Need expert opinions on a statement that is part of an ad for a ‘72 LT-1. Would this bother anyone...
The long time previous owner pulled the engine and had it professionally rebuilt. Using only the veryvery best of parts, the engine now produces 370 Horsepower instead of the original 255 horsepower. Asteel crankshaft, higher compression pistons, better connecting rods, larger valves and a higher liftquality camshaft turn this Corvette into a responsive and impressive performance Corvette.Thanks, Keith

Receipts? Crank, rods, valves, cam may well be standard LT-1, better than run-of-the-mill small block.. perhaps the new pistons bump the compression back up to 70 numbers from the 72 9 to 1.
I'd ask for more details re his comments. Compare engine S/N to car VIN.
Do you have photos? Tach? I'm uncertain of 72 red line. Half shafts should have caps not U clamps on the U joints.

Don't believe the LT-1 heads can handle lager valves. I seem to recall there wasn't even room to put steel valve seats in the 70.
Micha the radiator in the Steel Cities car appears to be original, the Top rail has the correct punchings... there is a date about 4 rows down on the passenger side towards the engine compartment. will be A1 B1 C1 Jan 71 Feb 71 Mar 71 Etc
You can fit 2.05 valves on the intake side (I have had them done)... but that's it.

As long as they didn't alter the deck stamp or destroy anything original it's just a better engine.
FWIW if you run the 9.0 pistons with out running steel shim gaskets your CR is down around 8.25-8.5 to 1.
I prefer going with solid rollers in the engines I build just because they make great power everywhere and they have great vacuum at idle.
@firstgenaddict : Thank you for the adivce. I'm quite sure the radiator is not the orginal one as it has been renewed to be able to work with an added A/C (as we know only available on 72 models).
The previous owner has done some improvements on the car, but he is delivering all the original parts with it.
Thought personnaly, I wouldn't have done these work on a NCRS top flight judged, but I'be no ambition to make it judge again...and these works were to make the car more comfortable. So... I'm fine with that.
The good news is that I'm officially an LT-1 owner. Title and BoS have been signed and the car is loaded on a truck to be carried from Arizona to Miami sea port. Then has to be shipped out to France to Le Havre Sea port... 3 to 4 weeks of patience before getting it my garage.
Thank you all for your help and comments.

The trip is beginning !!
Congratulations. I can only imagine how much fun you’re going to have with an LT-1 touring through a French countryside. Nice color choice, my personal favorite. I have a ‘72 convertible in Steel Cities Grey, unfortunately not an LT-1. Regardless, I get nothing but compliments on that color. I’m sure you will as well. Enjoy.
Congrats on your purchase... Steel Cities Gray looks so good on the car.
I would love to blast through the French Country side in an LT1.... color me envious!
Thank you all for your encouragements and congrats. I'm so impatient !! The car is now in Miami seaport, waiting for the boat. ETA in Le Havre France around the 03/31st.
Jumping to another matter : does anyone knows what are the stock options coming with the LT-1 from 1970 to 1972. I know that the A/C was only available in 1972 with a lower rpm.
But what about all other options that were offered on other C3s models. Were they also available on LT-1
Would be interesting to know.
From Jan - April 1970 the LT1 ran the CTU coded engines which have a larger oil pan and the pan interferes with the power steering ram so Power Steering was not available. After April 70-71 LT1's could be ordered with all options EXCEPT A/C.
My car has Power Steering, Power Brakes, and Power Windows.
@67 L79 Vert : Thank you, that's very clear for 72. Can you picture - just for LT-1 - the factory options available in 70 and 71 ? It will probably confirm @firstgenaddict @dan1495 : Here's what I've got in the Richard Prince book about ignitions :
@firstgenaddict : So to summ it would mean that all factory options were available for LT-1 excepted : -Pow.Steer. for 70 CTU engine code and - A/C for all 70-71 mods. ? Am I correct ?
