I think its time to sell my prized possession. I have a brand new 331 Dart Iron Eagle Sportsman Block that was built by Probe Industries also known as Coast High Performance (CHP). The block started off as a brand new Iron Eagle Sportsman which is a 4 bolt main on 2,3,4 main caps. It was built for forced induction in mind so it has all the best go fast goodies. Its a 4.000 inch bore with Probe SRS light weight Forged Pistons with Molly File Fit ring set and Tool Steel wrist pin (upgrade). The block was machined for a 331 and has a 4340 Forged Steel Dominator crank 3.250 stroke, Lightweight 4340 I-beam Forged Steel connecting rods (length 5.400) with bronze bushings. New rear main seal, cam bearings, champhered rod bearings, champhered race main bearings, oil filter adapter, cylinder head dowels, pipe plugs, cam plug. This block can handle 1200hp and the internal can also keep up. Has internal balance of 0 (neutral). I have nearly $6000 invested in this short block and cannot continue to finish off. I will sell for $5000.00
