I'm doing that same thing. My 454 has flattops it's been previously balanced. I'm thinking first I'll weigh the pistons then shop for lighter pins to see if it'll be just that easy. Another option is to take material out of the pin right in the center at the edges. Steel is heavier so it doesn't take much.
@@stoneyswolf thank you sir 👍 so I just have to wait until I remove the old pistons and compare weight to the replacements? I'm trying to get it completed in a weekend so my landlord doesn't freak out 🤣
If the new replacement pistons are lighter is less of an issue? Some folks on forums said its not as critical the crank will he "overbalanced" in that scenario which you can live with
@@hotrodhustle5456 I hope I can avoid having to have my components balanced...I f***d up and let Scoggin-dickey sell me a f***g a new GM short block years ago... it's got like 20cc dished Pistons (likely meant to go in a pickup truck🛻) and it's in a Vette so I want to swap in some flat tops to get the compression ratio back up to about 9.5 to 10:1 ...at least the motor only cost me $650..a new GM bare 4 bolt block was like $700 on summit back then. I should have done the swap back then but I didn't have the balls to tackle it
I’m pretty sure that it doesn’t really matter whether they match the old pistons weight. What matters is that all the pistons weigh the same individually. From the factory these motors aren’t balanced like a machine shop would balance a motor. It’s to labor intense for them to do that kind of work.
let us know how it works! I've had good results. I've even had broken valves smash on cast pistons I've weight matched like this, and the cast iron head broke before the piston
@@hotrodhustle5456 Tried taking weight off it, but it is such a small piston (1.4T engine).So after 5 grams had to give up. There was nothing more to take off without damaging it. So ended up buying another one( older model apparently) that it looks exactly like the other 3 in the engine. It should be here in a few days. Again, thanks for the video

Are lighter pins readily available?? I'm replacing dished Pistons with flat tops in a new GM short block
@@mariocooldude9092 summit racing has them

Is that your weed scale ⚖️😂😂😂😂
Lol I don't need one of those anymore. Lighter pistons are not a problem in my experience. Also constancy is the key when it comes to the scale

this engine had been rebuilt previously and I just wanted to get the piston close to what the old pistons were.
Nice video, thanks!
thank you, thanks for commenting,
Did it work? Need to remove 20 grams of a piston to match the others and avoid buying the whole set. Thanks for the video
yes sir it did work I've got probably 1000 miles on that engine and 20 1/8th mile passes I beat on it constantly
@@hotrodhustle5456Oh well I'm doing it as well then. Thank you for the superfast reply👍

I'm sorry it didn't work for you that is a lot to take off a small piston
