for those that have done 4.8 pistons in a 5.3. Is it worth it. How much power can you expect. It’s basickly a stock 5.3 with a Cam and valve springs.

Very well worth it. Even better option is ls1 pistons. Only extra cost is bore and hone as our flat top 4.8s are same price as ls1s.
For the power difference look at the gen4 4.8 vs gen4 5.3. same heads cam and intake both with flat tops. quite a bit of difference.

thank you. Will look into that.

Only in an iron block 5.3. Can't bore an aluminum one that much.

Its been done quite often on both style blocks and gen4 iron as well.

I was looking on you’re site. Saw those cheap flat tops to fit LS1. They are like $225? Are they worth it? Or will they self destruct after like 10 miles. LOL

Iv perosnally used them in 5 iron ls1 builds and we hav about 20 customers running them now. Some on boost and nitrous too or big cams.
They are silvolite.

Wow. Silvolite has been around just short of forever... must be doing something right....

Steppin up their game also. We hope to have their other line ICON forged pistons soon and ill be using those in the all bore or all stroke buildoff.
Maybe even have some not so custom pistons from them as well in a hard anodized face and a few other options.

parrisw

oh wow. Ok. I’ve used them before. What kind of power you can make with a iron 5.3. Currently I put down 320 to the tires. With a Cam, springs, ls6 intake. I’d like to see 400 to the tires.

did you ever do your piston swap? How did it turn out?

pdxmotorhead

Last set of Silvolites I used I believe went in a restored 8N ford tractor.. Plain old cast. I mean what do you need at 1200 rpm anyway..
When we got them they were already many YEARs old NOS..

parrisw

No I left it low compression and did this instead. 😬😱😱😱
