Howdy,
Well, after 12 years I need to freshen up the motor in our GN. I was looking over the current Hyd roller cam, and it is starting to wear on the nose of #1 intake and exhaust, so I need to come up with a new camshaft.
I haven't been keeping tabs on what curent "hot ticket" is with regard to Hyd roller cams and wanted to see what the current recommendations were in the Buick community. Most of the cams I have seen seem to be more optimzied for stock iron heads with more exhaust lobe to crutch the stock exhaust.
Are people seeing gains with the bigger exhaust on a good set of heads?
The current cam is a ATR RP309G which is an old Crane grind.
212/206 .497/.482 109 LSA
mods on the car are
109 block with billet caps and loveridge girdle
ported GN1's
BGC intake
70MM accufab TB
72# inj
Front mount IC
Precision 3500
ATR headers
Terry Houston Down pipe
TE63e turbo
