Fuel injector question
I am trying to buy new fuel injectors and i am unsure on what fits in the ls1 cars. I want to get a good set of like 36lb or 42lb injectors. i was thinking of just buying the stock cobra injectors but i do not know if it fits.

The L67 and L32 injectors are 36 pounders and fit perfectly. Can get them at a dealer or anyother good GM parts place. Why are you getting bigger injectors?

apparently i am just about maxing out the stock injectors and my car seems to have a loss in power somewhere so i am getting a bigger maf and injectors.

Did you have the car on a chassis dyno? If so, what did your results look like? (hp/tq/ & air/fuel ratios)

IIRC, injectors are somewhat like spark plugs in that most have a common thread size. Might be wrong but I'm pretty sure that GM and Ford can be swapped...
67 Camaro: K-K + 797-z (look it up), 454/Th400/4.10 12-bolt = 6mpg, PS/PDB/PW tilt, tach, gauges...
2005 Corvette LS2/M6 Magnetic Red Metallic (What else would it be?) w/ Cashmere interior
2002 Z28: NBM/Tan, MTI smooth lid, smooth bellows, !AIR, !cats, 1-3/4" QTP SS LT's, 2-1/2" TD's with X-pipe, MagnaFlows dumped at axle, custom welded SFC's, MidWest Chassis body mount adjustable T/A, 3400 stall, 3.23 gears (was 2.73). Tuned: 343rwhp/357rwt (before TD's). Best: 12.559 @ 108+, 1.73 60' @ 3500' DA w/MT ET Street DR's.

car has been on a dynopak which bolts to the hubs. it made only like 356hp and 364tq which in my opinion is very low for a cam only LS1 with full exhaust and a stall

even without the converter a cam only ls1 with full bolt ons should make way more power and my AFR is 13.4 I believe

That seems to be a decent AFR - if you put more injector in it, how do you intend on moving more air? Originally Posted by SOMTRANSAM

What gears do you have? Have you watched your fuel pressure when the injectors are supposedly maxing out? As mentioned might be racetronix and hot wire mod time

M/T DR's to the rescue! That alone cut my short time by .2+. Turned it into an insta-hook at the right stall speed... Originally Posted by FasstChevys
