Re: How far can you mill a head before pushrods are too long?

Aftermarket pushrods are available in .050 increments for a reason. Many people make the incorrect assumption that they are starting with a perfectly machined factory engine when they start a modification of this type. The factory allows a certain amount of +/- tolerances for all the machined portio...

Re: Offy C manifold or a DP?

It really depends on what other mods you plan to do to the engine. If it is going to be stock, with just the intake manifold change, then 600 CFM could be a little big. If you plan on headers and a cam change and perhaps some other performance enhancing items, then a 600 CFM might put you right on t...

Ok, I was thinking out loud. I know a 300 has a 5/8" or so dowel that fits into (2) counterbored head bolt holes in the block, and the head bolt goes thru them to locate these heads. So there wouldn't be any extra holes left over to make you realize something might be missing.

Good quality plug wires like this should check on an ohm meter around 800 ohms, so get a multimeter and eliminate a dead wire as a culprit. Also, make sure a plug wire hasn't gotten a bare spot rubbed or worn into it from engine vibration against a valve cover or sharp corner somewhere.
