    lowering a 383 into A-body

    Honestly, I'd just take the time to figure out a dolley system and use the engine hoist to raise the front of the car. It seems so much easier to put the motor in from underneath. That's what I plan on doing in the next month or so.

    lowering a 383 into A-body

    I think he's trying to say that having the rear end of the car up on ramps/stands will make it easier because the engine/transmission will not need to be on a steep entry angle in order to get into the engine bay. Then, once it's in the bay, the rear end can be lowered and the engine/tranny will...

    Leaky 400 RB... Any suggestions???

    Thank you for your response moper. I am going to pull the manifold tonight. I think the overheating might have caused the seal in the studs to burn up, or perhaps dissolve, as the area right beneath the rear stud is the main cultprit, but I don't know what is causing the leak near the "shared"...

    Leaky 400 RB... Any suggestions???

    I was told that the Copper RTV worked best on those. I'm going to order some valve cover gaskets along with new exhaust manifold gaskets. I plan to retorque the heads, reseal the valve covers, and reseal the studs going into the water jackets. If that doesnt fix it, time to pull the motor. I...

    I doubt I warped the block, but I do worry about the heads... I have not tried to retorque the cylinder head bolts, but I probably should pull the valve cover along with the manifold. I did try tightening the exhaust manifold bolts and they did tighten up a little bit, indicating that they were...

    Leaky 400 RB... Any suggestions???

    Disclaimer- This is not an A-body, but it's a big block Mopar (72 Roadrunner with a 400/727.... close enough? Hope so. It's really bumming me out. I guess I'll start this one from the beginning. I was driving my Roadrunner one night around 10:00pm and came to a light on the highway next to my...

    400's are they any good?

    I love the 400 that I have in my '72 roadrunner. It's built to mostly stock specs, except for hyper-eutectic pistons, a performer intake, and a slightly bigger cam. It pulls hard all day. If I put headers and a better carb on her, she'd be a screamer. I say definitely go for it.
