Engine rebuild - advice wanted

[blykins]

Shouldn't be a problem.

The engine was built in 2000 and has probably seen 8,000 track miles since then, so we were thinking we'd rebuild this winter anyway. Guess it will be sooner than that.

Don't know what kind of rpms you'll turn with the engine or what rpm you usually shift at, nor what kind of maintenance you do on the engine or how hard you'll beat on it, but I will say after 8,000 track miles,you got your moneys worth out of it..........
and without knowing what all is damaged,it could be as little as the crankshaft or the whole bottom end........

I'm not trying to start a debate,nor am I looking for one,just stating what's in my 2 cars....

First car is a dedicated road race 65 Mustang,331 cu in.,alum. heads,13.5 to 1 compression, shift at 6500rpms, 7000 chip in the MSD box which I hit on almost every track..just shy of 500hp..I've run oil temps of up to 270 depending on the track and outside air temp......While I "use" the engine for it's intended purpose, I have at times abused it,but not on a regular basis....
With all that said and done, my rotating assy. is/was an Eagle 4340 forged unit...4340 forged crank,chevy journals,4340 forged H-beam 5.4 rods...solid roller camshaft,forged Diamond dome pistons....it ran 7 long hard seasons with only regular oil changes,probably as many miles as you'll put on you'lls car......
It did break, 100% my fault when I screwed up on re-assembly after 7 years.....all it required at the time was a light hone in the cylinders and new rings/bearings, that's it......I replaced the rotating assy. with another, the exact same one I had in there before.......
I saved the crank and 6 rods and they were re-used in another 331, street engine making about 425 hp....this is a street car engine (car #2,65 Fastback) that doesn't go past 6000 rpms.........so far,so good......
