Hi Jim. Interesting comments. Also planning the same T56 Magnum. Not the XL. Obviously I have no way to know what will happen with mine until I get to that point. Probably some months (at least) depending on timing for the engine and which Coyote I end up using. I'm surprised about the fitment issues you're describing, as the 302/351/T56 combination is listed on the Gen 3 order sheet, so would seem it's a supported configuration. Without cutting and welding metal. Was there every any discussion with Factory Five about it? The three Gen 3 builds (that I know about anyway) from Factory Five were all Coyote builds, and at least one with the T56. So I'm hoping this is not an issue for my build. I do know for certain that a Coyote is shorter than the 302/351 block, at least in relation to where it sits. For the Roadster, they supply an adapter plate because the transmission mount doesn't reach the standard mounting location on the transmission A-frame. I just did a side-by-side comparison of my #7750 build (302 DART block) and #8674 (Coyote), both with TKO's. The transmission is 1-1/2 to 2 inches forward with the Coyote compared to the SBF. I will be fitting the engine/trans early in this build, before panels are permanently mounted, wiring/brake/fuel run, etc.
Thanks for the correction on the wheelbase. 96 was the number in my mind, so didn't look it up. Thanks for pointing it out. I fixed my post.
