So you want 2 go Big block...Read this first!

Just out of curriosity why would a 440 out of a motor home be a far cry from a 340?I think the late modle 340's where not as durable.Think about the fact that a motor home is built to go long distances...and hall alot of weight.I just disagree.

corect me if I am wrong I don't know the guts of engines verywell. a 440 motor home motor has a cast crank, and it is better to have a forged ( or is it the other way around) 340's have a better crank and a better platform to start with. 440 motor home is a smogger, where a 340 is a HP motor. 340 are high winding, where a 440 motor home one isn't.

I am pulling at strings on this one, but that is what I have heard, and think.

if you guys are comparing a 340 to a 440 which would you buy... a complete 440 for $500, or a complete 340 for $500? both may or may not run.
