I know these tires are a little on the "Fat Sidewall" side compared to what everyone else is running......but this car will never see a cone.....just a garage built Power Tour car......hence the wider tires......the fronts are 17 x 7 ......225 -55........the rears are 18 x 8 ......255-55.........I believe 4 1/2 back spacing ........
I finished the exhaust system and got another Education on Welding.......I finally got the wire feed and voltage dialed in on the last weld........Typical..........But.....In building the other LS powered cars I always seemed to have issues with the "Rappy" sound out the exhaust pipes and ended up changing mufflers a couple times to get away from it..........I think the length of the tail pipes have something to do with it........But.......On this car I bought Dynomax #17749 super turbo mufflers and brought the tail pipes out behind the rear tires........so ....when I started it I didn't know what to expect.........I wanted the quietist performance Muffler I could find...........so.....When I started it........I was very pleasantly surprised at how you could hear the exhaust.....but yet how quiet it was........Perfect!!!........Going down to Stefano at Nickey next week to get the rough edges blended together in the ECM............When I started the build I had the complete ZL1 harness assy........But......because I decided not to use the 6L90E trans we couldn't use the ZL1 harness ........John at Speartech supplied a ECM set up to work with the engine and the 4L70E trans......but....It needed to dialed in to blend everything together......so......Stefano and Cory are going to put the final piece of the puzzle in place.............Then it's going to Frame-Up to get the A/C system charged......83 days till Power Tour.......
I have gotten a couple of requests to hear the "Beater" run with the exhaust system.....so....here is a short video......as you can see until the engine gets tuned it's running Pig Rich!!!..........Driving down the road you can barely hear the exhaust unlike the Flowmaster that I had on the other cars......These are much better and thanks to Samhatco for the Muffler recommendation.....Click on the Picture for Video
Ken, the car looks and sounds great. I was also doing exhaust today on our 67. One thing worth mentioning is your tailpipe exits. I did my 64 chevelle like yours and experienced a lot of fumes blowing into the car at low speeds. I ended up extending them back a foot and it was solved. Seems like if you don't get the spent gases away from the car they whip around and into the cabin.

If there is a problem that will be the first thing to adjust........Thanks
