That stock cast iron intake you have will work as well as any aftermarket dual plane in your application. Do your best to port match the intake ports on the heads to the larger ports in the intake.

My 920 heads are 3/8 intake bolts

Apart from needing unleaded seats for the exhaust valves the 920 head is a good closed chamber head and will work great on a mild build 318

You are going to need to track down a V8 centerlink, exhaust manifolds and motor mounts and brackets for an early A-body. Is the car 3 on the tree or something? I would keep it manual shift if it were me. I warmed over 318 will make that car plenty fast enough for a cruiser.

Nice work. Amazing how much time you can spend porting. I did a garden variety performer 318-360 and mostly concentrated on the port openings and maching them with heads. It went on a 318 that I had seriously reworked the ports on. I must have raised the roof on the intake ports close to the...

The bolts up front by the water outlets on the heads tend to corrode. I have reused all the magmun intake boltson jobs I have done. They are not torque to yield.

You need a spacer under a TQ to keep the secondaries from hitting on a street dominator. At least on the big block ones I have.

No, it is a direct fit

SP2P is meant to be on a stone stock motor. I bought a truck that someone installed an SP2P with a 600 eddy carb and a cam and it is not a well thought out combo. I have a 66 273 commando intake I am thinking of replacing it with. The 318/360 intake on the 318 in my Dart runs great and only cost...

I have a performer 318/360 on a 318 with TQ carb and it runs strong. Stock bottom end with a 220°@.050 .450 cam. Heads are home ported and manifold is port matched. I paid $75 for the intake and would not pay the extra dough for a performer RPM intake. I bet the regular performer will have...

Not sure if you can use your flat tapper cam in that roller cam block

I am curious on how much my 318 would make. It is a totally stock 81 bottom end. I did a massive porting job on the heads and port matched the eddy 318/360 performer intake. It has a 210° @ .050 duration .450" lift purple cam and 73 Thermoquad off a 440. Stock electronic distributor and orange...

I like the stealth intake. Nicer than the edelbrock 318/360 performer and probably better suited to your needs than the rpm.

I have the .450 lift 250° purple shaft in my 81 318 with totally stock short block. I ported they hell out of the heads and port matched the intake and run a stock electronic distributor and orange box. Intake is an edelbrock performer 318/360 and 850cfm TQ carb. Motor pulls real hard but I run...

This is my truck with the soon to be not leaky 318

The front looked normal. Had blue rtv the length of the pan rail gaskets as well as the rubber seals. It will be fine when I am done.

Too much rtv if you ask me. Whatever the previous owner/mechanic did, did not last. I drove this truck home from Seattle to Delaware, glad it did not fail on the way. Happy I dont have to do the rear main too.

I was leaking large puddles of oil out the back of the motor. My first thought it was the rear main seal but the leak seemed too big for that. Well I pulled the pan to have a look and found this.

If you want a book that goes into theory pretty deep a real good one is "Smokey Yuniks Power Secrets" It is not mopar specific but his descriptions of how the individual systems work and how they work together applies to all pushrod V8 and many other motors. A lot of the examples he uses are...

The weiand 8007 action plus is a nice two plane with spreadbore flange.

If you have access to a good mig welder you can get the stud out. Flux core wire will not work, you must use argon to get the weld to stick. Weld up the end of the stud so you can grab it with vise grips. The heat of the weld will help loosen the stud.

A small block mopar 360 would be much easier. If you like doing major fabrication the Chevy engine could be made to work but it would be better suited to a nova or Malibu.

I say 350

The six pack rods are a big block thing and won't be in a 360. Motor home transmissions often have extension housings that won't work in passenger car applications. The internals of the trans can be used for the heavy duty planitaries but not really neccessary. I would look for car stuff if you...

Buy another set. Once they are galled like that they will only get worse.

That marine intake looks a lot like a 273 commando unit. I have an SP2P on my '68 D100 and I'm not impressed. I hear they work good with a stock or very small cam. The 318 in my truck falls flat on its face just past midrange. I did not build the motor (came in the truck) and have no idea what...

I have an edelbrock performer 318/360 on a cammed low compression 318 and it runs great. The cross section of the ports is a little smaller than the ld4b so velocity is a bit higher on the smaller engine.

If you are running double valve springs with a high rate having pressure oiling to both ends of the pushed is good.

Are these 3/8" stem or Magnum size valves?

Only one I can think of is the 66 273 commando intake.
