Nova / Chevy II LS swap
A typical Nova / Chevy II LS swap runs about $8,000–$13,000 in parts ($4,500 on a budget), and the big decision is where the engine sits: the Hooker brackets set one position that fits only the Hooker crossmember and headers, and need 1972-up clamshell mounts bought separately.

Before you buy
- Mounts, crossmember & oil pan Well sourced
Decide where the engine sits (kit mounts or custom), then measure from the pan rail to the crossmember and to the ground before you choose an oil pan. - Transmission & driveline Well sourced
Decide which transmission handles your torque and how it will be controlled, then plan the crossmember, driveshaft length and flexplate or bellhousing to match. - Accessories & cooling Verify yourself
Decide one accessory drive spacing, and match the balancer, water pump and brackets to it. Then check fan, hose and hood clearance. - Exhaust Well sourced
Decide headers or manifolds that clear the steering, frame and starter where your mounts put the engine. - Fuel system Partly sourced
Decide return or returnless, and a pump and injectors sized for your power and fuel (gas or E85).

2Mounts, crossmember & oil panSet where the engine sits, then pick a pan that clears · 4 parts
- The 12618HKR brackets are designed to be used with stock OE clamshell-style engine mounts as installed on all 1972-81 Camaros, retrofitted into the swap vehicle with the kit's specially designed spacer plates; the clamshell mounts and long horizontal bolts are not included and must be purchased separately.
- The 302-2 is designed to use the GM F-body windage tray GM P/N 12558253, which must be modified (cut) to clear the pickup tube; a full-length tray may be used only if its front quarter is removed.
- Hooker 12627HKR is the 4L80/4L85 crossmember for 1st-gen F-body/3rd-gen X-body; it must be installed with the 12618HKR engine brackets, and then allows LS plus 4L80/4L85 installation without any cutting or hammering to the vehicle body.
Mounts & swap kits
4 options · $260–$281.95Why you need it: The mounts set where the engine sits, and that decides oil pan, header and driveline fit. The Hooker brackets set one position that fits only the Hooker crossmember and headers, and need 1972-up clamshell mounts bought separately. 1973-74 clamshell cars may need the holes redrilled. Sliders let you choose, then you set the driveline angle yourself. More: engine mounts and swap kits.

Oil pan
2 optionsWhy you need it: The pan has to clear the crossmember, the ground and, on a 4x4, the front differential. On 1968-74 Novas with Hooker 12618HKR brackets, Holley's 302-2 bolts in (3.62 in stroke max); Moroso's angled-sump steel pan fits 1968-78 and clears a 4.25 in stroke. More: oil pan guide.

Steering
1 option so far · $100Why 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.

Measure before you buy7 notes
- Holley 302-2 is the LS Gen 1 F-body retrofit oil pan designed specifically for 1967-69 Camaro/Firebird and 1968-74 Nova/Apollo/Omega/Ventura, and can also serve other chassis needing more engine-to-chassis clearance near the front half of the pan.
- The 12627HKR requires Hooker Blackheart 71223029HKR (black) or 71223030HKR (red) polyurethane transmission mounts, or an Anchor Industries 2268 rubber mount — all 1-3/4 inches tall.
- Using a non-Hooker transmission crossmember or headers with the Hooker system will adversely affect installation ease, component clearance, ground clearance, and engine inclination angle.
- The Hooker crossmembers include a maximized ground-clearance pathway for routing 2.5-inch or 3-inch exhaust tubing.
- The Holley 302-2 LS swap oil pan has a depth of 5.46 in.
- The Holley 302-3BK adds more front-sump clearance than the 302-2 and fits 1955-1987 GM muscle cars/trucks plus Ford Fox-body chassis.
- The Hooker 70101508-1HKR LS swap headers fit 1967-1969 GM F-body and 1968-1974 GM X-body cars and tuck closely to maximize ground clearance in lowered cars.
Kit-specific notes11 notes

Transmission adapter & clutch
2 optionsWhy 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. On a 1968-74 Nova an LS-pattern 4L60E, 4L65E or 4L70E bolts straight up with no adapter. More: transmission guide.

Crossmember
2 options · $449.95Why you need it: The transmission mount usually moves, and the crossmember sets the driveline angle. Hooker's 12625HKR fits 1968-74 Novas on the stock subframe; a TH350, 700R4 or Powerglide needs its 12628HKR adapter mount. More: getting driveline angles right.

Driveshaft
2 optionsWhy you need it: A different transmission is almost always a different length, so plan on a custom-length driveshaft. Sliding the stock crossmember back 3.5-4 in shortens the shaft by the same amount; Hooker 12618HKR brackets with the 12625HKR keep the stock Nova shaft. More: driveshaft length and angles.

- Because of their considerably lower transmission tunnel height, 1968-74 X-body cars require tunnel modifications to install either a TREMEC LS F-body/GTO T56 or a T56 Magnum with the Hooker system.

Accessory drive
2 optionsWhy you need it: The balancer, water pump, brackets and pulleys must all be one spacing, or the belt won't line up. A 1998-2002 F-body LS1 drive is the usual Nova pick; a GTO alternator has to become an F-body unit to clear the pitman arm. More: accessory drive guide.

2 options · $150Why 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.

1 option so farWhy you need it: Where the compressor mounts (high or low) can decide frame, fender and header clearance, so pick it before you buy brackets. Hooker 12618HKR mounts won't take the stock low-mount compressor, so a Nova needs an upper-mount A/C bracket. More: accessory drive guide.
