Default Buying a BluePrint 331 Stroker Engine

I am kind of copying the VMFer that had posted about buying a Tuff Dawg crate engine, but I wanted to give you all a little info on why I chose BluePrint. After months of research I came to the conclusion that Blueprint's 331 Stroker was the engine I wanted and I'll tell you why....

- 30 month, 50,000 mile warranty.
- Warranty covers parts and labor and if something happens to the engine and needs to be sent back, they cover R&R and shipping both ways.
- They are going to paint the engine blue.
- They dyno tune and test each engine before it is shipped to me at no additional cost. Ships with results. Gives you piece of mind that the engine will run when you put it in. Most places charge for that or won't do it at all, especially if you don't buy a turn key engine.
- They use new parts...SCAT crank, Keith Black pistons, etc.
- Hydraulic roller cam.
- They will convert it to a front sump setup.
- Customer service is great

Total cost to my door is around $3,400. They say about 20 days to complete a custom build or you can buy their preassembled crate engines. I elected for the custom build. Ordering it tomorrow morning.

All this talk of 331s is making me want to take the one off the pallet in my garage, freshen it up and swap into my car :/

What do people do about fuel pumps/lines when putting these stroker motors into the older cars?

and here is why I don't....

SCAT- been around 30 years, started off doing VW bugs, had terrible results for years with anything bigger than a bug engine, yeah they do a lot of high profiled racer parts for big name racers, but check the sourced parts for yours, they likely come from china and regardless of what they claim their standards of quality for your parts is less than the pro-racers they market.

KB pistons, if its AL forged fine, otherwise it is second rate crap as compared to what can be purchased for the same $ elswhere and of better quality.

Cam- is it a cast cam billet or forged, who was the grinder.....if it's Comp, Crane or Erson, run away period....chinese billets (cast in most cases) from mass production facilities....for the same price again, you can get personalized service and a real quality product.

If you check out gofastparts.com, they are located in Redlands Calif, they handle just about every OEM crate engine known to man, yeah their webiste is crappy but call them by phone and you will get most likely an engine for the same price, with better parts and a warranty that you won't have to ever use.

just my humble opinion.

Snipe - I am going to run an Edelbrock 600 and their mechanical pump with braided line and AN fittings.

Buckeye - From my conversations with BluePrint, they use KB Hypereutectic pistons, SCAT Crank and rods, both new. I have heard some people say don't use anything but SCAT. The cam is a custom grind and not COMP or other. Specs: .543 Intake / .554 Exhaust & 218 Intake / 226 Exhaust duration @ .050 - 112 degree lobe separation. Modified cast heads, hardened push rods.

what should people do for cranks?

when was the last time you used a scat crank and what was the application?

My custom cam is a Comp, not that I mind, just letting you know. Does not match any Comp specs or lobes, just a Comp billet core and box. It was ordered for my by a professional in the industry who I trust and many (not all) also trust. So take that and $1.50 and you can buy a coke with it.

I've read a post in a different forum from Woody at Ford Strokers that almost any crank you buy is going to be a Chinese crank under $1,000. Just have to check it out. He recommends RPM cranks (also Chinese), but apparently they are back ordered quite a bit.

Snipe- My 331 has an EFI bolted to the top so I got a complete fuel kit from Glenn's performance. I like the quality reviews and the turn key aspect. Sumped 20 gallon tank, lines, 255 l/h pump and rails.

66fstbck- Where are you located in Oklahoma? Good luck with the build. Did they tell you what kind of heads they are?

I am in Edmond! I see you are from Tulsa....always cool to see people that are nearby.

The heads are Ford cast heads. If I opt for aluminum (347 w/ aluminum is about $800 more) then I think you get either Dart, custom BluePrint heads or Edelbrock. I don't think BluePrint has a Ford head so it is probably one of the others.

I am actually considering the Atomic EFI to fuel this engine. Probably later on down the road though.

They use an earlier model 302 that uses the 28 oz flywheel. Is the bell housing bolt pattern the same on all of these engines.....will my 4 spd bell housing still bolt right up?

Yhat is a nice price - I'd go with the alum heads if you can swing it - would really wake that thing up. I was looking at ford racing 306 for next engine but this is a good alternative

I'm going to go out on a limb here...but yeah, if your top loader was bolted to a 289, then no problem bolting it up to the 302 factory block.

Braided line to replace all factory lines on the car? Only reason I ask is I'd thought the factory lines could feed enough since I assume the lines were the same across the V8 cars. I knew though the factory fuel pumps had differences across the engine offerings. So my uneducated mind has been assuming if the factory lines can feed a big block then they can feed a stroked small block so long as it has a sufficient mechanical pump.

The 331 I have was a street motor I had built for an old turbo car. It actually is more like a 326 since is standard bore. I used a new Ford A50 block and Probe 331 stroker kit. So nothing super fancy, 351C crank, Eagle steal rods and dished forged pistons. I'd probably just build a new engine over using that even though the one I have only has idle running time it still been sitting for 10ish years now. I'd actually purposes go cast iron heads but to the untrained eye I'd like the engine to kind of appear stock to era specific looks.

Hope that makes sense, I still need my coffee today.

If you can somehow manage to swing some name brand aluminium heads I would go for it..It will really help that engine breathe and make hp...As for the fuel line its a bit of a crap shoot on these cars..Some are fine and some have some have gotten kinks or dents in the lines over the years which restricts flow..Get a good mechanical pump and chances are it will be ok..I replaced mine with a larger braided line ..

Scat's stuff is really good now days. I'd definitely use them over most of the other forged cranks and rods. Scat is now handling their own machining in the US and not in china, unlike Eagle and others. One big difference I've seen is that Scat's taper on the throws is next to none. A LOT of the Eagle cranks need to have the throws turned to take out the taper, as do a lot of other china sourced forgings which are machined in asia.
