"Nightfire, post: 8794784, member: 38176"]Looking to replace the motor with another or rebuilding?
Hmmmm so many options. I'm planning on bolting on a trick flow top end kit but don't want to put it on a 200k+ bottom end. having someone else do the build would just be easier, but I'll wait if you're willing to spill the beans.

Sneaky, do share....

Me thinks Sneaky is incognito... LOL
Don't forget to have the rotating assembly balanced at the machine shop. I paid $200 for mine but should vary place to place.
Not necessary as it's externally balanced. As long as you use a matched set of rods, and a matched set of pistons, it'll be fine as long as you aren't going huge RPM with it (<6500) or making super big power (>600). The guy who ported my blower also does engine building (he has the fastest manual transmission Coyote 5.0, i.e. knows what he's talking about), and says he regularly builds mild 2-valve engine builds. For a budget build, he uses the exact same parts I listed above minus the pistons (I think he goes with a cheap set of Mahle's instead). Said he never has it balanced at the machine shop, and has never had a problem.
Take it FWIW. YMMV.
Oh really? Hmmm. My builder is always preaching balancing.
I wonder if the machine shop made any alterations or if it was "balanced" on the first spin and I threw $200 down the drain haha
Those rods come with bolts..mine from Tousley/AutoNation had them bolted on..
I'm sure they did it, and it definitely is 'better' to have it balanced. The question is whether or not 'better' is needed. My understanding is that the factory tolerances are quite wide when it comes to balancing, and anything aftermarket is well within that range. I suspect the rods I bought from a 2012 Boss 302 are WAY closer to each other than the ones in a 15 year old 2-valve motor. I weighed the pistons/wrist pins I got from a Cobra, and the total range on those was less than .5 grams. So I'm pretty sure I'll be good.
I really need to start up a build thread....[/quote]
Yes, spend the money upfront and then you will thank yourself later. A balance not only helps with motor life but also makes more power. Plus, that way instead of guessing, you know.
Just my .02
