Parts for an engine rebuild
Posted by: krfjkm ()

I am getting ready to rebuild a 140 engine and am starting to source my parts— I usually buy from Clark’s but thought I would check here first as I am getting ready to spend some $’s.

Here is what I would like to buy:

— OT 20 cam or Isky 280
— 60 over forged long skirt 2206 pistons

I have my heads and also have a bolted flywheel.

Anyone have any ideas or do I just call Clark’s?

Thanks!

Good luck finding a new set of "long skirt" TRW pistons. The new ones are short skirt, but supposedly still forged. I think there was a post on a new set here not too long ago.

You do have other piston alternatives depending on what you want to spend. Get everything balanced.

In addition to Otto and Isky, check out Ray Sedman cams profiles that he can base on your specs, american-pi.com

Hello,

Go to Ebay and put in this item number: 162673218942. They have a really nice set of TRW .060 over long skirt pistons for sale. They look brand new, but state they are used. From the pictures, I can't tell. Hope this helps.

I like Clarks forged pistons with drilled oil returns. I would probably do .040 as cylinders get thin and unstable with .060 although probably okay with full fin cylinders. I would do extra clearance for forged pistons even though Clarks is not suggesting it. I'm doing a 140 with the TRW Speed Forged or whatever they're called pistons soon, I liked what people were saying about them in a previous thred here last year.
I'm not sure Otto cams are the same profiles they used to be. Especially suspicious when they don't come with a cam card. I might do Isky 280 again soon.
