I may be able to have my motor dyno'ed!A friend of mine was telling me about a guy in town that just bought an engine dyno, and he's been testing the bow-ties that run at a local stock car track. My friend will look into whether he can test my 351 Cleveland for me, {after I swap valve springs, of course} and what it would cost. It would sure be fun to see what my motor pulls! ------------------

Steve buddy, as one who has lots and lots of Dyno experience, let your friend practice on another guinnie pig first. Been there, done that!!!!! Very costly error in judgement on my part. I can elaborate if you like and give you some do's and don'ts. Alex------------------

Scott, I pounded the hell out of the dampers.
They must have gotten coil boil, while I made sure the springs had plenty of clearance, I overlooked {or took for granted} the dampers.Check out the photos at the bottom of this page; https://mustangsandmore.com/ubb/SprintResto.html Alex, please give me all the tips you can! ------------------

Steve a friend (still surprisingly enough) has a well known brand "x" engine shop in the Chicago area. They do tons and tons of big motor nitrous and small block roundy round engines. He invited me for a "free" dyno session with one of my engines. I questioned his experience with FoMoCo and got the "well an engine is just a pump, and the dyno knows no difference speach"! Well, the opperator deffinatly don't know the difference. Most non FoMoCo dyno shops, do not have 1. bell housing, 2. headers 3. a data base program. After 2 days of fitting, filing, cutting, and adapting we were ready. It took 5 to 6 pulls just to get the water break set close. Not knowing just how "peaky" 289's are, and not knowing when to lift can be quite detrimental. SBC's don't fall off anywhere near as fast as a Ford does. Several bent pushrods later, I said enough, and aborted. End result was an overheated engine, beat up valve seats due to repeated float, and an unhappy me. Worst thing was that no usable data was ever recorded. After 10 or 15 306-347 type 5.0 engines he finally got the hang of it. Mine was only seriously wounded. Many of the others were not so lucky. 3 fatalities of the next 5 after my "guinnie pig". Moral of the story is, let the brand "x" guy find a practice engine first and get used to the peakyness of SBF's.  Alex------------------

Steve, I remember seeing those photos a year or so ago. You're as slow as I am putting engines together. After much thinking, I decided to go with dual springs. It seems like a better combo with fewer harmonics to worry about and longer lasting springs. Better rev potential too. I'm curious about how Tom's engine is performing now that he's got his rev problems cured. Any word Tom??? IP: 63.195.124.102 |

"Steve, I remember seeing those photos a year or so ago. You're as slow as I am putting engines together."That's a heck of a trick, since I only took them a couple of months ago. LOL The motor is sidelined while the car is being restored. ------------------

Well, I just got a phone call. Turns out those bow-tie boys "...just don't do Fords..." {well la-de-dah} I don't blame them. If you build brand x small blocks, you really don't want to dyno a Cleveland. They did recommend a Ford engine builder {Butler-McMasters} in Hallowell, Maine. {about an hour north of here} I've heard of them before, I just didn't know they had a dyno. ------------------

Hey guys the mach is currently sidelined while I replace or repair the fuel tank (clogging up fuel filter), repair trunk floor and replace tail light panel. Thanks, TomIP: 208.165.103.2 |

Yeah, it's always something, eh?Steve, I guess my memory ain't what it used to be. Usually more time has passed than I thought. In this case, it just seemed like more time had passed than really did. Good luck with the springs. I presume from the dyno thread that you were talking about taking the block to be dyno'd. What about a chassis dyno. Will that give you the data you need without having to worry about bellhousings??? IP: 63.195.124.102 |

I'd love to put my car on a chassis dyno, but it will be quite a while until the car is back together again. {I am just as slow as you thought I was.}But for now I'd thought it would be fun to run the motor and see what it actually puts out. So far, I've run my motor through about 4 desk-top and web site dynos, and got a 4 different results. {ranging from 375 to 550} The one I believe the most right now is one that used my 1/4 mile mph and car weight and it said 434. That seems more realistic. Putting it on the dyno will end all my questioning. "Like the saying goes, when the green light drops, the bulls**t stops!" ------------------

I talked to a friend at work tonight and he said everyone around here wants $300.00 or so to dyno an engine. True?IP: 209.222.80.160 |

Here's what I found when I called Butler-McMaster in Hallowell, Maine. {207-623-8895} They are the nearest people to me with dynos. {I found out they just took delivery of a chassis dyno.For an engine dyno, they have a Superflo 901, and they charge $350/day. They say most guys hire them out for a day, some guys hire them for more than that depending on what they need to test out. I need to bring a starter, carb, {I can use one of their test Holleys, a 600 and an 850.}
ignition, headers, and a means of operating the water pump. The guy I spoke to was named Steve, and he said they were dynoing a 351W stroked to 427 ci, and so far they've gotten 720 horsepower out of it! Butler-McMaster is a Ford oriented machine shop and a Ford Motorsports distributor. ------------------

$350 a day is a bargin Steve. Most NHRA engine builders charge $500 a day, but they supply everything except the carb. Alex------------------

a chassis dyno may be more relevant though,this is what you actually see on the road and will show up losses thru the transmission and rear end that can be a source of free HP.headers that fit a Mustang will not often fit the dyno,turning them upside down blocks part of the port dyno headers may make a bunch more power but can't be run in the car,so whats the point? Kittle DYNO note here...a buddy tested a stock Boss429 engine on a dyno last year,it made 375HP they never tried headers or a bigger carb, i was surprised as i thought those things were likely underrated  IP: 209.167.212.192 |

I'm thinking that I might wait and go the chassis dyno route.It will probably be cheaper, {no set-up time} and it would probably give me more useful info. ------------------
