I have a Giant aftermarket head and wondered if aftermarket heads come painted or just raw metal? If they came from the factory painted, anybody know what a Giant Powerhead color was?
Giant was Western,Auto if memory serves me.
I've seen a couple in red, but there was no sign of it on mine. I painted mine black
One good thing is that you can pick out 'GIANT POWER HEAD' in silver so everyone knows.
I think the Giant was a Haibe patent.
Another good thing is that it works well. Feels like the 30% extra power advertised.
Will maintain 30mph up hills that used to slow the car to 23.
I recently saw a NOS Ricardo head out of the original box. It was a dark orange like the one posted above in the attachment. I have a Giant Power head I plan to put on my '25. I just haven't gotten around to it! It's black, but that doesn't mean anything. A little silver on the raised letters would be nice.
If you ask our Martin Vowell for his thoughts on the subject, PURPLE is the color you need.
With purple you will increase your top end by 10mph, It's a panacea for all stomach ailments, will remove warts and grow hair.
Once painted purple , you will be entered to race Martin and his noble steed. The semi-famous Sylmar Purple Headed Flyer .
Who'll be the first ???
Mine is red.
Mine is (not Chevy, not Hemi - thank you very much)... 1952 Ford Flathead red, Bill Hirsch engine paint color.
I have a friend that collects Western Auto store stuff of all kinds.Huge collection NOS.His family was in that business.
I left him a message to see if he has a NOS T head.I know he has one for a Dodge.Maybe same color.
I have been running a Giant head on my 13 for approx. 10 years. It seems to perform better than a milled low head that I ran prior to the Giant head.
I assume the Giant head combustion chamber design is the reason for improved performance as the compression does not seem different compared to the low head with .060" milled off.
I laid the Giant Power head and a Z head on my work bench upside-down, and the combustion chambers looked exactly the same. (The Z head was patterned after the Giant Power.) I measured the depth of the chambers, and the Giant Power was 1/8" deeper than the Z. So I had the GP milled 1/8". I knew that would be OK, since I had just removed the Z from my engine to be replaced with the GP. I needed to remove a slight amount from the combustion chamber edges using a die grinder after milling, since the chambers tapered in a bit. No problems after that, and it runs great.
George, my head is purple because I always repaint it a different color with rebuilds...as I recall you didn't like the green it was previously either...but still, it does look nice if you paint all the head bolts silver and the engine grey....my excuse is, hey I'm an artist.
You've got to admit, it is a pretty engine
Yeah I know Mart, just poking fun at your whimsey.
Martin, That looks fast!!! And Great!
Marty, I always can recognize a picture of your Head>
