Technical ***June 2021 Banger Meet Thread - How's Your 4 Cylinder***

RailCar,
I got the carb heater form Imperial Speed and Custom in Washington state(?) a few years ago.
I have checked for full throttle, all good. I learned that lesson years ago

Thanks Phred, going to fab up a hot water manifold heater, I ice something awful when the air is cooler. I don't use a facet, I use a carter rotary electronic pump, P90091,they provide consistent pressure with no regulator..its set at 2 psi.. ticker pumps are dicey when it comes to pressure, if you catch too much it overcomes the float.

 

Need some help here. As the photo shows, the first rocker has a gap and the push rod isn’t centered in the hole. Tried tightening the nut on the end to no avail. This is an original 1935 CRAGAR head.

 

Pull pushrod,roll it on a true surface

 

Rocker arm looks bent from that angle.

 

Note the gap at the end of the rocker shaft. I’m thinking that there needs to be a spacer on the left side of the rocker and then the push rod will be centered. Rocker is not bent....camera angle is bad

 

might just need a shim or wave washer between rocker and stand

how does geometry look?

you can fire it up with the cover off, see what's going on..

 

How does it look on the valve end? Will a spacer put that end out?

 

Welp, the 3D print came out sorta decent. Got a LOT of work before I can start having them cast!

 

Looks good to me, however I think Cragar had it right... vertical cooling fins will likely slow your top speed by several mph from wind resistance, haha.

Unless of course, you chrome it. Everybody knows any chrome part is good for 3 mph.

 

Your 3D printed part looks to be the exact size of the Cragar - it needs to be larger to allow for the shrinkage when the metal solidifies - aluminum shrinks 6%, iron 10%.

Due to a lot of conflicting events the turnout was low for The Santa Margarita Ranch Time Trials (the last of F.A.S.T. sanctioned). But it didn't hold back local spectators! Fortunately for those who didn't show up they didn't suffer the premature failure of the timing equipment. This caused the event to quit shortly after lunch! Friday some of us were treated to the arrival of our host's new acquisition; and that evening a "Cruise Night" in the village. I caught these shots on my cell phone!

 

This is simply something to stand out and not be "cookie cutter" I'm curious in a hot rod with a full hood if it will affect it.

 

Correct, this was just a mockup print to see how it would look on the engine. I'll be scaling it somewhere between 6-7%. Just need to clean this one up first.

 

Did you talk to them first? The foundry I use will not cast in holes like your mounting holes. If I am using an existing piece I make up aluminum plugs the same length as the thickness and put a center drill mark in the plug on my lathe. Them press them in. That way I can just drill out the holes on a drill press without measuring.

 

To be honest, no. I'm still searching for people to cast them. That's pretty smart about the plug, I'm going to have to try that!

Do you recommend any foundries?

 

Of course it won't make any difference, I was just being goofy. Tongue in cheek foolishness.

 

There will be no goofiness in this shop.. I remember this one gypo truck shop I worked at for a cat named***** Mayo, he paid overtime in cash (loved it, hand the wife the check and pocket the dough). We were a bunch of fast movers, knocking***** out as quick as it came in. His favorite line was "I don't care how you do it, just make it go away"...he paid us early on fridays and we'd start gooning up.. acting like a bunch of fools, talking***** and grab****ing..somebody would sneak out and buy beer,hell we'd end up there half the night..

Check'n in!

We first received a rejection letter. But as the news spread through our "PreWar" racing Group that we'd been dropped after two decades of running; apparently a lobbying effort resulted in this:
