700HP 383 Buildup

What does it run in the quarter mile?
What car does he have it in, does the car have any fiberglass on it?
I don't know if this is the case, but I've run into so many so called 500-600hp small block Chevys, then they get waxed by a low 13 second Mopar.

My thought exactly. A similar post on a differrent website had a response that said something like this " the fastest way to make a 10 second car run 13s is to take it to the track."
Simple physics can tell you if he's close with the figures. weight of the car and mph, and gearing is needed, then we can tell him what it's actually doing. I have seen some powerful small blocks, naturally aspirated, that can make those kind of figures, but they dont grow on trees.

I'd just hate to see you over spend, or be disappointed in the result.
