Exhaust
-Headers, waiting to see what FM comes out with (it's weird using the plural form of the word haha )
WASTE of money! Look at the Sanderson headers that are now made for the V8r kit. Also, a company now sells a full bolt on stainless steel exhaust for your kit. I bet the FM exhaust kit will be over $2k!

Part number for the headers: Sanderson Headers LS150M (Price is $350 I think...)

http://enthuzacar.com/ makes the bolt on exhaust. Its true dual/stainless steel/under $1k last time I called them...Stainless is more

-Speedometer solution
Bam! http://www.jegs.com/i/Cyberdyne/280/C270E161N/10002/-1

I can keep going lol ;)

Also, call FM and buy the heat shields for the motor mounts ASAP!!! They are $34.95 for the pair and will protect your motor mounts from melting. Mine started to melt so I need to drop the subframe again. I guess FM had this issue on a few cars as well.

I'm also building a V8R, LS2,T56,Getrag 3:43, one area to watch is the relocation of the raditor. It needs to move forward several inches, along with the front sway bar. Also pound some extra speedometer connector clearance in the tunnel. You will be glad you did later. It looks great. Good luck.

^^THIS guy rocks. You and TurboTyla have been a huge help with questions I've had on the swap or just the motor in general and resources that I hadn't encountered until you linked me to them--thanks!!

I have a little bit of a surprise planned for the exhaust, but it's good to know about the headers AND heat shields!

I'm also building a V8R, LS2,T56,Getrag 3:43, one area to watch is the relocation of the raditor. It needs to move forward several inches, along with the front sway bar. Also pound some extra speedometer connector clearance in the tunnel. You will be glad you did later. It looks great. Good luck.
What made you decide on the 3:43? I'm not that fluent in gear speak but I asked around and thought the 3.73 would be ok, but someone the other day mentioned they thought I was just going to fry the tires off with that gearing.... lol.
I'll see how the rad works out, since I won't have A/C I figured if I needed to I could use the extra space in front :) Thanks for the heads up on that and the speedo connector!

I'm trying to restrain myself here, but I'm afraid I just can't.



:mrgreen: Awesome build Jess! Best of luck!

Thanks for all the comments guys. I'll try and make it as badass as I can ;)

I think the hardest part of all this is keeping track of the people I encounter along the way who want to see the car when it's done, lol.
