<VV> Re: TURBO ENGINE KNOCK

[N2VZD at aol.com]

my many years of running a 64 spyder with 63 turbo heads (put compression  
too high for casual street use)  was hours of trying different things.  carb 
issues do not apply here, i had several mods to rods and jets etc that helped 
other issues. i ended up with cd ignition(big difference..now remember , this is 
back in early 70's before a lot of choices on electronics) recurving the 
distrib to dump in advance quicker but stay about the same amount, and i had to add 
additives to sunocos best gas. once in a while i got some av gas  or unico 
racing stuff from race track guys. the reason i converted that car to 110 
powerglide was to be able to travel all over and caravan without issues. but boy i 
miss it when i want to feel power when stepped on..it would pin the boost gauge 
.. and on a cool day look out!
start with trying it with one spring removed from mechanical advance, run 
electronic ignition with hi output coil and darn good wires etc(seths wires?) or 
spend real money and try a dale unit. the higher compression was nice because 
it ran like a 110 or better at low end and boost came in sooner but i was 
always worried in warm/hot weather about that knock.
