    Hotrodding Basics
    Okay I am building a 400 sbc for my nova. Big upgrade from the 307. I have a stock 400 am swapping in a 488/510 hyd flat tappet. 750 quadrajet edelbrock rpm or airgap intake(don't kno which one) and keeping the powerglide(rebuilt) with 2.73 gears. Can anyone make a good guess to how much...
