Alright so a few questions here.
8.5:1 for L67
or
9.4:1 for L36
I can find either cheap enough and easily enough. I've always thought of higher compression as kind of "free" HP, so which block to go with?
I have a set of MLS gaskets already, use all the layers or leave one or maybe 2 layers out?
What about the heads, I plan on dropping a set of L67 heads I have off at a shop to have them checked out.
simple valve job, magna fluxed, new guides and seals, machined to prepare for a ST5 cam, and how about having the heads milled to jack up the compression?
Should I leave everything alone and use low comp block, all the layers of the MLS gaskets, and NOT have the heads milled?
or is it worth it to jack the compression up a little more around the 10:1 or higher for compression?
Keep in mind this engine will NEVER see pump gas only E85 and likely nitrous too. part of the reason to use the l67 heads is with a NA lower intake I will have an extra set of injector holes ready for nitrous. Its all going in a stupid light car so at the very least id like to make 500whp/500wtq is the goal.
Hoping the turbo guys will chime in on this.
