Cube root is the inverse of x^3 (x^3 is "x cubed")

Thunderbolt IV trigger voltage question

What voltage should the Thunderbolt IV module supply the distributor? I am getting about 4 VDC, and the trigger is not switching when I turn it.

Re: 425-470hp Small Block??

Like you say (Ratman), I wouldn't use a forged one either for those power levels.

Put a BIG blower on it, nitrous, etc, then I would look at forged.

even then, I've seen stock 400 cranks with a...

Re: changing sbc's from late to early style

Even if you have the correct "triangle" couplers, if there are signs of wear on the splines, replace them. Might as well do it while you have the motors off.

Oh yeah, make sure you get 14"...

Re: Chine walk question

Chine walking can be 'controlled' to a point. On hipo outboards, they have hotfoot throttles and trim controls on the steering wheel for this very reason.

Re: 350 LX motor build question???

You might see those gains with a full roller rocker. Those gains quoted are usually high and also taken at very high RPMS, where the full roller rockers improved accuracy pays dividends.

Re: educate me on small block chevy flywheels and dampers

You can go the junkyard route with that, but I'd look at new one, or one you know is in good shape.

Re: educate me on small block chevy flywheels and dampers

Yessir. The bolt pattern is the same on all SBC flywheels. Check the splines on the coupler, if they look worn at all, I'd replace since you already have the motor out.

Re: educate me on small block chevy flywheels and dampers

Don't know part #'s, but you need a 14" 2 pc rear main style flywheel off a 350 or any SBC besides the 400. The 400 are not truly balanced, they have a counterweight for the 400 crank. There are...

Re: Q jet question, 454 750cfm on 350

From my very limited experience with qjets, i think one setup for a 454 would actually be too lean for a 350. It can be made to work, of course by rejetting it, new metering rods, etc.

The oil actually protects the fibers from...
