Hey guy's,I'm going crazy trying to choose a solid lifter cam for my currant 396 build.I have a 396 2 bolt w/ARP studs bored .060 over,063 oval port heads that will be fitted with bigger valves and ported,10.5 to 1 compression,and a eagle spec. 4340 crank and rods.Trans is a M22 w/ 3:73 gears out back.Comp cams recommended a XS274s,and Lunati said to go w/ a 40208.I read alot on the site about the lunati 402A1LUN also.I was hoping for a rough idle,and most of its life will be street use.Appreciate any help.

I just bought a cam from Ultradyne cams (now called Bullet cams). Call them at (662)893-5670, ask for their tech guy and have him help you decide on a cam for your application. They custom ground a cam for my application. I had called them on Tuesday with my car's specs.....and on Friday my cam arrived at my house! I am VERY pleased with their service. They are still a small enough company to actually care about your car and it's performance.

Go with the 402A2Lun

Here (http://www.holley.com/402A2LUN.asp) is the link for it. Real nice on 112 lsa, which will help street manners.

Just got off the phone with Bullet cams (Ultradyne) and couldn't be happier with the service.They recommended a custom grind - 284/292 @ .050 w/ 600"/625" lift.Couldn't believe the price was so reasonable either!!!

:eek: 284/292 @ .050 :eek: Are you sure that's right? That would be a tough one on the street.

A friend has a 69 with a 427 M-22 and 3.73s. It has the Lunati 40207. Great street idle and midrange but with the 2.20 low 4spd and 3.73s it not the greatest street combo. I would think your 396 would be worse the cam is 237 .050 in 247 .050 ex 110 sep and 108 int. CL.. I would think about going down from there not up (you sure you got the specs right)

I will second the "not so street freindly" comment. with that much cam, you will be smashing your head against the wall cursing the stupid 2.20 first gear in that muncie. I ran a comp 280H 230/230 @ .050 in a 396 with an M-22 and it was not too bad for stret manners w/ a 3.73 gear and 275/60 tire.

I'm pretty sure those are the specs he gave me,but I could of mistaken him.I'll call again tomarrow and double check.

I screwed up....The advetized duration is 284/292.Duration @ .050 is 251/259,lobe sep. 108,gross lift .600 intake and .625 exhaust.Do you guy's think I should step it down some more?

Imho, yes!

I'd go with the 402A2Lun that wildman mentioned earlier b/c you have a pretty small BB if you will consider it as such!

In fact, I went with no more than a good old CC 282S solid for my about 9.8 to 1 CR., 496 for midrange grunt.

Nothing fancy at all here!!
