I can lighten the pistons,( my shop). I'm considering Lunati Voodoo cam/lifters, 1,800-6,400 rpm range. Light car, lot's of gearing, 26" tire and long tube 1 5/8" primaries w. 3" collector headers. X pipe, if it will fit. I'm also considering a pair of 48mm Webber IDF's, on the 4bbl manifold. Anyone have experience, with similar set-up ? Thanks, ateam.
