76 350 sb need help

i have a 76 350 sb stock and was wondering how i could determine what i need to the horsepwer i want. say if it already
pulls 300hp and i want to take it to 375hp or higher how would
determine what i you can tell ive never built an engine before but have allways wanted to and now have the opprotunity
so any links to a web site that may offer some step by step to overstock engines would help. if there is such a thing.any help in genrel would be appriciated nice to meet every one and thx.

p.s.have nothing to put this motor in yet but have a few choices
figure i would build the motor first then go from there.

There are so many different possibilities that you'll have a hard time getting anyone to respond to this question. There's just too many answers.

Here's a suggestion or two. Look around online for people selling 'crate 350 engines' then find a few that are in the HP range you want. Write down what they list for upgrades and mods to the engine. After you dig around a little while you'll get a pretty good idea of what mods you'll need to get wherever it is you're aiming for.

Some companies like Edelbrock list engine setups that they built - using all their own parts of course- that show many different HP and performance ranges. You can always check out their stuff and get the specs for what they did, and then shop around.

Once you've got a pretty good picture in mind, if you come back and dig around the site you'll usually find someone has already asked if Brand X's cam is better than Brand Y, etc... The old posts can give you a good street-side opinion of the advantages/disadvantages of certain parts and combos.

There's also an author named David Vizard who has written some excellent books on modifying Chevy Small Blocks. I found a copy of one on building short blocks on a budget in my local library to borrow.

If you plan on building the 76 small block, your best bet is to find a better set of heads. The miid to late 70s heads don't flow very well, especially if you want to put a bigger cam etc in it.
Just my 2 cents

First, what are you putting the motor in and what are you wanting it to do? That will help you decide what you need to do to the motor. I have a '75 350 sbc that I am putting into my 31 chevy roadster pickup. I have mine bored .060 over, newer crate motor heads, a wiend stealth aluminum intake, and a 600 cfm edelbrock carb. That is plenty of power for me. Changing your cam, intake, and carb are going to be your easiest upgrades.

those are great starting points.i have to say i really appriciate
it.though i have seen that book short blocks on a budget thought about getting it but didnt know if it would be worth the money
or the content would be over my head.i was going to ask about it in my first post but forgot about it.again thx everyone.

how much money do you have to spend?
What kind of tools do you have? Do you have a library of how to build engine books? do you have a GOOD engine stand? Do you have a place outside, not in a basement to build your motor? Do you have anyone to help and learn build? Double check every move you make. Like when you build something and they say measure twice, you need to double check what you are doing. I would like to say I taught myself but I didn't , my father taught me the basics and I have grown from there. Good luck and I know we will be hearing a LOT from YOU! OH YEA, ask questions even if you think you know what you are supposed to do, it will save you $$$$$ and headache's.
