It worked great. I did manage to break a single rocker by wildly over revving it and can say it wont stand 9500 rpm well. This engine is in a Morris Van with a Toyota 5speed gearbox and a 3.70:1 rear end.</div><div class="yiv2877519445qtdSeparateBR" id="yiv2877519445yui_3_16_0_1_1470670716873_4939" dir="ltr"> I too am building a 0.060 over 1275 with a wild cam. Its a Kent cam. I can dig up the specs if you need but I must say I will NOT be able to use the 1.7:1 rockers due to spring bind. The valves open too wide and compress coils of the valve springs against themselves. I am using heavy springs. I am not sure what I will do about this. I hope a switch to a 1.5:1 ratio rocker will cure the trouble. I will be putting this engine in my sprite with a 4.55:1 differential and a Datsun 5 speed gearbox.</div><div class="yiv2877519445qtdSeparateBR" id="yiv2877519445yui_3_16_0_1_1470670716873_4940" dir="ltr"> These vagaries aside I am well pleased with the performance of the rockers. They are much quieter than stock and allow a lively throttle response in the mid range and upward, 2500-6500 with the stock cam in the Morris van. I got them through Mini Spares.</div><div class="yiv2877519445qtdSeparateBR" id="yiv2877519445yui_3_16_0_1_1470670716873_4941" dir="ltr"><br></div><div class="yiv2877519445qtdSeparateBR" id="yiv2877519445yui_3_16_0_1_1470670716873_4942" dir="ltr">Good Luck, careful assembly will make it work, if all else fails throw money at it…</div></div></div></blockquote><div><br></div>This is where I am now!
