427 piston dome volume

[henny496]

Hello
Does anyone have any info on a TRW piston L 2268 . It is a dome of about .300 , closed chamber
I think the 11.1's are .140 high on the dome, wondering if these are 12.5?
Also would anyone know the volume of the dome cc's ?
take care

Hello
I was able to find the piston on the web, and by cross referencing with other domes, I have an idea of what it is for volume 30-32 cc
If anyone has an actual volume in cc's, please let me know
No, 87 pump gas for this. I hope I can get away with high test, but we will have to wait and see. I have a large cam which will help bleed off some of the compression
take care

Well, I bought some plaster of paris, got a piston and made a mold
I cc'd the valve notch as well on the piston (about 1 cc) and I will have 11.3:1 on my motor (GM/TRW pistons)
I have a really big cam 256/264 @ .050 for duration so it will bleed a lot of compression off, but I think I will have to either have a water or alcohol injection system
There are 3, E-85 stations in Ontario now, so hopefully they will be more soon
take care

Plenty of folks are already travelling / visiting / etc. so answers will be slow for the next while, Tom.

We'll be happy to see update photos when you get them.

Merry Christmas.
