[Chevelle-list] aftermarket efi

[Dale]

I had an Accel/DFI port injection on a 67 Chevelle I used to own.
http://dalesplace.com/htm/chevelle/chevelle.htm then click the Engine link.
I loved it.  Started easily in all weather conditions, ran smooth, very
sharp throttle response in comparison with the Holley 4-bbl I had for a
number of years.  In the four years I had it installed I put probably 25K on
the car.  Drove it from Lawton, OK to KC numerous times, Nashville, TN a
couple of times and, weather permitting, to-from work every day.  I did have
one Accel external electric fuel pump go bad after about 3 years (it tended
to overheat after 7-8 of highway driving) but other than that, no tuning or
maintenance problems whatsoever.

 

Mileage did increase a little but not enough to warrant the installation
just for that reason.  Unit also required a late model computer-controlled
distributor but MSD solved that.  The DFI computer could also control
electric fans (that I never used) and included a rev-limiter that shut down
the injectors when the limit was reached.  It also necessitated a 4" rise
hood but I wanted to go that route anyway.

Is anybody out there in Chevelle-land running an aftermarket performance
efi?  If so, what are your results?

 

Performance?  Driveability?  Cold starts?  Tuneability?  Other comments?

 

I'm just in the research stage now.  I've got my car to where it is getting
near the magic 11.49 NHRA rollbar requirement, and as mine is a Camino, I'm
not gonna put bars out the back window.  The power is great, but it's best
at wide open throttle, otherwise it's a bit much to drive.  It'll cruise ok
above 2200 or so, but it's not truly happy until about 4500.  I'm looking
for crisp throttle response and hopefully an increase in fuel mileage.

 

I love the look of the old-style Hilborn injection setups that BDS is
converting to electronic, but not having known anybody who has run one, it's
hard to justify the kind of money I'm sure it would take to make that
happen.  I've also read articles on the FAST systems, but in checking their
website, they don't appear to sell packages, but components that I would
have to figure out how to put together.  Holley Pro-jection?  I knew a guy
who had one when the first came out about 20 years ago, but I'm sure they've
progressed far beyond that by now.  I think I'd prefer a dry manifold system
anyway, ie port injection.

 

Thanks,

 

Devin
