When Is A 3k A 4k ?

[Andy43]

I have a 3k engine stamped 3k, however once the sump is remove the crank has 4k stamped on it.

I checked the deck and yep the deck is 10mm higher than a 3k, The stroke is 73mm.

Are there any other marks I can look for ????

Cheers

that must meen you have a dodgey 3k :(

 

probably someone cut off the engine no. and glued it onto the 4k to get the 4k in there sneakily

maybe check for signs of tampeing around the engine no.?

Hi Andy,You may have a 3K block with a 4k crank installed ,Making it a "3K stroker".Great for 1200cc class racing.This can be done using lower deck height pistons.Remember he who cheats the most with out getting caught wins. :(

Except the crank has 4k stamped on it :(

I suspect you may be correct, the problem is in our class of racing they measure the stroke when the engine has its head off, you then put the head on they install a seal, if the seal is broken you cannot race.

Bugger.

Remember he who cheats the most is the biggest looser regardless, weather he gets caught or not. :(

 

Blockheight and sump bolt pattern are easy ID signs of 3k <>4k

Deck-height increase would mean that he doesn't have a 3K block. I'm joining the "3k number on a 4k engine" crowd.

In saying that though, I'm a big fan of the great Smokey Yunick, who ran by the philosophies "it's only cheating if you get caught" and "the other bastards are doing it 10-times worse"

[Andy43]

Down and dusted I think 4k rebadged for what ever reason to 3k.

For the record

The engine number.

 

The crank

 

The deck high note distance between water pump bolts and block face.

 

For good measure here's what a 3k should look like.

I'm pretty sure the "3k" should be in line with the rest of the numbers, so deffinately looks like a re-stamp. Maybe sell the motor to TWF#14...... he's right into cheating!!!! :(

Wrong, mine is lined up exactly the same as that.... I still think it is a re-stamp, but I don't think he stamped in the wrong spot.

Because you constantly start pointless, well covered questions, normally about heads and how you're trying to cheat your way to winning.

 

Except it - You need to use a 3k for speedway...... that included the 3k head. So stop asking RC members to effectively help you cheat.

 

 

I think I speak for all of the admin/mods (including the "f@$k stain" who locked your thread yesterday) when I say we're sick of your shit. Shape up or ship out. :P
