Help choose the correct Pistons/Rods (Bore 3.898) stock 346 I'm doing H/C swap on my ss
and planing for shot of nitrous, so decided to go a head and change those stock pistons and connecting rods and keeping the stock crankshaft
I have PRC 5.3L stg 2.5 milled to 59cc to maintain the CR ~ 11:36
I don't want to loss this compression when changing pistons/rods and keep the current PTVC
Actually I don't want to spend alot on those , my badget is $1,3000
Can anyone please advise me what piston cc/ connecting rods length and brands that will not hurt my CR neither my PTVC

not sure what piston you should get but i have not really seen any co. that makes 3.898 forged pistons. i think 3.905 is what most companies make so you would need to get the block machined on a lil if you went with a 3.905 piston. also callies forged rods are around 550 +/-. but you can also get some stock length scat forged rods for 300, but would limit your piston selection. keep in mind you can also just buy a set of arp 2000 series rod bolts for 100 dollar and have all your stock rods resized for 40 buck. which would hold some decent hp for 140 dollars total? all depends on how much you willing to spend.

scat i-beam rods 6.1'' $320 after tax
mahle 3.898 piston pak $650 after tax
keep ur stock crank and ull have a motor that can handle big power for a little less than a grand. this is the setup up i have in my stock bore ls1 and im spraying a 250 shot on top of it. eagle stuff is heavy i like to stay away from it and dont put $140 into a stock rod when u can spend a little more and get forged i-beams

Nothin wrong with eagle, people have there own preferences. i have sold there stuff for over 10 years, and stands strong.. And yes a I beam in Eagle would be lighter, but i said H beam, there best rod.. Have buddys that have 1200 horsepower with that rod, i stay away from scat for my own reasons with balancing. but none the less everyone has there own reasons.
I clearly remember my Eagle crank being very porous and was a nightmare to balance. - bad pour... that was a bunch of years ago though.

Name ONE company that has not had any issue atleast once in they're products.. There is no such thing as perfection, just dealing with all the manufacturer's for years, i have had less problems with Eagle then any, if something is wrong they will fix it in a heartbeat..

As I said, things may have changed and thats good for you. And perhaps that was my point exactly, based on that prior post. No company is perfect, thanks for that insightful comment.
Im not quite sure if your just being a dick about this, but sure, Ill play your game.
you tell me something bad about Callies. - 1

Ok, first off, this is not a 'Name that company' bullcrap discussion, I was merely stating Eagle has had several years of bad porous metal, and Let me tell you, my service with Eagle, how they ignored the images provided by the race team that balanced it was awful.

Re Summit has both pin sizes. Just enter "Scat LS1 Rods" in the search and they come right up.The part number is the same except for the last 3 numbers "945/927"
