Cam choice!

Call Racer Brown - he will SELL you want you [NEED].


for CR 9.5-10.5 Vizard says LSA 107 and intake duration 225 degrees for a max grocery getter every day driving power.

225, 236, 244, 255, 266 intake duration take you from mild to wild (moves power band from low to high)

Lower CR drops the LSA a bit more. Valve angle and a few other second order effects could raise that number a bit.

The only engine that comes out to 110 is a 318 with 2.02 valves.

would love to do a serious controlled experiment with a dyno and various camshaft variables changed carefully!
I say do it haphazardly so everyone can see the difference between a wiser choice and a off the shelf choice.

I went back and looked at the cam I put in the stock 318 Coronet. Good grief it is a 112 LSA and with those heads it should be 106-107 and with the low compression it should have been 105-106. No wonder I have always been totally dissatisfied with it beyond a cruiser. The Duster and Toth heads on the 318 should have been more like 110! Now I want to get new cams for those 2 cars! The 225 /6 I used Vizard and a simulator to choose the cam and it pulls stumps. Need to make the right choice on the 360 for the Valiant now.
Then follow is excellent advice on a pressure wave cancellation box.
