its time for me a rebuild, i have no oil pressure. im looking for just a cheap reliable freshen up kit till i build a stroker in the next year or two. i was interested in one of these kits, SUM-CSUM306KIT or FEM-MHP173-300 from summit but i coulnt find any info on them. has anyone ever used one of these kits? i have a 500-510 lift lunati cam, headers, exhaust, 110 fuel pump, adjustible fuel pressure regulator set at 45, 1.6 rollor rockers, trickflow valvesprings, 70mm throtlebody, stock heads and intake. with the rebuild i wanna get the gtp heads off an explorer with the gt 40 intake. is this a good idea or should i go with a diff route?
