440 build for a tow rig/"muscle" truck?

I would be very careful with the compression for a tow engine. Make sure to talk to your cam grinder and get dynamic compression figured out for your combo. 440's can be detonation prone with the big bore.

Aluminum heads will help, and hopefully they have the spark plug better located. I wouldn't spend the money on a roller set up but it is your checkbook not mine.

Stealth heads have stock spark plug location unfortunately (but supposedly fits better with headers). I'm not terribly worried about detonation because I'm also operating at 5000-8000 feet above sea level but it's still a consideration. And I'm still on the fence about roller vs. flat tappet, haven't decided yet.

I did clean my block and start masking it this past weekend. Tried the Uncle Tony method of going over the outside with a torch after using gunk/goop whatever in a can engine cleaner and pressure washing it a few times, we'll see how the paint turns out. I decided to go with Dupli-Color "Universal Gold" for the color as the original Golden Lion Chrysler big block color isn't readily available. Hopefully start getting pics up soon.
