Well i just built a 300+hp SBC 350 for 900 bucks, But thats here in alabama.
Well anyway I bought a crank kit for 550$ which came with: Cast crank, Rings, Cam berrings, main/rod berrings, and hypertec flat top pistions, All seals and gaskets.
The cam is a 396 375hp blueprint with a 212/222 .50 duration with a 467/480 lift and 112 deg. lobe sep which was 100 bucks with lifters.
The rest of the money was in the block and head work which was just setting and freshing up the heads. If your not running NOS or turbos u dont need alot of money in it. If you have the money though for heads go with vortec which req a new intake to match the heads.
All in all u can build a decent SBC 350 for 1500 counting all the odds and ends.
Good luck in anything you do with it.
