Default NEW Competition Camshaft

Thumper Performance Competition Camshaft !
.423-258*/ .338-218* HR 8000 Rev asphalt Ripping
(10.74mm / 9.85mm)

We have a great Full on STREET/TRACK Grind Camshaft !!
The Design is made for complete adjust-ability of a Performance
Camshaft with the Clearance restrictions on the R50/52/53
Cylinder Head !!

Spec is a huge .258 intake Lobe lift, making the advertised lift at the valve in at .423" !!
Throw in there the longer Duration number of 258* ( advertised) or 212* actual @ .050,
getting the AIR in at REV, is NO PROBLEM !!

Now the Tricky part... The Exhaust Lift!! There is a pesky Spark Plug tube in the way !!
We did it by reducing the base circle on the Camshaft ( intake and exhaust ) !
Our Camshaft has a Exhaust Lobe of .270" lift , or an advertised Exhaust lift of .388 " !!
And we set the advertised duration in 264* , or actual at 218* @ .050 .

Special assoc. parts are needed for this camshaft. Contact Thumper460@hotmail
for more info !! Thumper Performance @ Facebook
