New member with a 1994 Chevy C1500 looking to swap a 16197427 in place of a 16196395

[Dolsey056]

Hi I have been working on or around cars since I was 9. Im from Rochester NY but moved to Durham 6 months ago. I have a 1994 Chevy C1500 305tbi that Im currently working on. Im used to pre 86 vehicles where I didnt have to worry about computers. right now Im trying to figure out which ECM I have in my truck because Im planning on putting an EBL system in my truck from DynamicEFI. I think I might have the 16196395 and may need to switch to a 16197427 in order for it to work without taking apart the harness and splitting it up. Im still not exactly sure. Just looking for info on whether I can swap them without having to reprogram the 16197427. I plan to run the lower end of the 305 for at least another year. So far I have only installed a TBI spacer,Headers, and a Dynomax exhaust system. I plan on rebuilding the TBi and upgrading to the 5.7 injectors and installing an adjustable fuel pressure regulator, an Edelbrock 3704 intake, and possibly a mild cam like the 249-K12-262-4 Comp cam. I just ordered a rebuilt set of 187 heads with a 3 angle valve job and am holding off putting them on till I get the Intake. I know many say the swirl port heads are junk but i'm not really interested in cranking out 8k RPM's, Im more or less looking for better power and better response when I give it some gas. It will still be my daily driver.

Dolsey,

I will be the first to just tell you straight up, that cam in a stock bottem end, stock head TBI 305 would be a HUGE MISTAKE.

The EBL system will not work with a computer controlled transmission UNLESS PIGGYBACKED.

With the 6395/7427 PCMs you do not really need the EBL anyway. The TBI PCMs have faster datalogging and are much more tuneable, not to mention run a better more advanced code.

The 61 lb/hr 5.7 injectors and adjustable regulator is a good idea. I would consider using a remote mounted bypass style regulator and a block off plate in place of the OEM regulator. Also consider a set of flow matched 61 lb/hr injectors.

I would look into the Crane Energizer 260 or 272 grind instead. You will notice both are single pattern cams. The TBI swirl ports LOVE single pattern cams. The cams are also tighter LSA as well as advanced. Both of which bring the RPM for peak HP and peak TQ lower and the peaks closer together, taking advantage of the swirl ports torque curve. With both cams (especially 272) you can tell there is a cam in the engine with a slightly lopey idle at 700 rpm, but both have a high stable vacuum signal. My 9:1 305 with the 272H10 was pulling nearly 17 in/hg unloaded at 750 rpm and it was steady. Idled 600 rpm in gear rock solid with 14 in/hg on the gauge.

Okay So I will hold onto the heads for now until I possibly either bore out and rebuild the bottom end or just start out with a 350 block. So pretty much keep the 63965 and how hard is it to tune them? is there a different programmer I should look into? I have browsed this site many times and recognize the name and do appreciate the advice. Will most likely save me time, money, and a headache lol.

[Dolsey056]

Now is the Cam going to be computer controlled and if not how will it effect it? thats the other thing I was curious about is if I have to stay with a computer controlled cam.

[steveo]

you can use any cam you want.

the more extreme the cam, the more difficult to tune.

those 'computer compatible' cams you see are a marketing thing. they are designed to be 'close enough' to a stock cam so someone doesnt necessarily HAVE to tune it to make it driveable.

since you're willing to tune, that doesnt matter

fast355 is right, that cam isn't right for your application

The cam in your engine is not computer controlled. I think your confusing that with maybe newer vehicles that are or looking at cams that say Computer Compatible?

Don't be fooled by computer compatible cams, they are either so small you may as well keep stock or you won't see any difference till tuned anyway! Fast will keep you dialed in with your motor build!

Yes keep the 63965, you have an E trans right? So the mask for that PCM is usually $0E, which is as good as 97427. Your ECM is basically same thing. Or do you have a manual trans and the other type ECM with similar number? Pull out your glove box and find out what's in there, it will have a four letter code, the BCC of the chip as well. Then you can start looking at it in TunerPro RT. Free to use but please pay the small registration fee of $39.

