Just heard from the machine shop and I cannot reuse the factory rods. they are egg shaped. 2 thousands out at the sides. He told me could cause oil pressure problems at idle. So I have found the Scat replacement rods with floating pins for $185 through CNCMOTORSPORTS.com. Give me feedback on Scat.

I'd think they should be able to recondition the rods if they have the equipment for it. Anyway, I'm running the 5.7" Scat 4340 rods in mine with the floating pin. I spent close to $300 on mine, but they were also single rib caps with dowl alignment using capscrews rather than rod bolts, and I had to get them machined to fit on a Ford crank since they're Chevy rods. They're qa good deal though, less than $200 for the basic floating pin set that'll take more abuse than the stock block will. Hard to go wrong with them for the quality and price.

Thanks for the info. We talked about reconditioning the factory rods, but this is the 2nd rebuild for them and they were abused before, so I since I can get new cheaper than reconditioning the old, I think I will go with the new.

In this case...get some new ones.

Scat will be fine for your build.

Normally I would say have them resized.

scat is a good name, but make sure your pistons have grooves for wrist pin locks if your going with a floating rod.

another route should be a recon'd stock set from them preferably with ARP bolts. (any machine shop should have extra SBF rods laying around)

btw, here's some cheaper aftermarket rods - surely stronger than the wimpy stock ford pieces

and heres some a for a little more

chevy rods on a for crank?
im curious on what your stroke is with those 5.7" rods

Assuming he is talking about a Ford engine, it could change the stroke or piston height.

I used 5.7" Scat rods for a SBC app, with 1" c/h Mahle pistons also for Chevy(though a different application than for the rods)so the installed height of rod/piston is the same, and it's still the 3" stroke but with a 1.9 rod ratio. To make them fit the rods had to be cut on a lathe to narrow the big end slightly so there'd be the correct rod side clearance when installed. Also the crankpins had to be cut to 2.100" SBC conrod size and SBC rod bearings were used(which also had to be cut on a lathe). The main reason is I get more piston dwell and have a lighter piston, on account of the reduced compression height. Less piston velocity at high rpm and less side loading are just icing on the cake. It sounds like a lot, but the machining didn't take the shop too long to do and didn't cost much, and it all went together like it was factory without issue.

Nice job...

5.7 + 1.5 + 1 = 8.2...good work.
