[67 chevelle]

Thanks brother , that link is for small block headers , ill try and snap a picture tomorrow , by the way neither side fitts ,and all ls are the same , are you running electric fans ?

I am running an 08 ly6 out of a silverado , with the stock mechanical fan up front , so that 3 inch forward would not have worked for me , doubt it will help with the manifold fitment either , probably make it worst , , i had to slot the holes in my trany crosmember towards the rear about 3/8 to 1/2 inch

If you are moving your engine forward you are going to have to get a long yoke or driveshaft work
