MAX OUTPUT Drop in Valve Spring Kit, for 3/8" Valves

Application: FE FORD, 352, 360, 390, 410, 427 & 428 With Hydraulic Flat Tappet and select mechanical flat tappet cams.

Our Drop in FE Ford valve spring kits are intended for heads w/ a stepped spring base which just so happens to be the most common version out there.

Alex's Parts offers several drop in kits for FE Ford; three or four cylindrical kits and a few beehive versions.

This version here is for the "Max Output I" variation.

This Max Output I valve spring kit is normally used on cams with up to around 236 degrees duration at .050" and up to .570" lift.

If you need springs for a bigger cam, take a look at our Max Output II versions including our beehive kits.
