sbc 327

This is the first time ive had any real trouble with this engine after finally getting in on the road, made numerous long trips to work and when I drove it on the highway doing 70+ I ran into a problem. The car is a 65' el camino and im pretty sure it may of just ran hot and now it wont restart...

Hello im having trouble figuring this out, im rebuilding a 327 sbc and im looking for new pushrods on summit racing and i think found the right ones but it says the intake rod length is the stock 7.794 and the exhaust rods are 8.684 is that right for a sbc or are all rods 7.794...
