    how to hard block a 400 B engine ?

    Interesting idea. How many spots per freeze plug, and any particular positioning (12-3-6-9 o'clock?)

    how to hard block a 400 B engine ?

    Follow the company's instruction for the mixing of the hard block. An engine stand that will allow you to position the deck flat so you can do one side, and then the other will go a long way. Pour it in via funnel and use a dead blow hammer on the side of the block to help work out air bubbles...

    Magnum head porting, worth the cost and effort without cam swap?

    Long story made short. My 97 Ram 5.2 started knocking, main bearings. After we pulled it out, and started disassembly, I find one of the cam lobes is starting to be bad. Either the cam has some casting issues, or it has worn through whatever surface hardening treatment. Roller lifter is fine...

    turbo stuff

    It sounds like a "draw through" versus a "blow through". First and foremost, any forced induction system will need fuel system modifications to keep up with the additional fuel flow needed for forced induction. Not enough fuel = LEAN and lean under boost melts pistons. Draw through is not...

    turbo 360

    AnotherA has the basics very well covered. The basics are are the flipped exhaust manifolds or headers to route the exhaust to the turbo, the downpipe(s) to route the exhaust after the turbo, and the charge piping from the "cold" side of the turbo, into the inlet of the engine, whether through...

    Big smallblock power..Turbo?

    The fule system definately is the cost killer on many turbo systems. There are lower cost options, in using the non braided hose that is offered by Aeroquip and others. Fittings are expensive

    Big smallblock power..Turbo?

    MShred. I think you are wrong here. Momoparman commented on your original post, where you were talking about a naturally aspriated build, and turbo build, in the same sentence. He went off on a tangent about a stock 340, which is apparently not of interest to you. Had you politely declined...

    Another 75hp please

    Choose your words wisely, as the wrong words come accross arrogant and condesending. My input, based on your descriptions, is a head and cam package, and possible intake depending on what the older crate engines came equipped with. I would also look at carb, 625 is adequate, and better for...

    Something different Building for MPG.

    I would not think a Dart Sport / Duster / Demon would be too bad, with the swept line portion of the rear roof. The Swinger / Valiant / Scamp would be a little worse IMO since they are a little more boxy, and less smooth coming off the rear glass and trunk area. Granted, the nose are is pretty...

    Something different Building for MPG.

    I do not have specific numbers right off hand, but the amount of the alky injected is minimal, but since it atomized, it kills 2 birds, so to speak. It takes heat out of the intake charge, and it is flamable, so it burns in the cylinders. The info I read is the the reduction in the basic...

    318 build. what would you do?

    The guy wants to maximize the 318. Let's help him do just that. The point of the post is to get suggestions on how to build the 318 for what he wants to do. While a bigger engine might accomplish his goal EASIER, it is not the direction he wants to go. Once he has made it clear that...

    Something different Building for MPG.

    My /6 build: Stock slant 6. The 7.5 compression is begging for a turbo. An appropriately sized turbo, blow through on a small 2 bbl Holley carb. A well designed exhaust with minimal restriction, built for velocity, with a straight through muffler design. I would run some version of a 4 bbl...

    Something different Building for MPG.

    Don't rule out turbocharging in any of the projects. The hidden benefit to turbos, beyond the force feed power when WOT, is the heat. Most run some type of cooler, to bring temperatures down to reasonable levels. It frequently does not get it below ambient. The additional heat better...
