Not going to make it guys, the wagon is being sold tomorrow morning.

Will a KA24E crankshaft fit in a L20b block with L series rods?

I know the crank counterweights have to have about 1/4" trimmed off and the block needs clearance. As far as the rod to stroke ratio, it's no different than a SBC 383 stroker using a 400 crank (3.76") and 350 rods (5.7") and I have literally built 100's for myself, customers, and friends. Still have one I built in 1996 and its still going.

I might just stroke my L20b block with the Z24 crankshaft instead.

Glad we made it and met you guys!

Digging up an old thread... If you still have either or both, I am definitely interested. Thanks!!

Cool. Been awhile since I bought a cam for a L-Series, who are the better companies to source from these days? Another question, my stock distributor I am running now will work with the Z24 short block, correct?

That's good to know. Think it's worth going with a bigger cam with the W58/L20b head on a Z24 short block?

Okay, I found a low mileage Z24 and manual transmission in that same tow yard from a '84 2wd 720. Was a 4 speed even offered in '84? I know it's a manual, I can see the stick. I can't tow through the gears because the truck was rolled and the cab roof if caved in. Thanks!!

For wagons? They are only about a hour from me too. Easy drive to save on shipping....

A bearing I can handle, as long as it doesn't involve a machine shop. Lol

Sounds like I need to find a 720 5 speed....lol. If I still lived in Bakersfield I wouldn't bat an eye on still using the D21 5 speed. But I moved to NorCal in a small town 6 months ago and there are no machine shops that will attempt it. I already tried with having an aluminum blower snout I needed turned on a lathe for another project. They all looked at me like I was from Mars. The source for the Z24 is a small tow yard, but I think he might have a '86 720 2wd too. The engine in the '87 has less than 100k, not sure on the 720.

Good info. The Z24/5 speed I am looking to get is out of a '87 D21. Does that make any difference on the 5 speed front case swap? Not sure if they changed any with the body style change.

I guess I am confused to why you mentioned one would need a L20b truck oil pan if it won't fit. I assume that if my current oil pan fits on my L20b in the car now, continue to use it on the Z24 block. My current 4 speed has a metal pan with a drain plug. So I guess that is a no go. What year/make/model do I need to look for a donor front case to work on the Z24 truck 5 speed? Thanks!!

Digging up an old thread... Considering doing a Z24 short block with my W58 headed L20B in my 4 speed Goon (Weber DGV). So using the L20b mounts puts the Z24 block in the same position as the L20b originally sits now? Not sure if my L20b has a car or truck pan, how can I tell? Since I already have a L20b, I figure I am half way there using my L20b head on the Z24. I can score a Z24 and 5 speed from mid '80's 2wd truck for $300. Can I use my 4 speed front case on the Z24 5 speed to make it work in my Goon? Thanks!
