Hi Paul !
First! , thanks for taking the effort to answer...!
Well im a bit stuned...., not for the figures of HP , because in that area there is many discussion about those things , no matter what car . But! al my paper work just keep on saying 365 HP (sae?/gross i dont know for sure) books, Other Olds fans and folks, olds engines websites, etc etc for the 70/71 L31 engine... , The compression ratio is above 1:10.3 , as i cheked that and has dual exhuasts ( i believe without it was 350 ..). ( motor is still 100% original and untouched!.) but as said . lets leave that for know, its not THAT important , its fast , that i do know ( and i am a dragracer so i know what fast is.........

For sure ! its not an oldspeople car...it handles very good aswell! ( very thick stabilizers,anti roll bars etc(i believe original.)
I ask info here! so thats why i ask on this forum... so DONT think my comments are against you or something, NO THE are not !, just doubts and free discussion too learn more about this "strange" ? car ....
I cant remember where or when... BUT someone ( internet) told me once this car is one of about aprox 36 build sporty Olds ( in this set up) , and little is known about it , i didnt give it much thought back than , but i always asked myself , well , what about that , how can i check etc... and over here almost nobody knows anything about types of cars that are different than the standard cars...
BUT: , i will make fotos of all the emblems (the olds L31 ones ), but the realy seem VERY original!!. ( one on each front/side fender and 1 on the trunk, )
Also it says L31 on the hood in the small stripe around the black out part of it ( on the sides in red letters. ( i have a pick from that, and will also uploud later..) & why should someone fake that and SCREAM L31 everywere with emblems etc, if the motor is only 225 hp etc ?
BUT ? maybe someone did...? and had al decalls and stripes etc specialy made etc, you never know. Although i cant believe that...
The rear decal / stripe says 455 rocket on the sides ( the rocket word in gold/yellow ish..).and seems very original and like it has been always on the car.
IM NOT sure the blackout hood is the original way , but the stripe around it, the decalls and all other details seem original.
I have full buildsheet etc with the car ( and al original cowl and trunklid stickers are still in place.) so maybe we can find something there later on ?but i cant decipher all those codes, because a lack on input...

.
Offcourse i will check you emble,/spec list too ( dont have the car here)., and tell you what i find there too... So ill get back too you asap..But the al seem to match , exept for the additional oldsmobile L31 decalls etc.
Another forum member here is checking out the car aswell i believe.
THANKS for know... !!., ill give more info asap ( ps dont misunderstand my bad english... , im dutch so difficult to realy communicate in a good way in mails...)
