would not applicable lol... it only makes the power it does due to rpm , which means that small of cubic inch it needs alot of love separation angle because you cannot stuff that much pressure in to a small cylinder at low rpm due to turbo pressure is low at low rpm, now add to that tire rotaional rpm to gear ratio to torque converter multiplication rate.... look at how much it cost just for a true tranny to handle that level of power constantly.... the oil squirt on piston underside is nothing knew at all... notice he used a thick height piston to absorb the heat generated from compressed pressure of boost,bhe used a big heavy rod because you need more weight to handle the high rpm, it's .5 longer than even the best ls sbc rod and probably 2xs heavier

I believe your little buzz bomb boat motor with dual four EFI + NOS in a chevette could be exciting and get decent gas mileage and extra engine life as we know EFI has never washed out rings or bearings ....BUILD IT AND THEY WILL COME ....and if it becomes popular and I think it will you will have the opportunity to build a specialized NRE optimized EFI intake manifold ...tada ..there I just made you another million ...like lee Marvin said to the ladies above the bar in "paint your wagons" " i give you the boy.. give me back the man"

How did this setup hold up?

[@kencohagen4967]

Way back when, guys used to run the 283 because of the crank pin overlap between the main and rods. The other thing is that they had small journals, which allowed for more meat around the bolts and thicker walls on the mains when compared to a four bolt block. The distance between the outside edge of the main cap and the inside of the main journal is thicker than a four bolt 350 block, which gave it more strange hope. The rod ratio was better, the Pistons were lighter and all that added up to a motor that would rev like crazy, and make killer horsepower.
