A new, mild cam I need to get for my 402

The lift is what I'd try to keep down, so it's not a valvetrain hammer. a cam in the 240/244 duration with say around 590 lift on a 114 with some advance ground in with a 402 ci motor would probably be very streetable. The cubic inches swallow up alot of camshaft.

I did and no problems after 5k or so.
Choose a cam with 6 degrees or so of split. If you've got a good tuner go with a 112 lsa with 2-4 degrees of advance. If not go with a 114 lsa. As a rule of thumb a 402 will take 10 degrees more cam than a 346 to give you similar drivability. Example: A 224-230 in a 346 will drive about ike a 234-240 in a 402. I run a 234-240 112 +0 but that's with L92 heads at 11.4:1 compression. No reason though that that cam wouldn't work very well with your heads but with 4 degrees of advance. Whatever you do, don't over cam. Your heads won't keep up with it.

IMO, I'd just get a vindicator and put that in. Guys with 346's are making 480 rw with those, so it's probably safe to say it will work good in your 402. Or call Mikey @ rapid and get a dominator from him, that would probably get it done as well.

Nice, so i should make 500rwhp no problem with a FAST then? and it should be pretty mild in a 402? if so this sounds like good news to me... what are the cam specs?

The Vindicator cam is 240/244 112 lsa. If you are thinking of going with this cam, call Ron at Vengeance Racing and he can tell you more about it and how it would work in your 402 with heads. Also, there have been quite a few posts in the dyno section with this cam (can't remember if any were with a 402) but you should have some good hp and tq with the amount of cubes you have.

One thing I'm sure of is that bigger CI certainly makes a car with a big cam drive alot better then you'd think it would. When I used to drive mine around, it never bucked, never really surged or anything, gas mileage was crap but I blame the th400/4.10/5000+ rpm stall for more of that then the motor.

I've decided to go with the MS3 in my 402 build. 237/242 .603/.609" on a 112 LSA seems like it will be good in a 402. If you wait long enough I will have my car up and running hopefully very soon. I will let you all know how she does in the dyno section.

Thanks
I mean I was thinking of cams like MS3, MS4, vindicator. I still think theyre a bit large. I dunno maybe 236/240 with .595/.595 112 lsa something of this nature???
But Im sure your ms3 in the 402 will be great. I was gonna use my torquer 3, until I noticed teh damaged cam lobe? the #8 cyl exh lobe has a groove in it... can it still be used?
probably not, where can I get this cam re ground?

Problem wtih regrinding a cam is now you're on a smaller base circle and that can get hard on the lifters... I wouldn't do it.
If you regrind it, all the lobes really need to be done or you're ognna have one funky lenth pushrod, Probably not a good idea.
