Any real difference between factory 340 and 360 connecting rods?
Wow thats a heck of a deal if they are good. My machine shop guy, who i been friends with for years quoted me a whole lot more than that to rework my stock 360 rods.
Quote was for all the typical stuff one would check and or replace on a used rod thats been cycled over 100k. Shot peen, magnaflux, check for straightness, add ARP bolts, and resize big end. Mine are set up for press fit wrist pins.
Then he explained, its a stock 360 rod. Just because they have been magnafluxed and it currently shows no defects it doesnt mean that one if these rods is not gonna develop one, because they are used rods with a lotta miles on them.
Then he said, for the money i'm gonna have to spend on stock rods, i could just buy new forged ones and be done with it. They make new rods, it would be different if the aftermarket didnt offer replacements, then you would have to rework these.
Now he did all that type of work on a set of 2.2 turbo ll forged rods for a wicked little 300 hp shelby engine i built years ago, but that was because of 2 things. 1 theres no aftermarket support for those engines in the way of better than stock forged rods, and 2 turbo ll forged rods are very hard to find, so he redid what i had.
I like what i see with those speedmaster rods, and will likely pull the trigger on a set. I only plan on 400hp out of a 360 so they should live a long comfortable life in there.
