Philistine MC. Please help me
1st time having a engine built, installed and I fill like a general contractor.
I put in a iron 6.0 block the engine builder said it's a 408. The list is long but if anyone is interested I will list all the parts. I am doing the final dyno/tune in 2 days. I was told to expect another 50 to 70 hp, above what I currently have. I don't know what I have because my engine guy is a few hundred miles away. I gave him my cars computer when I dropped off all my parts/ heads, oil pan and so on. The car is a beast. Just wish I could run through all my gears at high rpm.
