I would think that they would cool faster because of the thinner cylinder
walls.

The side walls on the 88's are very thin compared to "stock" pistons. They
have to be in order to fit the case without machining.
Consequently, with less metal to transfer the heat there is a greater tendency to overheat and distort.

Would someone explain to me what is wrong with the slip in 88s.I don't think
it would be because of a cooling problem.What is is?
A" mild"cam should give you good power thru the low to mid RPM
range.Don't use a radical cam unless you are going to keep the wick turned
up. My.02.

The builder of my first engine warned me that it would not idle smooth, that it would "lope"

"mild" is relative. I consider anything above a 110 to be a more radical
cam. The last 110 I bought, I put in an otherwise stock engine and it
wouldn't idle. So I took it out and put a stock cam in and it purred like
a kitten. For most engines above 1680cc, you just about have to run a larger carb or dual carbs.

so if i have a 'mild" cam, is it an engle 100?

I finally got my hands on three used 88 pistons for the motor I had in my
bus. So I am putting that one back together now. IMHO slip in 88
cylinder
walls are too thin. The machine in 88 walls are very thick. As for cams,
My
favorite for a bus motor is a scat c25 or engle 100. After my last
experience with a 110, I will probably never put one in a street motor
again.
The guy I got the used 88s from also had a set of new forged 88s for a
78
mm
stroker crank. Pistons only for $50.

I run 88mm Forged pistons with a 110 engle cam , the 88's are slip in, I haven't had any trouble ,butttt ,I think I am extremly lucky , I also change my oil almost after every trip , 200 miles or more, Bob says that his theory is that the folks break the bottom of the skirts as their installing them , butttt, I know I wouldn't have used 88's if I had read all the horror stories first. 1776 is what I 'll probably do next , with straight cut cam gear , . Good luck , 88's or rearist of the rare at most shops
