    Just for alittle personal info, could someone give me the specs on a factory 400cid sbc for a 1976 K5. ??? Compression, HP, Torque, ...ect. 400 4bbl. , I haven't yanked the pan yet, but I'm assuming it's a 2 bolt main. What's the possability it could be a 4 bolt main ??? If it is a 2 bolt, do you think this would be a good idea ??

    I think that would be an unnecessary expense. A 2 bolt block is strong enough up to about 500 hp...

    4 bolt mains are nice if you have them, if not it's not that big a deal.

    Yes if it is a 2 bolt main, splayed main caps are awesome. They are supposed to hold more power then a standard 4 bolt main setup. Definitly worth the extra cash if you plan to put some decent power into your 400. I personally want to go with a splayed main setup on my next motor (383 or 406).

    I've always built my motors to be able to handle alot more then I'll beat on them. I do plan on steel rods, and a steel crankshaft. Those caps are only $209.99 , so thats not to bad. Anyone know the factory HP, and torque rateings on the 76 400cid 4bbl in the K5 ??

    Plus an additional $200 to machine the block to accept them and align-hone after they are installed. I agree with Rene; a most unecessary expense. You can put together a rotating assembly for what those caps will cost you. Drop the dime on a forged crank and some rods.

    Paul,
    According to Chilton's manual a 76 400 with a 4 barrel
    175hp@3600 RPM
    290ft.lbs@2800 RPM
    4.125 bore X 3.750 Stroke
    8.25:1 compression
    min oil pressure @ 2000RPM 40psi
    does that answer everything?

    [/ QUOTE ] Lets try to keep the sh*t talking in OT. It's fun and all, but this is a tech forum. If y'all like edelbrock that's your choice, I don't, and that's my choice. So lets try to keep the it real in this forum please.
