I'm sure there are some of you out there that have done this to similar cars and have some questions to ask. 1) Are there any firewall clearance issues? 2) Any transmission clearance issues? Have to cut the hump out at all? 3) Obviously have to make a new cross member. How did you build yours? 4) Motor mounts, most likely have to make my own? 5) Where did you put your computer? Any other tips or tricks would be much appreciated Thanks, Mike

I have an '03 engine out of a 2500 truck, can I only use an '03 harness because of the throttle position sensing box? Do I only need the ECU and TCU to make it run and shift properly? I see all these guys sell custom harness but I can get an OEM harness for $200 buxs. If I can make the OEM harness work with out a lot of modification I can save myself $500 +

I was very happy with the parts, easy to install and really liked the result. http://www.youtube.com/watch?v=7ZA4euk6R0U Plynouth VIP '67 TT IC EFI
