Potential N/A setup I've posted about it before, I got a dyno appointment coming up soon w/the blower setup, I'm having some minor issues with it, but nothing major that should stop it.....
If all goes well I'm hoping for 650rwhp and 650rwtq.....
If all goes well....
If not I'm selling my blower stuff, heads/cam, injectors, etc, and going back to N/A with a spray setup....
Motor will stay the same, I will be putting on Stage II LS6 patriot heads, a 240/250 .610/.620 112lsa cam, and I'll probably have the timing setup for a 200shot....
Anyone have a setup like this? what kind of power are you making, et's, etc...
all my other mods are in the sig......

I wish you the best with your results. If you go back to NA and don't change the motor it will be a dog, low compression, no cam you'll at least need a piston change and new cam.
Good luck

my only concern would be running the milled head, with a smaller/thinner gasket to achieve your desired compression ratioi and would it have enough P to V clearance to run that large of a cam?

The pistons have reliefs in them, I'm sure I would be able to get away with something close to that.....but your right depending on how much the heads are milled, I'll get it all speced out if necessary, I've had to get this backup plan ready before....
BOS im currently running PP LS6 59cc heads on a Speed Inc build forged 348. Havent gotten any dyno numbers yet as ive had some vibrations issues that the guys at Speed Inc are trying to sort out. But I should have some numbers in a week or so. Im running a G5X3 on 114 LSA with a direct port nitrous LS6 intake. Im planning on spray up to a 300 shot but havent got any of the N20 stuff taken care of yet as im still getting the motor sorted out. Maybe if you decide to go the N20 route we can help each other along.

I like Patriot heads, but take them for what they are worth. To me, they are a budget head. If you want the best (given you are spraying 200+), Id go for TEA's Judson Massingill heads with Brian's "hand finishing" and "nitrous exhaust port." I guess they are considered stage 2.5 heads. They will probably flow 330 with an LS6 core and 4.03 bore. I think he can run these on 6.0 heads too if you wanted to save some cash. However, I would mess around any more. If this IS a big change from FI to NA/N2O...do it right ONE time.
Oh, and have some spec your cam for you (ESP, TEA, etc.). Look at TEA's vette. It RUNS!

The chamers are already expanded to 73cc, would it be a mess to weld down?
I was going to get the judson series a while back for a blower style head, how much are those 2.5 stage heads ? That could be a possible option because I'm sure I'll have some $ to work with....
Also, I'm going to do a F.A.S.T. intake if this does occur.......and then when I add the kit I'll most likely work it through there, any real benefits from 78 to 90mm?

For that big of a shot the hand finished heads w/ exhaust port should be worth it. My Judson TEA heads are done but waiting for a few days before I get them sent to me and installed. I'll have dyno #'s on a 200 shot within a month. Talk to them about getting a set....they always hook up repeat customers.

I would say the 78mm fast is worth close to nothing on a 370 (maybe 5rw?). The 90mm has had good results (10-15rw on 346's w/ good heads/cam). Like I said, given all the BS you are going through with the ATI...I'd go all out this time...one shot...one kill...no excuses. TEA 2.5's, 90mm LSX, Good cam (let TEA or ESP spec it..or MTI, SPeed Inc, etc.), and a NOSzle or DP. NXL is 'ok' from what I've seen, but I guess for just 200, you could use a dual nozzle setup pre TB.
Verb's. Judson's last name is spelled Massingill as far as I know. Also...what is "HFCL"? Hand-Finished-?-?

BIGBOS be careful milling too much with a head that sees a lot of spray. You want to keep things as thick as possible
One good thing is you have lots of choices at this point

hell i dunno. I think Brian ran the car on the dyno with the new heads (up 90rw from the 1.5's) and then broke the input shaft? of his 4L60 the first time to the track. doubt he was running NA on that run.
TEA?? Are you reading this?

Any info on how much these Judson heads are.......
I'm sure I can get a buyer for my current TEA's, they are a popular choice for blower guys and are almost brand new......
90mm FAST it is, along w/the TB
How is the TNT direct port kit? That or NOSzle

I e-mailed TEA about the situation, the thing I don't think will work out is the fact that the heads are 6.0L, I need to get my Compression UP.....from its current 9:1 position, Speed Inc. (local shop that does all my work) came up with a way to get around this before, I think a thinner head gasket and some milled heads solved it, but I'll wait and see what Brian@TEA has to say
