Calling all HOT CAM owners..
I'm thinking of this cam for my new motor.. lt-1 intake, very ported 882's, full exhaust, other little stuff...
What kind of power and times were you guys seeing with this cam?

My best time has been a 11.96 and fastest was 115.81 mph. (not in the same run). I hope to get better when I get the tuning issue straightened out. I have ported heads, headers, hotcam, electric water pump. EM headers without cats going into the stock exhaust, 4.09 gears, 3000 stall converter, and ET Streets 27x11x17. Still running the orig, injectors, 48mm tb, and as said above stock exhaust.
I dynoed at 355 hp at the rear wheels with a ed wright generic chip.

Best with the cam in a stock LT4 bottom end motor with ported heads/intake, 52mmtb, Longtubes, corsa cat back, 4:10 gears and drag radials, was 11:82@118 in ideal weather/track conditions.

do you guys think that lt1's got faster as the years went on. say if I had a 1996 vs a 92 or 93?
what type of porting or heads are yall running I just bought my hot cam kit...325 shipped new
.
and I have stock lt1 heads.
I also might be getting dana 44 and 3.73s. but I am worknig on a cheap deal.
so with stock rear end and stock heads.
what are my 1/4 times most likely going to be?
my goal is mid to low 12s after dana 44
thanks your friend

The 92 was absolutely the heaviest LT1 Vette, they got slightly lighter throughout the years. Any difference in performance can be attributed to that more than the engine, even then it's almost negligable unless you're a perfect driver.
As for power with any given stage of modification, check out the link to my website above. For an auto trans subtract about 20 hp off of each peak.

Many many dyno charts have proven that the LT1 no matter what the year is very consistent with it's power output. Any of the year differences go out the window as soon as you replace the cam and heads, then they're all on the exact same playing field as far as power goes.

i dropped well over 100 lbs! also the spare tire jack...if you are counting ounces.

yes well I have that 2x60 AC. (2 windows down at 60 mph)
also this is not a daily driver!
I'm building a speed demon... I mean itll prob take off .1 but that .1 matters to me on the street!
plus it made my under drive pulley install more worth while.
alot less accessory drag, cant wait until i get the electirc water pump!
thanks guys your friend

Is there any power loss with this cam over a similar dual pattern cam?
It's going in an '86 w/ ported 882s, lt-1 intake, harland sharp 1.6's, headers, true duals w/ lt-1 mufflers... car is auto w/ 2000 stall and 3.07's

That's a little bit of a loaded question. Define similar. The Hot Cam can easily make more power than a similar cam, it can easily make less.
Every camshaft spec is going to change the power output of the engine somewhat. If you can post the specs of the "similar" cam we'll be happy to try and guess at how it'll do.

That's slightly smaller than the hot cam from all angles. It'll idle a hair smoother but it'll make less power. As for what is "better" that's entirely your call. With the looser than stock stall converter you can get by with a little bit more aggressive cam and still have good street manners. Unfortunately there is no way to quantify idle quality or driveability and there are too many variables to say exactly how much more power the hot cam will make.
I know it's not what you're looking for, but there is no easy answer.

My setup is weaker from idle to about 1800 than with the standard cam. I can't launch at just off idle like MOJO does because the engine falls on its face. If you race you definitely would want a looser stall TC than stock.
