Achieving desired SS valve lift.....

ss wannabee · 07-14-2013, 06:59 AM

Guys, ALL solid advice by everyone....

Kevin...I realize this combo works with high rpm...and that the Jesel has been the norm
for many years....

Already have my roller rockers in ALL the popular sizes....some full sets...including
some rare 1.7 ratio that were made by Crane years ago...

There are some other aspects of my "build" that might seem a bit "old" to people....
don't want to get into them....but when I say "budget" I mean it in the truest sense...

I'm down on bucks...who isn't these days?. Stock Eliminator is NOT an option for
me...Tried that back in the OEM piston and camshaft spec days...didn't go too fast...
but learned a lot....

Don't agree with TODAYS Stock rules.....

The main reason I asked the question...is that some time ago...maybe just after the
SS cyl head porting rules change...there was an ad in Dragster by a major camshaft
company indicating some "new" SBC SS roller grinds....

The cams seemed "small"...with lobe lifts just over .400"....but the ad suggested to
run them with 1.7/1.8 ratios....hence the Jesel...which I don't have anyway...

Realize that ad is probably about 20 years old now...maybe not relevant information
today? Heads being done differently, etc?

I have some older cams...in that neighborhood...probably obsolete today...but thought I
had a chance to make use of them....I'm run them anyway...with the lower ratios and see
what happens....

Just was wondering if racers favored getting the valve lift THAT way...for whatever
reason...I guess physics comes into play here....

Bottom line is it's taking too long to complete this car....many obstacles along the way...

Enough of this sob story...as they've said in the Army..."BETTER to do something NOW
and TALK about it LATER!!"

Onward!!!!
