    5.7 Vortec and TBI

    Scoggin-dickey made a tbi intake for the vortec heads back in the day. That would be slick. Also it is very easy to make the TBI adapter plate.

    Which dually - 8.1 vs pre-DEF 6.6?

    Yeah the 6.0 is what it is. Another thing to consider is the availability of an 8.1 truck. I'm pretty well immersed in the biz, I've only seen a handful of them in the wild and that was yrs ago. Up here in the rust belt those years are all but gone too.

    Which dually - 8.1 vs pre-DEF 6.6?

    Clean, stock diesel trucks are out there, you just have to know where to look. Stay away from the diesel forums, those are all beat like rented ******. The key is to buy them before the tuners get their hands on them. I'd also venture to say most LB7/LLY/LBZ trucks at this point has had new...

    Square body on new chassis?

    The hydroboost is from the 05. I drilled new holes to mount it. The 77 had a normal booster. That was no big deal at all. The steering shaft was a little more involved. I bought a universal joint from the local speed shop and had to weld the 77 upper shaft to the joint. The 77 double D shaft...

    5.7 back fires through carb but timing is good.

    I would check for a flat cam. Turn it over with the valve covers off and have a look.

    The duramax will have better resale value. Folks are all over the older diesels. The 8.1s are beasts, but will always use way more fuel getting the same job done.

    OEM cylinder head castings - 1977 K10

    Not for nothing there are way better stock appearing heads out there. I can appreciate the stock build as well though. I have bone stock numbers matching cars and resto-mods.. stock appearing builds with extra HP are my favorites..

    Summit Brand Headers???

    Anything that is summit branded is usually bottom of the barrel for quality. Few things in this hobby are worse than cheap ass headers!

    1984 Square body

    The duramax and allison made the swap much harder I think. The motor and trans are both huge, plus the intercooler and giant radiator. I have a thread here from awhile back. I'll post the link if i can find it.

    Your best bang for the buck will be the right torque converter and some gears.

    Update on my Ignition Module failure!

    People think I'm nuts for this but a solid source for real GM parts is the boneyard. I have pulled modules from parts cars and gotten a long life from them.

    Update on my Ignition Module failure!

    Put a points distributor in it. That will run forever. You'll need to adjust them once in awhile though.
