Ma recommends long tubes or some type of header with the c2 cams to get the full benefits. Porting the heads on a stock short block isn’t going to yield you that much power. Seems like a waste if you referring to Hp to $$$ ratio. You’re better if porting the upper and getting a set of long tubes.

Blue line C1 cams
Red line C2 cams



Pretty good comparison as mostly same build on both pulls.
(Red pull was on block with proper pistons, blue pull had rattly, slightly too small pistons hence the rebuild with the C2s)

Similar hp
Slightly better low end torque with C2s

Do you have test pipes, stock cats, HF cats, or long tube headers?

Edit;

Z1 400 hp kit, and Stillen g3 long tube intakes, Berk CBE.

Also,(but likely unrelated) z1 built short block, ATI harmonic balancer, jet hot ceramic coated from headers to test pipes. Nismo oil pump. Uprev tune. Z1 lightweight clutch/flywheel (6mt) billet CSC. Z1 vented rotors... I think that’s all the stuff that might effect hp/ torque numbers, and none of changed between cam swaps except for tightening the clearances between pistons and cylinders a few thousandths.

I think the long tube refers to the G3 intake

my brain registered the previous question being about headers and didnt realize he answered about intakes

stillen does have a set of headers that are pretty much the exact shape/setup as the Z1 shorty headers. maybe thats why i went that way as well.

Mine is done now I just have to replace injectors to finish up tuning. It'll be kinda hard to compare it to anything because I'm running this with a 6870 turbo on a BP kit and 10:1 compression where most people go 9:1 .

I was thinking about doing a before and after dyno to see results but it's hard not to upgrade the internals with the engine pulled.

For anyone curious about whether it makes a difference in the sound or not, it does. Quite a bit, actually. It's no LS chop chop, but you can certainly tell the difference.

Congrats!

I heard in the video you have headers, test pipes, cbe, CAI w/ z1 upgrade, ported upper/lower intake manifolds. Anything else?

aftermarket diff, lightweight flywheel, rotors, etc?
