That's a lot of power from a small block. You would need a coordinated effort between compression, head flow, cam profile, induction, and exhaust.
Check the catalogs from high performance engine builders to see what they're putting in these engines to get that much power.
I would think you'd need at least 14:1 compression, 300+ cfm through the heads, a custom roller cam, 850+ cfm through the intake, and custom built headers.
Lack of lubrication.
Not really. The sure tell is to pull the pan and start taking off rod and main caps.
There is a special tool you can rent or purchase from most auto parts stores. Push out the old ones and press in the new ones, taking care to get the holes in the bearings aligned with the holes in the block.
take valve covers off and then unloosen each rocker arm and pull the push rod out, install new push rod and install rocker arm back on and tighten down nut according to factory specs.
Looking at the starter from over the right front fender, connect one wire to the big, copper post in the middle of the solenoid, connect the other wire to the small post closest to the block.
Drop the oil pan, remove thrust bearing cap, loosen all the mains, use a screwdriver to push the old main seal out a little, then use the new seal to push out the old seal the rest of the way.
Put a gob of wheel bearing grease on the push rod before you install it. It will stay up by itself long enough to get the new pump in.
You can put grease on the rod and gently push it into the block. the grease will hold it in place for a good amount of time.
Stick a small flat head beside vent and push to opposit side and towards you carefully.
Run a small piece of wire down through them and clean them with carb cleaner. Then blow them out with air.
This would be the F3 button. You can push this any time that you need to replace your building block key.
Need year and model. If it's older and on the dash push/pull type there is a small button to release the switch rod then you use a special tool to turn the nut on the front to release.
