I did buy the blueprint 408. If you put all the parts down on a piece of paper and price them all out, stroker kit, rebuilt heads, intake. w/p, f/p, carb, MSD dist+wires and machine shop(especially here in Calif)your labor the price comes out to almost the same. I agree 100% to build it yourself and check it to make sure it is absolutely perfect. I was in the need for speed and while doing the rear end,front suspension and tranny, here came the crate engine. The problem I had was an oil leak at the rear seal area,which I had to pull the engine back out (that sucked)they paid the freight to send it back and forth and repair it. In a way it was good so I spent the time to paint the engine compartment (which I should have done the first time). I only complaints I have is the carb is way too lean-its a 1411 and I jetted it to the 3rd level of the 1407. The bypass hose is hokey going from magnum top-end to the old style water pump. I have almost 3k miles and so-far so good.
