Alreight guys I searched and didn't come up with a whole lot, basically I bought the Goodwrench LO5 motor (part #12513151)meant for the fleetwood and caprice from scoggin-dickey. I'm using it to replace my tired 305(started ticking the other day). Anyway down the road in the next year or so I plan on getting rid of the swirl port head and going with a Vortec head setup with probably the LT4 Hotcam. What I need to know is what would be the best thing to do right now for the motor? Should I run the 19 lb injectors from the LB9, and will this be ok or cause possible problems from a lean condition? Or should I go ahead and put better injectors in now? I'm thinkin of going with 24 lb injectors, think they will be good, or overkill?

PS I already know to get the ESC and knock sensor for 350. And chip. However, if I can stick with the 19's for now, should i leave the 305 chip in also to compensate until I get the bigger injectors?
Thanks in advance

 

Let's try the good folks over here.

 

If it were me, I would consider the chip I am running. If you get 24 lb/hr injectors, can you get a chip burnt cheaply to adjust the injector constant? How about 22 lb/hr injectors to work with the stock chip?

It never hurts to go with the 24 lb/hr injectors...they should feed your setup just fine. The key is how the computer will see the injectors. You don't just want to plug in the larger injectors, as it will run rich.

 

I think the 19 lb injectors and stock chip will be adequate for a stock cammed swirl port headed 350. When you switch heads you can do the injectors too.

 

Do I need the ESC for a 350 or is the 305 one the same?

 

Insomniac...that is a bad idea to run a stock 305 chip on a 350.

Whats wrong? Nothing except for the VE tables, displacement, part throttle, etc.

Anyway you look at it, the chip should be changed so you don't damage your new engine.

If it runs too rich, you can wash out the rings...and possibly bearings too.

Why screw around with it when you are already spending $1600 on a new engine?

 

I wouldn't run it at all without scanning it with any stock chip,305 or 350, but the MAF will do the majority of the fuel adjustment. The VE tables don't adjust as much on a MAF car as it does on a MAP, and it should run fine. I think it would be wise to scan it though when you get it going. The VE (Volumetric Efficiency) has more to do with the engines ability to move air than displacement.

Sorry, I was thinking of my own car...and I just hung up on LO5. Oops.

The scanning is a great idea and the 350 chip needs to be in place with the correct injector constant...once again, why play around with the health of a new engine?

 

I have the same engine in my 87 Formula....
With no modifications except for the L05, the engine ran fine, much stronger than the aged 305.
However,
Scan data using Datamaster showed BLMs higher than 128 suggesting the engine was running lean until corrected by the O2 sensor. Also there was a lot of spark retard at WOT.
I burned a simple CHIP adjusted the injector constant until the BLMs were mostly corrected. I still had spark retard at WOT, but not as much.
I changed the knock sensor to the 350, but it didn't do anything.
The ESC module is still the original.
I had a rough idle, so I added Accel 24 lbs injectors. The engine runs a little stronger, but still has a slight rough idle.
I just removed the intake manifold and found the PVC vacuum fitting loose in the manifold, before I removed it. Should fix the idle.
Summary,
Engine will run fine with no modifications from the 305. Don't waste your money until you can get scan data and burn a chip to adjust the fuel and timing.
