Q: I own a 1971 Ford F-100 two-wheel drive pickup with a 360 engine.
The piston rings are worn and need to be changed. While the engine is out, I’m thinking of turning it into a 390. I’ve also heard it’s possible to make it a 410 with factory parts, and an Edelbrock Performer cam and intake package?
Turning your engine into a 410 is relatively simple, too.
You’ll need a 428 crankshaft like Scat’s cast crank, 390 piston, and your stock 360 rods. Factory 410s produced about 330 hp at the flywheel.
Expect an Edelbrock-equipped version to make 370-380 hp.
