The above link has some great information. But dont take everything in here as the "word of god".
Just my .02$.... You should look for someone to port those heads and get some upgraded cams, springs and retainers. For 'All-Motor' engines power is in the heads. Turbo cars are the just with boost. Not 100% but close. Nice build.
Not to start anything but, to just chine in. Oil pressure at any RPM depends on alot of factures, including what oil you are using, tolerances, motor type, temp, ect...
I have ran E85 before. Mainly when it was 3$ a gallon less then 91. With E85 a good rule of thumb is to run 30% more fuel a it like AFR around 8-8.5:1. hope this helps.
BTW I never ran stight E85 just a 50/50 mix.
Not to keep this going BUT, for an 'inline' engine... the only real way to see if crank needs to be balanced is to spin it and see how much it is off from side to side, and how much are you willing to live with. "V" engines are a different beast, like stated before.
Just my 0.02$ but you really should use the correct size sway-bar bushings. It will take a very long time for them to "wear down" even longer if they are urethan. (SP?)
I had balanced my stock flywheel, pressure plate, crank and pulley together they were within 2gs when we started (not to bad). Then we switched out to a 9lb fidanza and we were 20gs off (on one side). (Thats bad) So ya everyone should rebalance everytime they change something on the bottom...
