Best Cam for 427 small block?
You can see from my sig that my current cam is a XE-282-HR. The specs @ .05 are 230/236 and .510/.520. I am installing a set of AFR 210's that have been Competition ported. They have better flow numbers than the Dart 215's. I have a recommendation from Crane and Comp Cam but I would like to get some forum input as well. The car is a weekend driver that will see some strip time.

Im running a Comp cams solid roller in my 427sb with dart pro 1 230s
Lift .616/.622
@.50 248/254
Lsa 112
small base circle
theirs a slight lope to it , not what im use too,and the vacumn is good too .
I might try something a little more radical later,other than that the engine just gets it.
If you want a cam that has good idle and vac this is the one.

I have a 236 degree @.050, 108lsa .507 lift cam in my 434.
Puts me at about 12.90 in the 1/4. Prolly needs tuning for another 2-3 tenths...
Vetteaddic;
Do you have track times with that engine?

No track time yet or dyno,Id like to find out myself what hp is ,Im afraid of going to the track and leaving my rearend there,
I have done nothing to the rearend except carbon fiber halfshafts ,offset t/a .
My next motor will be a 434 ,is that a 4.155 bore x4.00,I wonder if i can get a bigger bore,4.165 or 4.185

Put a solid roller in there, I have the Comp Cams XR280R in my 406ci and I love it, specs are in my sig. It shakes real nice at idle, you could go 1 or 2 sizes bigger

Thanks for the input!! The folks at Crane and Comp Cams recommended the folllowing hydrolic rollers:
240/248 @ .05 .558/.558 110 LSA & 105 intake centerline
248/254 @ .05 .599/.619 110 LSA
What would be the benfit of going with solid rollers instead of hydrolic?
I have read that solid rollers have lubrication problems when used in street applications.
