I am wanting to know the stocke size injectors for a 94 lt1 and sre the injectors interchangeable wit hany other cars? Also if I change them will I need a new mass air?

Can I use a set of 4:10 gears wit ha basicly stock car with automatic transmission?

 

Stock injectors are 24lbs. I am pretty sure that you do not need a new mass air, but it might be a good idea.

As far as gears go, most people with automatics go for 3.73 gears, as opposed to 4.10 gears because of highway cruising rpms would be pretty high with 4.10, and at the track most people seem to see the end of 3rd gear at the 1/4 mile mark. M6 cars on the other hand usually go for 4.10, but they have 2 more gears than us

Stock injectors are 24#/HR (programmed as 24.9#/HR in the PCM). They will be fine up to about 400flywheelHP. Over that, you would need to upgrade and reprogram the injector constant in the PCM. You sound like you are more familiar with M'tangs where they go to bigger injectors and need to swap to MAF to sort of trick the computer to provide the correct fuel vs air. You don't do that on LT1's. You put the correct injector size into the PCM.

The stock MAF is fine for stock setups, and even relatively heavilly modified LT1's.
