I would go on another dyno before you pull heads.. Maybe the dude had fat fingers and keyed in a heavier weight for the car...
Why do you ask? It's negligible just like the calculator showed. When building a motor you never know exactly what you will get, especially when the block is decked. Hence the measurement just to make sure.
Well I did a compression test to compare both sides of the engine. Passanger 140 drivers side 135 so they are similar at least. Thinking about taking a valve cover off to measure the cam make sure it's a stock cam
Any1 with e85 and 1000cc injectors, how much MPG were you getting at cruise?
Okay I'm seeing 11.5 mpg with bosch 1000cc's and the e85 thats cruising in 6th gear.. so you all seem to be higher in that department as well, which I believe also points to lower compression correct? Higher compression = better mpg to my understanding?
Also the guy at the shop who assembled the engine is looking for the numbers he wrote down but they said they always check piston to deck dimensions and that they wouldn't let something go that was way out of wack. Oye

So when I pull this head off and I indeed have like 7 or maybe even lower compression.. whats my game plan? Do I have MMR replace with the correct parts and rebuild, do I slap on some crazy big supercharger instead? Do I just part the car out and say fuck it? LOL or do I just keep it as is.
Ah man
Do I have MMR replace with the correct parts and rebuild,
I think I'm going to pull the engine myself this time, do the teardown myself. . Then at least I can really clean up the engine bay and paint the engine block this time. Plus it'll save me a lot of money.
I wonder what the chances of me not having to do any work to the block is. I've got 5k miles on the new engine. Ugh all I see is $$$$$$ LOL
You'll at least have to have it balanced with new pistons.
**Hey serious question lol, what about nitrous? Used nitrous kit would cost me WAY less in time/money than tearing down/rebuild for now.. prob still crack into 700 rwhp on a 150 shot and wouldn't the lower compression mean I have more room to run it anyway?
Well I stuck a bore scope in there and I feel pretty confident I have the -18 instead of -11 cc pistons. Which we always figured was the case. But maybe between that, the 4.75 stroke and possibly thicker than stock head gasket I'm way less comp than I should be. I don't really want to spend anymore money on this for now at this point so going to call mmr and give them a hard time, see what they can do
