looks hott
are you stoking the motor? as well 522 cid
vd..
Not a stroker. It is bored to 4.125, which with the stock stroke takes the displacement to 529 cubic inches. I didn't want to compromise stability at high rpm, so I decided that the shorter stock stroke was likely better.
Nice setup. Are you retaining the stock main and rod bearing dia? That would play a bigger role in high rpm life than stroke.
Billet main caps and arp studs are on the way as well? I hope.
Are you planning on doing any oil system mods? dry sump maybe?
When they line hone the crank mains, be very very VERY certain how far off the centerline moves, and be damn sure to properly setup the oil pump tolerances after the line hone.
All that motor, it's gonna be time for a TT
Billet mains and arps are part of the build. After going back and forth, I decided to maintain the stock diameters. I'm not really building a high rpm motor, I just didn't want to do anything that would take me the other direction. We are very conscious of oiling issues. No dry sump (couldn't find a system that allowed me to keep my air conditioning) but am installing a 3 quart accusump.
My goal is not maximum power, so I'm keeping it naturally aspirated, and pretty lazy. I want maximum durability. To that end, I'm not running super high compression, and we will run it with a conservative tune. I want to be able to run long track sessions and otherwise abuse the car with no worries about the mechanicals. Don't know what the power will be, but am guessing it will be north of 600 even though we're leaving a bit on the table.
