    What torque convertor do I use?

    correct. "LA360" is external balance. just know that chrysler had more than one "external balance sb's" so "LA360" is important. if you converter has a weight welded to it...it's not balanced for a 360, since it was behind a 340 originally. If it has no weight, it may be internal...

    What torque convertor do I use?

    BluePrint Engines 408's are all "LA360" balanced on the REAR. do not confuse that with the fact that we use the Magnum balance damper on the front. As @Professor Fate mentioned, 340's are unique in balance. it'll depend on if your previous 340 was stock balance, or had been rebuilt to...

    Plug and play distributor

    We work direct with the factory, and ours come down the same line as other famous brands, and go in BluePrint boxes. I have been to the factory, and actually helped setup the end of line testing, including vac advance operation, tach signal function And clarify, mechanical advance and curve...

    MSD or Blue Streak wires?

    Just a heads up, you posted both male and female terminal wires. Make sure you order the correct ones for your distributor. Personally I like to assemble my own to avoid the spaghetti and run them the length I like. Moroso makes ours. 8mm Spark Plug Wire Set - 180° Boots - Chrysler and...

    Flexplate and TC for a BluePrint 408 Magnum

    Personally I like Yank torque converters out of Akron ohio. They are owned by gearstar transmissions. They are 100% custom, and will build one specific to the car. High-Performance Transmissions, Custom-Built - Gearstar Yank Custom Built Racing & Performance Torque Converters If you are...

    Flexplate and TC for a BluePrint 408 Magnum

    Morning all, Let me try and clear up any confusion on the matter. Even though our engine uses a Mangum block, it's built to be as close to an LA engine as possible. The only thing "magnum" about it, is the block, the weight on the harmonic balancer, and the intake bolt pattern. The REAR...

    I'm thinking I put too small a cam in my 360 Magnum...

    I wish you luck my friend. I can't say I would purposefully build a nitrous combo with stock cast pistons. And if they weren't specifically gapped for nitrous, you could easily butt the rings and pop the top right off of them with 200. Be really careful with your timing, and read plugs every hit

    I'm thinking I put too small a cam in my 360 Magnum...

    There's alot going on here.... stock cast pistons, what ring gap? Assuming no anti balloon plate on the converter? Going to put 1000 cfm worth of carbs on a stock 360 cid engine? And ya, asking alot of a 7 inch slick if you're going to just hit it off the line.

    TF & Speedmaster Flow Tests

    I stopped getting excited about the TF heads about the same time you did. When the rumors started swirling of an OOTB 300 CFM head, knowing what it takes to get a set of Edelbrocks or there, it seemed too good to be true. The first few 408 builds i saw using them making "ok" ish HP, and then...

    TF & Speedmaster Flow Tests

    at one point i had an old M1 that i almost ran, but couldn't convince the spread bore flange (or modifying it for a 4150) was the right thing to do. Is there much out there thats supposed to be better than a Super victor?

    TF & Speedmaster Flow Tests

    Thats where it was done making HP, so thats where i shift it. haha. it will lose some if i short shift it. I used to have a cheetah that i absolutely hated, and would shift early by mistake. Went back to a B&M pro ratchet and never looked back. It probably weights in a tick over 3100 with...

    TF & Speedmaster Flow Tests

    it runs 10.20's with a full interior, 3.91 gear, in a 10x 26 inch tire car. I shift at 7400 ish. traps 126-128. our track is notoriously "slow" as the last 1/8 mile is uphill. it's been a great engine. I have dyno sheets with 618HP @7400. before i switched to E85. Heads flowed a best...

    sick week 2024 pictures.

    Thanks for posting. These are really cool. Does that late model durango with the blower actually run? If so what's it do? I saw it (or one identical) in the mopar booth at sema but it didn't even have a driveshaft or electronics. Just an engine sitting in a chassis. Or maybe they finished it. Thx

    the crazy thing is how tame both the 610 HP N/A, and the 872 S/C are....they make like 19 inches of vacuum... We turned one of the S/C up in R&D and almost hit 1000, but were out of injector! "Bigger" versions to come! I'd like a Nastier cam N/A that surpasses 700, and then of course a...
