Xm270hr cam questions
I am going to start building a 358 with vortec heads and i wanna use the comp xm270hr cam. I have stock manifolds with 3 inch plates and stock risers .and side exit throuh hull thats 4 inch all the way. Has anyone had any reversion problems with this cam . I belive the 3 inch riser plates will help immensely to prevent it . Comp says i shouldn't have an issue . Looking for input

I run a x4270hr in my 350mag no problems!
The xm270hr has to much lift for a stock Vortec head
shock vortec head has a .474 max lift Otherwise you’ll hit your valves Seat
