Re: Compare 89 leaded gas to 91 10 percent ethanol

When I had my junk dyno'd my guy wouldn't even supply fuel unless I was running what he had in stock. Told me to bring what I was running in the car....

Re: tall deck and intake spacer plates

I'm running a big block but have spacers. I run gaskets on both sides, only silicone the end rails and very thin coat around the water ports... 10.7" deck on my stuff running a 10.2" version intake.

Re: Vacuum Fitting

You'll need two fittings. You cannot connect a pcv and vacuum accessory together, as the pcv is just a controlled leak...I've tried it in the past and failed miserably. You need a fitting for the pcv and one for the vacuum. How about instead of drilling the intake, adding a 1/2" spacer under the car...

Re: Oil drain back

Oil drainback lines from the heads should be plumbed to the oil pan. DO NOT USE the ports off the oil filter housing.

Re: Compression/Nitrous

Depends on your ultimate goal, but compression is only one part of the puzzle. Camshaft and combustion chamber are HUGE factors in this. On my junk, I'm at 16.5:1 static, and camshaft was custom. My stuff was set up to spray at high altitude, so I'm running a bit more compression and different profi...

No the OP my bad, but how many runs did you put on your rods?
I can't even begin to tell you...I know more than 1000 before I ended up with them, and I ran them at least another 500 or more......

Re: Service Life of Steel H-Beam Rods

I had steel H-beam rods in my last engine. Was making a bit over 1100 hp. Those rods had been in three different engines, several different power levels. They had been given new rod bolts twice, new pin bushings twice, and resized twice. When I finally kicked out a pair of them and killed my engine,...

Re: Total Seal sold to Equity firm

I wouldn't worry about Total Seal going anywhere. As long as Matt is at the helm, it's good. I might be wrong, but I believe that Matt needed the help of that equity firm to purchase the company. He's been calling the shots a long time there and finally decided to pull the trigger and make it his mo...

Re: Tips for storing blocks in high humidity environments

Maxima chain wax. Very much like cosmoline. Get it at your local motorcycle shop. Couple of good coats and it can sit for years. Takes a bit of effort to get it clean after, but better than paying to machine away the rust

Re: 7* vs 10* valve locks

One of the biggest reasons for the 10* locks was to stop pull through on the retainer. At really high spring pressures the locks would have a tendency to pull through the retainer and drop the valve. Going to a 10* lock stopped that for the most part. Good thing is today we have substantially better...

Gm used the shorter rod in the 400's so they could keep the pin height the same, just increase the size of the piston to fit.....was easier than making a whole new piston...
