A mild blow through turbo set up (keep the boost under 8 psi) can add ~40% power increase. Careful tuning and use of a MSD 6BTM or equivelent to pull timing out under boost will allow you to run stock internals. The key here is not to let the engine knock. A water methanol injection kit can also help.

Now if you really wanted to kick some 350 butt there is a way to do so. A stock internals 4200 with a turbo can make 500 RWHP. Not a quick fix but it'll put a smile on your face.. and send the 350 crowd a runnin'

Here is a link to a '52 chevy getting the swap done.. adding4200 power

I have a 51 GMC that started out with a built 292 - made about 200HP and drank gas like a sailor on leave at a bar.. it took a quick exit after 1 year..

Can't solved today's problems using the same technology/thinking that created them
