Wanting either a Aluminum or Iron ( koleno ) 4.500 bore. Who and which is better Indy Max or KP? Stroke of either 4.150 or 4.250. the car is about 2800lbs. Id be using my Indy Ezs with max wedge openings and Indy single plane w/1100 E85 Domin. and solid roller, Milodon external oiling. What is a good engine builder or company that can build the shortblock? Im guessing around $9000 for an assembled shortblock. Plz share you experiences and thoughts, If your asking why am i doing this? Cuz i want to build an ultimate short block and be able to grow into it as the need for more HP is neeeded or wanted.
