    Ease of Removing Lift Off Hood

    They’re not that bad, I typically set mine on a folding harbor freight stand around the garage. I glued foam blocks to the bottom for setting it on the roof (that’s a bitch by yourself). I have 2 cars with lift off hoods. I now hate working in cars that have hoods on hinges.. lol

    Real 6 pack hood?

    Looks like the real deal. I’ve seen them anywhere from 1200-2500 or more depending on condition. It doesn’t look all that bad to me.

    A12

    Depends how for you want to go. Like mentioned the air cleaner alone will cost pretty much your initial budget. I actually have a ton of real A12 parts on my car. Hood, air cleaner (coolest piece IMO), 4.10 Dana. My dad has enough parts to build a correct looking RB for it and has offered them...

    Engine paint

    The Eastwood paint is pretty nice. I shoot it with a gun.

    TUNING A SIX PACK

    I don’t have any track data with the modified six pack or the mechanical carbs for that matter. It feels quicker than when it made the 10.90 passes. Although I’m putting a 4 speed in the car so I’ll never really get a true good test. The guy who I stole the intake mods from had a 12:1 TF240...

    TUNING A SIX PACK

    sounds like it works pretty good. I’d consider modifying the stock intake If you go back. I worked the dividers down a bit on mine. I picked this mod up from a guy with a really good running six pack stroker. It seemed to strigten up some of the low speed manors and it flat screams at WOT. Then...

    TUNING A SIX PACK

    I could see it on the A/F gauge, it felt slightly smoother with the higher number PV as well when you accelerate from a roll. Keep in mind if your vacuum outboards start to open you will see a lean spike untill the boosters turn on. No way around it.

    TUNING A SIX PACK

    the power valve has absolutely no effect on the idle whether it’s closed or open. The reason for the high number is the engine pulls extremely good vacuum once it’s going down the road. I have the jetting as such that it cruises high 13’s to low 14’s depending on the speed. Exactly where I want...

    TUNING A SIX PACK

    PV is part of the main circuit and provides enrichment during acceleration. It will not affect idle unless it’s blown or the gasket is leaking. For reference I run a 10.5 PV in the above pictured six pack with a .630 lift cam that idles at 5.5” of vacuum.

    TUNING A SIX PACK

    yes they are the mechanicals. I see no reason why it wouldn’t work. We did it to my buddies pump gas 440 six pack and it seems to like it. Runs mid 11’s @ 119 in a 67 b body street car.

    TUNING A SIX PACK

    They’re opened up a bit. The heads are Indy SR’s that are in between standard and MW port. I may open the intake up a bit more, my hesitancy is I could still use it on a standard port head at the moment.

    TUNING A SIX PACK

    They are down about 3/4 of an inch in the very middle. It’s one of those mods your almost afraid to do cause you hate to trash a six pack manifold. Glad I did though! Lol

    TUNING A SIX PACK

    when you come across a full weight 70 superbee at the track running 10.40’s with a 505 six pack you ask questions. Luckily he was nice enough to tell me a few things. :popcorn2: it may not look like it but they are scalloped down a bit to allow cross over.

    TUNING A SIX PACK

    After a very long hiatus with running dominators and single planes on my 511 I’m back to the six pack. I’ve spent some more time porting on the intake. The mods seemed to make the big motor much happier. I spent a few days re-tweaking the carbs going after every ounce of drivability with an 02...

    A12 hood part number?

    Best way is to compare what the underside looks like to an origional hood pic.

    TUNING A SIX PACK

    promax metering block is not a magical fix. It’s a BLP block that he has his name engraved into. The emulsion does nothing for the idle. It’s all in the IFR which can be easily changed in that block as well as the idle bleeds which are non adjustable unless you drill and tap them for set screws...

    TUNING A SIX PACK

    What I’ve found on my car is the my six pack 511 is it does the same. The intake distribution sucks on the bigger engine at low speed. Seems ok at WOT. I had to fatten up the outboard idle slightly to help it out. Unfortunately that also fattens up the cruise. So I kind of found a balance but it...

    TUNING A SIX PACK

    not sure why anyone spends money on toth heads. Buy trickflow 240’s. I ran a similar combo in my roadrunner. Flat top 440, kB pistons, stock rods, ported Indy SR’s, MP .557 cam with 1.6 rockers, 4.10 gear, 9 1/2 in convertor. Race weigh of around 4000#. Went a best of 11.58 with a six pack. Ran...

    TUNING A SIX PACK

    carbs have to come fully apart. You soak the hard parts in carb cleaner. Depending how bad they are depends on how long you have to soak. Longer parts are in there the more likely it’ll strip the coloring as well. It it was a running car you should be able to pull them down and get everything...

    TUNING A SIX PACK

    180 stat works just fine. That’s just someone’s interpretation of how they think tuning a six pack works. It’s kinda like the Internet, just because it says it doesn’t make it accurate :screwy:
