Hot Rods Let's see your homemade speed equipment

I love the 'Ping-O-Matic' - looks like something I'd make . . . and then ping the Hell out of it when running! LOL

 

Here are a couple I made over the years. The first is a tunnel manifold I made for my 331 hemi in my Willys. Did this in JC in '68. Ran terrible


I cut up the tunnel ram and built a one plane intake but never ran it.

Here is a modified early Chrysler hemi intake manifold I now run on my Willys. I simply bored the intake to accept a bigger Holley carb. The factory made the manifold perfectly for this. Also brazed tubes @ the water outlets so I could run a conventional thermostat since the 331 hemis didn't use the water crossover on the front of the heads like the later hemis used.

This is an equal length, individual runner intake I cast in aluminum for my 230cuin Chevy straight. Thing worked great, engine would climb a rope!! Had to put dividers in the Siamese intake runners.

 

"Ping-O-Matic," I like that !

 

What did you make the water pump out of? Also is the thermostat housing just two water necks back to back?
Great work, this is real hotrodding.

The water pump is a stainless steel 4" centrifugal pump I found in the junk yard. Had to make a new aluminum snout and shaft on the lathe. Played around with various impellers. Started out with the stainless one that came with the pump but it cranked out WAY too much flow/pressure. Finally adapted one from a car water pump. Those are much less efficient that the industrial impellers so moves the volume with less pressure. The thermostat housing was welded and brazed from steel pipe with a parts store (Chevy?) neck on top.

 

Here are 3 GMC 270/302 intakes. The 3-2's were for 97's which I converted to Holley bases. Was made to clear Nicson cast iron headers. The single 2 barrel was found a a swap meet for $10.00 with a Brazwell 2barrel Holley it ran 163 @ Muroc in 1997. The last is an injection unit I got from the Burce Johnson estate after his passing. It was for alcohol as I see the nozzle ports and I don't think it was ever finished.

 

My buddy Frank made the linkage and fuel block in his home workshop. Also adapter plate motor plate and stuff to numerous to mention.

 

Starting another manifold and again it will run twin single barrel holden stromberg's. After trying different combinations of double barrel carbs, a 4 banger screams with these single barrels. The first manifold I made had straight through pipes for the track but this one will be a bit more sensible and go through a muffler. Decided on the victory pipes because I think they look cool.

 

Bump

 

Joelorocknrollo..did the same setup on my Banger started and ran like a dream.....

 

I converted a stock Model A intake to run a 1 3/4" SU carburetor. Also made an old school set of headers from two stock manifolds. Pretty primitive, but...

 

That's pretty cool!

 

That is killer!
In the old days that's how innovation got it's start!!!

 

I love this thread! Can't wait to get my act together so I can post something of worth

 

My headers. I just started a build thread so I don't clog this one up.

All gas welded with my 1940s Purox torch. Don't mind all the junk in the messy garage. Hopefully someday I get my act together and have a clean place to work. Not sure how it happens... I start working on something and before I know it the place looks like a bomb went off! Anybody else have that problem?

 

Almost everything I have is homemade.............and is designed with mechanic in mind

Nice Job!

 

Just finished this intake for a 302 GMC. Made patterns castings and machining

 

wow, this is a great thread. some of you do just great work. it's double-great to see motors that aren't the usual suspects. I suppose I'd buy performance parts if it was possible.

my Rambler 195.6 OHV (the OHV version of the pre-64 six) has been nicely built by a local big-block race engine builder, I'm on my second carb upgrade. it's a trough head, so adapting is easy.

made this blended, cross-section-matched manifold to bolt onto a two-barrel trough plate that I'd milled out so match the area of two 44mm bores of a Weber IDF 44.

(can't seem to fix image; it shows in preview, but not when i save... oh well.)

 

The Don Rounds N.A.S.C.A.R Sportsman built in the late 50's early 60's now owned by Mel Ogden of Franklin N.Y.

Check out the flex pipe headers-

 

An intake I built for my crossflow-headed Ford six. The runners are tapered and turn and are symmetrically opposed so I a made wood dies to hammerform the runners.

Also, a set of stainless headers. And a valve cover.

The car runs 147 mph in the quarter.

 

Can't even come close to some of the stuff you guys on here turn out. But here's my offering...... Built these to bolt on the stage 2 heads on my big block Buick in my 55' stude.

 

Here's a couple I've whittled out. The distributor is for a 392 HEMI- it's been on here somewhere in the past. The 4 port fuel injector is currently underway and has a build thread I've been updating. Both have been super fun projects! It will have some of the sharp corners smoothed over before I call it done.

 

Just a mild modification since no-one builds an Air gap for a Quadrajet .

 

...part of a looong boring story, re-installed the previous carb, a Weber 38/38 DGV, after finding out the hard way that the 44 IDF i spent four months trying to tune was simply too large (ask if you care). i thought i knew how carbs worked but man, i had to work stuff up, again, from first principles...

anyway for the 44 IDF i had modified a scarce 2-barrel trough plate (mounted the sole factory "performance" option this engine ever had -- a Carter WCD two barrel), enlarging the Rochester 2G/"small Rochester" base to one with nearly 4 square inches of opening.

the 38/38 DGV has a two-hole pattern similar to, but completely different from, Rochester 2G, so what looks like two parallel tubes here is actually approx. 10 degree "vee" with the two holes overlapping at the base.


here's the bottom end, up. i sliced the two tubes diagonally with a hacksaw, MIG welded the parabolic gap, shaped it with a die grinder, and used JB Weld as "body putty" to make it smooth (it holds up to gasoline well, long term).




fabbed all the little stuff (throttle bracket, etc) and it all worked out great. got it jetted and tuned in one afternoon.

 

... in parallel with this, i've been working on a good PCV system. this was a road draft engine. the factory tacked a crappy PCV on it in 63? i think which did a great job of applying a fine oil mist to the intake. to make yet another long story short... the factory scheme sucked crankcase fumes from the old side cover location. i sealed that and put a more-complex-than-it-appears baffle and expansion chamber in the valve cover. that removes most of the mist.

the tall white oil filter is my Rambler-Mentality (CHEAPSKATE) catch can. took some effort to find one without an anti-drain-back valve, and tall. good catch cans are $200! no way, when i can make my own, or better yet, adapt no-brainer stuff to the task.

on the left, the little blue PCV valve is part number PCV1234, the lowest-flow i could find (1980 honda civic). the cylinder it's grommeted into is the expansion chamber, packed with bronze wool, under which is a hole, covered with a large baffle tacked inside. it's hosed to the "oil filter" on the right, below the oil filler neck. the outlet is plumbed to the center of the intake trough.

No fancy "intake manifold" for me! a trough, like Grandpa Nash intended!


ask me in a year if it worked out.

 

umm your carburetor is may be a *wee* bit bigger than mine.
