supercharger or nitrous on a oil burning motor?

if you plan to blow it sky-high, just slap a 150 shot on it, and go for broke...

but if you're going to assemble a new engine, honestly, its a waste of time, money, and weight to install a forged crank into a stock block...the crank would handle more than the block could...

a good cast steel crank from Scat, or Eagle would serve you well, and be alot less expensive (about $200 for a new crank), same goes for the rods, also about $200 a set for Scat forged I-beams...you can have fun with the pistons though, get a set of Probes, or something of that ilk, and you'll be set...until the block gives way

the part prices I'm quoting are from

www.cnc-motorsports.com

they have some great prices, and good availability. I squared away a Scat 331 crank, Scat 4340 I-beam cap screw rods, and probe dished pistons with total seal conventional rings from them for $900, the only thing I had to get to finish up the internals was the bearings. the other parts, like the oil pump, oil pump driveshaft, gaskets, and such will be purchased at a later date, but for what I paid, I think I got a good deal
