Anyone run 1.7 rockers on Andrews 21 cams?

I'm like u I'm happy but allways wondered is there a holly grail of a cam out there to unlock tons of power. Last week I had my chance to ride 2 bikes that was the same year and model **** they were both even carb bikes Boy was I happy here's my chance to once and for all find this truth out. 1 bike was 95 inchs S&s 510 cams and S&s heads the bike sounds so mean so I tested the bike out and the owner was on my bike 95inch 9.3.1compression with ported polished heads and andrews 21 cam and my bike had more snap even the owner said mine ran better... 2 bike was 95 inch andrews 37 with Screamin eagle pro heads and it had a drop more power very little to fight over... After this I give up I'm leaving my bike alone... If u want a difference u have to go big like a 117 for hillside or something then u will have something...

I am not opposed to getting honey comb springs though if I need to.

Even our Stage I Heads come equipped with our proprietary progressive wound(beehive) springs that handle .590/.600 lift.
More info on them on our web site.

That 98"/Wood 6/head combo is one we've done here since 1999.
Works well!

Far better quieter cams for a 98 than a .510 lift woods 6...and you wont end up with a kamikaze torque curve.

So AV&V springs are a proprietary item ?

Anyone with a credit card can buy them from Goodson

We'd reccomend releases with that.
Big broad torque curve, with great fuel economy also.

It is very difficult to fix a bad combination

Looks like what you have is working but know also that there is ALOT more to be had within that 95" S&S combo you described.
