Building a budget 346-are the stock rods any good? I'm thinking about building a budget 346 to handle around 650-700 rwhp max. More or less it will be making slightly more than the 600 but be pounded on alot more than the stock bottom end. The only major expenditure will be getting new forged pistons. My questions is what can the stock rods realisticaly handle? I will get some ARP's and of course polish the beams-are they good for that? Also 700 rwhp will be the max ever-as the C5 fuel system will need a overhaul to handle more and i'm not prepared to do that. Thanks!

The main reason I was asking is because I may be able to get a set of forged pistons for cheap-but they have the bigger pin for stock rods. Who makes the 6.125 rods for $350? I have seens some rods on ebay by bulldog racing? there like $299 for set of H-beams? There probably some sort of off-shore rod but from what I understand should be fine for any rebuild ( once they re balanced and all measurements checked) under 800 rwhp?

Eagle 6.125s for $383
Eagle 6.125s for $377.
Scat makes pretty decent stuff and these are only $288.
All three already come with ARP bolts, and all three would be undoubtedly stronger than stockers.

That's why i'm wondering if the stock rod can handle the power-there are so many stock bottom ends making 600 rwhp. It seems the only week point there is the pistons as they will not handle any form of detonation.

I'd be interested in those pistons if you don't buy them. Comparing my Eagle I beam to the Stock rod they look similar. I'd have no worries pushing a stock rod with arp rod bolts to 1000 hp. I'm also a cheap bastard too. I got my diamond pistons used for $200 and then needed 6.125 rods with .927 wrist pins. I bought eagle SBC I beams for $270.

Just buy one already assembled with pistons/rods forged and save yourself the trouble. Do you really want to use stock rods and be adding this motor to your list if something was to let go? Cars a poor investment, and even poorer if you don't do it right the first time.
Good Luck,

I know TSP sell stock 346-347's for around $2500 which is a good deal. Problem for me is getting it up to Canada. I don't know of any shops around say the Michigan, NY area. The person who would be doing the buildup is Paul DeSilva formerly of J&P performance-He's Joe DeSilva's brother-those guys are famous for 5.0 mustangs. I know %.0 mustangs and LS1's are 2 different things but those stock 5.0 blocks can make 600 rwhp on stock components when prepped properly. The attention to detail that goes inot a motor Paul builds is second to none. Again Car will not go over 600 rwhp-I just want the security of forged pistons. I don't want to get too far into it as i really want to pick up a new Z06.

I'd go with the Scat I-beams.. you can get them pretty cheap and from what I was told it's a nice light piece. You only need a $1,000,000 set of rods if you're going to be pushing high RPMs. If you're going to stay around the stock redline, a set of stock rods or a set of forged I-beam rods will be an excellent choice. If you're going to be shifting at 7,000-7,500 RPMs, well that may be a different story.

The car will not revved any higher than the stock 6600 rpm redline? Does anyone make an aftermarket rod for a press fit pin-the larger .947 diameter not the full floating .927 diameter ones? I looked at Eagle's web site and they only had rods for full floating pistons.

You can never go wrong upgrading parts while your into the shortblock. But I would trust the stock rods to 500 rwhp but no more. Of course as stated above, ARP bolts and forged pistons are a must. Good luck.

Don't upgrade them and you will be kicking yourself later - if your already balancing the rotating assy and such there is no point saving $700 and skipping rods
