Hello....My 1975 Chevelle, work in progress . One off the first changes
was the engine over to a 406 sbc..... which the bottom end off this
engine is  ( STOCK )  I used all the original Rotating assembly...I had to
Straighten the cylinders as they were worn...Putting back in for Pistons
was the factory Replacement Cast Dished Pistons /  9.00 compression /
5.700 rod lenght / 4.155 bore / 3.750 stroke ...So shes stock...after this
I needed a Top end kit doing So I find this Sbc Top end kit on Ebay
which cought my eye....I called Bryan Fields and He helped me out a
great deal....as he recommended the top end kit that I needed.... and If
you no anything about engines its all in the top end that makes the
power ...So what  Bryan recommened I was able to pull out some
torque at 5100 rpm at 32 dergee timing..... and there is more power
there also at 36 to 38 degree timing ....but I had to come to reality as
the bottom end is STOCK and afraid off Melting my Cast pistons.....I
decided for the efficient Hp and torq......Bryan I thankyou once again
For the Great engine package and all your help then and now
....CHEERS from your new friend in Canada....Andrew
