Can anyone give me a link or a web site for various piston makers ( trw , srp , keith black etc. ). For some reason I cant find any. graemlins/clonk.gif
Thanks , Mitch

Did you try google? Type in the company name and you should get hits.

What about Wiseco pistons? Are they making GM pistons? I know they make 'em for motorcycles.

Flatlander racing (http://flatlanderracing.com/index.html)

the Wiseco Pro-Tru piston kit is a great buy.dirttrackthunder.com has them.click on the sales section for a possible discount.

I agree, the Wiseco ProTrue pistons are nice. When comparing prices don't forget to include rings. The ProTrues come with plasma moly rings. www.dirttrackthunder.com (http://www.dirttrackthunder.com) is a good place to shop, free shipping, too.

Thanks guys , but I'm still having trouble finding a forged 4.280 piston , 4.25 stroke , 6.385 rod to get a streetable comp. around 10.1 w/ 110 cc heads.

SRP Part# 143593 falls under 9:1 domed but with 110cc head ends up being closer to 10:1. The seem to be good enough quality made by JE and not bad priced either

Try the Je Piston site, http://www.jepistons.com/pdf/2002-srp-chevy.pdf they list Sportsman pistons with your specs, part #143583 closed chamber dome 10.6 cr w 110cc chambers. Might be able to bring it down a bit with thicker head gaskets and chamber clean up.

Can I use those closed chamber pistons w/ semi open chambered heads?

Mitch,
That is the 5cc dome piston (143593) I emailed you about & it is actually rated at 10.4 in a 112cc head. ;)

They say it is designed to fit EDE 112cc heads & GM standard heads whatever that means??

If I use that piston can I knock my compression down a below 10.5 w/ a thicker head gasket or will this mess w/ my quench to much ? Now my pistons are .0022 in the hole , hard to say what it will be after rebuild.What is the max compression I should go with for a street used motor.

Just ran the numbers & the SRP catalog seems to be wrong.
With a 5cc dome, 112cc chamber, .040 gasket & zero deck, I get 9.52 not 10.4??
You would need a 105cc chamber for 10.06

I checked also on two different sites and came up w/ similar results , I didnt want to doubt theyre stats cause I'm just a rookie.Mike is the 9.5 compression gonna give me adequate power for the street or would you like to see more?
Unsure of cam yet but I assume it wont be over .600 lift for the street :confused:
Thanks , Mitch

Mike,
I just ran the #'s for the 14cc dome and it came up 10.4. I wonder if there are people out there running a different compression then they think.
Mitch

With a good set of heads 550HP should not be a problem at 9.5 in a 489.

I have made 670 @ 6200 with a fairly mild solid roller & AFR heads at 9.8 on an honest dyno ;)

You will not have 9.5 though unless you use a different head gasket or deck the block with a 110cc head.
The nominal deck height is 9.8 for a rat & the nominal piston height is going to be .020 down with these pistons.
4.250/2+6.385+1.270=9.780
