10 Best 383 Stroker Crate Engine (2022 Updated)

So – went back and forth over whether to have a BBC done local and ran into this cool 396 on summit. Was worried about parts backlogged for a local build – summit had this ready to ship/free shipping and cheaper than on Bprint website and vs other competitors.

I just pulled the trigger. Got here w/in 48 hours. Six weeks later – it is in and pretty well tuned in my 78/4speed Z28. Now, to be fair, I’ve got 3. 73 gears – but this screams. I did go kinda easy for a week or so (and still am) but runs really good.

Off idle, cruise, WOT. It’ll tear through 1st/2nd gear with 28 cooper cobra’s. Am running 1 3/4 doug’s (i’m a pontiac guy by trade – we dont’ run 1 5/8’s) and just 2. 5 pipes/xpipe. Only minor issue is I don’t know chevy’s and correct flywheel/clutch/H balancer and bolt – were not fully clear – but I figured out okay with a few tech calls.

Am happy w/ power, quality and happy with purchase. Nice motor!.

This engine was put in my 1965 Impala SS convertible. Car had frame off restoration 6 years ago. Had to replace the 396 big block in it. This small block 396 is amazing! Way more power and performance.

Looks and sounds great too! Summit techs were great in answering questions. Been a great experience.

Fit perfectly on the existing motor mounts in my Geo Tracker! Complete install in about 20 minutes with just me and my 9 year old. Very excited about the dramatic increase in gas mileage!

Amazing clearances, the block was perfect in terms of clearance and quality I will be buying another block specifically to use this crank again

very nice crank, even had scat cast onto it. save the money & buy speedways crank. i put speedway’s windage tray on it too.

great product for my eng. build.Shopped around ,the best buy.

I spoke to BluePrint several times with different questions about the engine before purchasing. I found them very helpful. The engine runs well with lots of torque. The only problem was that the shipping crate was damaged during shipping.

After opening, there did not appear to be any damage.

Could not be happier with this engine. It is everything that is advertised and looking forward to putting some miles on it. Great oil pressure and the temperature runs 20 degrees cooler than the healthy 350 I replaced.

This is a nice powerful engine, I’m still going by the break in guidelines but after that I sure this motor will last for quite some time.

Very pleased with how well this engine runs. Had a small issue with the Holley carb leaking into the intake after shutdown. One call to Blueprint and they sent out another carb immediately. Great customer service! Put this in a 79 C10, TH350 and an FTI ESR3082 converter.

Truck is very quick even with 3. 08 gears. Thanks Blueprint and Summit!.

Came exactly as described. It even has a chrome fuel pump installed that I didn’t see listed as an included accessory but was a nice surprise. Very fast delivery. Also very impressed by the Dyno numbers that it showed on the sheets sent along with it It’s going into my 1975 Chevy Caprice Classic convertible that I’m restoring.

Factory was a 400 sb with only 175 hp. This should be a nice improvement??.

Replacement for the 210HP 350 in my 1976 Corvette. Mounted to the re-built Borg Warner T10. Summit was super helpful with flywheel, clutch, and starter options. Edelbrock 2701 intake and 1905 AVS2 Carb will fit under the stock hood.

But you have to use a smaller air cleaner and remove the insulation from the hood. Flowtech 31106FLT headers fit perfectly with almost no clearance issues. The engine runs beautifully. Revs strong and pulls hard.

Idle is nice and smooth, not too lumpy. Vacuum runs all of my accessories (headlights etc) just fine. Could not be more pleased with this purchase!.

The packaging was perfect. Shipping was quick. Blueprint and summit have been nothing but impressive to work with on ordering any additional parts I needed. 63 miles in on my break-in and no issues at all.

The engine itself definitely looks nicer than expected. Looking forward to see how many miles I can put on it. Installed in 1972 C10.

Received the dyne sheet that stated 413HP with 414 ft/pounds of torque. Great motor. Had to buy new flex plate/bolts, harmonic balancer & starter, something to keep in mind if you’re replace a first generation small block.

