do you have a chevy/GMC 6 and WAY too much money?

[yorgatron]

cool stuff but they don't show the prices www.waynemfgco.com/frame.html (http://www.waynemfgco.com/frame.html) if you have to ask,you probably can't afford it...

[briggs&strattonChev]

that 235 head looks pretty cool

[Kilroy]

Is there any TRADITIONAL HISTORY going on with those heads? I mean why would you put new heads on an overhead motor? I thought everyone ran flatheads back in the day...

Wayne equipped 6cyl's kicked some serious ass back in the day. They were run on both the drags and Bonneville with great success.

As traditional as it gets...these are a developmeny of the post-war Wayne-Hornung 12 port head for GMCs.
Used a lot at Bonneville but mostly in the old Midwestern "outlaw" half-mile cars.

I wish I had such a beautiful thing in my possesion...

[orange52]

Like most of us, I'm in the "If you have to ask you probably can't afford it" group but I am curious. Has anyone checked into the price of one of these?

These engines were how the Chevy fans kicked butt among the flathead followers, back in the day. A GMC with one of these heads, and set up with the right carbs, valve train, and exhaust, could produce more HP per cubic inch than just about any unblown engine around at the time. They weren't cheap then, either, and so weren't very common, but they were featured quite a bit in the hot rod press from 1950 - 1955.

There was a 302" GMC, bored out to 320", running six carbs on a 12 port head featured on the cover of Car Craft in Dec. '54 and Oct. '55, and the July '52 Hop Up had an article about putting a GMC in your Chevy.

Hot Rod featured a stock head GMC 270" on the May '53 cover, and had a six page article on hot rodding the Chevy and GMC six. Hot Rod also featured a 12 port GMC on their cover in Oct. '53 and Dec. '54. This last one is one of my favorite cover shots.

"California" Bill Fisher's Chevy speed manual from 1951 shows a picture of the "City of Pasadena" streamliner, with a 12 port GMC. This car was clocked at 216mph on the run when it was wrecked at Bonneville in 1950. During this same time period, these engines were being qualified for the Indy 500, though they never were run in that race; and Juan Fangio was importing Wayne headed Chevies to race down in Argentina. These are just some examples within arms reach of my computer.

Yeah, I know, for the most part, flatheads WERE hot rodding back then, just like SBC V8's are now, but some guys were making traditional history with some other types of engines.

Here's the "don't ask" stuff explained.

From memory the prices are roughly:-
The 1.5:1 roller rockers sell for $US1500,
The special pushrods sell for $US200
The head sells for $US2250
The McGruk valve cover sells for $US400.

Check out the site for the history stuff, or inliners.org for the rest of it!!

Email them if you are interested - they are flat out keeping up with demand. There are 18 aluminium heads for 236/261 chev getting machined at the moment.

I'm saving up my dollars for one such head - except that the conversion rate means that I have to pay an extra 33 to 50% AND ship it down under, so it will be some time before I get my hands on one!!!!! http://www.jalopyjournal.com/ubbthreads/images/graemlins/frown.gif

So you ask why buy one??!!

Well its like running a quickchange vs running a quickchange cover. You want a QC, so you buy an imitation QC centre section, and you bolt it to the back of your banjo centre section. Yep you fooled 90% of the people that look at it, BUT unless like being a fuckin wanker of a gold chainer, you ain't gunna fool those that really count, ie those who appreciate REAL traditional hot rods. And they'll only think of you as a wanker!!!

You want super traditional horsepower you buy a 12 port or an Ardun, or what ever does it for you. Yes it costs big $$$$$, but it strokes your ego to the max, and really ego is one of the major factors in why we build hot rods.!!!

Just my 0.02 worth as to why this little Aussie Battler is saving his bucks to bring a 12 port down under. http://www.jalopyjournal.com/ubbthreads/images/graemlins/wink.gif

yeah kinky that "City Of Pasadena" The COP car was owned by Marvin Lee, he made his living with cars, His son Larry Lee had that two tone 50 chev with the 55 chev grill. was a pretty good striper in his day

sorry to go off on a tangent!
what I've aways thought was so hot about the Wayne 12 ports were that the intake and exhaust ports are on oppisite sides of the block http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

[ikillspies]

clifford performance sells a whole bunch of chevy six cylinder shit, manifolds, exhaust, cams, heads, i run a 250ci, and i could get 3 vintage style quads, but it would be well over $3000 (heads, cam, pushrods, intake maifold, carbs, and headers) to get only a little more power than i could if i got some small block chevy for $300.

[RileyRacing]

I sent an email to Wayne, they're sending me the info. Sometimes, you just gotta say What the F**K!

Are there preferable inline 6 blocks for foundations to build on? What years are good to look for?

[Kinky6]

For the GMC 302", 1952 - 59 commercial 2 1/2 & 3 ton trucks, although these engines were often bought as replacements for worn-out 228/248/270" motors in smaller trucks.

They all had the same block. You can tell the size by looking at a machined surface to the rear of the distributor; the first 3 digits of the stamped code is the displacement.

About 50% of the 302" production went into military 6x6 trucks (duece and a half). That's where I found mine.

You could also look at a Chevy 261". It shares a smaller block with the 235", but is built a little stouter, and will take common overbores in the 270-278" range. These came in a variety of Chevy trucks from 1954-62.

Check the casting # page at inliners.org to help decipher your junkyard finds.

Hope this helps. Kinky6 http://www.jalopyjournal.com/ubbthreads/images/graemlins/cool.gif

[cheaterslick]
