I did some trading and ended up with a beautiful set of NIB Holley refurb 450 mechanical secondaries. These are not used carbs, generally Holley catches them on QC. They tend not to be mainstream FE carbs, but I have used carbs like them on 390s, a 454 med riser, and a stock-ish 428 PI with success. Even made 550 hp with the vac secondary version on a 462. In the end though, without a build planned for them, looking to flip They go for up to 500 a piece, looking for 500 for the pair plus the ride or BO. Thanks!
Thanks!!!!
