Question about Blowers on our trucks

[mikep]

The 8-71 Blower sitting on top of the 454 in my dads 69 camaro has got me to thinking . Can I fit a 6-71 blower under the cowl hood of my 68 on top of a small block. I'd have to change pistons to flattop forged but other than that my bottom end is rock solid and could easily handle the extra 200 or so ft lbs of torque. If not how well do those little blowers work? Are they worth the effort? Income tax time is coming up and the joy of home ownership and its subsequent outrageous interest burden means I'll get a nice tax refund and if I play my cards right I can squirrel a little away before my wife confiscates it all.
