Genocide,
Thanks for the question and gathering some great answers your making it easier for me. I have my 250 out, ready to be rebuilt and I was looking for ways to add power. Just two questions for all;
Will I notice a big difference in power if I add a 4 barrel, intake, headers and keep the internals stock?
Will changing any of the internals as well make a big enough difference?
I am driving a 69 chevy truck, adding a T5 trans and the rear end is a stock posi-track, but I don't know the ratio.
Looking for ideas before the engine is torn down snd how much it will cost.
And it will be a daily driver that will be pulling a boat, hopefully a lot!
