Thanks to both of you. I really don't want to give up on the old girl. She started life as a fire pumper and was pretty well taken care of. I've done a lot to it to get it reliable and running well (short of power). I've looked at the 4v53 and 6v53 option, along with the 6bt. All would be nice to have, but again, high expense to convert. I'm thinking the dt466 would be too big.

Unfortunately, if I can't find a reasonable resolution, she may become more of a weekend cruiser than a real worker. which I hate to do.

Truck is very strong off the line, all the way through 3rd and even 4 low, but once you hit 4 hi, it just falls flat. I will look at the carb situation, however, it doesn't feel like too much cfm, it feels like too little to keep the rpms up.

I'll do some digging on it.

thanks
