Today, I fired my 360 up for my first break in. Its a relatively mild build @ .060 over with 9.3 compression, and a Summit street/strip cam. It is in my '66 Barracuda and I am using the 273 stock manifolds (I know I know, headers come later). I ran it around 2200-2400 RPM for only 7 minutes and had to shut down due to an oil leak, and my electric fan not kicking on. During the break in, my manifolds started glowing red hot. I had expected it to do that, based on several threads I have read on here....but how long should it go like that? It got so hot it melted my spark plug boots (small fire) on my brand new MSD 8.5s, #5 and #7 where the manifold wraps around the plug boot. That sucked :banghead:. It fired immediately, and I never really felt the timing was off, but due to all the commotion with oil leaks, smoke, spark plug boots, and temperature getting too hot, I never got a chance to actually check the timing to see where it was. My question is, can the timing being off cause it to continue to burn red hot like that? How long should it go red? Temperature got to 220ish...any worries there?
Thanks
