Bare with me this is my first post. I have a stock 350 that I want to build. We got it from a family member who has multiple sitting in his shed. But we want to run the comp magnum 292 cam in it. We are going to match it with 64cc 200cc Heads. On top of that we are going to run a performer rpm intake with 650cc Edelbrock carb. We will also be running a 3000 stall with 4.10 posi.
My question is will this setup work well or end up being a dog? I am hoping 400hp. Any help will be greatly appreciated. Thanks in advance.

The engine will be going into a 83 c10. It has 700r4 transmission with a shift kit. The build is going to be for drag racing and maybe some trips to the drift pit. So what I’m hearing is definitely a bigger carb and a new intake woud be a necessity.

If you seriously want to drift a pick up??? You need some torque at a lower rpm.

I would start with a minimum of a 540, turbo 400,3.9 to 4.1 gears

tune the engine to make peak power 5500 rpm or lower.
600 pounds torque of more.
drifting is more than slipping in corners, you want to blaze the tires

With that being said any recommendations on how to build a 350 that would be sufficient for that?

If you plan to drag race?
DETERMINE:
how fast you want to go
how much your truck weighs
How many horses you require


after that draft engine plan

For drag racing I would like to run around high 12 low 13s. Not planning on a 10sec truck. The truck weighs 4000lbs currently. I will be gutting bed and some other misc items to cut it to 3500 eventually.

A Supercharger or turbo is being planned for the future. But will be down the road in next year or so.

I’ve been doing some research. And it seems I could have decent build with a XE274 cam and 64cc chamber 180cc heads. Along with a 2500 stall and 4.10 gears.
Just wondering what you guys think about this. Just to get me going for now. Then once I go forced induction I can swap to bigger heads to lower my compression.

I currently do have the truck already. And I’m 19.It has a Edelbrock 650 carb on it. Along with performer rpm intake.
And I have worked with engines. We built the 305 that’s in it now and put it in. And I’ve done engine work on my civic also. But the 305 has its limits which is why we are going with a 350. I’m currently about 1000 miles away from the engine at some training so I’m not sure what the stock build consists of.
I was hoping to swap over the headers, intake(performer rpm), and Edelbrock carb.
I’m looking for something powerful enough to get me going until I can afford the supercharger. So I’m open to recommendations.

 

[A.J. DeRousse]

I have considered boosting the 305. The only thing is we have a 10.5.1 compression. Which is way to high for boost. So I’d have to lower it to at least 9:0:1 or 8:5:1 preferably

 

[A.J. DeRousse]

Very true I didn’t even think about that. I’m sure he does have at least 1 decent set of heads I can use. Now I did reading that a blow through carb would be needed. But also read that if not going over 8psi that wouldn’t be necessary? Tell me if I’m wrong though. Or if I used a carb enclosure I could stick with the stock carb?

So from the recommendations I’m going to turbo the 305 with the heads off a 350 to lower the compression. And once we get that together this summer hopefully. We are going to start building the 350 for turbo in the fall to be ready by next summer.
