Whats the redline for the 12514695. I believe its around 5000 rpm. I don't want to over rev this motor. I had been going by ear,a recent tach installation shows I've been taking it to 3800-4000rpm. With the 4 bolt mains I think she's fine to 5500 or 6000?? Can anyone at Sallee confirm the real red line for me...thanks |

This is a stock GM Goodwrench engine. It is not a GMPP performance engine. Don Abel says that he wouldn't recommend going over 5,500 RPM. He said it could probably handle more, with it being a 4 bolt main, but he wouldn't do it if it was his engine. |

IF IT WERE HIS what would be the max constant RPM when pulling a load. this engine is VERY STRONG for Bone Stock. It's coupled to a 4speed(including granny low) and a transfer case.
This thing just wants to keep on pulling. I just wanted to make sure I wasn't taking it too high, for all I knew the redline was 3800-4000RPM..I know its not a GMPP Engine |

Don, the max. RPM rating on a simular performance engine is 5,800. I think you should stick to Don's recommendation. If he says he wouldn't recommend it, he means that is what he would do if it was his. Sounds like you plan on pushing the envelope anyway. Is it really worth the risk to find out just how far the engine will go before you blow it up? |

I WANTED TO MAKE SURE THAT 3800-4000 WAS SAFE AND NOT TOO HIGH, IS IT???
I DO NOT plan on pushing the envelope! I DO NOT want to blow it up! I want 200,000 miles from this motor. Thats why I inquired!! I just wanted a straight answer on the redline since there was NO RPM DOCUMENTATION SUPPLIED WITH ENGINE.
I haven't taken this engine above 4000RPM AT ANY TIME. My normal shift point has been 3000 and below. I RESPECT Sallee's and Don Abel's judgement. Would he feel safe with shifts at 3000Rpm. |

Don Abel says that 3,000 is safe and about the highest you should go. |

OK!I finally got in touch with The Man that knows this engine after many tries. Redline is 5400RPM MAX. He puts the 12514695 in everything from Tow Trucks to box delivery vans (barns with wheels he called them). He says their Auto-Trans low end shift points are @4500.
He says with the big sodium filled valves(yes that's true!) and heavy rods that thing has you can run it with a load @ 3000 to 4000rpm all day long.
He added that the factory retards this cam by 2 degrees for saftey it will top out @ 5200 +/- 100 He said with the loads I carry (2-3tons) and Man-Trans that I could pull a constant 3000-3500 easy, that I'm only pulling 6 Tons Total and its capable of 10. 4000RPM is no problem. He just laughed...... |

Damn, sounds very strong. is this a truck only motor? whats the horsepower and torque? Whats the price? |

Don, it sounds like this person knows how to run the numbers who every he is. Sounds like you also gave him a whole lot more information to work with then you did us. Don was making a general statement based on average use and pulling load for this engine with the type of transmission you described. I'm glad you got an answer you were satisfied with. Good luck to you on your next 200,000 miles. |

Steve,
Don Abel says the price on this engine is $1,975.00 and a GM core charge of $50.00 + shipping with no tax.
So the total would be $2,025.00.
This engine is a heavy duty pickup engine, but is still a small block 350 stock replacement engine, for those that don't know what we are talking about.
Webmaster says,
GM does not give us any specs for this engine. Only what year vehicles it went into originally and what it comes with. The latest book they have out with even this information was published in 1995.
"1995 Application and Reference Guide"
The horsepower and torque will change from vehicle to vehicle depending on what this engine is hooked up to, in the vehicle it is going into.
I have mentioned to GM Goodwrench before that it would sure be nice if we had specs on these engines just like the GMPP crate engines. Frankly it's embarrassing not being able to answer a simple questions like this, but we are stuck with only the information GM Goodwrench gives us.
We could hook everyone of their stock crate engines up to our dyno and determine what it is for each of these, under a load and fully assembled to run, but the time and cost of doing this would be prohibitive.
Hopefully some day GM Goodwrench will start publishing specs on their crate engines just like GMPP does on theirs. I've told them if they do, I'll post them (or as many as I can) on our web site just like we do for GMPP crate engines. |

Steve,
I've been talking to Tom Sallee about this problem of no specs on GM Goodwrench crate engines and this one in particular. He says that if we hooked it up to our dyno, that with headers and a good carb, intake, etc., he would expect it to put out around 250 HP and 350 ft. lbs. torque. Again, this is best case scenario and we have not actually put this engine on the dyno to find out. Also, remember, like I stated above that what you hook up to any engine will effect it's performance. How much smog stuff, what intake, carb, etc.
I hope this better answers your question about HP and torque. |

