422 dyno fail

Jim Ward said

I really wanted to stay with the iron cylinder head. I paid good money to have them ported so they would flow. I am open to any intake suggestion as well as carb suggestions. Cams are very hard to come by I felt lucky to be able to get this camshaft. Open to any and all technical suggestions.

Maybe they flow well for an iron head, but [email protected] on a 422ci engine isn't very impressive at all. Sorry to tell you this but staying with iron and putting a bunch of cash into them was a mistake.

The cam looks fine.

I'm not familiar with that intake. The only intakes I run are eddy perf RPM and victors.

I think it would respond to more carb.

Also, try an HVH super sucker 1" spacer. They usually add 10-15hp and tq on a dyno.


Last, a dyno is a break in tool and a test and tuning tool. Don't get wrapped up in the numbers. I've had my car on two chassis dynos and one was humbling and the other was flattering. Guess what, same combo on both, same ET at the strip.
