Pontiac Automotive urban legends.
Where are you people getting your info?
HWYSTR455: I doubt you put 220K on a set of solid roller springs and make any power. I doubt you put 30k on a set.
I have them in SBC strokers. BBC street engines. Pontiacs, 572 cu.in BBC Merlin Jet boat. Thousands of Offshore marine engines use them. All aftermarket and running strong.
I give up. This is like the aluminum heads topics of the 90's when Pontiac people trashed the E-head when it was coming out. The posts are out there. I guess Pontiac people just want to keep their heads in the sand. Not my deal.
But people, don't trash or make statements about what you haven't messed with.
I'll be at VMP end of the month, driving my cart around in the pits watching all the Pontiac racers checking their lash over the weekend or **relaxing** between passes.
Just finished gasket matching & porting the CV-1 Intake. Stop by and take a look at the NEW Canted Valve CV-1 heads with a hyd roller, running I hope into the 9's on 93 octane pump gas.
