what I do for a blower manifold(I use eaton blowers-great performance and price)is I machine a 4bbl manifold(others can be used) flat(parallel to the crank line),machine up an aluminium plate(12-20mm thick) to suit and bolt on with countersunk bolts.blow off valves can be purchaced for minimal cost(although I've never felt I needed to use them-but I do have one installed on my blown 265 hemi 6)I mount the blower on parallel with the block and make the rest up myself.works well-have a go doing it yourself,as there is minimal machining required and cost is kept low.
