Sagacious said:who makes the best lightweight crankshafts? im looking to use one to make more hp out of a heavier vehicle i may also use to tow my trailer. is it a good idea to use with such an application? i was thinking of maybe a 40lb crank.
Yes,Sagacious said:but my question is will the ultralite rods/pistons and crankshaft take as much of a beating or more than a fullweight crank? im interested in the alloys their using and how much of a comparative beating they will take. this application isnt for a 'tow vehicle' per say. it just will tow some of the time, i already have a low end torquey truck for that but sometimes i like to drive the van. the van is not a dragster but it does race occassionally. im re-doing the 460hp 383 i had in their before. some shot peen was left in the block right after is was rebuilt and maybe 1000 miles later it completly bent a rod at a 90 deg. angree and snapped the cam in half and **** blew out of the oil pan. i had a scat 45lb in it before. im wondering if i should do a 40lb this time since im redoing it anyway. never the less the van is heavy but it ran like a raped ape. right now it's got a built 700r4 and 3.08 gears.
