1971 Chevelle 350 Mild Motor Build

Hey guy, First post of many here, looks like theres a great group of guys here!

Car - 1971 chevelle malibu - in 1234325 pieces motor is first up on the resto.

All orig. 350, 3 speed auto

Question is, have already purchased street avenger 670 holly, edelbrock performer carb, headman headers(short ones if that matters).

I have a comp cam, xtreme energy cl12-242-2 dur 268/280 lift .477/.480

question is when I bolt these parts on, whats involved with putting the cam in the stocker motor? and suggestions on valves? (can i use z28 springs like one guy said might be a possibility?)

Can is going to be driven often and money supply is basically as budget as can be.

What would you guys do? Should I find another cam or can i use this one with matched lifters that are all brand new.

Anything helps! Thanks!

My first thought would be to do the motor last,it sounds like your Chevelle is in many peices,and a full resto is in the works.If the motor sits too long,the assembly lube on the cam could drip off,and this could lead to cam lobe failure upon breakin.Also,use the proper springs as recommended by the cam manufacturer,not ones that someone else think may work.The specs on that cam look to pretty good for a semi-mild street car.You need some more info,what heads,compression ratio,what are your goals,etc.A well thought out & built combo will make you much happier than a mismatch of parts.Proper machine work will give you a good start,bore & plate hone,align hone,block decked,balance the rotating assembly,etc...

buy the springs that work with the cam, one of the biggest mistakes people make is using the wrong valve spring...