Yes tuning is hard. It takes a lot of reading, learning and practicing. If it's something you wan to do? You'll be rewarded for the rest of your life with a new time consuming hobby! If you don't have the desire or time? Don't start and just have a tuner fix you up with a chip for the motor build.

One thing you should have is a cable to hook up to your truck and laptop. The tuner would need data logs and this fits the bill. This is as good as and even better then a scantool. Which is a must have tool if you work on your own vehicle.

If memory serves me right 63965 either ran $E6( non-pwm 4L60E)or $OE (4L80E)and the 7427 ran $ OD(PWM 4L60E)and $31(4L80E). There was also a modified version of the code used in some later CPI 4.3 applications.

The two cams I mentioned are very TBI friemdly with some VE and timing tuning. Most will notice I do not run the latest and greatest flat tappet grinds from anyone. I feel the ultra modern ramps such as the Lunati Voodoo or Comp XFI are just too agressive and require too much spring pressure to have an adequate life on todays zinc depleted oils. The older grinds live longer on the streets in engines that have to idle for prolonged periods and still offer nice gains in power and efficiency if matched well to the rest of the engine and drivetrain. Not to mention valve lift much over .460 or .470" does not gain you much except a headache to setup the valvetrain on a TBI head. I like to keep the lift at around .450-.460 so that only a mild spring upgrade is required. The matching crane springs will allow the valvetrain to be free of valve float until above 6,500 rpm, way past the useable range of the swirl ports and dual plane intake.

Okay so download the Tunerpro program, Buy the ALDL cable, install cable and do some reading on the files? And yes its the 4L60E. and the cable I need to buy is the one at http://www.gearhead-efi.com/Fuel-Inj...uy-ALDL-Cables!. Now also with the cam grind am i correct by thinking the cam has to be ground down to fit in the 305 block? I was looking for a Crane 272 and it came up with results for a big block.

[Dolsey056]

Fast 355 do you have any suggestion on which Valve springs would work best on the Crane 272?

The ones crane suggests, I run them on the vortecs on my vette.

Alright So I had a 350 bored 20 dropped in with hyper flat top 4 brow pistons, and Edelbrock performer intake, roller tip rockers. I got the aldl cable and downloaded TunerPro but its not connecting to my truck. It keeps saying not ready. Not sure if I need to do something different or need something for Tuner Pro to work off. any advice would be helpful. Im going to reread the forum again but definitely could use some help. Oh and the cam they put in is just an RV cam till I figure this tuning stuff out more so its 280* 295* @ 420* 446* 204/214 duration

[Loyd]

follow the tutorial for tunerpro and you will need to download at least 2 files and maybe 3. these files depend on what computer you have. use tunerpro xl cause then you can log data for a custom tune.

birkenstockThe motor patterns are pretty well learned at this point. I've changed the way I move through the ball, and these shoes that I wear with the flexibility in the sole really help me. If I wear a really rigid shoe I can't turn as well on it.". They keep their heads up and they play as hard as they can. But I know it frustrating for them. The four varsity returnees and 10 JV players, Moore will have just 14 players in the program when the season ends. The Dunk is a relatively simple shoe with basic stitch www.birkenstocksandals-clearance.com/t17200-womens-gizeh-black-patent-sandals-p-37.html lines along the shoe. With the simplicity of plain leather sections on the shoe's upper, and a rubber midsole and outsole as the shoe's base, the Dunk has reemerged as a perfect candidate for a wide range of color arrangement and placement on the latest models. It is this wide assortment of style options that is available for the Dunk that has caused these shoe lovers (affectionately called "sneakerheads") to chase after limited www.birkenstocksandals-clearance.com/t3652-womens-sparta-chocolate-patent-sandals-p-7.html models issued by Nike, causing some serious collectors to bid hundreds of dollars for special edition Dunk over the Internet.. As for working out, can you take walks while you are on conference calls I don't know if you do conference calls, but if you can take an hour walk during an hour conference call, that could help. I would also set aside some family time for exercise. Bike around the neigborhood on nights your kids don't have activities. Tom was preceded in death by his parents and his brother, James C. Hobbs.
