I'm going to build an engine(350 .30 over) with SLP runners,TPIS Big mouth base,ported plenum, 52mm throttle body,and TFS 23 degree heads. I'm trying to decide on a cam, Hot cam or the TPIS ZZ9 cam.Which do you think would work better? Or do have any other suggestions?

91 Camaro Z/28 5.7
SLP catback
SLP runners
SLP 1 5/8" headers
TPIS airfoil
160 degree thermostat
Rebuilt 700R4(borg warner/raybestos clutches,Kevlar band,vette servo)
B&M 2400 stall torque converter
Paxton SN92

 

I've ben asking the same ? for 3 days and no answers yet same setup too. I'm thinking of going with traxions cam 218/224 498/502 with 112 LSA its a comp XP269

 

Hopefully some people will relpy this time.

 

The LT4 HOT cam is about 1/2 the price and better suited for modded TPI engines than the ZZ9 cam. The CompCams 218/224 on a 112 (or even a 114) LSA is also a good cam for the money (~$250). I went with the LT4 HOT cam in my 355 and really like the way it idles (a little lopey but not too rough) and runs. I'd have better times at the track if I wasn't having a serious detonation problem due to my >11:1 compression...
