When purchased the original (RP) code 350 4 bbl engine for this the GS 350 had low oil pressure and wiped out the cam and cam bearings.
I STILL HAVE THE ORIGINAL BLOCK AND HEADS! They go with the car.
I bought a 73 long block from Titan engines and built it to spec to the RP engine, but with much needed oiling upgrades, Stage1 valve springs and a performance Lunati cam 215/225 duration, advertised duration of 265/273 lift .470/.496. I did drop the compression to 9 to 1. It runs very good quick for what it is.
