Those Holden engine crankshafts have any crossover to the Chevy or Pontiac six's they built here in the US?
No. The earlier Holden 3.779" bore spacing engine was what the 1955 to 1960 Vauxhall engine become, but was US Chevrolet designed. The US in line sixes are all 4.40" bore spacing. The GM 4200, 4.05", same as the Cavalier/Cimarron engine, if I recall. Opel Family II OHC based bore spacing.
Hence the 4.08" bore spacing was a 100% GM copy of the Ford Falcon engine, just like the 3.78" inch bore spacing 1951 Ford Zephyr/Counsel/Zodiac was a 100% copy of the 3.78" inch 1948 Holden Grey Motor (1936 Chevrolet/1955 Vauxhall small car design) bore spacing engine.
And kind of like Dick Ronzi's Chrysler D series 4.46" Bore center Hemi intake manifold on the Cross flow OHC 240/300 4.48" bore spacing BIg Six
That would be pretty cool,a 4.5"x4.5" bore and stroke 429-6. If you go for for it I will be watching your build.

Copy is not nepotism or theft, but a "Devine sense of respect" in my humble opinion.
The Boss 302, Cleveland 335 and Lima 385 engines got the best rocker sled fulcrums and retainers from Chevrolets Big Block Mark IV 427, after all.
as for the Medium deck 188/221 corrections and details, many, many times raised from 2007 to 2018. The wrong bitz in blue, with a post further below on the specific's. If it was the Wolf, it would've bitten ya'll.

Ok, as i am confused with these little engines i will outline what i am trying to do, my car is a 1967 XR wagon, original 200 super pursuit with 3 spd manual and 75 series rear. I wanted to upgrade relatively cheaply to hot little six, C4 auto and a 78 series diff. So far i have done this to the...

I’ve been searching the forum for information regarding the 221 Stroker article in the Tech Archive. I haven’t read everything, I’m sure, but what I’m wondering is if there is anyone here on the forum that has actually built one. There are a number of threads that discuss what parts and offsets...
