Who to talk to at Comp Cams re custom cam

Tex013 · 02-21-2016, 08:29 PM

Hi ,
I know this isn't class racing but the motor/car is similar .
I thought it was listed a while back but who would be best to talk to at Comp re a custom cam ? This is for a 1962 Belair my friend bracket races - it runs a 409W motor stroked out to 489ci with a Mickey Thomson cross ram intake .
It is lift , valve clearance , limited so I was thinking along the line of a SS type cam . Lower lift but more duration , maybe 268/270@050 max .575 lift . Most shelf cams seem to go huge lift , plus 600 .
Please no referrals to Aubrey .
thanks in advance ,
Tex

Just in case you don't know, lift isn't where piston/valve clearance issue come from,piston/valves are closest right around 10*BTDC and 10*ATDC +/- a few*,no where near max lift. W engine could have intake valve to block clearance issues with enough lift and big enough valve diameter though.
Duration,centerline,lobe sepration and how aggressive lobe is, are the factors that effect piston/valve.
