i recently blew a head gasket or cracked a head. not sure yet. anyways, i'm taking the 882 350 heads off my l69 and putting the 416s back on. i'll drop the boost from my 9psi pulley back to 4 or 5. I plan to use a thicker head gasket, maybe getting my cr closer to 9 instead of 9.5 with the 416s. Anyways, what would be a good cam for this combo since i'm already going to be back down this far in. didn't cam it the first time due to lack of cash.

 

What's your induction? How is this supercharged? ie, blow-through carb, etc?

I'd lean towards a mild cam with a long overlap, like an FI friendly style. Those are good for forced induction. Comp has a lineup of cams for blown applications, but stay mild, you don't want to lose your bottom end, and a 305 is easy to overcam.

 

I'm not a forced induction guy so take this FWIW. But don't they like longer LSA and less overlap?

Too bad you aren't closer I have been wanting to port a set of 416's for a turbo build. You could easily get the chambers to +60cc and decrease detonation at the same time.

882's cracking? Who would have thunk it? (where's the sarcasm button when you need it?)

 

The forced induction is a b&m 144 7rib roots style blower. i have a holley 670 avenger setting on top which i believe is ample enough to feed this motor. it has longtubes and a 2.5 inch y into a 3 single, then splits into two out the back again. with the 416s i use to spin the motor to 6k at the strip for rpms purposes. the car is actually a daily driver so i'm not looking to loose my power breaks due to a giant cam. car makes 20 vac at idle. tranny is a t5

 

just checked cam and lifter sets on summitracing.com I went through the options and saw a superchanger option under the camshafts. for $100 i can get the sum-k1104 which was the smallest available of the options. lift int/exh .465 114lsa int/exh 224 and advertised was 282 int/exh i believe. can't post links or have multiple screens open, using my phone.

 

i think i settled on this cam
isky-201264-27112
basic op range 2000-6000rpms
int. 214/exh 221
advertised int 264/exh 270
int lift .450 exh lift .465

any better recommendations?

 

Ivelostcontact if you want I can run these cams through DD and see which power curves you like for your application.

Also you may want to try posting in the forum for power adders I don't think those guys get out much.

 

running them through a dyno sim would be awesome. i'll repost this thread in power adders. thank you!

the other cam i'm looking at is
int 215/exh 225
advertised int 268/270
lsa 112
lift .450/.465
