340 power up

[dukeboy_318]

I'm looking at building up a 340 to make into a street/strip motor, what would you guys recommend.  I haven't bought it yet, but i'm buying just the block, heads, crank from a 360 and a balancer, any suggestions.  I want as much power as possible on pump gas without blowing it up.

I say get a 4" stroker crank and sell the old one, even more ci=more hp.  If you do it right I beilieve you can make about 500hp on pump gas.  Also, buy the book "how to build big-inch Mopar small blocks", it's definately a book worth buying and it has a couple different combinations you could build with what you have.

I agree with this. 

There are people willing to pay some decent money for 340 blocks these days.  If you can get it cheap, then scoop it up and resell it.

You'd probably end up bucks-ahead by finding a 360 Magnum (5.9L) out of a wrecked 90's Dodge Ram pickup truck and putting a cheapo 4" stroker cast crank setup into it.  By mostly just re-using the stock Magnum parts you're already hitting the ground with about 410 inches, a roller cam, and some good cylinder heads.
