hey i was outlining the parts necessary for a 8-71 blower motor and was wondering if it is a must to get a 4340 steel crank. after looking at the price of a steel nitrited lunati BB crank i realized why there are not many blown cars around. this does'nt scare me off it took three years to finance and build my first BB so i've got patience. thanks

Depends what you are doing. If you are just building a street driver and occasional racer a stock forged steel crank will work fine. If it is a all out comp engine, then aftermarket for sure. FYI, right now in my racecar I run a stock 427 crank in my blower motor, 7.65 @ 179 in a 2500 lb car. New engine I just bought a Callies crank and spent big $$ on it, but I know it is a much better part and my first engine will be a spare. Its the old saying, you pay for what you get. I built the first engine on a budget. Luckily it ran good and held together.
