Twin Turbo Roller?

forced 340 said
416 blow through(73' 340 block)... 900+ rwhp, 93 oct, 3:23 gear, drive anywhere....

and from another thread:

i broke one... but it was when i had the 340, 740gram trw pistons, and 10#s of boost making 640 rwhp. nasty break too... broke the cam, block, starter, oil filter relocater, and oil pump/pan! i knew...

just means you have to be very dedicated to do a successful turbo mod and be willing to make a few mistakes along the way.

sure they will work, but they take a lot more work to make them work.

i'm not sure of the cost comparisons
