Power is money sir. What is your budget?
If you don't have GM L31 Vortec heads, this is a great addition for low bucks. You may already have them if yours is a truck motor. You will want to change the cam in the rebuild anyway. So if you are willing to spring $450 for the heads, $200 for the intake and $150 for rocker arms on top of the rebuild cost, you can have 325hp motor pretty easily. Spend another $300 for a stroker crank and you could be in the high 350 to 380 hp range with a top tune.

MY BUDGET IS ABOUT $800. BUT THIS IS FOR EVERTHING FROM BATTERY TO U-JOINTS AND FROM AIR CLEANER TO MOTOR MOUNTS. I HAVE THE HEADS FOR THE H.O. 305 THE ARE IN GREAT SHAPEAND HAVE BIG VALVES. THE HEADS THA CAME ON THE 350 ARE NOT A NUMBER MATCHING SET AND LOOK VERY BAD VALVES SET LOW IN THIER SEATS.

those 305 heads will bump your compression and if you are willing to live with 5000rpms they will be good,match the ports to gaskets and clean up the pockets a bit,get some chevy brown valve springs(about 55bucks a set).these heads have 184in intakes and ports slightly smaller than stock 350, the combustion chambers should be around 60cc. these heads will build low end torque and will probably max out around 5 grand,the small chambers will give higher compression so watch your duration when picking your cam.when picking your cam keep these things in mind... power from idle to 5000,full duration around 262,moderate lift(440 to 460)and use small dia headders,500 to 600 cfm carb(smaller the better

Rebuild the short block stock w/ high vol oil pump & moly rings. Have a 3 angle valve job done on the 305 heads w/ springs to match the cam and new seals.Select a mild cam.I had this motor w/ a cam 280/290dur 214/224dur @ 050 .443/.465lift 112sep. This motor run like a raped ape!!
Toms right keep it to 5000rpm.Also your stock intake & carb should work fine to 5000rpm.Get 1 5/8" headers.

I'd have to agree with 78 monte except for the oil pump. A high volume oil pump actually drains quite a bit more power than a stock oil pump. And not to mention, they are not even necessary unless you are regularly turning above 6000rpms.

I recommend the edelbrock performer package. Intake #3701@$141.00, camshaft #3702 @ $123.99. 1 and 5/8 inch tube headers about $200.00 and their performer 600 cfm carb @$181.00. This group is a recommended street/strip combo for sbc. There's a lot of research money invested in this combo, and the price is right. Best of all, THEY MATCH. You wont have too much of one thing and not enough of another. Much better than a shot in the dark. I plan to go this route on a future build up. Good Luck and the prices are JEGS as of today.
