Your built trans truck will be faster hands down with good tunes. If your buddy is solid stock trans then it will slip before it wins haha. I have personally been beat by a LBZ with trans go Jr and water/meth, wasn't super close, but about a truck length. And thats only if his trans doesn't slip Now that I got my upgraded tunes I have the feeling that this isn't going to be the case next time Dman777 may beg to differ but we plan on finding out next time we go to the track

Dustin works for Rob I'm pretty sure I'd take his word for it!!

Just for the record, when I said the lb7 is "more capable" I meant in stock form (minus Trans). The lbz has a better cp3 but slightly lower flowing injectors, the lbz also has a better turbo to begin with, it's a 50/50 trade off on which can make the peak hp..
The top 50 quick dmax's are filled with lb7's because most people cannot justify taking a $20-40k truck and dump another $20-40k into it to set records and only drive down a track. Typically speaking, due to the age of lb7's, they are cheaper to buy than the other engines/years with similar mileage, condition, and options.
