Aluminum intake/water pump needed
 

I am in need of an aluminum intake and water pump for my 428.......anybody have any suggestions on where to start looking????? Thank you ...Scott:3DSMILE: :3DSMILE:

I suggest the edelbrock water pump. It is aluminum and comes in natural or polished. www.summittracing.com.

Manifolds are pretty easy. The best performing is the Edelbrock performer rpm manifold. It is a bolt on medium rise style 4v but of course it isn't original. Blue Thunder has repro manifolds that replicate the OEM look and provide good performance. Offenhauser made a good 4v as well as a dual quad manifold for several years and are pretty cheap these days.

Of course the most manly men choose either an OEM dual quad or a webber setup. Both are more pricey and more difficult to keep tuned. But of course you didn't come in here because it was easy. You came in here because it's cool. Dual quads and webbers are cool. A nice webber set up willl set you back $2k-2.5k and a full 8v lowrise should be about $1200-1500.

You can put together a dual quad unit piece by piece if you can deal with non oem carbs (Holley 1850's are most common) in that case the carbs are $375 ea. a nice manifold might set you back $450. 1" phenolic spacers are $50 ea and air cleaners are another $65 ea. linkage is $75. It still ends up being $1500 but in smaller chunks.

try ebay. i usually get great deals from there and find the same parts as summit or jegs.

I have an Edelbrock manifold and pump. Check out Jegs also (www.jegs.com) , they have good pricing and I found more FE parts there than Summit. My manifold isn't original style with the rear breather, but looks and runs great.

check this out!!

I agree with those above about the Edelbrock aluminum water pump. I have an old dual-carb Holman-Moody manifold which has the rear breather; you may be able to find one of those at a swap meet or on the web.

FWIW, my experience with the Holley 1850s was less than optimal. I fiddled around with them for several years and was never really satisfied with how they ran. I could get them to run at low speed or at high speed but not together. I went with the 6224s, swapped the metering blocks from the 1850s (which have the power valves) in place of the ones which came with the 6224s (which have the power valve holes blocked) and played with the jets until I was satisfied. I ended up with #72 jets in the primaries and secondary plates equivalent to #76 jets in the secondaries. I hooked up a vacuum gauge directly to a port in the manifold, duct taped the gauge to the dashboard and recorded the manifold vacuum in each gear at 1000 rpm intervals; lowest vacuum was at idle at 10.5 inches. Based on that I installed 8.5 power valves. Seems to have worked out OK but was certainly a frustrating and expensive way to go.

To expand a little on what Mr. Scobra said, if you run the numbers from Holley, you could get a dual-quad setup using the 450-cfm mechanical secondary Holleys (model 0-9776) and have plenty of carburation for your engine:

Inputing the numbers in their formula, you need about 805 cfm if you run your motor to 6500 rpm and assume 100% volumetric efficiency. The 450 cfms are considerably cheaper than the 660-cfm 6224s, $175 each versus $455 each for the 6224s.

Incidently, if you get to fiddling around with the power valves, be aware that just because the package says "8.5" doesn't mean the valve opens there. I have one of those little power valve testers and a hand pump and took it to Loper's with me when I bought the two valves in the car. We went through about a dozen before I found two that actually opened at 8.5 inches. Range of actual opening vacuum readings was from 6 to 12 inches. The guys behind the counter were a bit miffed that I did it until they saw the variations for themselves.

Also, if you elect to go with a dual 1850 setup, be aware that you will have to get the little caps for the secondary dashpots which have the nipples which allow you to hook the two secondary dashpots together, to ensure that they open at the same time. Holley wants about $65 apiece for them. One of the guys I work with rebuilds old BMWs for a hobby, and we took the dashpot covers which came with the carbs, drilled horizontal holes; inserted small-diameter stainless steel tubes and epoxied the tubes to the covers with some really good industrial-strength epoxy. It solved the opening-together problem but the I couldn't solve the not-opening-all-the-way problem. That's when I finally went back to the mechanical secondaries on the 6224s. Hope this rambling is of some use to you.
