Doc,
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 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.Doc
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?
IIRC, my '74 sb400 2bbl was rated at 265HP. H
With a set of decent heads and a mild cam, probably 350 HP+. It will surely exceed the 275HP the system you're looking at is rated for.
Doc
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 beatsidewinder
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. (
