So here it is....I am putting a 383 together, street car, fun weekend warrior

Compression is around 10.5 to 1.
Heads are GMPP Fastburn Vortec aluminum heads with 2" intake and 1.55" exhaust valves. Based on my research these heads flow around 250-260 CFM intake and 180-190 CFM at around .550 lift.
Intake is Vortec Perfromer RPM
Planning on Holley Terminator 4BBL
Manual transmission - 4 or 6 spd.
3.73 gears
81 Malibu 2 dr
Manual brakes

Engine has all forged rotating assembly capable of 7000 rpm

I don't mind a solid cam

I have followed David Vizard's cam selection and came up with the following specs:

cam 1: 106LSA, 288 intake 296 exhaust advertised duration, 0.550 int./0.570 exh
cam 2: 106LSA, 285 intake 295 exhaust advertised duration, 0.532 int./0.555 exh.
cam 3: 106LSA, 300 intake 308 exhaust advertised duration, 0.516 int./0.525 exh. - already have this one

What do you guys think ?
Fill out Mike Jones cam recommendation sheet at Jones cams, or call him. He can regrind your existing cam too.
I would add, pay for the pressed on cast distributor gear. Wearing out distributor gears is not fun for a car that will see a lot of street use and miles between rebuilds. It's worth the extra money for piece of mind.
