The thing to me is the LSx is produced in the US with a population of 300m people. There are so many people developing heads, cams, induction etc etc. I just can’t see how an Aussie product will ever compete especially on price HP for HP, it just comes down to market size. If I was making that block I would be seeing if it’s feasible for it to take LS heads. That would open up a world of options. Good discussion btw.
Cant be developing a holden based block and then tell them, ” hey you gotta run some 241 heads” Nothing wrong the Holden heads. Believe it or not there are certain blokes that can push a genuine 700Hp + through the cast heads.
but you can develop a Holden based block that takes chev internals?
TP Holden cast iron block = $6600. Anywhere out to 443ci. This block uses all Holden gear, the big paw (alloy up to 560ci) is filled with Chev components.
They did it for the SBC, designed a block that could take LS parts, why not give it a shot.
