    318-3, J heads, Hardened seats, and a few other ????'s

    Hello everyone. I have a few small block questions for you. First off, I am looking at a car that is supposed to have a 318-3 in it, is there anyway to verify just by looking at the engine? Second; Do 73 J heads have hardened seats and how do I tell if they do or don't? Third; Can I put...

    Edelbrock Heads and Fuel injection vs OEM Mopar magnum heads and EFI

    Hey all, I am looking at a few different things and want to get an idea of what way would be the better way to go. I want to turn the wagon into a nice driver that looks and drives great. I have really decided that fuel injection is the way to go, but have mixed emotions on the OEM Mopar...

    Well, I have kind of decided that I am probably going to regasket the 318, use the stock heads and cam. Maybe throw on one of the performer intakes. and drive it. What is the difference of the Weiand intake and a performer with an inch carb spacer? Then they will look about the same. I don't...

    will J heads work on a 318? And many many more questions.

    The port I am talking about isn't a water jacket. But if I can put the gasket up to it and mark it so that it is the same size, I should be fine. As for the intakes. I really like the look of the stealth and would prefer using it over the edelbrocks. I am using an 8 3/4, so it's not like it's...

    Also, is it bad to block off the EGR port? will it make any difference? I know some gasket sets come with a little plate to put over it.

    Here are a few pics of my intake. One other thing that is going to have to be taken care of with it is, I am going to have to grind a piece off just so that the valve covers fit. Right above the ports on the back pass side there is a little square block thing. It won't let the covers sit flat...

    Thanks Rumblefish. I have no real idea how to port the heads. Are you talking about the ports where the intake matches up as well as the exhaust? Also, what do I have to do to get the 1:88's to fit. Are the direct replacement? The engine is a direct take out that only has 70K orig miles on it...

    will J heads work on a 318? And many many more questions.

    I do have allot of parts to choose from. Four intakes (three are edelbrock performers though), J heads or 302 heads or the stock ones, 360 or 318, 904 or 727, Carter AVS or TQ or brand new in the box Edelbrock 1406. Edelbrock performer cam or Crower Beast, All of that stuff and I still don't...

    Man, I don't know that I have the patience to build an engine. lol. Funny thing John. I found one when I went and got the 69 Coronet up in Twin Falls. It looked pretty good for a field car. There is also a 64 Plymouth over in BE county. As much as I hate to say, I may just go Edelbrock...

    Thanks, I will. It will be a few weeks before I will get to do much on it. I did get the engine mounted on the stand today. But thats all I got to do. There is also a few more things I need to get before I can assemble it. Hoping by Christmas though.

    John, not sure what I am going to do yet. I am still trying to decide what heads to use. :) I want it to be a good streetable engine that can perform. As for the keys. I think the set that I have was Mopar Performance. But I don't remember. As for the springs. We have already decided that they...

    The intake I have is #7507 and I can't find info on it. I will send Crower an email when I get the casting numbers off of the heads. Thanks again all. Another thing. I know you can buy keys for the cam to adjust the timing. Good or bad idea?

    That is the exact cam I have. Do they answer those questions?

    So the Crower will work with the twirl port heads?

    I have never used a stealth and I got it in trade. I know it is about an inch taller than the Eddy. I like the look of it more to. But I really just want a good reliable fun car that runs on pump gas and has a little bit more umph. Thanks so far for the suggestions.

    I have two intakes to choose from. A weiand Stealth and an edelbrock performer. I would buy a different cam, but I am trying to use what I already have.

    I have a set of the 1990 318 twirl port heads.Are they the later 318 heads you are talking about? I have the whole engine. It was a throttle body injected with the roller lifters. Would those be better than the J heads?

    Would I be better off with a Edelbrock performer cam?

    Not sure of the ratio now, but the cam specks are 269/282 adv 480/494 gross. That is what I was told from the person I got it from.

    I am not building this one to be a race car. I am however using a crower beast cam and I am debating on weather to use the Weiand Stealth or Edelbrock performer intake. I will be running duel 2.5 exhaust with an H pipe and a 904 with 3:23 gears. I am hoping for a dependable driver that I can...

    So, if I choose not to mill the heads, would it be better to keep the factory heads? My engine is a 1969 318 with 70K orig miles.

    J heads were on 71-72 360's and 71-73 340's.

    Well, since no one seems to want my J-heads, I am thinking about using them on my 318. Are there any mods that I would have to do so that they will work? Thanks. Jeremy

    Good trade???

    John, you know where there is a pile of 440's if you ever want one. :) I have one or two myself.
