Scott,
In the early 80's I dropped a valve and it put some nice dents in the
top of the piston. I just rebuilt the head and got another 15 or more
years of driving. It was still running strong when I rebuilt in 2000.
If your BN4 is an early model (2639cc) it will have clamp type rods and
pistons for these rods can be hard to find depending on bore needed. I
had to change over to the 3000 bush type rods and pistons.
FWIW,
Don
57' BN4

Bad news. Was trying to get my BN4 that has been setting for years to
start
and noticed a stuck valve. Thought maybe get here running and a temp
cycle
will free it up. Then noticed a bent pushrod and thought might as well
pull the
head. Did that and noticed the No 1 and 6 pistons are burned. Just a
little
at the edge.(I will post some pictures tomorrow). So it looks like I am
going
to need some advice.I am thinking about changing the pistons, with the
engine
in the car. My questions:
1. Am I crazy not to pull the lump and completely rebuild?
2. Who is the list favorite piston supplier currently?
3 No lead head? Yea or nay.
4 Wasn't there a guy rebuilding rocker assemblies? Need contact info
Sorry to bomb the list but I couldn't figure out how to search the
archives
Thanks Scott
