This is a brief forum post starting a project journal for swapping a Ford 302/5.0 V8 into a 1976 Triumph TR7 that currently runs its stock 2.0 engine. The owner outlines the planned engine build using mixed Mustang parts and a modest power target, but the thread contains very little further detail or progress update.

How it was done
Starting point
The TR7 currently runs its original stock 2.0 litre engine, producing modest power. The owner opened this thread in the Triumph section of the forum to document and discuss the planned V8 swap with other builders.
The planned engine
A Ford 302 (5.0) V8 is ready to go into the car, built from a combination of stock parts sourced from an 85 and an 89 Mustang GT. The owner describes this as a budget-minded approach rather than a full high-performance build.
Induction plan
The engine is to be fitted with an Edelbrock intake manifold and a Holley 550 cfm carburetor, chosen to keep the build on the less expensive side while still giving a solid power gain.
Power expectations
The owner expects roughly 200 horsepower from this combination, about double what the stock 2.0 engine currently produces, with the option to increase output later if he wants more.

Worth knowing
- Building the V8 from mixed Mustang donor parts can keep the swap affordable.
- Starting with a modest power target leaves room to increase output later if desired.
- Choosing a common intake and carb combination simplifies parts sourcing for a budget build.
