Thanks people! Matt..I think you're right! Just MORE ADDED INSURANCE!..sure can't hurt! Cab...guesstimating to be around 610-620 horsepower..at the crank,of course! Any suggestions on what aftermarket caps to buy/use??? THANKS! Randy B.


I like and use to buy, when they where still avaliable, the Mopar brand Ductile iron main caps. Buy them if you can find a set If not my next choice would be steel main caps. They're are a lot of other racers and engine guys on this site that I respect that have used aluminum main caps with no problems I'm not one of them, yet, so I can't and won't recommend parts that I haven't used
