Never ran Brooks 88 Aluminum Rods, I know they are supposedly new, but have they been zyglowed/ex-rayed, checked for proper lengths, that's pretty much a requirement to run them {even if they are new}most people that will want them will ask, it's kind of a prerequisite, to run them with out any worries... I'm not trying to discourage you or beat the price on down, or have a agenda to push either way, I'm not in the market for any... But I had many Childs & Alberts & Venolia's rods &/or pistons, in either N/A, N20 & Blown combos/apps, I got mine free sponsored usually from the late great Joe Pisano the owner of both companies {also owned JP1}, my Jobber cost was/would have been, about $100-$150 new ea. or more depending on actual rod in question {back as far as 1997-2000-ish, I would think Brooks or Bill Millers were comparably priced} or so If My Memory Is Correct for each rod after any discounts... I know you say they are new, in the box... But, Are you sure ??, I have old ones in boxes too, that you couldn't tell they've ever been run, especially by just looking at them, other than a couple minor scuff marks here or there, they aren't dinged up or banged up either {I will use them some day in something}... Also a used aluminum rod were, basically take outs, throwaways, souvenirs, not worth risking in a high $$$ combo or a boosted engine, after X amount of runs, depending on use & abuse, fuel types etc., basically paper weights & a dime a dozen... Most people were/are still afraid to use them on the street... Even if they are new... I personally had used them in street engines for years, they do stretch, your not supposed to compression break, gear down an engine with aluminum rods, but I never had a rod failure... But also the value of a used aluminum rod is really subject to it's usage & new but vintage, even new still in a box, an old aluminum rod IMHFO is worth maybe $0.25 cents on the dollar at most of it's new purchase price, you see them being sold for pennies on the dollar... So maybe I would est. worth $200-$300 or so, maybe would be a good price for a complete set, maybe more, you will need to test the waters & see yourself I guess... I also see there's no bronze bushing in the small end, that may also be a negative to some people, looking for an aluminum rod, I know I always used them... Just for an educational purpose {not that you don't already know}, You have to set up an aluminum rod combo engine much different in clearances, deck heights etc., so it will no doubt scare a bunch of people off, from even considering trying/buying them, they do have a cycle life, no matter what some will say & about 1/10 that of steel "supposedly", aluminum goes thru heat & stretching/growth cycles, much more than it's steel counterpart does & it becomes brittle eventually... You need to have more room for expansion, of the aluminum in pin area, length & girth/growth also, so you or the buyer, will need more clearances, the crankshaft lightened ground, polished, chamfered, for the proper bob weights &/or balance/clearances, or it will vibrate like hell... For use of the much lighter aluminum rods & the rod bearings, are very specific for use with an aluminum rod, the bearing has with a chamfered hole for the "pinned" style bearing needed, made of different materials usually also, the pin is there to help, so they won't spin with rod growth or @ high RPMs... It will need to be someone who's wanting/willing to go the extra mile/or expense of custom pistons, pins, rings & bearings, machine work etc. & run an old/even if they're new set of Brooks 88 aluminum rods.... Sorry for the long winded, overly **** answer & Good luck with your sale, either way, I hope this helps some...
