Ive just picked up a fully stock sbc400 for $200.00 and going to put it in the car. It needs cleaned up but beyond that everything looks really good. The cylinder walls are nice and smooth and dont appear to be scraped up at all. Im looking to make a mild street engine. Im looking at $1000-$1500 to put into this. Does anyone have any tips or tricks to make the 400 run good. Im very new with all this and this will be my first v8 swap. Ive delt with 4cylinder motors before but i realized that american muscle is the way to go.
