GlennLever:
I currently, in case you do not know, have a Pontiac engine in my dragster.

It has reached the limits of a stock block. An after market block (Pontiac) is 5 grand.

Thinking out of the box, if I were to go to a Hemi what should I know and what should I look at?

I would want to run 7.5 with it with the possibility of going to 7.0

Paul New:
Hate to say it but you will spend more than 5 grand to convert to a hemi you may as well buy the block!

For 7.0 racing I wouldn't start with anything less than a Donovan blocked 392  with some decent heads

For 7.50 racing you could run a cast iron block with some worked over 354 heads

That's 5 grand just for the block (Pontiac)

Paul New:
Yes I realize that is just for the block, but you do have all the other components already purchased.

True, more than you know (another crank, cam and set of heads.

Sure would be nice to get into a more "standard" setup though.
