that first crank journal is too far gone to try it in the car. that engine is ready for a full rebuild, as even if you don't intend, those pistons will drop out the bottom as soon as the crank is out of the way, and the only way to put them back in is through the top, while the crank is in place, and journal protectors are on the conrod studs/bolts.
since you need to pull it apart, now would be ideal for a few longevity/durability upgrades, if you find another six to put in, great! do it. but build this one to where you won't have to worry about this kind of stuff again. double roller timing chain, modern hardened steel camshaft/lifters. putting in new pushrods that you know aren't bent, roller tipped rocker assembly, ford SB8 Valve springs, since the head is off, 3-way valve job, and new valves, but the biggest durability modification would be to turn the journals down to fit the Toyota 1JZ-GTE H-beam conrods I mentioned earlier. all of these things can be done in a way to maintain the majority of the factory performance profile, however will greatly increase the engine's durability, especially since you have a seven-main crank.
there will always be mild to medium performance changes when altering the things I mentioned, however if you aren't going for high-end performance, all you will be doing is increasing the areas of the engine it already performs its best, and reducing its flaws, like hesitation if you apply the gas too quickly.
edit: just checked this, not sure if you did or not. seems pretty consistent that they have complaints near the end of a racing season
