Unsure of cam specs, but the engine will be a Bill Mitchell aluminum block, 4.50 bore and 4.25 stroke for 541 cu in.
Trick Flow 270s (Max Wedge ports)
Horsepower and Torque 700 HP? and as flat and high torque # as possible w/7,000 RPM capability.
7,000 RPM capability based on current tire height (25.6") and Wallace calculator 10.4 second 1/4 mile at 133 MPH 3,800 lbs. 4.10 gear.
Now I am certainly open to changes!
I may need a taller tire so as to not have to spin up to 7k, or maybe put the 3.54 gears back in?
BUT
Given the Bill Mitchell aluminum block, Molnar crankshaft and 7.100 rods, matching quality pistons-that can also handle the occasional 150-200 shot of nitrous (if I ever manage to harness the power I already have) springs and so on 7k RPM should be no sweat for reliability.
I guess the easiest way to deal with RPMs is a taller tire. If I wind up going over 133 MPH (like if I do hit the juice) I don't want to have to live with the bad manners and maintenance I ASSUME would come with a 7,500 RPM engine.
These are questions as much as they are projected parameters. I'm trying to paint a picture of what I will wind up with so I can get advice on lifters and maintenance.
Back to my question:
What is the best lifter so as to not wind up with needle bearings scattered throughout my oil pan, or having to rebuild lifters, etc. and still choose a lifter that works with the cam that works with everything else? I don't mind an "annual maintenance weekend" if neccessary, but I have to be honest and say I'd rather not have to spend a lot of time under the hood.
