new to this, 89 5.0 stock lower end 96 explorer heads and intake 373 gears 70mm throttle body h pipe no cats 73mm mass air, what is a good cam.
Thank you.
Jeff.
Stock valve springs can barely handle the stock cam, especially with some miles on them. I would say valve springs are a must. I have seen way too many engines gernaded due to people putting in cams with stock springs, bent valves at a minimum.
Yeah, a big cam might sound great, and might give you a little more PEAK horsepower but at the same time it will slaughter the rest of the powerband. Actually, it might even hurt your peak horsepower. Something mild. E-cam or a custom or comp cam with about a 214-218 intake and/or a 218-224 exaust will do you well.
