Aluminum heads

Hello I'm building a early 70s 429 for my 79 F250 that I'm in the process of restoring. The engine came with D0VE heads which I'm pretty sure will require premium fuel. I don't want to run premium because it's not available in my town (I know right?). Anyways what would be my options for running a Aluminum head with a slightly larger combustion chamber. The engine will have stock type rebuilder dished pistons, a Edelbrock performer rpm intake manifold, straight up timing set and fairly mild cam. It's going into a truck so I don't need crazy HP just reliable torque for pulling and daily driving. Also they need to have the stock exhaust port location. Would the Edelbrock performer RPMs be a good match for this or are there better options? Any feed back would be appreciated.

Or maybe I should just find some D3 heads? I would like around 400hp if possible without sacrificing to much low end torque and usable towing power.

I think that if you're willing to do a little work on your D3's(following Scotty/Mad Porter's instructions) they can reach your performance goals without a whole lot of trouble. They won't look as fancy as aluminum heads but they are a heck of a lot cheaper.

Thanks for the feed back. What kinda compression ratio would I be running with D3 heads and stock rebuilder type pistons then? I want to use 87 octane.

You can purchase heads with 95cc chambers, pretty sure you can get trickflow 290s with a 95cc chamber? Then have the block zero decked to the proper cc piston and you can run pump 87 all day long!

Do these heads have the stock exhaust port location?

No they're raised .270" if I'm not mistaken? I believe that is just the floor of the port though? CJ style headers will work with these heads.

If spending 2200.00 on a set of heads is a non issue then go with afr heads. You can still run your pistons with the low lift cam. The way it was explained to me....these heads flow so well, so efficient that they actually make a small cam act bigger.....story short, 400hp really easy, torque for days, no hassles with porting old iron, your headers will bolt right up. Get with vendor on here, there are a couple that handle them.

I run 95cc Edelbrock heads in my truck and with a mid cam and Eddy manifold I can top 400 hp and run regular gas all day long. If I remember they cost me about $1800. for the set and I figured after porting and polishing D3's I'd have the same amount of money and less weight in the Edelbrocks.

What's your altitude that the truck will normally run at? The higher the altitude, the more compression you need to run in order to make the same power as it would at a lower altitude.

Thanks ya that's what I was thinking. I've never ported a set of heads before.

Based on the intended performance goals of your build, I don't see why you need to spend thousands on aluminum heads. Use the correct engineering revision production 460 crankshaft with 95cc D3VE heads with 93-97 460 pistons and you will net about 8.9:1 with zero deck, and with 88-92 460 pistons about 9.5:1. Bowl blend the D3VEs and use good stainless valves, you don't even have to grind out the 'smog bump" if you don't want to (in the case of this build). A Performer RPM is not the best intake for your intended application, and a standard Performer (non-RPM) is better suited. Use a recurved Duraspark distributor, good carburetor, etc. The cam is the final decision and will be decided upon once you have settled on the rest of the parts combo, but assuming something like I described you could make at least 350HP/500TQ...or more, depending on the cam profile.

If you are not into chasing around trying to find the iron heads that have been mentioned and you're not sure about doing bowl work etc. You should get with the Mad Porter (Scott Johnston) on here and he can get you what you need with the least hassle. He is an AFR dealer and I would agree they are the best bang for the buck in 'todays' aluminum heads. It will also shed 40 lbs off your setup. Scott can also provide a cam specific to your application. If your '70's 429 is a 72 or earlier it probably has a point distributor. The Duraspark is a oem electronic distributor that Paul Kane refereed to and would be perfect for your situation. The Duraspark II came out in '76 I believe. You would need to buy a compatible coil and the timing box for the Duraspark, (Maybe already in your 79) but once it is set for your motor it is almost a set it and forget it dealie. When you get into this stuff it always cost more than what you think. Put a budget together and add 20% and you should not have too many surprises after that. The AFR heads and a cam specific for your application will well exceed your expectations. By the way a rebuilt oem Motorcraft distributor can be had off of eBay for less than $60. I just bought one, it is what the man says it is and it looks like a good piece. You might want to ask Scotty how an Edelbrock Air Gap would work for your set up. Good luck.

Cool

Any re-manufactured (Cardone does ALL of them and supplies are running short) OEM distributor whether purchased off of Ebay or at your local parts store WILL HAVE TO BE PROPERLY CURVED.

This also applies to any aftermarket unit as well. MSD, Pertronix, HEI, ad nauseum...

The advance curve's in these units are all over the place and simply setting one in with out checking for total timing based on combo needs is a recipe for disaster or a piss poor running engine.

Spinning a dizzy on our sun machine and getting it right cost $100.00 plus return shipping or we offer reman's at $181.95 custom curved.


Thanxx for the good word colt.
