Intake don't got a clue hear it has to be either a modified tunnel ram or a dual intake want to use edelbrock olds big block heads i hear you can get them modified to fit on the small block pistons and camshaft and lifters and connecting rods I'll let the engine builders get that as long as it's forged and name brand quality bottom end a full girdle msd distributor and would like and electric water pump these are the parts im gonna buy before i send the engine off need some input im all ears money wise im not worried about a budget so i want to do it right the first time so if it's any oldsmobile diesel guys out there im all ears tha

Hampton and Dyers offer the modified Olds roots intakes. Mark Remmel is doing a run of 4340 4" stroke cranks next year but in the gas 2.5" main size, $1500 US. You could run spacers, good luck.
