73 340 SB Rebuild, Need Help Selecting Parts

Plan B:
So I am think about possibly doing this:
1. Maybe buying the 408 short block listed at Jegs and Summit. $ + shipping $2500.00
2. Working my heads and using them: Free
3. What cam would be a nice addition to this mix? $250
4. Gaskets, seals stuff needed: $250.00
What would this motor run like? About ?? HP and TQ?

How would this work with my basically stock converter and rear gear. I do like the gear as it's almost perfect for autox in first gear. Nice wide range from 0 to about 55 mph @ 5500rpm.

What's the good and bad about this idea. I am somewhat limited in total funds and this is my toy car to wife limits as well. I am trying to get a freshened up motor done for around $3000 out the door. Is this possible?

I'mnot sure what your machinist shops costs are. They vary to much local, never mind around the country.
The idea of the create chort block is a nice one. Double check with the vendor to as what exactly it is and needs. What balance is it and what flex plate does it require, etc...
Go see a FABO vendor, Pace Performance, member Johnny Pace here is mpost helpful.

I'd look at a cam like Boingk has. OR a slight smaller depending apon the track straight away length. The big cubes eats up a little duration. Knowing your turning a lot requires more torque than HP. Check with the fellas here that race this circuit.

Keep working on your steering and suspension!
