Ddgonzal nice to know :)

So im wondering what sort of power to expect from a stock a10 supercharged engine with just headers. Would anyone be able to give me a hp figure?

So are the limitations with a 3 bearing crank only the rpms? If u say supercharged an a10 but didn't take it over 6000rpm, would it have no issues? Also, being that it's only 1000cc's, would u be better off only using an a12 round port head?

It's a 1968 ute.
All I know is the last owner said he changed to a 120y diff

I'm not sure I fully understand what your saying. Brains in melt down haha. So are u saying to basically make a cradle?

Well im supposed to pickup an a10 engine tomorrow
I believe my diff ratio is now 3.9. Was told it has a 120y diff center

It's not the money. It's the regulations that hold me back. What's going to produce more power easier, worked a12 or turbo a10? It's a hard question but im thinking that the a10 turbo has more potential for cheaper

I just know in south Australia that I can either go an a12 or I can supercharge or turbo the factory engine. I'm thinking a a10 turbo would produce more power easier?

Sorry to start another thread here but it's a little different to my other one with regards to going more cc's on a worked a12.

The law stipulates that im allowed to turbo or supercharge an A10 only. I know the poor a10 is only a 3 main bearing crank. What are the limitations of the a10 under boost? What would be the max rpm etc? Would a oval port head be ok to use on it or would it be better to stick with the a12 round port head? Has anyone done it? I'm guessing an a10 turbo will be more power over a worked a12 on a budget? Thoughts? Ideas? :)

So a a10 using a12 pistons. a15 head or is it best to use a stock a12 round/small oval port? Legally I can do a a10 turbo which I would think would produce more power then a cammed a12. I just worry about the 3 bearing crank that's all. What are the limitations of the a10's 3 main bearing cranks?

I'm pretty sure my diff center has been changed to a 120y one (old owner told me that). I am allowed to boost an A10 legally (has to be the original type motor so no a12+). I just dont think the 3 bearing mains would like it all too much?
