I look at it as "attention to detail". I have the time and the equipment to do the job, and at 1035gms, the pistons are just too heavy. I won't be lightening the pins or rods. What balance factor do you favor?

You misunderstood. I am making the cuts on the bottom of the decks, not the tops. Compression ratio will not change (SCR = 9.5 to 1).

I am well over $1000 on this set.

Why would it rattle? Holes will be 1/4" deep.

After examining the pistons, I found the following (red) areas to be candidates for removal of excess metal. By now it should be obvious I am going to do the job myself. I am no expert in this arena, but I am gung-ho. I'll use my Powermatic drill press to drill the four holes in the side...

One of my pistons (No 2). OD is 4.3875" and weight is 1035gms. Even feels heavy. I think I can get them to less than 1000gms in my mill. Anyone have an educated guess for the minimum deck thickness for the piston? See the line right above the top ring land? That is the bottom level of the...

Any of you ever seen the front shocks on a 1950 Buick? Buick was ahead of its time.

Been doing a little due diligence. Weight of a 409 is 620 lbs and the 248 comes in at 746 lbs. That's a net loss of 126 lbs in the front end of the old girl. Replacing that CI behemoth intake manifold with an aluminum one will reduce the front end weight another 20 lbs or more. Exchanging CI...

Yes. She is a sweety. A bit cantankerous at times, but lovable. I don't recommend raccoons as pets. They have a vicious bite, and they can wreck your house in one afternoon. Young ones never quit moving. They don't sit in your lap like a cat. I wish I had an 11 second street car. That it...

Rats!

Using your mouse, right click on the chart and see if it gives you the option to save the chart.:write

Don, If the simulator allows you to save the charts, save them with a ".jpeg" extension. Then load the chart.jpeg with the forum attachment function and you are home free. Either that or do like I do and get one of your grandkids to do it for you.:read

I will be sending these pistons to Rebco for lightening. The kicker is I will have to rebalance, depending on the amount of weight removed. I don't remember the original balance percentage. I realize the ideal percentage is an art form known only to those who have practiced the art for ages...

I had made my own guide plates since none existed in 1991 that I could find. I will be replacing them with a more "modern" set. Mine were case hardened with a deadly poison whose name I cannot remember right now. We had a few fans blowing for that job.

Gonna use the Shorty ones. Can you post the curves with the Edelbrock and Shorties (I will have a 2" pipes with Flowmaster's) from the simulator?
