Been in a big debate for a long time of what engine to use for my 65 chevelle build. I want to run a Procharger D1SC on the street running pump gas, I am guessing running it at 7 pounds of boost.

But I do not have a base engine to start with. So I wanted to get some recommendations of what you guys would suggest to start with? LS3 525 crate engine, LSX B-8, or sink the same amount of $$$ into a iron truck block?

The goals with the car are to be able to drive it every day with out problem and hopefully get around 650-700 HP at the crank.

So what do you guys think? Am I on the track with these three options? Which one will best provide good reliable power and not end up being a trailer queen but a daily driver?

WTF is a LSX B-8?

Definitely iron block over the other 2. a K-1 rotating assembly will most likely to do the trick for your needs. Tried to stick to a CR of 9 – 9.5:1 on pump gas.

Its' a good idea to have a little extra room to turn up the boost once you get use to the power.

You could meet or exceed your goal with any of the three options. That said:

A) Do you care about the weight of your engine?

B) Will you decide you want to turn up the boost a lot and make 1000 hp and weight means nothing?

C) Do you want a light motor capable of making 1000 hp?

A = LS3 (I'm making 850 at the crank with this block)

B = LSX (Limitless but heavy)

C = Resleeved Aluminum Block (Better sleeves best of both worlds)
