i rebuilt a 305 for my truck i had over 600 dollars in parts (rebuild kit, rods rockers vavles vavle guides, a new crank) ect..) i did all the machine work at school with teacher supervision, but if i had to pay for all that machine work i'd been at close to 1500 dollars, and you can get a gm 350 290hp turn key for 1900, all on what you want to do

Lots of good info I still have an old 283 packed in grease,2 steel cranks,a set of sj 327 rods , & a set of 520 casting(powerpack) heads.....for a lite weight A bone rod ,that I might build (someday) I like the little short stroke motors, but they do best in a light weight car, with a stick shift/low gears! A 350 cube crate, would be a nice option, & if you dont need that old L-82 cam, the base crate is a tad cheaper? Just fruit for thought best of fun,crazyL
