Re: Pistons

On a side note:
You can pull the oil pan and the heads, then remove the rod caps and push the pistons and rods out the top.

Can this for a fact be done? If this is possible I will go thru with forged rods and pistons, If I can do this work with the motor in the car.

Re: Pistons

Im rebuilding the whole motor since I have to take it apart to switch the pistons so all will be new and prelubed. Any ideas towards a good cam while Im in there?

Re: Pistons

so slow did you get yours back up and runnin yet?

Re: Pistons

The crank and cam won't get touched so they don't need prelube.
You could lube the rod bearings when you put rods in.
As far as the crank and cam are concerned, its just another cold start.
I would pull the motor though, I just like to work on a clean, easy to reach motor if possible, you know?

Re: Pistons

What's up with the Grand Am pistons? Dif compression or something from the Camaro? I found that the 3400 with the AL heads was like a 11:1 because of the smaller bowl in the head... so I didn't use those heads with my 10.5:1 pistons. I was just wondering what was special about those pistons.

Re: Pistons

The alum 3400 heads on a 3.4, with 3.4 stock pistons creates approx. a 12:1 CR. I believe grand am has like a 9.6:1-10:1 CR. so yes pistons carry a different CR.
