-3/8" merged header with a single quiet pack, but will move to Vintage Speed Abarth system shortly

I'm also in the process of installing Speedwell 1.4 rockers.

Be carefull with adding 1,4 rockers to the # 2 cam. You may be accellerating the valves faster than the springs will handle. In fact I think you will be, especially along with the charger.
