Re: Lightened Flywheel

Short answer is no, it has to do with the Moment of Inertia.

I short, the radius away from the center of rotation has more effect than just the overall weight.

It is a good question though, John

Re: Lightened Flywheel

Re: t 5 tranmission

Main advantage is a full syncro modern gearbox with quieter helical gears.
Overdrive is part of the gearbox, no extra levers, switches or pull thingys.
Kind of like having the overdrive as a part...

Re: T5 Valley Machining Kit

I have the early kit for the T5 with the stock "A" housing.
It does sit back a little further than the "AA" housing and requires a special clutch disk with extension on the trans input shaft.

Re: Refitting Rods- Sunnen Hone

I think I would call Sunnen and discuss this with their tech folks.
I am not aware of any stone set that would work on Babbitt.

Some we run are 1.2 dia and used on cams with bearings larger than 1.75 dia.
Of course pushing the .500 lift or higher....

Re: Hard turning with new pistons

pat,

If it is truly that hard to turn, something is too tight.
It sounds like the crank is set correctly, this leaves just a few things to consider.

Re: TDC Finder

This is funny, while it is sold as a TDC indicator, it really is not.
