Looks good! Sounds good, I think its time for a drive! 8-)

The camera appears to be a wheels. Usually you can tell when someone is walking with a camera by the up & down movement. Maybe it's all done by the camera's electronic image stabilization.

Hello Folks, it's been awhile since I've posted. Wanted to share some pictures from the Cocoa car show 2014. Since then the car was partially tuned. Made 517hp and 525lbs at the wheels. The OBD 1 computer is holding back the engine. The engine is a built by Scott Shafiroff 540ci, dynode at 700hp and 700 lbs of torque. Manifold was custom made by Hogan. Almost 10 degree angle on the throttle body for clearance. Trans is a 700r4 with 3400 stall with lockup. Trans was built by Finish line transmissions , it was tested up to 1500lbs of torque. Converter is Yank. The rear is a dana 44 with 3.33. As of now I am getting over 20mpg with my foot out of it. The car is brutal. At 50 you can roast the tires with 315s. After the corvette show I entered this week Oct 18, I will be installing a Holley HP system as a piggy back for engine management. I should be able to bring the numbers into the 600s at the wheels. Instead of the batch injection it will be sequential injection. Will see better numbers and also I can hook up laptop computer to this Holley system and give out my IP address and any tuner in world with a computer can tune this car while I drive around. The Holley computer has a wide band O2 and will also self tune. Pretty wild. Far cry from the chips being burnt. If you do need some chips burnt go and give TPIS a call and ask for Jim Hall. This guy has helped me for many years. As far as I'm concerned he is one of the best tuners out there. Anyway I will try to post more stuff regarding my build. I apologize for not getting back to some of my threads. Enjoy the pictures.

Thanks, it's getting there, once it's fully tuned then I can play more. Here are some camshaft specs. Just under 10 to 1 compression. Full roller motor.
http://www.ultrastreet.net/engines/540_realstreet.php This is where I bought the long block from. It's the hot hydraulic version. Hogan claims a 50hp difference then carb. Plus the tune. It has 1300cfm throttle body with 60lbs injectors. I recommend the Racetronix company for the 10 gauge wiring for the fuel pump. Its a plug and play unit that runs under the sill and it connects to the 340lph Aero motive in tank fuel pump. I will have more pictures when I get some more time. Hope you enjoy. If you want to see some videos. https://www.youtube.com/watch?v=OeSFM_Z ... cZW31P5qpQ

I found the video of the chassis dyno very interesting. Noticed they sprayed the tires with a traction compound, which makes sense. Sounds really nice and I bet an excellent cruiser!

This must be what you are talking about, this add on to the base engine.

Rick, it is fun to drive, you have to respect it like the ocean. You can't be stupid. In the beginning of driving it, I learned really fast how not to drive it. With all that torque it's insane. But the great points are, you don't need low gears 3.33. is perfect as far as I'm concern. Over 20+ miles per gal. It will be much better with the holley hp system. The reason I didn't build my own engine is that I own a business and I don't have the time to be working on the car every weekend. Leave the trial and error to the professionals. All that R and D on the track. One of the other things I have to address is make your Big Block breathe. I tried to keep the car quiet but the engine needs proper exhaust flow. I went from Flowmaster 2 chamber mufflers which were too loud and droning. To Dynomax, Turbo mufflers which are too close to stock flow. Now I'm looking around for the correct flow and sound which is personal. Have a good evening!

About two weeks ago I uncorked my 540ci, I had 3" going to the middle of the car and going down to 2.5 Dynomax super turbo mufflers. It was a mistake on my part for listen to the sales person with no knowledge on flow. Those mufflers were like stock mufflers. The flow was piercing.
Now continued the theme with 3" the whole way with dynomax ultraflow 3" straight through with down spouts. Sounds Sick, world of difference. It's a different car all together, Now all you can hear is the cam and deep sound. Below is a sound clip at night. Hope you all enjoy it.
