427 build Darton sleeved block. LS2 dry sleeve.4" stroke and 4.125 bore.
Manley rotating assembly.
10.8:1
LS3 heads and LS3 intake. 1.875 long tube headers.
Car is 2900 lbs. 3.50 gears. Built 4L60E. 3200 Yank stall converter.
Local LS builder suggests a cam with Intake 230 and 239 exhaust. .610 on intake and .540 on exhaust.113 lobe center.
Does the .540 seem a bit low?
This car will be a street driver. No power adders.
Would like some opinions.

67 Nova is the car.
Trying to do somewhat of a budget build. Had the LS3 stuff. Build the bottom end so I don't have to mess with it. Top end stuff can I change or improve as time and cash allows.
My real question was on the cam specs. Haven't bought anything yet just wodering about the .540 on the exhaust lift.
Thanks

I should of said stock LS3 intake and heads.
Cam wise I was thinking 230I/235E about .610 lift on intake and exhaust. 114 C/L. I know it seems mild but again as I mprove stuff like heads and intake I can move up to a bigger cam.

This guy has done a ton of R&D with L92/LS3 heads over a couple of years. From 403 to 427. Stock heads, WCCH Stage 2 and 3 heads. Multiple CR's, cams, etc. etc. etc....
