GM TPI tips for a newbie

[Peter Fenske]

Hi Charles

For the money the stock setup is ok. You peak rpm is gonna be
about 4500 rpm but the torgue is awesome.

Buy SVO injectors from ford. The 24# would do the job and run bout 200$ a
set.

As for calibrating your chip there is a lot of helpful people round here.

With the 406 you are facing the same lemma as me.
My vette runs a traction limited 13.2 at about 107 with the stock
manifold. The way to get bout a half second is to go with the tpis
miniram..But they cost in gold.. Bigger runners, the superram are
just a crutch when you deal with 383s and 406s..

Hi all, I joined the list to gain more info on EFI operations
and maybe a little knowledge, If I don't get lost too quickly!

I have a 1987 Monte Carlo SS as a pet project. I recently
installed a built 406 and I've been contemplating an EFI swap.
Well, I stumbled onto a TPI setup from a 1985 5.0 Camaro and
contemplation time seems to be over :)

The 406 flows A WHOLE LOT MORE AIR than the 5.0 so I know I
need to use larger injectors. My guess was 28-32 Lb units but
I'm not sure. I've spoken with a few places about a custom
chip for the ECM but everyone seems to carry "Off the Shelf"
chips instead of doing any custom work. I'm unsure of my
options at this point.
