Beefing Up A 1971 Chevy C20 402

[WadeChris]

Hey Guys,

I have been using this site nonstop since I started my frame off restoration of my old HS 1971 Chevy C20 Custom. Body wise I am doing ok and have found countless threads to help me out when I get stuck. However, I am completely in the dark with the BB 402!

I am looking to turn the truck into a badass flatbed, truck came with the HD coil springs and the additional split leaf springs. It also has the Manual 4 speed (granny gear) SM465. The truck is a beast and was running well when I started the resto.

How can I beef up my 402 cheaply and effectively? I figured new headers, intake manifold and cam? I hear that the quadrajets aren't too shabby and I don't have the funds to start getting into the pistons and such.

Thanks so much gentlemen!

I just got my truck back from getting some motor work. Put in a Comp magnum 270 cam new intake, carb and headers. Went with headman mid length headers, my mechanic wanted to Change to a Holley carb and a different intake. I like the way it runs and sounds now using dynomax mufflers. I have my old intake and carb for sale if you're interested, they were on the truck for 3500 miles. Edilbrock preformed 2.0 intake and edilbrock carb. They are listed in the FS section.
