Does anyone know where i could pick up a ecm Prom for a 87 l98?

 

Ebay, Junkyard, and here http://tpiparts.net/82_92_ecm_and_prom

 

See if the Dealer has a stock 350 prom about $40.00.

 

A reasonable price from a dealer??

 

better to spend your money on a custom chip and piggy back it with your 305Prom,
assuming you swapped the 350 in and not the 5 speed,

plus then you can get a chip made for a stick 350 and pick up some power while your at it,

a 350 will run fine on a 305 prom

 

Have a complete 91 L98 ECM that I will sell you for $50.00.

 

well i wasn't really lookin for a chip for my 88 but i guess since you said i could get some more power out of it since it is a 5-spd, and it does have a 350 chip, the tranny was put in not the motor. where would be a could cheap place to get a chip for it?? and then could i just put my 88 l98 chip in my 87???

but i was really lookin for a chip for my 87 which is im hopeing is a 350 instead of the stock 305, chech out my other thread "is it a 305 or 350". i wanted a 350 chip for it cuase it if is a 350, then it has a 305 chip in it and i wan't to get the right chip, but i guess u said a 350 runs fine on a 305 chip and my 87 runs awesome but it doesn't quite have the ***** as my 88

 

i dont think i 91 chip would work on a 87 but thanks anyways! and i dont think im smart enough to convert my car to speed density, to many wires to deal with

 

my bro was running his 350 with a 305 prom fine,

but it would run better with a 350 prom,

if anything go buy a hypertech for an 89 350,
but if you got the stock 19# 305 injectors or its a 305 the car will run lean which is not good

 

like it said, could i just take the chip out of my 88 l98 quick and but it in my other one to see if it made any difference, or if it did would i even notice it?

 

There should not be any wires to deal with as far as I can recall. Since there is no meter to deal with, the caf should just start and ren base off of the calculated values.
