I had a T reg Mk3 1.6 GL Capri, that ended up as a 2.1 with a 270 deg cam.
Never got as far as twin 40 Webbers, I think it had the 38 DGAS from a 3.0 Capri. I got sick of changing gearboxes in the thing, but by heck could it accelerate (in a straight line).
I got rid shortly after an embarrassing episode at the lights in town one Friday night…
After revving the engine for the de-rigour drag race, I dropped the clutch only for the car to lurch forward & stall literally in the middle of the lights. After bringing rush hour Lichfield to a standstill I discovered the rusty front seat mounts had finally given way, tipping me backwards into the boot, (rear seat removed for weight saving, obviously). Embarrassingly I had become stuck, my shell suit bottoms snagged on the fake roll cage upright, constructed from a scaffolding pole.
After finally freeing myself I had to tip the seat out of the drivers door & crawl out onto the road in front of hysterical drivers.
Things went from bad to worse when I bought an XR3i.
