Thanks for the heads up on the street dominator. I've never used one of the small block mopar ones but thought it looked like a reasonably good design compared to most of the other cavernous single plane designs. I've heard the action plus is good for milder builds but tends to have some mixture distribution problems from lower vacuum levels caused by long duration, large overlap cams, but it can be tuned out by staggering the jets.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 worked very well.
Hey that’s great to know. I am in process of working a 1985 360 four truck intake to replace factory single plane two barrel iron intake. From what I have read, the factory iron intake is actually better than an edelbrock performer 318/360 manifold... the only thing I don’t like about them is they aren’t made of aluminum, most boat anchors are light in comparison!I think a factory cast spreadbore intake is supposed to be a great intake on a 318. I would use that over a torker (tm-5) any day of the week.
I believe 318willrun did a test recently with the stock cast iron intake and a Weiand intake and the results were almost identical IIRC. Maybe someone can link it so it can be seen again.
Factory cast work great on all the small blocks. I've used them on 340's and 360's as well.I think a factory cast spreadbore intake is supposed to be a great intake on a 318. I would use that over a torker (tm-5) any day of the week.

I wish I could could find a streetmaster for free! Steve Dulcich of HRM claims that these are great manifolds for stock or mild street/towing type builds, with a strong off idle to 4,500 rpm power band. It would be great combination with a set of 302 swirl port heads and an off idle to 4800 rpm cam.Stainless steel allen key pipe plugs work great too. I use liquid teflon sealant on the threads.
I have access to an eddy streetmaster 318 from a buddy for free. Looks like a mini torker ll. Is this thing a low RPM torque killer? And if so, what could i use with it to get some of that back?
The plan is a mild build 1974 318 with 68 340 exhaust manifolds, maybe a set of 302 or swirl port heads, Melling RV cam. Eddy 600 4 bbl carb.
That sounds like an excellent plan for a fun street cruiser with good economy. With properly prepped 302 heads and an RV cam you should be able to run six to ten degrees of static ignition advance (vacuum gauge set to find sweet spot and limit mechanical advance for 30-32 degrees all the way in at cruise rpm in high gear. Limit vacuum advance to around 16- 19 degrees, 302’s tend to work well with 46-49 total at cruise, depending on cruise rpm. My personal experience fine tuning a friends very porky ramcharger with a well worn 87 B-250 van 318 with stock roller cam, 302 heads, eddy performer 318/360 intake and a Q-Jet ran best at 7 static, 30 degrees total all in at 2200 rpm on a constant diet of 87 octane junk gas. Admittedly, it wouldn’t have gotten by with that if it wasn’t down on compression. It was a bare budget leftover parts build and the engine had 147,000 well maintained miles on it when it came out of said 15 passenger wagon van.69 cuda notchback. 318, 3.73 geared 8.8 with locker, 42RH automatic, 68 hi po exhaust manifolds. I got the rear end, exhaust manifolds, and the V8. Still need to locate a trans out of a pickup. Plenty of em at my local boneyard, just got to go pull one.

Wow! What is your set up as far as cam, compression, and what octane? What rpm is that much timing all in at? Are you running EGR? My present 10:1 zero deck 318 begins with 675 boat anchors tries to get seriously hot in a short time at anything over 50 degrees total cruise timing, but I do have an intake gasket vacuum leak that I have yet to deal with.This^^^
It had taken me some time to figure this out on my 87 Ramcharger. The 302's definately like less initial timing than motors w/o them. My beast likes 6* initial, 36* mechanical and total of 58* all in with vacuum advance.
