America baby. I would not trust a valve or a seat made in CHINA on my engine. Let alone the machine work installing the seat. Or the springs for that matter. Might want to put a small flashlight under a Speedmaster seat and see if you can see some light. |

Both combos should be making more power. Mismatched parts. Cams are too big for what you get back. Not a good test, does not prove anything other than less money.
Need higher end efforts to get a good idea of their potential. Sorry. |

I agree. Someone asked for results with SM heads. He didn’t ask for opinions.

I agree with this...I wish I was more familiar with who is who on this site...That would make it easier to know what their opinion is worth.

On pump gas hauling doing Drag Week hauling a trailer with all your Goodies driving a thousand mile's a week and make it trough it all. Yes with more porting and better intakes (mine are off the shelf) And better carbs and maybe more cubic inch's, But both of these Motors were built with used parts good part mind ya but still used. Lets see what kind of power you can make. Since I've dynoed a Couple motors I know it's not that easy to make 600+ HP. Show us your dyno sheet when you do your motor and we;ll evaluate The power you make and I will applaud or I will ride your ASS LOL GT. |

Thing is, if you can not make 600+ HP on pump gas(E85, 13-1, not really) .264 roller cam with 318cfm heads something is wrong. I mean, its going to unless the cam is 8 deg retarded.(buddys engine) Your engine has two fours on a tunnel, 1400 cfm of carb with a .275 @ .050 cam and 11.37-1 CR. Its simply going to make 600+ HP unless something is very wrong. You did port them yourself, saving money. Nothing wrong at all with the power you are making. Just not a high end enough build to give a strong "opinion" as to these Chinese heads are better than our USA Edelbrocks. The 461 I am building at this moment will not see a pump. It will see weight, ET and MPH and go from there. No used parts, well thought out Sparred little expense. Cam I am using made 815 and 865 HP on pump gas 535 and 505 engines. And will post what it does when ironed out and folks can say what they want no problem. To me I would need to see a "wow" engine before I would think those Speedmasters are any better. Have not yet I need that before I throw my country under the bus on this. |

Unless someone wants to go through the time and expense of welding them up and re drilling pushrod holes. The Ti valves (can SM take 2.25 ") the epoxy, the max effort. Not happening. Maybe I am wrong but I doubt we will ever see a Barton, Marcella or Gabby Speedmaster max effort head. I would trust their opinions on how much power, how good those heads are. |
