So what is the benifit of changing the pump? Just changing the spring will increase your pressure. And as mentioned earlier in the thread, shimming the spring will continue to increase the pressure.
The Fueling pump will flow more oil or I should say it has a larger flow rate. The Basiley spring will give us more constent pressure to the lifters to keep them pumped up but for cooling and lube the fueling pump with it's higher flow rate will do the job better than the stock pump. I used the fueling pump in the strokers I build but I must say it still has 0 to 2 lbs at hot idle....when I install the Basiley spring with the fueling pump the hot idlewent up to 15 to 18 lbs. I think its a good combo but, the spring is my first choice.
