True, but everything below must survive the beating

fixed that for you....

and back to your point.... as well as having minimal "cost", OR put another way... how much hp do all the internals steal???

I'm the one who said the early crank is at least a kilo lighter... that is why I'm using the early one in my engine. I'm making over 145 whp (over 165 @ the flywheel). When I built my engine, the +EM rods were not available. That made piston selection more difficult, I'm using European 4AGE pistons, they are 10 to 1, not 9.4 to 1.

*IF* I were building my engine today.... I would remove the Euro TVIS pistons (10 to 1) and I'd remove the bluetop 40/18 rods, and replace those with the +EM rods, and +EM/JE Piston new pistons.

Here is my engine's details.....



2nd dyno run, first one in link ** below. Please note, there is over 90#/ft (measured @ the wheels) for more than 4500 rpm -
