Selling leftovers from my engine build - I ended up getting an entire new short block so this stuff is just sitting on the shelf.
Crank is an original Boss 302 forged crank that has been heavily modified - machined to zero balance and Chevy 2.100 rod mains. The crank is balanced to the Diamond pistons & rods listed below. The old motor spun a few main bearings so it needs to be machined. It has standard mains now so it can co to a thicker bearing. Balance work was done by Detroit balancing - I have the receipt.
Rods are Carillo H beam with SPS bolts - these are a longer rod tha stock 5.09. I have to pull the specs up (its at the shop!) for the length but the pistons were both custom made for this setup. Again, these have smaller Chevy rod journals ends for less weight.
I have two sets of pistons - first is a set of custom forged JE's from a previous engine and they are 4.020 and for an inline valve head. These were made specifically for this crank and rods but are heavier than the Diamond ones - plus I had the crank re-balanced for the Diamonds. Nothing wrong with them - they are in great shape.
Second set of pistons are Diamond - I had these custom made in late 2009 as I switched to a twisted wedge head. These things are beautiful! They are currently on the rods and have tapered pins. They are fully CNCed on the back side for reduced weight - see pics. The also have the anti-detonation groove and all the other cool stuff diamond does - really a Quality piece. They have total seal rings on them (1/16, 1/16, 3/16) with very little use - I don't reuse rings but they are included. These were made for a blown setup and have a 9:0 to 1 comp ratio with a standard TFS TW (I think they are 61cc?) chamber. These pistons are for a 4.045 bore (309).
I have a ton of money in this stuff (over 2K just in diamond pistons & rods!) but hate seeing it sit on the shelf and have no immediate plans for it. I would like to get $1000 for the whole package but would be open to any kind of trade and offers. This was my first "good" rotating assembly setup and I want to see it go to a good home!
