Find some GEN 4 connnecting rods, those will support 800-1000hp if you need them to.

The 1999-2004 rods are I beams and will bend if something goes wrong or because they just want to sometimes lol.

 

the 4th gen are a direct drop in I assume?

 

K1 or summits rods (I believe they are k1) would be a good choice.

 

Yes they are.

 

I need some advise from you gurus out there. I have found a piston an rod combo deal from trick performance. However I need some guidance. The pistons that are selectable while picking my options for the combo and are the same bore as my current pistons are -2.2cc flat tops. When I looked up the specs for my 99 lm7 it says they are +8cc and they are dished. I have 862 heads with stock 61cc chambers. My mls head gaskets are .045-.046 compressed. Im trying to find out what this will do to my compression ratio, I know everyone says to go with lower compression when running boost. I will be running water/meth or straight meth with 93 octane this round to be safe. I used a calculator and my results came back to like 5.4/1 so I’m doing something wrong. Stoke-3.662, bore-3.780, gasket .0045 compressed, chamber 61cc, gasket bore says up to 3.905 and deck clearance is .007 correct? These are the specs the calculator asked for plus piston volume which I tried +8cc like the spec sheet showed and I tried 8cc. I used this to make sure the maths were correct but got a super low compression rate. It should be 9.5/1. This is the link to the package I’m referring to https://www.tickperformance.com/hot-...s-big-savings/

 

I think it’s important to note that this is a daily driver and I plan to tune for up to 16psi but will most likely have it set to 13-14 psi 99% of the time.

 

Depends on the calculator you are using. use this one. Engine Compression Ratio (CR) Calculator

 

thank you for that! So I probably don’t want 11:1 with boost huh? Maybe I can add some 799 heads. That would get me back to 9.8:1

 

That be around 10.5:1

 

I would probably do 317's milled to 68CC

The milled version
