Sparky can probably speak volumes on the subject if this is not enough...

The big difference is in the Intake Manifold which is a very low profile design on the Toro. But I think you knew that...

Well, im sure there isnt anything sibstantially different in their design. But id kike to have the powertrain at least orriginal components... So,if there is a difference id like to know about it... Im kinda wierd...

You might want to look for parts for the GMC Motorhome. The GMC Motorhome has the Toronado front end under it. It was made from 1973 to 1978. appliedgmc.com has and aluminun intake that I think some have used the eleldrock heads with. They also have and aluminun pan for the transmission. Don D.

Well, folks, I got the Aluminum Heads late last week and I have to say they look awesome. Adjustable rocker studs, improved combustion chamber, no heat crossover, much lighter. I am really looking forward to installing them in a week or two once the block work is complete.

Also got the Rockwell aluminum intake from Mondello in the order and I have to say it also looks truly awesome. Much lighter than the cast iron model.

I will report back on my experience once I get the engine built and the car back on the road; current target is May or June '11.

Hey, quick question... They have the edelbrock heads on amazon for about $800... is that each, or a pair? I might go for 'em for $800 a pair, but $1600 is rediculous.

I had the same thing happen to me. Mondello sells them for less than anyone as they were heavily involved in their development and their price is $1575 for a pair.

I saw what I think you saw only directly at Summit Racing for about $850... each. :(

Given the improvement in performance, the higher tolerance for modern gas and the weight reduction I felt it well worth the investment. I just checked with my local machine shop and they quoted me $499/head for a full rebuild including new valves and springs. Mondello charges exactly the same for a set of reman heads.

So is it worth $600 to have brand new aluminum heads? I will be finding out soon; hopefully by the end of this month if all goes well. I will have to make this decision again eventually as I will start rebuilding my 68 in a year or so; at that point I will have enough information and experience to decide whether the additional $600 was worth it. In one sense it clearly is; I intend to drive my 69 regularly during the summer and so I want many miles and years from it - amortizing $600 over 10 years is just $60/yr which is quite well worth it. Of course if the money is not there to begin with such rationalizations are of no use...

Hope that helps! :?

Just got the valve lash adjusted and hope to complete the engine this weekend... really looking forward to firing her up!

I'll let you know what I think but so far I am really happy with the Aluminum heads. 8-)
