how about a ka crank : )

 

The crank main bearings on the KA are much larger diameter than the L or Z series so forget that. They could be machined down, but why not use a Z24 crank? The mains ARE the same as an L.

 

It can be done by trimming the throws and relieving the cylinder skirts but this seriously affects the rod length to stroke ratio. Effectively the shorter rod on longer stroke pulls the piston more sideways as it nears the half way point down the cylinder. Friction and piston scuffing can result.

anyone?

I think there is one on ebay

That's a Z24 crank. Will only fit the Z24 block. It's simply a truck crank... there's nothing performance about it.

 

His adds are either misleading or his knowledge about Z cranks are limited to what Jason Gray has learned about them. At best, it would fit an L20B or Z20/Z22 motor built after '75. Even then, not without major alterations to the block. This crank will never fit a 510 car's L-16 period. Won't even fit the L-18s.

 

Here's another:

 

No mention that this will over heat the stock coil and likely fry it. EI dizzys need an EI coil. Imagine how pissed someone would be thinking this is a simple swap?

Imagine buying these and finding you have to over bore your 510's L-16 or 240Z 3.5mm!!!!! That's 0.138" Even the L20B in your 620 would need about a 60 thou. increase in bore.

Yes you can stuff it into a l20b block or z22 block thats how you mak a lz24

We are in agreement. :D

I have a l20b from a 1978 620 and a l20b from a 1980 720

... not without major alterations to the block.

MAJOR grinding of the throws and block to wedge it in there.
