So I'm looking to bulletproof the bottom end after pistons 7 and 8 took a dump. I know the stock rods weigh in at 657g. Now let's say I was to go with a Carrillo rod that weighs in at 571g and upgrade the valve springs. Piston wise I was looking at diamond flat tops that also raise compression a tad to 9.9. Or should I just go with Manley stuff? I understand the cost issue here but I want to do this once. Are the Carrillo's worth the extra weight savings and money vs going with let's say a Manley h tuff rod or even Manley pro series I beam?. Should I bump compression? I am open to other manufacturers but will not do the drop in stuff. I understand also less rotating mass has less stress on the block. Future upgrades will possibly be that Whipple 3.0 and I am staying stock displacement with a possible .5-.10 overbore.

Don’t just throw a lighter rod or two into the mix, the whole rotating assembly needs to be balanced together, this will throw it off wildly.

Of course machine shop will do the balancing

Always change ALL connecting rods at once, then balance, as Kru510 said.

I went with a custom WISECO piston on a Manley H-Tuff rod, only 47 grams heavier then stock assembly, with King coated bearings in a torque plate honed block. Studs every where

Take a look at this thread will tell you allot

Stock Fuel Rails, why they don’t keep up

I think I stumbled on to why stock fuel rails don’t keep up especially once on corn. I switched to corn back in September, a Flex Fuel tune. I installed a dual 285 fuel pump set up on dual FPCM’s but stuck with my already tuned for on 93 ID1050X injectors. Tuner said it could be done on the...

I've never seen a connecting rod for F1, endurance racing, or Pro Stock that was an H-beam. They are all I-beams.
They strike me as being a marketing gimmick that also catches and throws a lot more oil around than the I-beams.
