Wondered if anyone has experience with these.
I am considering using an Aurora 4000 on my 89, using eighter stg4 ddps or 5x14 or something like that.Hope is to make 350-420RWHP on #2.
Have 2nd gen IC fitted.
And I can`t find the size on the 4000, think its 63/76/? or something.Will it be too slow/big?
Or should I rather go for a 62 phat shaft instead?
