Well, I've made my decision (impaired by funding as usual ), but this is the combo that I'm going with after my LS1 took a crap at the track last month (# 5 & 7 cyl gone)

6.0L iron block (370 CID)
4.030 bore
Wiseco flat top pistons 2.2 cc valve relief.
Callies 6.125 con rods
ARP rod bolts

Heads will carry over with my PRC 5.3L stage 2.5 (2/04 int/1.575 exht), 60 cc
MLS (GM) gaskets
Cam: TSP Torquer V2, 232/234, .595/.598 113+2

SCR ~ 11.45 and DCR ~ 8.58 (depends on piston/deck position)

I think this combo should make over 400 rwtrq and ~ 440 range rwhp (more would be welcome )

The reason I went this way was to maximise the use of my existing components salvaged from my last motor and the fact that this will handle 200+ gas shots very safely.

I chose LME to build the shortblock since they do top notch work and they offered me a deal (parts for $$) I couldn't refuse.

Now the dreaded wait.

 

Good luck with your new setup.

 

Sounds like she'll handle the juice well. plus keeping the stock stroke should let the motor play well up high. Do you have an adjustable timing chain? Maybe you could take those 2 degree advance out of your cam and run it straight up to bring the peak back up higher to counteract the added cubes. Just food for thought.

 

damn its gonna roll hard..

 

Actualy it is on 113+0 but i'm gonna advance it 2*
113+0 would be a 49 IVC
113+2 would be 47 IVC and would benefit bottom trq a little better IMO + it will make it a little exhaust biased for the juice.

if it doesn't work the way want, well I'll tear it down and run it straight, but i think it will do well.
It will still peak around 6300 and I want to shift at 6600.

I'm sure this cam will do better in the 370 than the 346 I had.

 

Im running the 112 +2 and I peak exactly at 6300 in my stock 346, shifting at 6600 to 6700. I would have thought youd come down in rpm with the extra cubes. I wouldnt think the extra degree of lsa would make enough difference to keep it up there. I like the idea of the extra torque for a street car, but I guess youll have to see how it affects your powerband up top on your track monster, especially being out of square. I have a sneeking suspicion youll be ordering a bigger cam with some added exhaust duration after this season. But for now, ill bet the low end is going to be monsterous! Shredding tires at will...

In a 346 the 113+0 was lacking a bit of the bottom trq due to the 50 EVO with the SCR/DCR I had it on (10.70/7.90)
Now this is raised to (11.45/8.58) so bottom trq for which this cam is supposed to be designed will finally wake up.
I has been experienced that anything over 42/43 IVC on 346 will peak at 6300 and no further (Induction restraint).
With the added 24 cubes, a 47 IVC on a 370 ci will still peak at 6300, EVO at 52 (should be good for trq), but then it brings the EVC to just 2* of TDC (still carrying the power well but shifting that band slightly lower in rpms)

At least theoreticaly this is the way i see it. Now it might not be the "Ideal" cam for this motor, but I'm pretty confident it will be a "strong contender".

 

I think you'll hit your 440/400 no problem. That'll be a solid machine when its all installed. congrats

 

Damn, I have basically an identical setup and was thinking of adding a little spray. My concern was piston life and now you put me back in my place.

 

"The dice have been rolled" is what your title should say.

 

out of curiosity, what timing set are you going to use when you advance the cam?

 

I think you will make quite a bit more than 440/400. Im thinking at least 460/420....

 

Out of curiosity, how much is gas there?

 

Cloyes

Well it was kinda my fault,
1- I was tuned for 150 shot and because I was about to loose to someone I couldn't loose to, I activated the second stage.
2- 200 dry on stock piston with 30 lbs SVO's is not a smart thing.
3- My nitrous pressure was too high and it spiked lean , AFR jumped from 12.8 > 15+ then (kaboom)

You can spray safely but you have to admit I pushed the limits there.

$1.65 for 98 octane / gallon

That would be nice,
I should get a 90/90, but I want to get one that is plumbed for DP and those are expensive, otherwise my 80/80 is working fine.

 

I almost max out my SVO 30's NA. You are definitely right about maxing the injectors with that 200 shot. Can you ship gas back to the states? Need a roomate?

 

Man if it wasn't for the Job, I would run back home to Tx in a jiffy.
Dubai is nice but the heat, dust, etc.... can get to you after awhile.
On the other hand, no income tax, gas is cheap, 1 drag track, and Jack D. is available

 

I paid 3.45 for 93 octane yesterday here in Houston....Soon it may be more economical to run some of that tennessee "white lightning" in the tank.

 

FYI, in Brasil the cars run only a 7% petrol and 93% ethanol (sugar cane alcohol).
Gas mileage not as good but power can still be there.
We will adapt
