Will I run into any problems using the long block from a 1991 L98 (Camaro) and using my 1989 intake?

 

no

but what are you talking about

specifically

 

marcus88 is thinking of buying my 91 L98 350 TPI longblock and installing it in his 89 Camaro that has a LB9 305 TPI in it.

We know about the knock sensor, Memcal, injectors etc. need to be changed to upgrade to the 350.

The basic question is:

Due to the slight difference in stock 88-89 TPI cams compared to the stock 90-92 TPI cams, will the 89 350 ECM/Memcal work without having it programmed?

 

Cam specs if this helps

Thats not what we are asking

but thanks for the referrence.

 

you need to have the memcal programed

 

If he uses the 89 305 TPI memcal or

If he uses a 89 350 TPI memcal?


I know the 90-92 Speed density Memcals are picky about changes but I thought the 85-89 MAF Memcals were not as picky about changes especially such a slight difference in cams like mentioned above.

 

the 305 maf memcal is a little diff than the 350 maf memcal

I could be wrong

vader and sofa have been known to rain on my ignorance

I am far from right all the time

human you may call it

 

Sounds like your knowledge about this issue is the same as mine.

We need an expert to chim in.

All 305 memcals are different than 350 memcals.

 

The difference in camshafts is so small it will not make a difference to the computer.
