Ok, sorry about that

I’ve got a couple of marine intakes, I’d take $50 plus shipping.

The street Dominator is basically a 273 HiPo manifold cast in aluminum, they had a small plenum and small runners to keep Port velocity high. The street master on the other hand has a choked down tiny plenum and runners and runs out of pull around 4000 rpm. I wouldn’t use one of them for...

I’m in Louisville Ky but I drive through Georgia all the time on my way to Florida.

Yeah, the Holley Street Dominators for small block is essentially a 273 HiPo intake in aluminum but with the bigger carb base. And the best part is they can be had relatively cheap. The Marine manifold is the same thing except cast iron. They made 2 versions of the Street Dominator and both...

I’ve got several 318 marine intakes if you need one.

Brand new heads, never had any work done to them.

OK, the motor is a 1993 5.9 magnum block bored .030 with a 4” Scat forged crank, Eagle I beam rods and forged Pistons with a 17cc dish. The blocks not decked so I don’t know how far they will be in the hole yet. I will include a photo of the cam card. I have a couple laying around but the one I...

i picked up a set of EQ heads with valves and I’m getting ready to assemble them for my 408 Magnum. The cam I have will have right around 550 lift with 1.7 roller rockers I have. Who makes a good valve spring and retainer for this application.

That's OK, I eventually figured out the 2 sets I had. They made so many variations of those heads and very little published info.

Sorry, wrong picture, I've got 2 sets of those for sale also

They are $1085 from Jegs and Summit, I'm asking $700 but I may split shipping with you. I don't know who makes them for Mopar

If you decide to stroke it I have several Mopar Performance forged 4 inch cranks I will sell cheaper than you can buy an Eagle or Scat for.

With the forged flat tops in my 408 I checked with a feeler gauge and they were .022 down in the hole. What I thought was going to be a lot of compression turned out to not be as bad as I thought.. you really need to take the heads off and get some good measurements before you decide what to do.

The J heads have big ole chambers, probably 70+ cc's

Check your compression ratio with a calculator, unless you have some type of dish piston with the 4 inch crank your static compression could be pretty high. My 408 with flat tops and valve notches and a zero deck put me up around 11.75 with the 60779's

I'm sure there are better cams made today which could be the topic of a really long discussion. What I'm trying to do is use up all this stuff around my garage. I'm sure if I spent a couple of thousand dollars on different parts it might make more HP or go a little faster but at the end of the...

I've used Racer Brown, still have one for a big block. Iskys are good too.

I've been using Direct Connection/ Mopar Performance cams for at least 40 years, never had a complaint. I've got a couple of Crane Zip 518 solids I've had for 35 years, can't complain about those either

Actually I will be building with each cam, just figuring out the immediate one that's on the stand now. I've pretty much decided the solid MP cam is the best one for this motor. The other one will end up in this Magnum based 408 stroker with EQ heads, I can run it with the Harland Sharp 1.6...

Yeah, it' amazing what I can dig up in this place. I'm determined to build 4 or 5 small blocks with everything that's laying here, I don't know what I'll do with them. I just bought an old 4 door 70 Valiant to use as a test mule. Just tired of having this stuff laying around. Incredible what...

I guess technically they are both about the same lift since when you subtract your lash which is 28/32 you end up with 529/525 out of the 557 mopar cam. I'm leaning towards using the solid cam in this motor and saving the Comp Hydraulic for another Magnum based stroker I have, with the 1.6...

i have this 408 that I have been building out of junk I've been digging out of my garage, I've come down to choosing between this Comp cams Hydraulic, CRS 305H10 which is 525 lift 305 duration 110 centerline, duration @050 is 253. Or the Mopar Performance 557 lift solid cam which is 296 duration...

That cam will work fine in a stock 360 short block and will have a very small lope to it. Should be good and torquey. The intake and carb will work fine also. That cam is basically the same as a stock 340 4 speed cam in 68 except it has a little more lift.

Right, I'm going to order some of the .070 gaskets from Summit and use the Edelbrocks. Still have to dig through my cam pile and see what looks good.

I'm with you, I don't think on this motor it will make a bit of difference, I doubt I'll be changing the Pistons since it's assembled and balanced, as far as that goes I could run the .028 gaskets and the open chamber iron heads I have. I haven't worked up the compression on that combo yet.

OK so I checked my motor and all the Pistons are sticking out .027 so with a Cometic .070 gasket I would have .043 piston to head clearance. The next step down in off the shelf gaskets would be .060 which would give me .033 piston to head clearance. With the .070 gaskets I calculate 9.658 comp...

another interesting tidbit from the Mopar Engines manual, they say that the Offenhauser Port-O-Sonic is the best intake to run on a small block, they're not bad but I'm pretty sure a Holley Strip Dominator would make more power.

I don't have the Edelbrock open chambers, that would make things incredibly simple. That's page 55 in the Mopar engines manual 8th edition around 1991. I went back to my Direct Connection book from 1976 and it didn't even mention piston to head clearance. I just put that on here to show how...
