I am just about ready to start the fuel injection PITA on my sb400 and I
found this nice little setup and was wondering what you thought of it.
I am not building a powerhouse. I am pretty much retiring my 4.3 cause it
just doesn't have the towing power I need these days. I had talked to you a
while back about the edelbrock multiport injection system but I really don't
want to spend the 2 grand on it. Parts america has this holley setup for
around 800 bucks.
I don't think it's gunna feed her as much as she's gunna need bud. You'd
have to be really trying to get that 400 CID to put out 275 horsies or less.
If it were me I'd go with the 900 cfm, 4-barrel Holley Commander (P/N
950-21) which is rated for 350-500 horsepower.
That is something I need to check into still. The block has been punched
out .30 and I have a set of 9.6-1 pistons in her. Do you know off the top
of your head how many horsies a stocker 400 would normally put out?
With a mild cam that combo will produce about 330 horse and over
400 ft. lbs. of torque below 4,000 rpm.
I'd rather be blown than injected, fuel injection is great for efficiency
and emissions but a good carb/manifold combo can't be beat

This motor came out of my old 79 chevy truck back in 96. I mainly pulled it
cause it was getting tired. I really want to inject it cause the 8 mpg I
was getting was starting to hurt. I would much rather have it blown too but
when I am driving around a hundred miles round trip a day it gets expensive.
I had one of those Holley fuel injection setups right after they came out. I
know they have been redesigned several times, (
different somputer and software ), but they still have one major flaw! It does
NOT have a closed loop cycle to let you get home
after it quits working. Second problem is trying to trouble shoot them. It does
not have a way to store codes, let alone read them.
Third problem is replacement parts. I waited 6 months for a replacement injector
just so I could sell the POS. If you really want
injection, get a harness for a GM TBI setup. I got mine from Street &
Performance in Mena, Arkansas. ( www.hotrodlane.cc ). There
are several others out there that make harnesses also. Check with Holley before
you lay out the cash. My 2 cents worth of
