Cam for Weber Carbs

gt4peterMember

I have old 48ida's and want to use them together with my 4v heads.
I did some portwork on the heads and intstalled fresh new manley valves.
Also the heads get some new springs and titanium retainers.
George P. writes a nice 2do list here in this forum. Thanks for it !
But now I do not know witch cam should I use.
I know from an old factory sponserd racer, that they use webbers for racing together with cams witch have extreme lifts.
He said something about 0.7 inch lift !
He said , when I install a cam like this , the car will run like hell.
Also he said , the webbers are not for the street. Only when you use most agressive cams , they start to work.
He also said that the old factory race engines start theire live at about 5000 rpm and often see more than 8000 rpm without any problem!
Only heat was a problem
Can this be true ?
Thanks
Peter
