This is what I am looking at for my valvetrain rebuild:

224/230 .610/.598 114 or 115 LSA

LS2 lifters and Patriot Gold springs

what ya think?

 

IMO too much intake duration and not enough lobe sep. Check into LS9 cam. I just installed one in a 09 GXP G8 and a TVS 1900. It is ridiculous. The higher intake duration may make more dyno power but the torque curve(seat of pants feel) might disappoint you. I took a similar cam out of my truck for this same reason 224/330 581/588 on a 114. The cam I now have in my sig makes tons more torque.

 

I hear Chris really liked the set up....

I have an LSA camshaft still sitting here............

 

and what are the specs on this a&a stage 3 and/or ls9 cam?

 

I agree...a 210/230 or even a 215/230 would be better, on a 116-118 LSA.

 

I've got a GT2-3 for sale

 

i had a gt-7 208/230 .5xx/.5xx 121 and i did not like it at all. it pulled pretty hard down low...dead in the mid range and OK up high.

then i went with a 224.228 .570/.570 114 and it was really good throughout the rpm range. felt good off and on boost


what are the specs on the LS9??????

 

LS9 cam 211/230 intake .56? exhaust .55? on 122.5 LSA. A&A stage III cam .218/.232 .562/.574 on 117 LSA.

 

having one built tomorrow. 224/230 .600/.600 115 or maybe 116...i have till tonight to decide on LSA.

Patriot Springs arrived yesterday from WCCH.
Lifters/trays at dealer waiting for me.

 

Will the LSA and LS9 cams work in the GENIII engines? Do they have the reluctor ground into the rear of the camshaft?
