Are the frame mounts the same as the Delta 88? The only Cutlass's that came with an Olds v8 was the late 70's with 260 and the 88 Cutlass with a 307 in Canada. Yes, the Hurst/Olds and 442 could be bought and were basically US cars, 307 HO of course. The 350 Olds is a great motor. The late 73-76 need flat top pistons and mild porting to hit that horsepower level. The 77-up have the crack prone 3A heads with terrible exhaust port. If the bore and pistons are good 330 or early 350 heads can be used. I picked up a 121,000 mile motor 30-50 psi hot oil pressure and great looking cylinders, $50.
