Thanks for the info paul.
And for the new power plant I've figured the linkage problem out and it works great. The motor is ready to be installed in my firebird and hope to have it in by the end of next week and maybe take it for a test run. whether permitting. I was in the garage cracking the throttle on it pretty heavy and watching the boost gage, Well it was well over 15 psi I know this is free revving but WOW I think this is going to be an animal. I'll let ya know. Anyone know if this psi free revving will compare to be close to the same pushing the car? GT. |

I was running the blower motor some more and this thing will peg the gauge.
My friend was watching the gage and said it was over 20psi of boost. That's way to much exspiesly for this motor. from BDS chart it says it's making around 17:00:1 compression. That's good race gas for sure. I'll probably switch the pullys back so it's under driven to take some boost out of it. Maybe get it around 12 psi plus keep it at around 5500 rpm's as I don't have a tach hook up to the motor yet. To Be Continued!!!!!!!!!!!! GT. |

Here is a few pics of the heads I'm going to use for this 80-firebird. The before and after porting. There 1968-17 heads that someone had already installed bigger intake valves. They only did a very short throat cut and left a lot of material that I had to grind away. There 78 cc and should work good on this 455 motor. That last cam you posted paul is the one I have but I think I'm going to use a little bigger cam. It's a ultr dyne .485-507 lift And 231-239-dur on a 110 lsa kinda similar to a raiv. GT. |

These heads are at 78-cc so I can remove the material I need to
Get the compression where I want it which will be around 9.7. I'll know more when I do a mock to see where the deck height is. Thanks for the info on the cam srec's Paul. GT. |

I finally drove the firebird with the new blower motor.
I drove it to lunch yesterday, I did a few short blast with it nothing real hard or heavy but it feels pretty strong. I replaced the front coil springs cause with the other ones it sat to low and now it's way to high so I'll have to cut them some to get the correct ride hight. And I've got to get a better alt cause this one won't keep the battery charged. After these fixes I'll do some hard blast with it. Stay Tuned GT. |

The only bad thing about finishing a car so late in the year
Is the bad weather you have to contend with to get your car out to drive it. Seems like I go through this every year But I've got six of them going this year so far. My goal was seven, I've still got two months. Will see. I'm going to drive it tomorrow to lunch I'll let ya know how well it runs guys. And maybe a vid this weekend. GT. |

Oil Pump Pick Up
Maybe you already did, but if you haven't, I would either Braze or Weld that Pick-Up Tube to the Oil Pump.
If you haven't and it's working for you, so be it. But, if you ever lose Oil Pressure, look there first. My $0.02 Larry S.

Well blew a head gasket first day, Any thing over 5500 rpm it don't like it.
Still had a good time and a buddy finished the event so it was a good time. GT. PS He was driving a 73 LeMans 455 power. |

I'm definetly pushing to much boost that's for sure.
If I could get it to go through the traps at no more than 5500 I would probably be ok but I'm not going to do all that's needed for this car because this motor is for another firebird I have. For now I'm going to swap pulleys around for less boost or just leave it and have a fun street car. The head gaskets were the ones that came with it when I got the blower. I bought the intire motor setup complete motor blower carbs every thing just split them up to make two motor combinations. I believe there the ones butler sells for this app. I'll replace the head gaskets And switch pulleys for now. Drag week is only two months away So I've got to get testing with the Tempest plus go to Norwalk. GT. |

Well it wasn't a head gasket, Torched a piston.
So it's time to put the stroker motor back in this one. I'll repair the blower motor later. To many hot rods, turning into a second job GT. |
