budget 350 build

or not so much going with the 305 h.o. heads, but is it possible i could just shave the stock 350 heads how much should i shave off of the stock 350 heads to work with flat top 4vr pistons and get 9-1 or 9-5 c/r?? i was reading in some forums that by using flat tops with 58cc heads would average over 10-1 if not 11-1 , but by using special pistons would lower c/r. which would be my best bet?

Stop!

Why do you keep asking these questions and not paying attention to any answers? Why oh why would you want to use 305 heads?!

What 350 heads do you have now? What size combustion chambers do they have. 64 cc chambers will yield approximately 9.5:1 with flat tops.

Isn't that a single plane manifold you listed? No bottom end torque! You need a dual plane, especially in a truck!

How many more posts are you gonna put up here without doing any research on your own? How many more replies to your posts are you going to ignore? Nobody minds helping people on this board, but the person asking the questions needs to be serious about wanting input from the other board members!

I had a 355 with flat top dual valve releif pistons and 64cc chambers, the builder said it was right at 9.98:1. With a set of 58cc heads on this combo, you would be around 10.5:1. That is not considering the fact that the heads have been milled. That motor will probably not run on anything under 100 octane.

budget 350 build

thak you for you input on the 305 heads, i guess it was kinda dumb to kinda want to interchange.All it would do is work against every aspect of this build.
when you say reserch as in what all the different components do and act with each other? example for it, a 50 state street legal camshaft will not work with a high rise manifold. it`ll cause hesitation and prolly won`t idle? things of that sort. or am i looking at an engine build at all the wrong directions?

What he's saying is that you've essentially asked this same question before. Go back and read his advice from this thread you posted about a week ago and read his post again. He suggested you read some of the tech articles from a few magazines that are online. That's how you will begin to learn which parts work together to make power and which wont. You can throw just about any old SBC part on a 350 and make it run, but how well it performs is a different story.

I think you need to look at the GM Performance parts engines and pick one of them. They've done most of the choosing for you and you can get a good engine that makes good power and even has a warranty...

sorry about the confusion.

it`s just i had been told that an engine was built for mudracing using 305 heads with an edelbrock cam and it ran pretty good.so i tried to increase the cam and intake. i guess i have receive some big time Bull-shat advise, and suggestions. but i`ve already posted in one of the other threads about the 380hp, 420lbs torque build . i`m just gonna copy someone`s build or try anyhow.without closing the bank.

If you're on a budget and you choose to use factory heads then the only way to go is the Vortecs, they are far better than the 305 heads...
