[Alpines] Alpine pistons

[PApple16 at aol.com]

years ago, I used custom made "johns racing pistons"  can;t remember  where 
I got them, but they were not to outrageous at the time. I did get a  
little out of hand, and went with 11 to 1 compression ratio with large relieves  
in the pistons for valve clearance. Wow what a difference in the performance 
 well worth the effort, an Alpine that WILL get out of its own way
 
I might of gotten them from tiger tom down south, I will look around to see 
 if I can figure out where I got them

Hi,A few  years back, about five, I rebuilt my Sunbeam Alpine 1725cc 
engine. I
had to  bore it out to .040 over and I used some pistons purchased from
Victoria  British. They did not look like any other pistons that I have ever
seen,  and I have see quite a few, as they had a slot down the camshaft  
side
rather then the usual four holes up near the oil ring groove. I  expected a 
bit
of oil use after the overhaul, but it kept getting worse and  worse, not
better, to the point that I was laying down a blue cloud as I  drove; it 
sure
kept people from following to close! Last fall I pulled the  engine apart 
and
discovered that all of the pistons had broken skirts and  the oil rings did 
not
appear to expand as I had expected (photo at

Further the oil pressure pegged and  ruined the pressure gauge! So the
questions are: Where do I find better  quality .040 pistons? and does anyone
have a working oil pressure relief  valve which will fit a 1725 cc Alpine
engine (I have not checked it out  yet, perhaps a cleaning is all I need)?
