Ford Crossflow straight 6 engines with carburettor, 250ci, 4.1 litre.

Kustom Bitz has done it again, we must be crazy, like who else would bother producing a tough sounding camshaft for the X-Flow engine to complement our ever popular AussieSpeed 4 barrel manifolds, but we love sixes too.

KustomBitz Hot Rod Cams will give your crossflow that rumpity, rump, tough sounding idle that will turn heads and have them thinking is that a six? It sounds too good to be 6 cylinders. You will have a cool look on your face like you didn’t notice them and thinking .... 'yeah it goes good too and I don’t have to rev its tits off' .......

Our lobe profile is kind to your valve train because of it’s modest lift and duration figures. However both Stage 1 & Stage 2 cams start producing torque at 1500rpm and produce exciting torque around the 2500 - 3300rpm depending on your other engine mods.

Stage 1 cam’s torque band is strongest from 1500rpm to 4200rpm and can be used with stock stall converters for automatic transmissions.
Stage 2 cam’s torque band is strongest from 1800rpm to 4800rpm, and we recommend using 1800-2200rpm stall converter in most cases, and higher compression and free flowing headers and exhaust.

Both cams work well with a manual transmission and have reasonable vacuum to operate your power brakes.

Forget using the stock EFI computer on later sixes, the OEM fuel delivery settings will just not cut it. You would need a programmable unit to run EFI.

Final drive diff ratios
Diff gears in the 3:1 to 3.25:1 range will feel better under your right foot with the Stage 1 Hot Rod Cam. And for autos with a standard converter stick with the Stage 1 Hot Rod Cam. Even if you intend running an 1800rpm hi-stall converter with the tall diff gears it is still better to stick with the Stage 1 because you only have six cylinders and relatively small cubic inches.

Stage 2 cams work real well with final drive ratios of 3.5:1 and 3.7:1 gearing and with the straight six it needs an 1800-2200rpm stall converter so it does not bog down in that initial off idle squirt on the accelerator pedal. Mainly so it spins easily through that 1000 to 1200rpm range with out loading up the engine. Remember a V8 is a little more forgiving for bigger cams at low rpm so be mindful of how you want the car to behave when you select the cam.

If you want a street screamer then you need one of our Street and Strip grinds
