[DeTomaso] Stack injection units

Thanks to all who replied. I am having a new engine built. Right now it
looks like I am going for a stock displacement with a forged internals,
around 10.5:1 compression ration a custom cam grind (worked out by Dan
Jones ) and C302 B heads and 180 degree headers. If i decide to go with a
stroker I would have to choose different heads. I like the the fuel rails
that run" inside" between the stacks , but that is not the most important
issue to me (looks). When I asked for a consensus for "best" I should have
defined what I meant by "best". My best is reliable, ease of tune, best
horsepower ease of upgrading to higher capacity injectors in the event of
a cam change or other change that would require higher lb injectors.
Personally I like the set ups that use modified Weber's vs Plastic
throttle bodies, but I don't know much about them except they are expensive
and are supposed to improve fuel economy and will stay in tune with
atmospheric pressure changes. Ideally I would like a system that gives
performance comparable to Weber's but without the tuning difficulties there
are infamous for.
I would also like a setup that isn't more expensive then it needs to be.
Thank you.

I like the TWM throttle bodies. I have them on my Pantera and my GT40.
The Pantera has older style throttle bodies which were supplied in the
mid-90's by Quella with an old F9 Haltech EFI system.

The fuel rails are on the outside, as you can see.
I honestly don't know if Quella still does the EFI systems. Last time I
talked to him he sorta' indicated he no longer does.
You'd have to check.
When the ancient F9 in the Pantera let all the smoke out, I replaced it
with an Electromotive TEC GT.
The GT40 has an Electromotive TEC3r.

pg.jpg
The fuel rails are on the inside with this setup and it looks
'cleaner', I think.
I like both TEC units. They work.
The TEC3r is more expensive, but has more control and inputs/outputs
and can do fully sequential injection on a V8.
The TEC GT can only do what I call 'batch fire' on a V8.
That old saying... you get what you pay for.
Lots of people like the FAST system. I have no experience with it.
Steve Hawkins uses the Accel system and seems to like it.
FWIW,
Kirby
