I've gotten fantastic results with Reed Camshafts, but I keep thinking about the IMCA "claimers". I'll bet those guys aren't spending the kind of loot on a cam that I am! 355 two bbl 3300lb turns around 6500--sound like an IMCA? Anyone got a "cheepie" cam that WOW's ya?

Heck, even OUR custom “shelf” stuff gets some fine tuning for single-track racers after the first season in many cases…especially hydraulics.
Rules, restrictions & track layouts/designs are so varied in circletrack racing…shelf grinds that work are very difficult to do…obviously much more has been done from all cam grinders on the Chevy/Ford fronts so there are bound to be good’ns out there…knowing what to look for is the tricky part…and too many folks…racers and manufacturers alike…spend too much time & money looking for dyno power…race power is typically overlooked…and mostly comes down to working within restrictions rather than against them…knowing what makes a motor “happy” sure does help too…but it all comes at a cost if you’re gonna do it right and in most cases the extra hundred bucks for something more “custom” is very well worth it…we’re in the middle of testing a boatload of cheap hp grinds for Mopar motors to see what may work “best” for a claimer type line…but most of em are the same few grinds from several companies…so we may scrap the deal and go with some well proven mid-priced pieces…we’ll see…

SPEEDWAY SELLS SOME TIGHTLASH, I HAVE TRIED THEM ALL IN A 13-1 355, I LIKE THE 2ND TO SMALLEST ONE BEST, I THINK ITS 248-252 DURATION, I DONT HAVE MY BOOK AVAILABLE.

TURNED 62-6400 VERY WELL. LOTS OF POWER.

You're exactly right rascal also a lot of people think that the high lifts with all the big #s are better not always true need to talk to a pro when it comes to cams and have all your info at hand the more you can tell him the more he can help you

A lot of times its seem to me that bigger numbers somehow relate to bigger numbers of rpms. IMO talk to a tech guy at either speedway, jr, or midwest. Tell 'em what your runnin and on what size track and they may have some good recommendations.
