Default QF 750 or 650 for stock ls1

decided against e85 for a few reasons and have my tax check back and looking to get this fuel system setup and get this car going.

stock 346 ls1 with headers, msd 6010, vic jr intake

future plans for next season may include a cam dont plan on going big motor for a while. would it be worth it to get the 750 now? or just get the 650 and run it until its not enough for when i mod the motor, which probably wont be this season. car is a track only car, mostly bracket racing with a little index. these are my two choices, someone tell me if im thinking clearly lol

A 750 is the size most commonly used by guys on this site with the 5.7L and up LS motors. GM recommends them for their crate motors. 5.3L guys with stock valve trains and dual plane intakes gravitate more toward the 650's.

Throw in track car with a single plane intake and the choice becomes more certain.
