Hi Everyone! Just got my first 66 Mustang!

[SwayBetty66]

Hey guys, I’m new to restoration. And I finally got my dream girl… I wanted to ask of the group what is this meanest engine I can put in her without a ton of modification? I know I will have to upgrade all rear axle and brakes from drum to disc. She current has a 250 inline 6 and C4 transmission.
I would love to turn her into a Mad Max Sleeper. Also looking to keep all mechanic not really electric anything if possible. That’s my ultimate goal…
Be gentle I’m new

Super nice car man! 363 cubic inch stroker but would have to be a Dart block due to the bore and the power level. You can build the C4 to handle it or swap out to a manual transmission like a Tremec TKX. The laundry list of parts to support the installations would be pretty big so I hope you have a biiiig budget. Another way to go is a crate motor 347 which will be less $$$.

Really what you need to ask yourself if what is my goal. You should also realize that about the widest rear tire you are going to fit under the car is a 245 but I have read where you can stuff a 255 if you are willing to roll the fender lips. I have 275/40R17 Nitto 555R's on my Coupe with about 370 rwhp and its marginal on traction. This is with 3.73 rear gears.

Do some research and I think you will find that a 302 with heads, cam, intake, and good supporting parts will build enough power for a really nice street car and a Tremec T5 will live behind it.

Your dream so figure up what you want and if budget is not a concern then go for it.

I owned and drove a 66 cyl automatic for about 20 years. Very reliable and easy to maintain. Only sold it when the 428 cj came along. Why not restore the 6 cy while keeping an eye out for the super modded car you really want? Brian

I’m trying to keep her mechanical only, I love the idea of a stroker!! Someone suggested to just keep it intact for the moment cause the engine is good but add a four barrel carb in take and a nice exhaust which probably needs to be done anyway, but that would give it more horsepower with out killing my bank account for the moment? What do you think 4 headed aluminum intake?

Modified the C4 with a Raybestos race kit this weekend. Sandblasted and repainted. Hardest part was a snap ring until I figured out the head was in lopsided

After the numbers sink in, take a look at the rest of video for the build.

They have a parts list (somewhat) in the Youtube description.

I found this while I was looking around too:

6 EFI Exhaust Manifold Turbo Kit Ford 240/300 - DFW Speed

Hot Side Kit includes: Stainless Steel Turbo Pipe that bolts directly to factory EFI exhaust - DFW Speed Syndicate

www.dfwspeedsyndicate.com

It's a different kit than the one above. No idea what numbers they make with it.
