There is no definitive LS1 except the original and the one fitted to the C5 Corvette was the ultimate sample. The LS6 came in two different specs... the ultimate developing some 405hp and 400lb-ft of torque.
Yea but the changes were to all LS1's used in both the F-body and C5 and despite the changes GM still rated the LS1 in the C5 at 350hp in '01-'02 although torque rose from 350 to 375 ft/lbs.

Did he ever run it down the 'ol 1320?

Now that you mention it, it would be good to know what MPH the Camaros were running. It doesn't matter about the time so much (or dyno number), but the MPH is a good indicator of potential track time.

e.g.

104 mph is typical of what 300 hp cars were capable of.

109 mph is more indicative of the 350 hp cars.

Yes he did. I think he ran like a 14.8. Let's just say he wasn't an expert with a third pedal. But on the next run, he let a friend take it, (a Mustang guy ) who did much better.

Somehow, 13.30 sticks in my memory.

Do you mean 1.43kw (or hp) more in 4th than 3rd?

No I meant gear ratio, 1:43 (3rd) to 1:1 (4th). I think the difference was like 8 rwkw on the dyno (258 rwkw (3rd) vs 266 rwkw (4th)).

Don't forget, our dynos are different to the US spec ones.

Not all our dynos are the same anyway. 258 versus 266 could be due to the extra gear used in 3rd. And/or maybe a little run-to-run variation.

I can only speak for mine. But 106-107mph for the 6-speed SS from 305 rwhp stock and 104-105 mph for the A4 Z28 from 286 rwhp stock.

I reasoned at the time that it might have been due to the lower 3rd gear actually slipping on the dyno's roller slightly... but I'm also aware the discrepancy could have been due to a myriad of reasons.

Anyway, I think it's fun speculating while we wait for the real test(s). Ford haven't had a decent V8 for decades. It looks like now they have. It's all good.

All that other junk aside, how does a different block provide less parasitic losses and thus gain 20 hp?

1fastdog...looking less and less likely, unfortunately. Only possible day is tomorrow.

I thought that it was pretty well known that the LS6 block had windows in the mains. The "350hp" LS1 also had the LS6 intake manifold that flowed more air, but a slightly shorter duration camshaft from the truck engines.

Its pretty well known on this site that those with the ls6 block did not get any power increase. Do a search and you will find that this has been brought up many times.

No they did not. My 2001 z28 dynoed 312 rwhp.

I trapped 109 in my bone stock 01

Over the 98-02 years you had changes in intake, cam, exhaust manifolds and heads. My 99 Z28 auto ran 101.80 for its fastest trap stock. My 01 WS6 M6 ran 109.46mph trap stock (unusually high for a stock LS1). There were huge variences of the same type of car in the same year. But the later versions were stronger overall when compared to the 98-99.
