Stock LT1 injectors - Third Generation F-Body Message Boards

TundPortZ · 05-07-2006, 07:39 PM

hey guys my 86 IROC 305 TPI (auto) has the following mods and i was wondering if stock lt1 injectors would do well on it. The way it sits it's usually evenish with stockish lt1s

-Crane PowerMax Cam 264/274 ADV, .423/.446 @ valve
-Edelbrock T.E.S. 1 5/8 prim. Headers
-Hooker Aero Chamber cat-back
-Ported plenum, MAF, gutted airbox,filters, airfoil etc...
-all accel ign. stuff
-removed a/c compressor
-may be other stuff, dont quite remember

planning on
-AFPR
-possibly 1.6 rollers
-needs new TPS, timing...

I would think the 24lb injectors are a bit much for a 305 with the little bit of mods that you have. Im running a 350 with a higher lift cam, edelbrock performer rpm heads and 1.52 roller rockers and they seem a bit much unless I run the fuel pressure down to 35 psi.

I am running lt1 24lb injectors on my 305tpi.

It is rich and I lost 2-3 mpg but the power level and driveablity did not change.

I only put them on b/c I want to run a 125 n2o shot this year.
