Seeking Insight on Pricing

I’m trying to get a sense of the market value for a 350 cubic inch Chevy small-block engine, specifically those with a 4-bolt main design. As someone who’s considering purchasing one of these blocks, I’d love to hear from anyone who has experience buying, selling, or refurbishing them.

Factors to Consider

Here are a few aspects I’m curious about that might influence the price:

  • Condition of the Block: How do scratches, rust, or other damages affect value?
  • Mileage: Does lower mileage significantly increase the price, or are there other factors at play?
  • Modifications: If the block has been modified (like bored over), does it add to or detract from its worth?
  • Complete vs. Partial: Is a full engine with accessories worth much more than just the block alone?

Market Trends

From the limited research I’ve done, it seems like the prices can vary widely based on these factors. I’d appreciate anyone sharing their experiences, sales they’ve seen, or any resources that could help me gauge what I should expect to pay.

Are there particular online marketplaces or forums where these transactions typically happen? I want to ensure I’m paying a fair price, whether I’m looking to buy or sell.

Conclusion

Thanks in advance for any advice you can offer! I’m keen to learn more about this segment in the automotive community and understand the demand for these 4-bolt main blocks.

I’ve been tracking 350 4 bolt main blocks for a while. Prices vary widely, but you can expect to see them listed between $300 to $800 depending on condition.

That sounds about right! Don’t forget the mileage and whether it’s been rebuilt or not. A low mileage block in good condition can fetch a premium.

Could you explain what exactly makes a block worth more? I assume things like originality play a part?

Definitely! Production year and whether it’s a factory part add value, especially for collectors. Also, a documented rebuild history can increase buyer confidence.

That’s super helpful! What about aftermarket blocks? Do they hold any value?

7

Aftermarket blocks can be worth anywhere from $500 to $1000, but it depends heavily on brand and specs. They are seen as less desirable than genuine ones.

Interesting point! Is there a specific year that’s considered the best for 350 4 bolt mains?

The mid-70s blocks are often sought after due to their durability. But remember, personal preference can play a big role depending on your project’s needs.

I once got a deal at a swap meet! It’s all about luck and timing. A bit of haggling never hurts either!

True! Just be ready to walk away if the price isn’t right. It’s a buyer’s market right now.

I’ve seen 350 4 bolt main blocks range from $500 to $1500 depending on condition. They are known for their strength, which makes them desirable for builds. Worth investigating with local sellers!

That’s true, but I think you need to consider how they stack up against other blocks like the LS series in terms of performance. The 350 is great but the LS offers better efficiency.

16

I agree with you, flin. Performance-wise, the 350 4 bolt is reliable, but it can’t match the horsepower potential of modern blocks. Longevity is good too, but a lot depends on maintenance and build quality.

17

Exactly! But let’s not forget that 350 blocks can be built to produce fantastic power, especially in classic car restorations.

18

I think it’s also about the nostalgia factor. A 350 in an older vehicle really captures that classic feel, whereas new engines might lack that character. This can increase their value to collectors.

19

That’s a good point! A lot of enthusiasts are willing to pay a premium for that nostalgia, which can skew market value upwards.
