You shouldn't have to change out the pistons to higher quality ones so you don't smoke them, and you shouldn't have to get better rods.

Just a shot of the rings fit and waiting to be installed on the pistons.

What an oily mess. 2 more spiro locks - rings and in the holes they go.

Info , you mind divulging what gap you use on the top and second ring, on a 4.5 bore blower motor.
I used the specs for moderate boost/nitrous on this one.
The bore is 4.560
.023 top
.025 second
J&E moly ring set. Each brand is a bit diferent. Total Seals use a much smaller second ring gap.
Big boost and race gas another .002
Oily workbench mess now in the engine. Perfect .005" in the hole as planned.

2nd ring gap is wider than top ring?
Gapless 2nd ring?
Moly top and cast iron 2nd?
Sorry for 20 questions..not familiar with ring set.
J&E moly ring set.
Moly top - iron second.
Second is not gapless and gap is wider than top.
So I read up on Info's ring gap deal. He says this:
"I used the specs for moderate boost/nitrous on this one.
The bore is 4.560
.023 top
.025 second
J&E moly ring set. Each brand is a bit diferent. Total Seals use a much smaller second ring gap.

So I go to J&E's web site and double check his work. Info says that he used the "specs for moderate boost/nitrous". Ok well I see they have a table (http://www.jepistons.com/pdf/piston_instrc4032.pdf) that says for moderate boost/nitrous use this formula:
Top Ring = Bore X .0050"
Second Ring = Bore X .0055"
Oil Ring Rail = Min .015"
So lets do the math,
Top Ring = 4.560X.0050=.0228
Second Ring = 4.560X.0055=.02508
Following J&E specs, looks like Info is right in there....
