Re: Power Brakes and Low Manifold Vacuum at Idle

I watched the Leed video on their site. They sure sound quiet. Can you even hear it kick on when the engine is running? As fast as it pumped up on the video I would think a vacuum canister would make run less. https://leedbrakes.com/c-1183501-vacuum-pumps-parts.html?gclid=EAIaIQobChMIz4-FibXL7wIVUPD...

Re: Cylinder Pitting

One of the pit’s look pretty deep. If it was on the bottom of the cylinder or above the rings it would be ok. Looks like to is in the ring seal area though, I would say yes in the sleeve.

$4500 for a 66 Lemans Roller down by Branson, MO...Makes the first 66 on this thread look like a steal, rougher than it looks in the photo.

Re: Pontiac Electric Division

I think it is a cool idea to have a electric vehicle branch of GM to carry the Pontiac name. Electric cars are neat in there own way. The tq that the wheel motors make gives them unbelievable acceleration. They have the same tq off the line as they do at full speed. Some of the hybrid super cars tha...

Re: Pontiac Promotional Videos versus the World

Another cool old Pontiac video. The head and assistant head of Pontiac engineering squaring off a 70 GTO against a 71 455 HO GTO Judge. Appears to be at the GM proving grounds. Video says RA4, but I think the 70 is a 455 car. And the winner is.... Enjoy 8-) https://m.youtube.com/watch?v=dHTu5jaT_PU ...

Re: Pontiac Electric Division

If it was something like a Tesla. Performance wise, with that 350 mile distance, I like the thought of it. If it is something like a Volt, UGH. No thanks.

I wonder how many times I would have to charge it to get to the 350,000 mile my Yukon XL has. :lol:

Re: Budget Pontiac Engines comparisons: Mild to Wild

Arp lube, arp studs, torque in 3 equal steps, 110 ft lbs, 130 ft lbs on the back 9/16. Of course I have my assistant helping 8-) I tried ARP main studs and some Milodons. The ARP’s have a higher tensile strength 200,000 versus 190,000 on the Milodons, which can only can be torqued to 85 ft lbs. You ...

Re: Budget Pontiac Engines comparisons: Mild to Wild

Final assembly. Girdle requires longer main studs for the bridge supports. Some more trimming for clearances. We use a min of .060” for anything rotating. Very lite coat of rtv on the pan rails, held on temporarily by the pain rail bolts. 79CA10B9-DB48-4EEA-A497-F61435F8955B.jpeg C801A3B8-5B81-474E-...

Re: Budget Pontiac Engines comparisons: Mild to Wild

Here is a place I had core shift on the exhaust port and hit a water jacket. You could stick 2 fingers in the holes, pretty much straight below the sharpe marks. I need to finish smoothing it up, all said and done you really won’t be able to see were it was welded. I have done many head repairs like...

Re: Budget Pontiac Engines comparisons: Mild to Wild

More head work. Here is the view of the intake port, a 1.77 valve will drop all the way down to the guide boss. For reference Jim Hand’s porting stops at 1.66 up on the bowl. I am closer to 1.9 in the bowl and open the port window more on the short side. I usually use 45* valve seats. I used 30* on ...

The short block on the T/A engine is getting close to final assembly. I can install the pan for the last time. 8-) I have a calibration kit from Cliff’s performance for the qjet. Working on heads right now. We do all our own porting. We built a flow bench years ago, I haven’t flowed these head yet. ...

Re: Tires that last! Time not milage..

What tires did the mustang get? We caved and bought some BFG’s goodrich 225/60r15s to replace the Goodyear’s eagles I had on the front of the charger in the earlier picture. Since the back are 275/50r15 bf goodrich’s we will have a matched set. They were $129, seemed like that size was reasonably pr...

Re: Tires that last! Time not milage..

Working on our 65 Dodge Dart GT today. Searching through tire options and went back through this thread. I thought I would try some Mickey Thomson sportsman s/t 255/60R15. It is pretty much the biggest tire that will fit under the back of the car. Ordered them through jegs, and bought a set of jegs ...

One place that comes to mind that is different than an A body is underneath the car back behind the spring shackles there is a seam were the back panel attaches to the main truck frame that rust out that goes across the back of the car, if it gets bad enough it will get up into the trunk. Even a pre...
