F-100 / F-150 LS swap

A typical F-100 / F-150 LS swap runs about $12,000–$20,000 in parts ($8,000 on a budget), and the big decision is where the engine sits: the front suspension picks the mount, since QA1 and Crown Vic clips each have their own.

Mounts & swap kits
4 options · $113.95Why you need it: The mounts set where the engine sits, and that decides oil pan, header and driveline fit. The front suspension picks the mount: QA1 and Crown Vic clips each have their own. On a stock chassis the CPP brackets set the engine 1/2 in back, which helps the pan clear the crossmember. More: engine mounts and swap kits.

Oil pan
3 options · $265.99Why you need it: The pan has to clear the crossmember, the ground and, on a 4x4, the front differential. Holley's 302-2 gives the most room where the steering linkage sits behind the engine crossmember (not for LS7 or strokes over 3.62 in). More: oil pan guide.

Steering
2 options · $1,168.99Why you need it: The engine and headers have to clear the steering shaft and box, and some swaps need a new shaft or box to make room. On 1965-79 trucks CPP's Mustang II kit with a power rack bolts on with no welding; on a stock front end, plan a U-jointed shaft around the header. More: steering shaft and box clearance.

Brakes & booster
2 optionsWhy you need it: A big cam can leave too little vacuum for the booster, and some swaps leave no room for one. A hydraulic brake assist that runs off the power steering pump fits where low vacuum or a tight firewall rules out a booster; 1965-79 Mustang II kits add 11-3/4 in front discs. More: vacuum booster or hydroboost?

Transmission adapter & clutch
3 options · $471.99Why you need it: An LS needs its own bellhousing or adapter and the right flexplate or flywheel, and an electronic transmission needs a computer to shift it. A GM 4L60E, 4L80E or T56 needs no adapter; keeping a Ford manual (T5, T-3550, TR-3650 or TKO) takes an LS-to-Ford bellhousing. More: transmission guide.

Accessory drive
3 optionsWhy you need it: The balancer, water pump, brackets and pulleys must all be one spacing, or the belt won't line up. Brackets have to clear the F-100 frame rails and steering box, so relocation brackets or a mid-mount drive are the usual answer. More: accessory drive guide.

Cooling
2 options · $675.99Why you need it: LS water pumps put both hoses on the passenger side and the engine needs a steam line, so the radiator needs LS-style ports or an adapter. No direct-fit F-100 LS radiator exists: universal double-pass units need brackets and hose work. More: radiator, fans and steam line.
