Ingredients to make killer 2.0

[90 5.0]

piston speed and the forces that go with it limit a lot of motors in terms of short blocks and rotating assemblies.

What I like to call “the rod limiter”

motor blows up, asked
“how high did you spin it?”
”All the way to the rod limiter”

A 2.5 will turn more rpm than I want to. I've seen more than one turn 11500+ and more than I can count turn over 11000. Many that are turning those rpm's are trying to get the r's down. A million rpm doesn't necessarily mean it's the quickest way down the track. I'll give you another tip, with good components these things will turn 10500 and last virtually forever, get over 10800-10900 and it's a time bomb

Fong, when are you gonna sneak your boat out and shoot it across Lake Tohopekaliga

Saw a formula sheet and curve chart at merc school that had the numbers for the forces applied to moving parts (piston stopping and starting) and how it increased with rpm's. The numbers were astounding.

Or lighter big bore than stock doesn't hurt

[Krazymaan]

248 grams

500 gram piston is stock weight. They can get lighter. If you look hard enough you can find lighter pins too. Could always go to 141 rods. I've had them as light as 327 grams

[FORBESAUTO]

Lol, no he has had the 141 rods at 327g

[patchesII]

141 rods that were 327. I run stock weight pistons, light pins and Verdi rods

I've had several sets. They're usually mid 380's.

I don't know how familiar you are with my setup or the class I run but I don't turn a million rpm. I'm much more concerned with the pistons living through massive cylinder pressure than I
am with revs

Lol, as per your previous comments those of us that see our telemetry and see a real 11k plus kinda think shi!t it turned up again need to back that off.

If he did , he'd already know that the "real" blocks come with wings in the ports ..

He's still years away from sailin a head two rows deep into the spectators ... Best way to learn is to have the ol boy come up and buy into the Calcutta while he still knows everything ...

2.0L Chrome Bore w/FI:
Back on Pg 4, Post #50, dwilfong questioned if there was a 2.0 chrome bore block
Well, I think I just inherited one with a Paul Heathman Tunnel Hull project. It came with a 2.4 "fishing" mtr and this 2.0L power-head.
Will build the 2.4 first, but want to also build the 2.0L when time and $$$ allow. First I'd like to know what I have!!!!!

The 2.0L S/N location is stamped: SHOW ENG .....I also found that the manual up/down Mid S/N plate is also stamped SHOW ENG
Yup!, the motor has no guts (pistons - rods) but does have a crank so the motor could be complete outwardly. It has some quirks: 1) no light flywheel, 2) does have the LH starter, 3) had one NOS 2.0 head and one 2.4 used head, 4) EVERYTHING but the one head is NOS! It is dirty from years of storage + the rig was used as a display boat by the Miller American race team (The boat was bolted to the trailer - not any more!).
Take a look at these pictures and tell me what I've got please. I think it represents a Champ 2.0L motor of its time period.

Yessir, here is one of the pistons I have for you

How much dose that piston weigh??????????

Hell if I know. Batteries are dead in my scale.
