[V8Vairs] Perfect Engine for V-8 Corvair

[Ken Hand]

Anyway, I will soon have a 390 hp/380 ft-lbs torque (or there abouts) 327  
o put in my car.  I will run a 3.55 posi.  It will be used for  vintage 
acing (no clutch dumping, no speed shifting).

UMMM, yeah, right.

nteresting thread.......   I have wondered about the spinning  tires 
hing; if they are good and wide tires, if there is hop, wouldn't there be  
oading and unloading?  Which I always thought would be a bad thing  (similar 
ssue if speed shifting)?  I had assumed (maybe wrongly) that the  skinner, 
ess sticky older tires were one of the secrets to trannys and  differentials 
iving.

nyway, I will soon have a 390 hp/380 ft-lbs torque (or there abouts) 327  
o put in my car.  I will run a 3.55 posi.  It will be used for  vintage 
acing (no clutch dumping, no speed shifting).  The sweet spot for  the cam 
EX284H comp cam) is from 2500 to 6800 rpms.  

he old engine was a tired 327, (no idea how many years/miles on it) but  
he 3.27 open differential then used held together (bot the 3.27 and the 3.55 
have the 2 extra spider gears).

ight it be a good idea to  over inflate the rear tires a bit in an effort 
o save the R/P?  I  added a couple of extra psi on the day my car was 
ested and  glad I did.  The car came back with its tongue hanging out but the  
ifferential stayed together which was really my goal.
Bob,  CIDCO, Anderson said the 3.55 is the strongest ratio overall, 3.08 
as the  weakest pinion gear and the 3.89 has the weakest ring gear. If I 
ecall  correctly, Frank pealed the teeth off a 3.89 ring gear.
The whole  question of the "perfect" engine is really all about what is the 
trongest  engine that has best chance of being contained by the transaxles 
e each have  and how do we apply power, with abandon or with deliberation. 
Rick's  "get it moving before nailing it" style is what I always want to 
o  although I'm not always successful.  I've smelled rubber, another feature 
enjoyed by those who don't have an engine cover, maybe a dozen times or  
o.
I have always thought that an open diff is better than a posi  for our 
ars.  Getting on wheel spinning must put less strain on the  R/P.  (I could 
lso be wrong.)  Currently I have a 3.55, 4 spider,  open diff.  
As for the perfect engine for my situation, I'm  leaning toward a warmed 
02 or a mild 350 but may end up with what's in it  now.
The never ending story  continues....
