zukinut,
I haven't answered this post before but after building a 410ci engine for my 57 Fairlane I will tell you I am tickled to death with the way it turned out. I can get at least 18mpg on a trip and I can assuredly enter the 13 sec bracket through the quarter mile. But, the engine was engineered to accomplish what I wanted. I listened to my most knowledgeable associates on this forum to a degree. I actually took most of the advise when building my engine. But, I didn't go to extreme's that would make the intended use of the car unattainable. That's what you need to think about. Think of the budget you have and then think of the engines intended use. It makes no sense to try and put 15,000 miles a year on an engine that has 1000 HP, can't sit in traffic over 15 sec without overheating and gets 4 mpg gas consumption while idling at 1500 rpm just to keep it from stalling. Bigger is not always better. Like I said, my engine is exactly what I was trying to accomplish and it still costs be $8500 for parts and machine work with me having the block to begin with. I feel like that is great for what I got. I'd have been really pissed if I'd have spent $3000 on an engine build and then been dissatisfied with how it turned out. Good luck and congratulations on the new addition to the family. Jim
