Geoff;
I'm also in the process of rebuilding my 235.
Mine is costing $1338.76 for all parts including new cam and lifters, boring .060", turning crank and flywheel surfacing, hot tank cleaning, new intake valves, hardened exhaust valve seats, balancing. That's with me doing the assembly. In-line Stovebolts are expensive! The last SBC V-8 I did cost about half that!
