Hi all, I have a comp cams 305H that’s for a small block mopar., flat tappet hydraulic. 305 duration and 525 lift. Specs here, https://www.compcams.com/magnum-253-253-hydraulic-flat-cam-for-chrysler-273-360.html This is a take out from my sons 360 that’s getting a stroker kit, aluminum heads and such along with a new roller cam. Looks nice and clean with very little usage. Here is a video of the car running that cam. https://youtu.be/qHq5tcuQLcM Free, you cover shipping. Send a zip code for a shipping price. Cliff Ramsdell
