460?
#1
To start, I have a 71 vert, 302, C4 car. I know I can get some great hp from that but have an oppertunity to obtain a 76 460 with trans built to my specs in trade for bodywork on a 54 merc. Not experienced in 460 fords so questions arise.
1. How big a pain to install?
2. How should it be built? (pump gas, max hp)
I know others have done this so just looking for suggestions

I'm also new to the BBF's and the 429 in my 73 seems to be pretty well built and Ive been looking at what I can do to supplement a higher octane fuel. After some investigation Ive decided upon a methanol/Water injection system that boost octane 20-25 points helps the engine run cooler and increase HP more than 116 ocvtane racing fuel. The system isnt cheap but to me its well worth the money! With this sytem it will allow you to run a high compression engine on pump gas with some wild horse power!!! Heres the system Im looking at:

The installation is very straight forward. Motor mounts and headers are readily available.

How it should be built is totally dependent on how you will use the car. Weekend cruiser? Street/strip? Race only?

I saw an add video on that system before and of coarse they tried to sell the product but after some research of my own I found there were complications with it...before you shell out the moola I would suggest researching it yourself. I think they got it to run very well but it took a lot of tweeking, trial and error work to pull it off. They did not convence me that the trouble was worth the outcome, but if you do this system and figure it out PLEASE post it and let us know.

This will be a weekend camaro eater only. Some of my questions are concerning fit and maintenance, body mods due to torque, cooling, etc.

Not trying to insult your knowledge but I believe it is important to understand that the for all practical purposes, the 429 and 460 are the SAME basic motors. The only real major difference is in the crankshafts. The 460 gets it "extra" cubic inches from the additional stroke.

That having been said, I have found that fitment for the 1971 - 1973 Mustangs is NOT an issue. All one has to do is set the car up similarly to the 1971CJ/SCJ Mustangs. In my case, I did go to bigger sway bars and heavier springs but it really depends on what you want out of the car.

Here is a picture of the 472 (.060 over 460) that I have in my '73 Grandé:

Here is a picture of how the car "sits" with the 472, C6 and 9 inch to give you some idea as to the stance.

Yes I know the two blocks are the same, my concern as stated was going from small to big block, what was involved, and ease of maintaining it as I have owned bb fords before they were in bigger cars. I owned a 68 GT fastback 302 4 speed but this is my first 71. So basically spring change as I figured, mounts of coarse, now does the factory cooling set up for bb work well? cross member for 302 need changed? trans mount I assume is availible? I also know that frame support will be needed. Am I forgetting anything? tips? do's and don'ts would be greatly appriciated. ps don't worry about insulting me, I have no intellegence...lol

Get a griffin aluminum radiator and forget about all cooling problems!

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

I put a 2 core HO in my 68 and never had a problem again so I'm with you on that

I see used and running 460/C-6 combos regularly and have even seen a few in 71-73 Mustangs
They seem to sell for 1500-2K The 460 can be built to be a complete monster if you so desire.

I'd make sure and use a nonretarded timing set and pick a compression ratio and camshaft to put out maximum torque in the low to midrange. Since the C-6 won't have an overdrive, I'd look to run 3.25 gears.

If you plan on running it on the dragstrip leave in the existing front springs.

I want a 1 to 2 inch drop in the front anyway so thats a good suggestion. Will not be dragging a vert on the strip but I do want a fast toy.
Been looking at some jon kaase heads but not sure, does anyone have any experience with these? I believe Q just bought one.
The guy offered me the engine trans combo, parts, and machine work for trade. I think it's a good trade but what do I know?
