Swap 340 for magnum 360

There is nothing too special about a bone stock 73-340. About 8.5:1 compression 1.88 intake/1.60 exhaust valves. Crank is not forged either and it's external balance.
Do people desire them?. Yes for whatever reason. I have one I just pulled out if my scamp that I am going to do a pretty good build on here in the next couple months.

If I were to start a build from scratch it would be 360 based & LA not magnum everytime. The LA valve train is way superior than the magnum that has the stud mount rockers. Roller Lifters are now a drop in deal for the LA so for me LA wins no contest.
