60lb exhaust springs
#12
i asked because i will be running 4k, for now...till i get my pump redone, within the next month my bottom end will be studded and girdled. a fluid damper is on it's way. i work t an industrial diesel machine shop, so i have the benefit of not having to pay for machine work, or having the rotating assy. balanced. i was just wondering if it would be good to go for a heavier valve spring straight off rather then spend the money on the 60lb and then upgrade to a heavier spring

800hp for now, 1200hp some time down the road..... the truck is a project i am doing a 79 ford super cab 5.9l cummins etc, it's my dream truck and i finally have everything i need to get it done. so as far as the truck being down it's still in the process of being made, so i have a lot of time to get the engine right before it goes in the truck
