I will be having my new setup built next year and am wondering which route to go? The difference in cost obviously is only the cost of the crank. What benefits would the 383 be over the 347 with the same turbo? Will there be a lot more botton end before the boost sets in? Is lowend not a problem with a single 76mm turbo? What would be the difference in dyno graphs? Its only a 950 dollar difference with an eagle crank should I go for it?

346's are doing fine with turbo applications, many people are running them - I would save the cash and invest it into the turbo setup unless you have some real specific goals that will require bigger cubic inches to meet.

Here's a video of a local built 347 on E.T. streets vs. a KB cobra, just shows you how much power a built 347 will have (it's the very last race). The black turbo Z that looks like it loses to the Cobra half way through the video had a bad clutch and it stuck to the floor when they took off, he has a spec 4 on the way. It's a built single turbo 408.

We sure the KB Cobra didn't lift?
Was it just a traction thing?

EDIT: And I screwed up, the other one that looks like it lost is a 372, not a 408. but it does have a stock crank.
