I called Jim at Racer Brown. Gave him the info on my engine and its intended use. about 4100lbs with driver. automatic, 3000 stall & dana 60 4:10. With the flat top pistons at zero deck, 84cc combustion chambers, bowl blended sidewinder heads, and 1.7 rockers hes grinding me a solid single pattern cam with 254 duration @50, .554" lift, and I think he said 106 LSA. and the advance will ground into the cam.


He did say my stall will work, but I should upgrade to a custom made 5000 stall by a company he recommended. He says it will actually slip less than my 3000.
