Re:The wave of the future for pickup trucks?
The problem is not one of the entire block not being up to the task but being able to fasten main bearing caps down into aluminum solidly. Solution make the block out of aluminum but make iron main bearing saddles... the "top of the main bearing circle" out of CNC machined forged steel billet so you have main cap bolts in a solid chunk of steel. The bolts can't pull out and the main bearing saddle stays round on both sides of the crank. An all aluminum saddle can distort when pulled on by the main caps. So put steel where it is needed which is a better grade than CGI. Then use AL where you can.
My guess the AL block ford (consider the source and 6.0 CGI engines
) was using was a non reinforced AL casting.
Take 24% of the weight off a cummins ISX drive it 100k OTR a year.... Do the same with a CGI ISX same load in the trailer. Tell me who used less fuel.
Also 210# in the case of an ISB is .2 to .3 seconds quicker in the 1/4 at the same hp output.

in heavy vehicles like trucks where the engine is a lower % of overall weight and higher torque is required over many more miles, it's hard to imagine al. engines being cost effective any time soon.

Just for because Ill make this remark.Yea Honda eng. go between 150 and 250000 miles but the heads finally warp. ( I have owned at least 5) And when we talk about dragsters every 50lbs saves a pt. in time they do not care if the eng. is replaced every run or every 3rd run,thats the nature of the beast!!
I think the' wave' of the future is still being ignored -lots of ceramic, no wastfull water cooling sys.Allmost no heat loss. As for the aluminum eng. ,it"s just a bandaid ,a fix for now..It would be better to take the heat and convert it to pwr rather then try to figure out how to jerry rig your basic platform to stay togather.
