408 is finally in

I would love to see a list of the specs on your new engine, including heads, cam mfgr and profile, etc. What were the goals of the build? What's the target horsepower?

Thanks!
Garth

Looks like awesomeness was the goal.

Love the fuel injection on these motors. What did you go with for engine management? I will follow this thread -- so please let us know how she runs when you get everything dialed in. Curious how long it will take to get the fuel map done and what your technique will be.

Thanks for the interest in this motor. I found a pristine 4 bolt main 351C block that was hot tanked and magged to insure integrity and then added a scat/probe 408 stroker kit with flat top pistons. After talking with Dan Jones ( what an amzing guy) and reading about his stroker results, went with his suggestion to use the 4V CHI heads so I could reasonably go with a 10:5 compression ratio using California's 91 octane fuel. The heads were ported and ISKY ground a custom hydraulic roller cam that spece'd out at 621 int and 631 exh lift and 298 and 304 duration respectively. Lobe seperation is 110, which should help with the compression ratio. Also, from what I saw in similiar 408 stroker motors using CHI heads, they flow so well that you don't need alot of ignition advance, which also helps deal with poor gas and 10:5 C/R. All the machine
work and balancing was done including using the oil restritor kits, an extra oil line from the front of the motor to the back and drilling an extra oiling hole right above the cam/distributor gear. It was the lack of these precautions ( and poor oiling of the crank and bearings ) that the 393C stroker, formerly in my car, threw a rod at 6700 miles.
As far as the Hilborn injection, it is the same unit that was in the car and has a small box for adjusting about 8 differnet settings, from idle to WOT and is very user friendly. It worked great, even with multiple vacuum leaks in the hoses.
As far as power, I'm expecting ( from what similiar motors made in Dyno testing ) 540-550 hp at the crank. I've also bought the Big Throat Mufflers fom Jerry at PIM to reduce exhaust restriction, so it should sound really mean. A special thanks goes out to Dan Jones, Marlin Jack, Jerry at PIM, Tommy at Extreme Pantera,
Dennis at Perf Pantera and all the great contibutors to the Detomaso Forum threads that added so much help. I can't wait to get back on the road.

Carlsbad Car Guy I am also in the beginning stages of building a 408C. I am very interested in the additional external oil line you added. Can you give me more details? Sizes? Where to drill? Etc. I will be building this engine myself. I have sucessfully built two strokers in the past (347, and 432W). This will be my first time with a Cleveland so any advice you can give me is much appreciated. Thanks

Nice collection you have there ItalFord:
- 72 Pantera #3165
- 68 Ferrari 365 GT 2+2
- 73 Maserati Bora
- 67 Mustang Fastback
- 67 Mustang Conv.
- 76 Cobra II

How about some pics?

here is an old pict of the 365. I can not figure out how to attach more than one file at a time.

Very nice cat! I love the hilborn setup.

Hey Mike, I'm the guy that sold you the heads (Jim). Car looks awesome. Are you going to dyno tune it? Good luck and keep us posted.

Gorgeous! And it's PLY yellow too (Pantera Light Yellow)!

You can post multiple pictures if they're hosted elsewhere online, then use the image icon to add the link tags, and the images will appear in one post. If attaching the picture ot the post, you need to make multiple posts.

Thanks Jim. I plan to have it dyno'd soon after I have few miles on it. By the way, thanks again for your follow through when the postal service screwed up the shipping. Also, the heads were everything you said they were... nice to do business with an honest person !
