    Vortech, 502 mag 525hp manifolds

    I can't remember which thread it was in but someone mentioned the marine vortech manifolds which reminded me that I have some things laying around. Pardon the dust in the pics, lol

    Ummmm, let me try to post the pics again.

    As you can tell by the dust the price could be right. Let me know if anyone is interested, shoulda ebay'd this stuff forever ago. I'll blow stuff off and take better pics if anyone wants something.

    I think I have 4 525hp BBC intakes, 1 502 mag intake(All rectangular port), 2 scorpion SBC vortec intakes and 2 regular SBC vortec intakes. All of these are marine intakes meaning the water thermostat crossover has the brass inlay. I would have to check the SBC intakes to make sure they are cast iron and not plastic, pretty sure iron or aluminum but didn't look.

    I was thinking that too but looking at the pictures the TB would be facing the brake booster in a car/truck application.

    IF the plenum is designed the same way as the Indmar intake I have, it will bolt on either direction or very easily be modified to.

    Sorry for the delay, I've been laid up in bed the last couple days. I'll get some better pics next time I am at the shop.

    I would be interested in one (or more) of the 525 MAG BBC intakes if the price is right .

    Are these complete with TB and fuel rails / injectors ?

    P/M on here or email tomsnastyz@yahoo.com with pics and price .

    Thanks

    Ah Heck, here I am at the shop at 2:15 in the morn, gotta get a bit of work done. Here's some pics of the scorpion. Turning the top around is possible but will take a bit of work. The factory setup used a 2 wire ford type IAC so that would have to be blocked off to turn it around. Also, once turned around you would need to drill and tap the base as some of the bolt holes won't line up. Not that big a deal but would have to be addressed. Also the 90mm TB doesn't have an IAC provision so you would have to run an external IAC adapter. Next time I am over there I will take a pic of one and post. Basically a hose will go to the adapter which is billet aluminum and a stock gm IAC bolts to it.

    I hate bog the forum down with too much bandwidth on pictures so please PM with email address and I will try to get any more info and pics to anyone that way. As for the TB pics, I really need to remove them and measure with a dial caliper and I will another time.

    I also found this which is pretty cool. It's a vortec dual plane intake with a 90mm TB. :) It is cast iron.

    Btw, anything I sell, I will clean and flow test the injectors, this stuff has been around a few years. I will also run everything down to the machine shop and run through the parts washer for a few minutes to clean up so they look new.
