Egge pistons
I would be interested in any comments from those who may have used Egge pistons in a flathead rebuild. I have read some negative experiences here on the Barn and elsewhere, yet in talking with Mike Herman at H & H Flatheads, he says that's all they use for builds under 3 5/16" bores. So.........

Re: Egge pistons
I use them quite often. Last set the weight was with in a gram and a half.Pretty close for cast I would think. Not as good as Ross mind you.

Re: Egge pistons
We also use Egge, and have had no problems with them. We also use Mahle, which is a bit more expensive.

Re: Egge pistons
I have rebuilt 3 V 12 engines with Egge pistons and am in the process of rebuilding my 1941V 8 for my 1939 PU with Egge pistons. If there is a problem, I haven't seen it.

Re: Egge pistons
I think the problems you have seen mentioned are a product of aggressive block decking.

Solution, I installed Mercury 8CM heads. Used the balled up aluminum foil practice to do measurements on each cylinder. Everything is fine. |

Re: Egge pistons
I should mention I have a friend who did have a set where one piston was 30 grams heavy. I do wonder if it was a larger piston in the wrong box.

Re: Egge pistons
I also had issues with egge pistons and eldebrock heads and interference due to dome on pistons. Between the crap for heads and crazy domes that were not even close to the right curve I have a sour taste about using egge. I'll stick with Ross.

Re: Egge pistons
Yes we had a similar experience with Egge piston hitting the head , no the block wasn't decked and yes aftermarket new offy 475 heads , can't remember the exact non clearance but it was enough that even with a gasket the high dome piston hit the heads, swap to Ross and never looked back and changed nothing else, so in my opinion something wrong With Egge, Cavet Emptor, I am sorry I won't risk it again.

Re: Egge pistons
I'll take an unbiased approach here.
Clearance issue after a decked block Clearance issue with Edelbrock heads Walt Dupont (and others) with no issues A few post earlier I saw Ole Ron uses EGGE pistons as well. Now I don't have a PHD, so I'll let more talented individuals decipher the info. |

Re: Egge pistons
4 years ago I used Egge pistons on a stock bore 8BA block. Stock heads with the bareset whisker of planing on the block; more of a check than truing. Pistons hit the heads requiring grinding of the heads.

I also am on the Egge piston side. Have not had a problem.

Re: Egge pistons
Finally fired up my AV8 after 12 years construction this fall. Egge .080 over pistons with .050 off the 8BA heads. No problems at all with the pistons. I'd use them again without reservations.

Re: Egge pistons
I'm running 3 5/16 Egge pistons along with Edelbrock 8BA heads. I had to tweak them slightly to get proper clearances.
I had a wonderful phone conversation with Barney Navarro, years ago while he was still with us. He said that there is a real problem in that hardly anybody uses the same dome shape. Some are curved domes and others flattened cones. He wished that they would all would copy the Ford dome for their heads and pistons. This way there wouldn't be interference either on the edges or the tops. |

Re: Egge pistons
I read on the hamb that mike from H&H talked to egge about the different dome tops and they changed it. the thread was an older one too...

Re: Egge pistons
I wonder how many of the ones with head trouble were using heads that had been milled in the past???

Re: Egge pistons
Anytime you replace pistons, you need to "clay" the heads to verify clearance. With old engines is is impossible to know how many times and how much the block was decked, and whether the heads have been milled.
