I have a stock 350 with a edelbrock performer manifold and a 600cfm carb. Would it be worth it to stroke and make into a 383 and a bigger cam but keep stock heads. Or would it be better to keep the block the same and put a bigger cam and better new heads? Im tight on money and would like to know if doing all that block work would be worth the money instead of buying new heads.

smallblocks need heads...get them first.

You'll have to provide a little more info for an accurate response. What is your intended use, HP goal, and what head castings do you have now? Does your engine have flat top pistons, or dished? 400 HP out of some stock head castings isn't too hard, and if you're looking for torque, they are more than adequate. It all depends on what you are looking for. Cubic inches and good flowing heads are the foundation to building power providing you match your parts accordingly. If you go the 383 route, and cash is you limitation, you can always upgrade the heads later on.

I want to be at about 400-420hp. Im going to be getting a 800cfm holley dp and a hydraulic cam. I dont know about flat topped or dished, and i cant find the casting number on the heads i know there stock for a 350 malibu(275hp).

If your choices for carbs are the 600 and the 800dp, definately stick with the 600. The 800dp will take a bit of tuning and will likely be a bit of a slug on a modest 350.

I agree with the others above, good heads are the key. I'd start by looking there. A 350, even a low compression one, will run pretty good with a set of decent heads and a performer rpm, and a 650 carb. Choose your cam based on the rest of the combo.

my car was dynoed at 325hp and 385 tq, around how much would a new pair of good heads and a bigger cam put me at.
