Which fasteners holding the exhaust manifolds to a 67 273 head go into the water jacket? I'm removing my manifolds for beautification and don't need a floor covered in antifreeze.

I had to change my pushrods and install locking adjusters on my valvetrain, the installed pushrods were too long and the adjusters were backing out. Here's a couple photos of my Smith Brothers locking adjuster install. Car is back up and running well just as winter is ready to set in for us:-(

I read the information via search but in the interest of getting the most from my little motor I pose the following questions. I am interested in installing an oil catch device between my PCV valve and my intake manifold. In researching that, I came across the Wagner dual flow adjustable PCV...

I am planning my next build. I saw yesterday that the 88-92 318 motors have roller cams. I am thinking that would be a good place for me to start with the motor for the next build but I have questions. What do I ask for when shopping for one, are they fuel injected and it they are can they be...

The build: 1967 273, Stock heads, 10.5 Egge pistons .040 over, Lunati matched cam, hydraulic lifters & springs, LD4B intake with Holley 4160. Duration @ .050-IN 213 EX 220 lift IN .454 EX .475, LSA 112. About 2 hours total run time, 150# compression on last check. The tune: Stock distributor...

Engine, 67 273 with lunati hydraulic cam & lifters & stock adjustable rockers. When adjusting valves to zero lash + 1/2 turn, I can feel the plunger movement on some lifters & the plunger feels rock solid on some of them. Is this normal? Just go to top of plunger movement +1/2 turn, run until...

My research has shown how the shafts are supposed to install, thank you knowledge database! My spidey-senses started tingling about my 273 hydraulic lifter startup and break-in. I pulled both rocker shafts to check for correct orientation. I know notch to the left hand and down and so forth. My...

I am getting ready to start my 273 for the first time and need to prelube it. I know the top end only oils at certain degrees of the crank/cam. I have a degree wheel accurately placed on my dampener and should be able to put it to the exact degrees needed. I also have a mechanical presure gauge...

Here are a couple photos of the same part from my 67 Barracuda 273-904. Can anyone tell me where it goes please? TIA-------------------------DR----------:coffee2:

My harmonic balancer is a post 71 model going on a 67 273 so the timing marks changed. Below is my solution using my homemade installer. I marked TDC using my piston stop and am keeping the stock timing marker. I installed the summit racing timing tape per forum suggestion. As I have to pre-lube...

I am about ready to prime up the oiling system in my 273 which is already installed in the car. Will I have any trouble getting my priming shaft into the oil pump with the engine in the car? I know to put a gauge on the block and rotate the crankshaft while running the priming drill with the...

I want to use the set of Cal Custom valve covers I have refurbished and powdercoated but they are not baffeled inside. I am worried that without baffeling the PCV valve will suck oil into the intake system. Any suggestions on how to solve the problem without ruining my refinish job? Thanks for...

Took half a day off work today to marry the transmission to the engine. This is the result. My custom engine cradle worked like a dream, assembled them in opposite side of shop where I had room and set unit in the cradle. Then just pushed it over by the car for the fun tomorrow. I will post more...

Had my LD4B machined, trued and ready to put on the engine. Last night I set it on and about had a panic attack. It would not seat up, thought I mis-matched the generations. Turns out the block has roll pins front & rear for indexing the stock intakes. The Eddy does not have the holes for the...

Assembling my engine last night. I installed my 67 273 timing marker on the water pump and it put the stationary degree indicator on the passenger side of the engine. I put my piston stop on and found TDC and marked the harmonic balancer. All the advance marks engraved into the harmonic balancer...

Installed my Innovate LC2 air/fuel mixture setup this weekend. Got the gauge and processor mounted and have the wiring all figured out. I am trying to plan for the routing and fastening of the big cable that runs from the sensor to the processor. The exhaust is not installed yet. Hoping to get...

Getting ready to install & degree my cam & check valve/piston clearance. The attached card shows my cam. I have a lower sprocket 4+, 0, 4-. Is the card telling me it wants to be installed with the 4 degree advance or just where 4 degees is in relation to the TDC of intake lobe? What will the...

67 273 build data with 10.5 CR Egge domed pistons. CR Data gathered: Combustion chamber volume 62.5 CC measured. Bore 3.665 Stroke 3.31 Head gasket compressed .028 Head gasket bore 4.14. Measured cylinder volume with piston 1/2" down in cylinder = 84 CC. Rod length 6.123 Intake closing point...

I am getting ready to assemble my engine and after reading a couple threads on cam/TDC timing I am getting concerned. Below is the spec sheet on my Lunati Hydraulic for my 273/10.5:1 pistons, LD4B with Holley 4V and stock converter 904. This mild little cam should do fine with a stock converter...

I am getting ready to assemble my engine and need to file fit the rings. Can someone put me on to a good ring-squaring tool for a 273 + .040 bore so I can check end gap? Saw the roll of tape idea and the $50 one on summit, just looking for options. TIA-DR:coffee2:

My engine is ready to put together with the 10.5:1 Egge pistons. My machinest milled the heads just to clean, about ten thousands. The block was not decked at all. The new head gaskets are about sixty thousands with the universal big bore in them. I really don't want to loose that much...

Can I install 1.6:1 roller tip rockers on my stock shafts and gain duration and lift without reworking everything? The heads are together and the engine is ready to assemble. TIA, Rat:-D

Picked up by heads today. Finished with the Lunati springs & matching 10 deg retainers & keepers. New SS exhaust valves with hardened seats. I took the oil pump intermediate shaft in for inspection & hot tank and it passes muster. My question is should I go ahead and replace it? I heard they...

I need advice! My engine is in for rebuild and thinking about the oil symptoms before I pulled it it seems possible that there is a crack between one of the oil galleys to the rocker assy's and an exhaust port. The plugs all had a clean burn pattern as did the valves but on startup it...

Well I about wore my brain out but finally decided to go with the Lunati 401 hydraulic lifter setup with matched springs, retainers & keepers. I am planning on running the stock pushrods and rocker assy's. The question I have for the forum is will I need to make any changes to the oiling system...

I am taking my block & heads to the machinest this week. 273 being built with 10.5:1 Egge pistons. Does anyone know the max safe cam lift with this combo using the stock rockers? I will stay with the stock sized valves but am thinking about going to a hydraulic lifter setup with matched...

I tore down my 67 273 today and it appears to have solid lifters. Have any of you come across a stock 2V 273 with solid lifters before? I am flummoxed. It is going in for the Egge 10.5:1 rebuild with new HP cam and all the goodies so it really doesn't matter, just curious. TIA, Rat:read2:

Can anyone decode engine block casting #1737929 for me please?

The 273 is on the floor finally. I am thinking after talking with the machinest of using a 1970 318 builder block with the 273 heads and solid isky e5 cam at about 9 1/2 compression, decked & heads straightned. I am going with a 2800/3000 stall converter, built 904 with 8 1/4 3:21 locker rear...

A co worker has a 318 with a 340 crankshaft installed that I can buy cheap. What is the difference of the 318 with stock crank and with a 340 crank? TIA, Rat