Okay, I paid 1820.00+ tax for mine.. I've been told that this motor has approx 390-400lbs torque @ 2000rpm and 265-275hp @3800. Based on the 6 series CHP , With the Edelbrock Performer Intake and Edelbrock 795CFM Q-Jet Carb. I'd say the above #'s are close. Air pump only, No EGR(egr exempt) This thing pulls like crazy. The guy who sold me the motor sells and installs a lot of this particular engine. I think he's VERY FAMILIAR with it and what its capable of. He said I'd get some slack from these statements, he was right.
On any hill no matter how steep, from 2000RPM and up it never slows down. I'll keep you posted.. |

Don,
I showed your last post to Tom Sallee and here is basically what he said. The HP and Torque numbers you have stated are high for what that engine can put out. How do we know this, you say? Well we have and upgrade to the Stock Universal GM Goodwrench crate engine that we have put through the works on our dyno. This crate engine is almost the same as identical to the one we have been discussing here. Only difference is one has a 2 piece rear main seal and the other a one piece. He says that he is almost certain that they both have the same heads on them. On or upgraded Goodwrench Universal engine, we have added a mild performance cam, Edelbrock Performer intake manifold, and 8" HD Balancer. On our dyno, with a 1904 Edelbrock Q-jet carburetor, we got 285 HP @ 4,600 RPM and 355 Ft./Lbs. @ 3,600 RPM. He also said that the red line on both of these engines is more like 5,200 RPM. Though like Don said, you could get away with slightly more that this, but not recommended.
I know that all this is true and not made up because I obtained all the dyno results from our speed shop and have them in front of me right now.
Also our price for this Goodwrench Performance 350 285 HP engine, GM Performance with camshaft kit, Edelbrock Performer intake manifold, and 8" HD Balancer is just $1,795.00 + shipping and no tax. (At this time.)

Tom also, mentioned to me, since we were on the subject, that our speed shop has been working on higher low end torque version of this engine for just towing and hauling applications, just like you have been talking about. I can't say when they will have it out though, but they are getting close. |

Well regardless of the actual hp and torque, this 12514695 is a very strong 5.7L engine. I'm very happy with it. Towing a 2-3 Ton trailer is no problem at all, and accelerates up a grade.
The 81 Suburban 4x4 weights 6250lbs with me in it.
Well make sure that baby has the sodium valves. From what Rich told me thats the $$ difference between the 2 engines along with bigger rods and the cam timing.
He would'nt sell me the 10067353 and that it wouldn't last 1 yr in that truck. "Trust me" he said. This is the only motor that he would
give the 50k-3yr coverage on, with towing I had in mind. Anyway enough said.
Thanks for all the input guys, much appreciated. |

Don,
Our Speed Shop says that the sodium valves, etc., that you are talking about really aren't needed for what you are doing. The 10067353 Goodwrench Universal engine is plenty tough enough as is. Another point worth mentioning. GM Goodwrench warranties the engine, not him. If any GM Goodwrench engine fails during normal use and during the warranty period, which is what you are doing, then they will cover it. It doesn't matter what that guy you have been talking to says, he isn't warranting the engine.
With the difference in cost between the two, it's smarter to use the Universal Engine. |

So let me get this straight. What your telling me is that you'll sell me p/n10067353 for a 81 3/4 Ton 4x4 Suburban with M in the VIN that weighs 6250lbs. I'm telling you up front that I'll be using it for HEAVY TOWING on average of 2-3 tons and up to 6TONS for long distances up to 8-10hrs non-stop up steep grades to high elevations of 6-9000ft. and GM will warranty it for 3yr/50k.
When I 1st called around for price quotes($400 difference) Burt Chevrolet, Scoggin Dickey, Jim Pace, Anderson ,Courtesy and Billings Chevrolet among others all quoted me the 12514695 engine for the above application.
When this motor ever gives out I'll buy the 10067353 from you! |

Don,
I hate to sound stupid, but, why would you consider towing 6 tons uphill 8 hours a day with a small block. Wouldn't it make more sense to buy a big block work horse that would do it for years rather than a small block that might be iffy at best with those loads. If this is for your work we all know time is money and a warrenty will not cover your down time while they replace your small block. |
