Hi, I'm a new girl here. I've rebuilt a few engines but I'm by no means an expert, and I appreciate any constructive criticism etc.
I'm building a 212cc predator hemi engine for high compression and high rpm (9k peak would be OK) to run e85 only.
I've milled the head so the combustion chamber is down to 17cc, and ported intake and exhaust.
I modified the intake rocker only so it's a 1.27 ratio intake / 1.24 ratio exhaust.
I currently have the stock cam but would like to upgrade to something harder.
22# springs.
Billet +.020 rod
Fly cut piston, waiting on rod to be able to check clearances..
I want a Billet flywheel, and I'll get one before I even try revving it way up.
Compression currently is calculated to 11.7:1 with .012 head gasket but may need to go with a thicker gasket to assist in valve clearance.
Vm22 carb kit
Open header
Removed oil sensor and governor
Anyone see any issues with my current intentions or build? I've never tuned for e85 but I've had many a experience with jetting carbs. I'd appreciate good information from some experienced builders. I'm not sure what timing I should go with either. Thanks!
