Reliability in my opinion on these motors is a step above the Gen I SBC/BBC, changes in general efficiency, block and sealing design are where that comes from. 30 years of engineering they ought to have improved something, no? They can still break down and have failures but I'd wager the interval between on stock motors is longer by a good bit.
That being said, I'm planning on an LS Swap for "Drive-ability" Good power, starts every time in almost any weather, no distributor to tinker with, no carb to adjust. Just drive.
Of course, that's just me
