the engine is a 4.3 and a rod let lose. I went to the junkyard today but there was no good small blocks to start with. I have a good start to a sb with a lunati 290/297 duration 490 lift cam, 2.02/1.5 heads *started life as 1.94* and torker or a rpm intake. I built a sb two years ago and im starting over so that is what im left with and the engine only had 3000 miles on it.
