I'm restoring a 94 GT and plan on building a Windsor based 427 with an aftermarket block upon completing the resto. But the engine will take some months to a year even to do it the right way the first time and I have a factory 5.0 (hypereutectic pistons) that I am using to test a side project before fitting it to another engine in another car. My current plan is to replace the rod and crank bearings, lap the valves, replace the pistons with forged units from summit (and new rings with wider gap), and copper head gaskets with ARP studs. The cylinder walls were good 3 months ago (maybe 4 hours run time since then) so I plan on getting by with rehoning. Everything else stock with Megasquirt MS3X engine management (leftover from the 342 stroker I had in the car prior to teardown) and appropriate injectors.
The car is not and will not be a daily driver, I don't rely on it for transportation to and from work, I will not be heartbroken if I push too far and bend a rod, split the block, insert favorite catastrophic failure here. My question is at what boost level does failure become likely? Not looking for 100% safe levels as that has been covered to exhaustion. Just max levels that I will "probably" be okay at for 6 months to a year with an intercooled turbo setup. Stock bottom end, forged pistons, gapped rings, studs & copper head gaskets, and probably a high volume oil pump and a pyro. Thanks for any input.
