Default 408 is in, and about ready to start

Just waiting on some new Kooks LTs, then it's ready to fire up and get a nice n/a tune. Not really much to look at, if it don't make it faster then who cares, but will do some tricking out later in the looks dept. Man I am ready to roll and get to racing.

Here's the cam I choose, now I know it's not a mondo cam like some of ya run. But, that's because this is a true street/strip car with a manual. Anywho what do think, it's a hyd roller from Cam Motion:
228/232 .578/587 112/108
I think it's a decent nitrous freindly cam that'll work with my current mild LS6 heads, and 3-stage dry hit? Also, PRC dual springs.

Robert

Looking good Robert!

I am in the cam selection phase, waiting on the flow numbers. Likely 224/224 or maybe 224/228 on a 114, have to consider the wife drives it with out the bottle when I am at sea.

Got CajunDude Powdercoating some Nassau Blue Valve covers and Calipers as well.

Beer

Thanks for using a host who is not filtered by my company as well, usually I cannot see your photo's when offshore

Beer, the dual pattern cams can help on the exhaust side, which is a plus on the spray.

dude... that cam is tiny... i dont understand why you would go big cubes/iron block if you were planning on keeping it stealthy and throwing in a baby cam?

i drive my car every single day with no issues on my 250's cam... i really think your going to be dissappointed with the numbers that cam makes

I was hoping to see some of the "top secret" new dry set-up on there

Motor looks great. You'll beat Noyzee.. no problem.. cause he's going to take forever cleaning all that BLING BLING in his new motor, and miss the race.

exactly what i was thinking.... my cam is a fairly large cam when thinking of cams in general for the LSX community.. but with the bigger cubes and the notched pistons there was no reason not to go big.


honestly my car drives better with my big cam then my buddies 346 drives with his MS4... my daily driveability is not an issue whatsoever and it also gives you a nice lopey idle.

Well the one thing you guys are missing, I have stock LS6 heads. Putting a big cam in would be futile, don't you think. Now does the cam choice and specs seem out of place? Also, we have grid lock driving on the freeways; Furthermore, I plan on taking long trips to the mid west. Besides, I'll be putting down way more than the Z06 could use at this point, at least 700/700. Now with that said, this coming fall/winter I want to go with the l92/l76 and probably will bump the cam up at that time, and do some drivetrain upgrades.

You don't think a 112/108 will also give a nice lope?

the cam is fine. hell remember mamo's post of the GTO with the 220//224 pulling 450 rwhp on a mustang dyno? i did go bigger than you, in my 408. 232/240 117LSA

here's what it sounds like.

was that GTO a 408 cubic inch iron block???

btw robert i didnt realize you were running stock LS6 heads. that makes a little more sense. Why not send them over to gunnar @ patriot for a cheap and easy port job? LS6 heads are a very good starting point for port work. id bet you can get within 20-30 RWHP of the TFS and AFR heads (hell i did and mine are about the oldest patriots made) :Jest:

btw robert i drive my car in gridlock traffic on our freeways every day as well... big cams really are not that bad in a big cubed motor. its all in the tune i promise. i almost wish i would have went BIGGER lol.. just because this cams street manners in my motor/setup is so tame and calm i could stand some drivability issues because at this point honestly i have none.


i put down the 480 RWHP on my 408 with some old (first version) patriots with some hand blending and 3 bad valves that werent opening all the way.. LS6's properly matched can make some pretty good power even on the stock LS6 intake and TB

Sounds good, and with the idle down a little bit, I bet it's nasty sounding. This with a 117 lsa is great, I would think the 117 would really mellow the idle out, but it's sounds good to me. I am trying to keep mine quite also, running through stock cats. Have you got any times yet?

not yet. have about 1300 miles on it. i'll probably hit the track next month. i did a little pre testing. took on three motorcycles about 600cc. from 80-150, i couldn't lose them and they couldn't catch me. and this was on motor only. haven't wired in the nitrous, yet.

here's an underhood shot of it. i've done a little more to it since the initial install. i have a purge on each side of the fuel rails. i'll be using two "V" purge blocks like you have. i'll have four plumes out from the windshield.

I am saving the LS6 heads to go back on the original motor for resale time. i'll keep the 408? and maybe do a real race car, an f-body (did I say that out loud). Also, will be moving on to the C6 Z06 sometime in the near future, so the value of a low milage C5Zo6 in stock form will be more $$ for trade in.

Nice numbers you got, from the get go. You may be at the magic 500rwhp with the newer heads?
Robert
