Hello,building street 440 looking at at cams,alot of choices,motor going in 1966 Belvedere,391 gears,auto,452 heads,street dominator intake,2600 to 2800 converter,750 carb.headers,msd ignition.The cam I was told I need is duration .05" int. 224 exh. 234
sae duration 298 309
lobe centers 107 117
lash hyd
gross lift .455 .488 cam lift 310 .325 good or bad?I want to hear and feel it!!

The specs on that cam just don't sound right. 224/234 works out to 260ish-270ish advertised duration, definetely not 298/309. A Lunati 60303 I think would be what your looking for with the net specs. A 60304 would be even better IMO.

A stockish build with a 2600-2800 converter, I would look at the Lunati 60302 or the 60303.

Go with the Lunati 60304. 513/533. Excellent street maners and makes a ton of power. Likes a 2800 stall.

should run good as long as that's not and EDDY 750.
