OK I have been shown the light, I can run a 7427 for a 4L80e and convert it for MPFI.

And I can find 16197427s everywhere reasonable BUT no one can tell me anything about the van or truck they came out of.

They cannot tell me what transmission, engine of even if it was even running when hit.

My old friend who had a junk yard would often say when asked if a part was any good, “Well it was moving when it hit something.” He could then show you to car or truck it came out of. Sadly he passed 7 years ago and wife sold yard.

So looks like I will need to load the basic operating system for a 350V8, for a 4L80e and hopefully for lean Burn Cruse.

My read is I can get any 7427 and just reprogram it…Correct??

Can someone tell me how to do this and what tools will be needed??

And are all operating programs on the EPROM or do we need to make changes to the main ECM??

Best of all worlds will be to have a person load these programs to an EPROM or chip as I also have a Moates Memory Adapter With a preloaded MPG custom chip.

Plus the older EPROM chips from my 93 350 4L60e 165 ECM, so how much of engine and transmission programs are in the EPROMs?

Can I just plug them into a 16197427 and just take off??

As this will be a fresh start up of a new engine I hope to have a good ECM to light it up.

Perhaps someone can sell one? A 427 ECM or loaded EPROM or suggest a good tuner/programmer?

I have a 427 with a 305 tbi memcal I’d sell

 

"I have a 427 with a 305 tbi memcal I’d sell"

And chance my 350 Memcal will work in it??

And any chance it is set up for a 4L80e (unlikely with a 305)

Can you program it for a 4L80e?

PS How interchangeable are the Memcals from a 165 to a 625or 427??

An is the enough different between a 625 to a 427 to be worth the trouble?? I keep reading a 625 cannot run a 4L80e.

What is the 350 memcal from a 427 ? Did you see the link post 6 on your other thread how to modify to mpfi ?

 

16196395 or
16197427 usage 94 - 95 C/K Truck, Van, S-10 LN2 (16168505), 4.3L, 5.7L & 7.4L

 

"What is the 350 memcal from a 427 ?"

You offered a 427 from a 305, I am asking what it will take to up grade to a 350/383??



"Did you see the link post 6 on your other thread how to modify to mpfi ?"

Yes and downloaded all the files.

The main problem is getting a 427 to run a 4L80e.

A 305 tbi 427 memcal will work for 350 or 383 but knock filter isn’t ideal for 350. As long as a conservative timing table is used it will work. Programming fir a start tune is described in the write up. Datalog and refine fueling.

 

What will it take to get it or one already set up for a 4L80e and a 350 with a good knock filter ??

Rich

 

if your wanting a 350 memcal search eBay then solder in a moates d2 and push in a sst 27sf512 eeprom or use there g1 adapter and piggyback as well as cylinder select. All h the peramiters to get started are later out at gear head efi.

 

Thanks.
