Stroker LS3 Build
I need some help and this is in regards too compression.. Using many of the parts I already have below trying to save costs by reusing what I can from the current build. The pistons I got for a good deal and are unused.
AFR V2 230 heads (62cc)
Wiesco .070 pistons +5cc
This will put my compression way too high to use pump gas.. If I have a custom gasket made .90 that should put me around 12.15.1.. my question is on a N/A motor will this cause me any issues with quench, reliability etc? Or should I shave some meat off the pistons.. which I really dont want to do.
As for the current build plan here it is.. feel free to comment/make suggestions
6.2 block
4.00 crank, 6.125 rods, .070 pistons +5cc
AFR V2 230 cathedral heads
Victor Jr
Pro Systems 1000 CFM carb
Stock rocker with Trunion kit
LS7 lifters currently but am undecided... might upgrade to CTSV or Johnsons
Custom Cam Motion cam - 246/252 111.5+2.5
TKO 600 Trans
thanks!
I'm Bored...
🤔 sitting in Camron louisiana in the middle of NOWHERE (marsh land > Homes), got my phone and Pluto Tv 😉🙃. BTW no electricity 🤣. Have Camper and generator will travel. Movie ref: Have gun Will Travel. Looks like a Bomb exploded. 🤔 Hurricane will do that? 😔🤨
Months after the fact 😔

Answer is: Either or. Fly cutting or cutting on pistons for a lower Compression is do able if there's meat on what's being cut? But 👎 Having gaskets made is Easier 😉
No issues with what your thinking your just giving space to lower your compression if the pistons out to much Deck wise, with a milled head. Do as normal check P/V clearances keep moving....

Launch (my Buddy) is talking about using 2 gaskets. 🤫 We just talking about creating space.
🤔 Or open up the Head chamber to your desired compression ratio? < Updated? < Engine builder chime in 😏 I just don't touch'em much😉.

I really don't think stacking head gaskets is safer than running a thicker gasket all together.
No offence on the engine builder comment, just hoping to get some other ideas as well

If it were me: I'd open the combustion chamber from 62 cc to 🤔 66 cc, if I could 68 to 70cc and gasket the rest. Cheaper than buying pistons, don't ask how I know 🤐. 🤫 Don't go telling everyone, but I've got .030 over flat top pistons for a 408 and dome tops Paid for . Still need to sonic test 1 of the 2 blocks I got for the second set. Your wanting to lose compression, I want more of it. BTW 62cc heads 🤔 me to, ✌️ pairs of.

Any other comments on the build Ive spec so far?
Thanks guys!
The AFR 230 heads I literally just bought 2 months ago and are brand new and will make more power. Im Canadian so by the time they got to my door they were pretty much $5000 CAD. Hard to take a loss that substantial.. that's the main reason!
Im selling the LS3 heads to recoup some of the costs of the engine purchase
Happy to be back in the City 😉
If I can find the time this wk-end, which I can't.
🤔 Shop's closed on wkends, but I need some sonic testing done. Maybe set it up on Monday, Vet. deal this time around 😉. Can we say no to these 12.1 JE Flat tops 🤨 and yes to a bigger bore dome top.
Yes🤫

Cause there Stand by piston on general purpose 🤣
🤔 The guys who are doing my build may need a set of ......now we talking my language $850 Sold.
They do Alot of LS builds and others, GG's there also 😉 Tuskey.
🤔
know a guy who makes this piston 🤫👇
14.5+ depending on gasket and deck height with 62cc heads
https://www.texas-speed.com/p-7517-c...0mm-steel.aspx
👆~>
14.5 + also depending on....with a smaller ring package. 🤔 If neither block goes this route .030 over piston from the CO listed above using already purchased T/S rings ^👆
https://www.lsxceleration.com/mahle-...kit-930229670/
🤔 On which piston is better
it all depends on builder preference and or Dealer whole sale deals with Multiple purchases. I use the who has what I want to accomplish method.Again have the chambers opened by a professional shop to get the compression wanted... top of my head ask (BES-Robert I think, FED-Chris, Mast-Darin etc) 2 do the work + shipping. Vs losing money then going out then buying new pistons.😉
Call and price having the chambers opened up VS your idea 😉🤫😏
