Easy firewall mod, just loose some interior space. no big deal. I used a half a garden wheelbarrow for the round corners versus a square box.
It can be done with a filter relocation kit, cutting the lower section on the firewall, vega steering box, and a set of tight tuck headers. Good luck.
Here's mine I pused the enging back into the fire wall to make room for the blower drive. it fits and runs great.
I squeezed a 289 into my 31 roadster by trimming only a couple of inches from the center part of the firewall.
I'm using a 289 in my '29.Sits about 3 inches behind the firewall. Due to its length,the stock oil filter causes clearance issues on the left frame rail.Swap it for a Motorcraft EFL90 or equivalent as it's only 3 1/2 inches long.
