Re: Water Pump Re-builders here at SYC?
 

I just got off the Phone with Chris at Authur Gould. I accurately described thd engine, the tranny, the engine modifications and the radiator modification.

Chris recommended a hi flow impeller. Pump is shipping tomorrow. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Have you considered running the L-46 camshaft out of the Corvette?

I own a L-79 in my 67 Vette and love the engine but given you have a 350 it may be worth reading. JMO. </div></div>

Yes! The cam I decided to go with is a hybrid cam made by Comp Cams that is called the L-79 &quot;Nostalgia Plus&quot;. According to Comp Cams this cam is the generic replacement for both the L-79 and the L-46.

Replicating the L-46 is a more accurate target when describing the build for the Z-11 rebuild, so you are exactly right. I made reference to the l-79 cam as that is what it is commonly called as the L-46 is a lesser known engine in general circles.

Sal,

The CRG has an associate member named Alan Colvin who wrote the series &quot;Chevrolet by the numbers&quot; If you have the 1965-1969 copy look at page 102 for usage applications with head 3927186.

It was made with both 1.94/150 or 2.02/160. Lower horse applications like my car got the 1.94/150 from the factory.

Alan's CRG BIO can be found here: http://www.camaros.org/aboutcrg.shtml#Members </div></div>


Yep! I have his book--- just saw it. States that the #186's were possibly used interchangeably! Must be something rare to have these heads though. Maybe when they were assembling the engine they were short a pair of the #041's but who knows. Still neat!!!

Thanks,

Sal,

My original 186&quot;s were valved for 1.94/150 (low horse) and I have a $900.00 bill from the machine shop for the conversion. It is funny to me that this would be considered a rarity as I have been looking with a focus on late production pace car small blocks for decades-and double hump heads were present in a significant portion of this population. So much so that I honestly did not give it a second thought as to the relative rarity of the head usage.

Re: Water Pump Re-builders here at SYC?
 

Good luck with your engine build! Have you posted pics of your car on here? Would like to see them! By the way, I am currently running the #041's on my '69 SS but my block is a 1969 HC coded block (originally came with a 2 BBL, 250HP and manual trans.) but the engine is running a nice cam and has 11:1 compression. I guess it's safe to say it's got some mild work done to it!

Re: Water Pump Re-builders here at SYC?
 

Sal,

It is pretty much all done.. just waiting for some good weather to break the rebuild in properly. Externally this is 350/300 with TH-350 so the air cleaner is kind of specific to this application with the ThermoAC warm up valve including manifold stove with pipe. Since the car is original and I have owned it for 25 years it still has some very neat untouched original stuff on it... check out the Fuel line to fuel pump hose.. &quot;GM GAS D03369&quot; [img]<<GRAEMLIN_URL>>/beers.gif[/img]

This is a driver.

Re: Water Pump Re-builders here at SYC?
 

Here is the 21 inch 4 core radiator that I had custom made for this build.. its street manners and overall driveability should improve.

Modifications to the original engine:

186 heads converted to use 2.02 valves
Roller rockers
L-79 350 HP Cam
Keith Black hypereutectic pistons
Eagle Rods
GM 1187 Steel Crank
302 Z/28 windage tray and Z/28 pan with the internal rails
High flow impeller modified water pump

Trans input: Hughes 2000 stall converter.
