Engine Specs??

[Susanne]

This is kind of embarassing... but I really don't know the answer, and can't find it.

I received a '17 short block that was babbitted, but missing literally everything else. I was going to start sourcing parts, and all of the sudden, it hit me...

WHAT were the "standard" specs for a T engine? I have no idea if this block is stock or 40 over, the crank saddles are set for shatever standard is or 20 under... So I went a'lookin', and realize I could not find ANYWHERE in reach what the "standard" specs were on a T enngine. Pretty embarassing, eh?

So... could someone point me to the "baseline" specs for a T engine, transmission, etc? I know the answer is out there somewhere, but... um... yeah. Can someone point me in the direction to find things such as what's the crank journals, bore & stroke, Cam journal sizes... the whole maryann that I could pull up on a modern motor from someplace like Alldata, but somehow is eluding me when looking for T stuff.

Much thanks...

Scroll down, there’s about everything here...
From Mac’s, google search...

Just be careful on Mac's piston specs, they are for a cast iron piston although a foot note states that the split skirt faces away from the cam, that is a aluminium piston, to set the ring gap on a aluminium piston at what's listed you will have an engine that will lock up.

Here's Lang's version. See page 299.

I am NOT a machinist by any measure, but I have a question. The specs listed in both Mac's and Lang's indicate a cylinder bore as 6.752" long but neither include the stroke in the data. Why? Isn't that a useful bit of information?

Henry,
Not sure why they wouldn’t show the stroke spec.... but it’s 4”

The booklet "Engine" published by the club has this information. It is very useful in maintaining or rebuilding the T engine.
Bore diameter=3.750 length 6.752.
Crankshaft main bearings length front 2" center 2 3/16" rear 3 1/8 " rods 1.505" diameter of all bearings 1.248". Stroke 4"

I recommend the book.

that would be a spec related to crankshaft.
