V6 vs V8

Here in Australia I drive an 99 model ls1 powered Holden.(yeah I know but it was my wife's daily driver and I would rather kill it than my mopars).

At the end of the day it's still a pushrod v8 with similar capacity to a 318/360 but it makes a genuine 320hp and does it with a very small duration camshaft, around 200@50. To me it's all in the heads and what they flow compared to an old school LA engine and it's hydraulic roller cam with its ability to run high lift with smaller duration. The high compression ratio and knocks sensors help too.

What I have noticed is though that having the bigger ports and better flow sacrifices low end torque, put your foot in this thing down at lower rpms and it will pull away smoothly with the EFi but it has no torque compared to my small block mopars.

Having a t56 6 speed with close ratios and 3.45:1 gears does tend to mask the lack of torque, put a 3 speed auto in it with 2.92 and 3.23 gears and it wouldn't go anywhere fast!

Put some nicely ported edelbrocks with hydraulic roller cam on a 318/340/360 and I dont see any reason why it can't make the same power.
