Q: I have a 1988 Mustang that will get a 1970 460 big block. So far, the engine has been bored .030 over, has TRW 10.5:1 forged pistons, ported and polished 1970 429 heads with 2.245/1.725 inch valves, and an Edelbrock Victor 460 intake port matched to the heads. The car has an 8.8-inch rear

I’m confused. I see all kinds of opinions about iridium and platinum spark plugs versus the normal copper plugs. Some say they’re good while others say not to use them because they’re only for late model cars that are concerned with emissions. I like the idea of spark plugs that could last longer. I have

Q: I have a 1970 El Camino that will be used as a daily driver performance car. I have a Chevy 350 small block that I want to assemble with the following parts: Summit Racing Engine Rebuild Kit (9.73:1 compression) Summit Racing Camshaft Kit (224° duration at 0.50″, 0.465″ lift) Stock heads with 1.94″/1.50″ inch
