[70rs/ss]

I am building a Vortec 383. I bought the complete longblock for $150 (GM core charge for guys replacing a Vortec with crate), so you can get them for that as I have bought two for the same price. Inexpensive 383 cast set up and I hope to have less than $1500 in it, worked Vortecs(062, screw in studs, guide plates, port work, better spring for over 500 lift!), big roller cam mutha thumpr (roller block) and throw down 400+hp. It won't go in my truck, but I would say it is about as low buck as it can get (by the time you R&R the crank, rods, etc a cast 383 rotating assembly is near even and a lot more power/torq) and if you need more umpff, NO2 if needed??
