I need help deciding here on how to build engine. I am planning on 12 mm studs with cometic headgasket. I have a 160 horse p-pump. Thinking of 4k gov kit, #5 plate, 181 delivery valves. Maybe rackplug. For sticks dynomite diesel 90 hp injs or Ind Inj 100 hp dragon flys. How are the 435's new era diesel has, they comparable? For a turbo, i was thinking a super phatshaft 62 or HTB2 62. I am lookin for 500 - 600 hp. I am installing 60lbs springs and heavy duty retainers. Any suggestion for timing?? I need to figure this out so i can tell Dave Goerend what i am using so he can build my torque convertor. I want the combo to be streetable without smoken out the freeway. Any advise or suggestions is greatly appreciated. :thankyou2:
