Just saw the post Mark. I'm happy to hear everything arrived in good shape. Sounds like you did a great job on the rest of the assembly and install.
Good luck at the track!!
Thanks again,

They will work fine.
The choice nowadays seems to lean towards 243 (LS2/LS6) casting, since LS2 castings are cheap now (same casting as 243).
I got my 5.3's 1.5 years ago otherwise 243 would be my choice now.
You can get TSP stage 1 with dual springs for around $1200 or with 918's for around $1050 or so

Well after a pleasant long highway ride, the 500 miles are up. I changed the oild and went to 0W40 Mobil 1 Synth.
Oil pressure went up by around +/- 5>10 psi across. 5W30 was a bit thin for here when hot.
On the way back home, 35 miles stretch, I decided it is time to do a couple of little WOT bursts.
Not low speed but 70 mph punch.
So I nailed it, it downshifted to 3rd while my eyes were pivoting between oil pressure and my wideband guage. Oil was good but WOT A/F reading was a bit lean. I took it to 6300 and it was steady at 13.8, then I backed down right after shift to 4th.
I repeated this a couple of miles down and same reading. So between WOT 346 setup with nitrous tune at 12.5 A/F, now the motor was demanding more fuel. 1.3 leaner, so adding fuel is tomorow's job.
I was logging, still no KR but too lean for my taste at 11.7x SCR. Timing at WOT is 26* with 98 octane.
TR6 gapped .040 and .040 quench (squish) are doing their job though.

SVO 30 lbs (~36 lbs at 4 bar), Racetronix 255 PnP.
I was still running on my old 346 tune (same cam, same heads), so naturally I expected this.
Trick is the 346 tune was a nitrous tune so reduced timing (26*) and 12.5 A/F (rich)
On the 370 that translates into a lean tune, nothing to damage motor at short run, but nothing I would shoot nitrous on either
Also I either need to change my injectors, or converse my dry nitrous into a wet kit. Both options are in the same price range, I'll make a decision next month.

Yes, I do my tuning, but I didn't want to mess with it during beak in since part throttle was OK and I didn't go WOT untill today after finishing the magic 500 miles.
I'm no genius though, new to HPT. Since I had bought a mail order tune from Allen Nelson last year, he is kind enough to help with issues I have.
I kicked it in today to have an idea how much to add tomorow.
I have 62 psi/ 59 WOT ( Racetronix pump harness and Racetronix FPR at the rail), my 30's are no where near maxed at the moment. If they go over 80>85% after adjusting A/F then yeah, I'll change anyways.

glad to have u back Predator. looks like u got one hell of a setup there. give it a few months to cool off and post some numbers. by the way, did u buy it as a long block or did u add the top end? if u bought it as a long block, what did u pay?

So in essence, Predator has to tune his beast for basically the same type of fuel as we get here.

The CLC method is the average of RON and MON.

The info on the pump octane is correct, I believe it is actually 94 octane US standard. But 'll check to make sure.
But it is only 6.25 UAE Dirham a gallon, that is 1.69 $ US.
LS2 Bait, a CNC ported 5.3 is 64 cc on average and a CNC ported 243 is 64 cc on average. Same Same, better casting.
Orangeappeal, you suck too
BTW, added some fuel today for both WOT and part throttle. I have it at 12.8 WOT and the response is soo much better.
It pulls and pulls and pulls.
I think, I'll leave it at that until the weather cools off and I can do some dyno sessions.
Can you believe lighting up the tires from a 50 mph WOT
It never used to do that before.