I used the recommended 30w break in oil, no issues. Be nice to use off the shelf motor oil from now on. Some ticking, may be the roller cam/lifters, may be normal. Great motor for the price.

Engine arrived at my house within 2 days from the time I ordered it. This was with the standard free shipping mind you. The engine was also packaged up very well. The dyno sheet came in at 430. 7hp and 470.

6ft/lb which was more than advertised. My engine did not come with the valve covers or intake manifold shown in the picture. The valve covers were actually much nicer than the picture and had the blueprint logo stamped on them.

The intake manifold my engine came with had bolts that went straight down into the heads instead of the standard ones that bolt in at an angle. (See Image) This is not an issue for me but it could make factory accessory brackets difficult to mount.

Summit needs to update the pictures on to reflect this. Distributor was very nice however it was black instead of red. It also had the firing order painted on it. Worth mentioning, the distributor had the #1 plug marked where the #2 would normally be.

This does not mater though as the firing order was still correctly marked they just decided to rotate the plugs one space over from the standard configuration. Not sure why they do this but I plugged the wires in where Blueprint had marked them and the timing was perfect.

Another thing to note is that the spark plug holes where not in the exact same location on the Blueprint heads as the were on my GM heads. I was unable to fit standard length sparkplugs without them hitting the headers at Cylinders #5 and #6 so I had to buy shorter plugs designed for headers.

This will obviously be dependent on what headers you are using. 2 of the bolt holes on the front of the drivers side cylinder head are about 1/4″ lower than the standard GM location on my 350 from 1982.

The brackets still bolted up fine they just sat lower on the head. Because of this, I was unable to mount my factory A/C compressor. This is not important to me though so I just removed the A/C all together.

I know that most aftermarket accessory drives will bolt up to these heads no problem but the factory accessories will likely be difficult to re-use without modification. The only other thing worth noting is the Mini-starter I have required about 1/4″ of shims to engage properly with the flex plate.

This is no big deal just note that a standard mini-starter will likely require some fiddling to get right.

I installed this engine in my 69 Camaro. I wanted to stay with the original size 350. Engine came as pictured except it had painted valve covers. Engine started on the first crank, good oil pressure, no leaks, temp runs at 180F.

Installed a 2500 converter. All it needed was idle, float level and choke adjustment. Ran the 500 mi break in, no problems. The engine is very smooth and runs strong. The cam does not have a lot of lope at idle.

After the break in I replaced the stamped rockers with 1. 6 roller rockers and that gave it a nice lope at idle, plus a little more power. The engine sounds great and runs even better. I wouldn’t hesitate to buy another.

Very good choice for the weekend cruiser.

Advertised as double roller but received a single roller timing chain with a plastic timing cover; wow!. Shipping crate didn’t hold up too goodeither and was falling apart. Reached out to blue print engines and they told me the single roller is what their product description says for the part number and well the timing cover is due to supplier issues and I could “just” replace it if i wanted something else.

That being said, Summit Racing picked up the ball and did what they could to resolve some of my issues. Summit is AWESOME.

As always, the items I purchased were delivered quickly. This kit arrived in perfect condition with all the necessary parts to install. I’m very pleased with this purchase so far. I can’t wait for the initial start up.

I’ve done my research and the parts I selected along with this stroker kit should make well above 400 hp.

Pistons was a little dirty and scuffed up. But seemed still good assemble motor and in less than 500 miles the crank broke in half and destroyed my motor. And it was assemble by a professional shop. very disappointing all this work in money now no motor.

Was making under 500 hp.

Everything is serial numbered and came with specs on rod weights, bob weight, weight matched pistons, and a certificate showing the rotating assembly balanced as a unit. So much better than buying parts here and there that arent matched.

This is a system that should make a motor that will run a long, long time.

Everything showed up perfect and rust free, ring gaps were perfect out of the box for my. 040 over 350,tolerances on the rod and main bearings were all well within spec. Have yet to fire the engine but I’m expecting good results.

A+ for eagle and the customer service from summit is second to none!.
