Small Block Chevy Crate Engine for Sale: Where to Buy 327, 350, 383 and 400

Small-block Chevy covers more ground than any other single platform in the crate engines category: 327, 350, 383 stroker, and 400, from multiple builders, at wildly different price and power points.

This guide covers where to buy a small block Chevy crate engine for sale across all four displacements, what actually separates them, and a couple of spec discrepancies we found between what’s listed here and what the builders themselves publish, worth knowing before you order.

Small Block Chevy Crate Engine for Sale: What’s in Stock, by Displacement

Four small block Chevy crate motor displacements are in stock here: 327, 350, 383 (stroker), and 400. Each comes from one or more builders, so the same displacement can show up at very different price and horsepower points depending on who built it. Every part number below is in stock right now, not a discontinued or special-order listing.

You can browse the full crate engines category and filter by price and stock status. For how Chevy compares to other brands, and how configuration drives price generally, our where to buy a crate engine hub guide and our Chevy crate engine guide (covering small-block, big-block and LS) both build toward this one.

350 vs 383 Crate Engine: Picking the Right One

This is the most common small block chevy crate motor decision, so it’s worth a straight answer.

350 is the most universally documented small-block displacement. Parts, knowledge and aftermarket support are everywhere, and it’s the safest default if you’re not chasing a specific power target.

383 is a stroker: the same basic architecture bored and stroked to more displacement, trading some of the 350’s simplicity for meaningfully more torque at a similar RPM range. If your build genuinely needs more than a 350 delivers, a 383 is usually a better answer than just adding more bolt-on parts to a 350.

327 and 400 sit at the two ends: 327 is the lighter-breathing, higher-revving classic option, and 400 is the largest-displacement small-block Chevy option, good for torque-focused builds that don’t need stroker-level work to get there.

If you’re building a C10 specifically, our best engine for a Chevy C10 guide covers which of these fits that platform’s typical use case.

Check Fit Before You Order

Small block Chevy displacements share a lot of common architecture, but dressed configuration, balance (internal vs. external), oil pan style and accessory drive still vary by builder and by part number.

Run the specific part number through the site’s own Compatibility Check tool before you order, even if you’ve bought a small-block Chevy before. “Small block” isn’t one spec.

Featured In-Stock Models

Four current listings illustrate the four displacements.

BluePrint GM 327 350 HP fully dressed (BP327CTFKV)

A fully dressed 327. A closely related BluePrint listing for this family (BP327CTFV, deluxe dressed, fuel injected) confirms the “deluxe dressed” designation but doesn’t publish a horsepower figure on its own page; BluePrint notes that a dyno printout ships with the engine.

Chevrolet Performance 350 base long block (19432780)

A factory-sealed base long block from GM’s own Chevrolet Performance division, covered in more depth in our Chevy crate engine guide.

BluePrint GM 400 508 HP base long block (BP4002CT1)

A base long block at the top of the small-block Chevy displacement range stocked here. See the discrepancy note below before you budget around the horsepower figure.

BluePrint GM 383 stroker, 436 HP (BP38318CT1)

A base stroker build illustrating the 383 option directly. See the displacement note below before assuming “383” is the exact figure.

Current pricing, exact included accessories and stock status are shown on each product page rather than reproduced here, since all four change over time.

A Couple of Spec Discrepancies Worth Knowing

Checking these part numbers against BluePrint’s own site turned up two mismatches worth flagging rather than quietly repeating.

The 400’s horsepower. UEP’s listing for BP4002CT1 states 508 HP.

BluePrint’s own official page for the identical part number states “500 Horsepower / 510 ft. lbs. Torque.”

An 8 hp gap either way is small in absolute terms, but confirm the current rating with BluePrint or UEP support before using it in a build sheet.

The 383’s actual displacement. UEP lists BP38318CT1 as 383 cubic inches.

BluePrint’s own knowledge base for this series states the bore and stroke “mathematically yields a 377ci,” and repeats 377 in its own notes, while only its meta description says “383 c.i.”

The horsepower and torque figures (436 hp / 443 lb-ft) match on both sides; it’s specifically the displacement label that’s inconsistent. If exact displacement matters for your build (a class rule, a specific stroker kit plan), confirm it directly before ordering.

Neither discrepancy is large, and neither changes which engine is right for which build. But a buyer quoting a customer build, or entering a class with a displacement limit, should confirm the live figure rather than trust either page blindly.

Warranty and Shipping, Briefly

BluePrint Engines coverage and Chevrolet Performance coverage differ from each other; our Chevy crate engine guide and the main where to buy a crate engine hub both cover the brand-by-brand terms in full, including a known disagreement between UEP’s stated BluePrint term and BluePrint’s own published term. Read either before assuming any two engines here are covered the same way.

Crate engines ship as palletized freight, with published US and Canada delivery windows of 7 to 14 business days, quoted at checkout based on weight and destination. Full steps are on the shipping information page.

Common Mistakes Buyers Make

• Assuming “350” or “383” means identical specs across every builder and part number.
• Budgeting around a horsepower figure without checking it against the manufacturer’s own current listing.
• Picking 383 by default without confirming a 350 genuinely falls short of the build’s needs.
• Skipping the compatibility check because “it’s just a small-block.”
• Not confirming internal vs. external balance before ordering flywheel, flexplate or balancer parts separately.

When to Get Help Before You Buy

If you’re deciding between 350 and 383, or unsure which small-block displacement actually fits your build goal, it’s worth asking first.

Small-Block Chevy Crate Engine: FAQs

Where can I find a small block Chevy crate engine for sale online?

Universal Engine Parts lists a small block chevy crate engine for sale across 327, 350, 383 stroker and 400 displacements from multiple builders in one category, so you can compare by displacement and price before you check fit and order.

What’s the difference between a 350 and 383 crate engine?

A 383 is a stroker version of the same basic small-block architecture, bored and stroked for more displacement and torque than a 350 at a similar RPM range. A 350 is the safer default if you’re not chasing a specific power target.

What’s the best small block Chevy crate engine to buy?

It depends on the build: 327 for a lighter-breathing classic option, 350 as the universal default, 383 for more torque without a full big-block swap, and 400 for the most displacement available in the small-block family stocked here.

How much does a small block Chevy crate engine cost?

Price varies significantly by builder, configuration (base vs. dressed) and displacement; check each live product page rather than assuming price scales neatly with displacement or horsepower.

Why do UEP’s listed specs sometimes differ from the manufacturer’s own page?

In at least two cases here (a horsepower figure on the 400, a displacement label on the 383), BluePrint’s own page states something slightly different from what’s listed on this site. Both are flagged in this guide; confirm the current figure before finalizing a build sheet.

Does displacement alone tell me which engine is right for my build?

No. Dressed configuration, balance, oil pan style and accessory drive all vary by builder and part number even within one displacement. Run the specific part number through a compatibility check regardless of how familiar the displacement sounds.

Can you help me pick between 350 and 383 for my build?

Yes. Send us your vehicle and intended use through a Compatibility Check or Contact Us, and we’ll help you compare the real total cost of each, not just the displacement and horsepower number.
