Unless money is no object, the accountant in me says define the project's scope and make a budget. Good luck. Sounds like fun.

I use .25" aluminum spacers under factory covers on a '78 T/A. No problem with the scoop vent pipe. I deleted the AC, so I'm not sure if a factory compressor will clear.

Is this lifter now 'pumped up' and acting like a solid and holding the exhaust valve open?

If you saw the valve drop while adjusting, I'd say yes. I'm just a hobbyist here, but I'm surprised you...

I may be the only dissenting voice, but I bought a MSD Ready-to-Run (8528) two or three years ago. It's been trouble free. I agree they are a bit pricey. Others on this board have had good...

I should have paid more attention to exactly when it starts to break up. I'm guessing between 4,500 and 5,000. The Ready to Run does have a rev limiter, and I have it set to about 6,200. When I...

I've had the carb apart a good bit lately, and the pickup tubes are good. I've also thought it would be nice to try another carb, but I don't have access to anything that would be close to this one.
