I'm a big power guy (don't let the fact that i drive a 2.3 fool you), so I'd definitely take the chance on the forged motor. 420 crank hp isn't even close to the ceiling on that setup. Heads would be worth the 500 themselves

My credo
If you don't have time to do it right will you have time to do it over?
Before you use it, please strip it down and send the block to a machine shop to have it boiled out, buy a new oil pump and pickup, and clean everything like it had the virus. My son had a Crane cam lose a lobe shortly after he built it and ended up with scored cylinders, a junk crank and bearings. You shouldn't necessarily have to run diesel oil but a zddp additive is cheap insurance. The break in process with a new flat tappet cam is critical, after starting bring it up to 1500-2000 rpms and run it 20 minutes,varying the rpms constantly, then change the oil and filter- making sure to add more zddp. One of my former techs always plays with GM's, he built a SBC for his Camaro, did the break in but didn't change the oil. That meant the metal particles shed during break in were still in the oil. He sold the car shortly after and the new owner came back complaining that the cam had failed within 2 months. Do it right or do it over- and pay twice.
