515 hp 253

[HK1837]

Yeah, but not bad for a "boat anchor,thong slapper, starter motor etc etc. if Holden had thrown as much money at their own V8 as GM had at their motor I think no one in Australia would have the interest in the GM engine. Such a shame really.

Anyway, 515 from a 253 for every one who asks if a 253 has any potential is the answer.

I agree it is impressive, but the only reasons I can see for it are: because you can, or because of an arbitrary limit you had to abide by eg engine size limit in an LJ.
