I once rebuilt a 500 c.i. Caddy engine..

Is that a drop in for my T-Maxx or do I need to beef up the drive train first?

First you would need a special mounting bracket! :jester:

Here is a good animation that shows the difference in 2 and 4 stroke engines. http://www.stihl.ca/4mix/english/stihl4mix/default1.htm#
A 2 stroke makes 2 revolutions for everytime it fires. A 4 stroke makes 4.
Guess that would be an easy way to explain it.
It's not the way it makes compression. Most of the diesels are 4 strokes.

Actually its strokes not revolutions. Each time the piston goes from tdc to bdc is a stroke or bdc to tdc. So in a 2 stroke the crank revolves once to complete the cycle and it a 4 stroke its twice.

Crank revolves twice on a 2 stroke. 4 times on a 4 stroke.
Same amount of "strokes." The crank is what moves the piston, so everytime it goes around you have a stroke.
Count it on the little animation.

A 2 stroke fires once for one complete revolution of the crankshaft and a 4 stroke fires once for every 2 revoulutions of the crankshaft.

thats big alright but i want to see the starter battery.

Forget the starter battery; I wanna see the pullstart!

roto-start. duh! no0b!

I don't need to count it. A stroke occurs every half a revolution. Count how many times a piston moves up and down in the one given revolution. Look at the counter weight and count.

that gives a whole new meaning to the words BIG BLOCK.......

4-Stroke

Induction, Compression, ignition, exhaust......

1) Induction - Piston down from TDC drawing in fuel/air mixture - inlet valve/s open.
2) Compression - Piston up from BDC compressing fuel/air mixture - all values shut.
= One revolution of crank.
3) Ignition. Piston just past TDC - Bang! Piston thrown down towards BDC again.
4) Exhaust. Piston moves back towards TDC with exhaust valve/s open expelling spent fuel gases.
= Revolution 2

I think its more like a city block...
