When I was building my 302 to put in my 66 I asked the same question. The engine was to be mildly modified. Cam, intake, carb, headers. People told me that cast would work just fine as long as I stayed away from Nitrous or heavy racing. And the price is a lot better! I bought 8 stock cast pistons for the price of around 2 forged.

I agree with Pat. Hypereutectic pistons are a good comprimise between regular cast pistons and forged pistons. Hypereutectic alloys are tougher and more wear resistant than regular cast pistons due to their high silicon content. Keith Black has an excellent selection of hypereutectic pistons, as do others.
I know the original topic here is pistons, but I don't agree with the Nitrous concerns. If you get a mild (150 horsepower or less) nitrous kit, you will probably be fine with cast pistons. The main key is to make sure you have sufficient fuel supply and a little less than normal ignition timing. Nitrous actually acts as a shock absorber in the cylinder, and when used properly, will put much LESS wear on an engine than other "power adders" such as a big cam, which produces power at higher rpms. Nitrous produces additional power throughout the rpm range. I ran a 150 horsepower kit on my '68 Coupe for two years back in the early 1980s with no problems, and the motor is still running strong today (I now have a blower with those same cast pistons). I just wish I had not sold the nitrous, because I'd be putting it on my convertible right now!
It’s about 100 degrees here in sunny North Texas. Feels even hotter. We’ve got too much to do on my daughter’s car, so it’s time to get creative. I would have gotten a single larger unit, but my in-laws had these two 5,000btu units new in the box, so I’m giving them a test drive.

Im in the planning stage and need a few questions answered.
The wiring harness is out and when I reinstall it I want to add any additional wires/circuits that I will need before I stick the engine back in.
1. How many amps does the system draw? Will my 65 amp alternator do the job. Im not...
Well, not really dangerously hot, just hotter than I think it should be. For some history, 8 years ago it was running about the same temp as it is noe. I took the radiator in to a local radiator shop, and he cleaned out, but did not rod it out. After that it ran as cool as I feel it should...
One of my buddies painted his own car during his off Covid-19 off time and it does not look to bad.
He actually had body work experience as a youngster. He told me give it a try doing the primer and he would help.
If you have done any paint work on your mustang share how it went.
I figure at...
I have been trying to find a good video on how to remove the chrome trip. Lots show how to put it on, only one I saw taking it off and the video was really bad.
