I had 3 vehicles come to my shop this year with new LS blueprint engines and all 3 were junk. None made the power they claimed and one spun the reluctor wheel on the crank.

 

Engine builder buddy of mine also had a Blueprint LS come in with a spun reluctor wheel.

 

Blueprint isn't the only place that sells engines with false dyno claims. Having said that, it is important to remember that every dyno will read a bit differently. You can bet your ass that most companies that sell engines and has an in-house dyno, that dyno will be "happy". Although, this isn't always the case. Find a good shop... build a relationship... use the same dyno (when possible).

With regards to your specific set up, what are cam spec's? My own experience is that a single plane doesn't always wake an engine up as much as we hope compared to an RPM Air-Gap for example (good dual plane).

 

There are several dynos in a 2 hour radius of me. They vary by 80 hp on the same engine.

Best advice I can give is to always use the same dyno just so you can have a standard to compare each engine against and just be ready to accept that it may be conservative or liberal. It's the guys that seek out liberal dynos just to "prove how good of a builder they are" that really get to me.

 

When the timing chain was replaced, did the cam get degreed/checked?

 

Yes it did.

 

I have several friends with Blueprint Chevy engines. One is the 396 small block, two 489's and their 632. All run extremely well for the price paid, and also come with 36 month warranties.

The 396 SB is in a 3rd gen Camaro with a 4.56 rear. It's a low dollar build. Complete engine was $5000 complete ready to bolt in. Bought it right before Covid. Best run is 7.11 in the eight mile on pump gas all motor. Plenty of street/strip miles.

The two 489's were bought around 10-12 years ago. One 489 had a knock issue shortly after getting it. They told him to not take it apart and just get it ready for pick-up. They sent a replacement and swapped them out without hassle. This is in a beautiful C10 Square Body truck. Guy driving it is 72 years old. Has gone 7.20. 4.10 gear.

Other 489 is in a 1970 Nova. Street/strip all steel car. I believe it went 6.70 n/a, and 6.33 on a small nitrous shot. Zero issues with the engine. Currently has a 3.55 gear.

The 489's were bought by father and son. The other son upped the ante with the 632. lol Also pump gas. He bought it 8 years ago and put it in his 1971 Chevelle. It's a full weight, all steel car (minus the hood). With a 3.73 gear it ran a best of 6.34 @ 110. He tried a 200 shot on it last night, but only went 6.20. I think it might be his $400 Jegs brand converter. lol 632 is impressive. Has power EVERYWHERE. About any stall speed converter would work in the thing, as it has so much grunt. lol I think he just needs one that will handle more power. At the time, I believe he paid $12,000 carb to pan. Has been flawless. Blueprint dyno sheet said 830 hp, I believe.

All the guys went on a 1.5 hour long cruise, lining up with each other and blasting on them just a few weeks ago. Have done so several times. Nothing negative to say about Blueprint. For the price, power, durability and warranty... you just can't beat them for a ready to go pump gas 'crate' style engine.

There are Youtube videos showing their operation, and tours of their factory. Not your average 'rebuilder' shop.

 

Is this the same engine they sell as 491hp with a 230/236 hydraulic roller camshaft ?

 

I don’t think it would gain any et swapping to the single plane with such a small cam. What does it run it now?

 

Since you have the Victor JR intake at hand I would try it out. But not before you make hits with the current manifold if you haven’t already. It would make for a good comparison and tell you exactly what you need to know

 

Bought a 396 sb fron blueprint,Would respect opinions on the intake swap, speak your mind, as it's only nuts and bolts to me.

shouldn't have bought an engine from blueprint, same shit as Jasper

 

That's definitely NOT the case. They design their own parts, have their own blocks and heads cast, go through great lengths to find good reliable performance combos that will last past the duration of their 36 month warranty, and have a lot of attention to detail. If I were in the market for a crate engine (which I am NOT) they would be the only one I would consider.

Below are some videos. Go to Youtube and type 'Blueprint Tour' for more.

guess you didn't read some of the comments about about their engines. I'll pass and so would every racer I know

 

Yes, but everything in the vavletrain needs to be correct; not overkill... just correct. Look at the entire valvetrain system, not just the cam and springs. In my experience, if you are seeing power really nose over past your current peak of about 5,800 rpm, it usually is a sign that the valvetrain is unhappy. If that is the case, it is probably costing you power before peak as well. Just something to consider.

 

i have personally installed 6 blueprint motors in customers cars from ford 302 to the LS,and a few sbc. out of all of them not one problem from any of them. now granted these are just street driven probably not one has or will see track duty.. for the money and warranty ,hard to beat.

 

We went to the prepped 1/4 mile event last night at Kentucky Dragway. This car belongs to my buddy, Scott. Back in 2016 he bought a 632 (carb to oil pan) from Blueprint. It's been in the car ever since. Only time he's touched it, is to fix a valve cover leak. It can be driven on a 2 hr round trip (if you want to buy that much 93 octane) or rip it up at the track. It's the engine rated at a little over 800hp. I think the dyno sheet said 830. Rev limiter is at 6800 rpm. It's backed by a 400 Turbo and 3.73 Dana 60. Full weight car with full original interior, back seat, dash, etc. Only fiberglass is the hood, and he had to install the SCAT Pro Car seats when he did the roll bar. (not lightweight racing seats)

The track had both 1/8 and 1/4 mile classes going on. He ran it both naturally aspirated and on a 200 shot of nitrous. He only made one n/a pass in the 1/8 early in day (80 degrees or so) and went 6.28. After turning on the bottle and it cool outside, it ran 5.84 @ 120 in the 1/8, and 9.15 @ 144 banging off the rev limiter. He was racing me... I treed him bad, and he was chasing my 9.29 @ 146. lol On a later pass, he quickened up the ramp and almost stood it on the bumper! Had never come close to doing that before. 275 Pro Radial on 10" bead locked Weld Pro Stars. He splurged on coated Lemons headers, and said they fit perfect and easy... well worth the steep price. 3.5" exhaust and see through mufflers. It ran 9.8 in the 1/4 n/a last time we were there. He didn't make any 1/4 mile passes n/a this time. He was having too much fun on the bottle.

Back in 2016, I think he paid around $12k carb to oil pan. I think they are around $17-18k now. He's talking about installing a 3.55 gear now, as the engine has the torque of an Army tank. lol

Anyway, if anyone was wanting a review and long term update on Blueprint, here it is. lol

 

My brother in law has a 72 Chevelle with almost the same stuff as this green one, also with a Blueprint 632 but his ate a roller lifter in the first summer he had that motor in it, blueprint sent him a new motor and its just been sitting on the motor stand since ........
