Well..to be totally honest with you...We really do not know exactly...
It is a 440 with a 30 over bore and TRW pistons, it has a higher than stock cam, a 284 or 288 if I am not mistaken. It has a 850 Holley 4 barrel and will now sport a "new" set of Indy SR Alum Heads.
It was purchased like that, I am only adding the heads. The car seems to be making awesome power, especially compared to my previous Chally....
All other changes have been purely cosmetic, new stereo, color and wheels....
The rear pumpkin has seen drastic changes, as one of the bearings gave way, leaving the axle to do what it pleases...I had to take it to the machine shop and let them put new housing ends and straighten one of the sides as it was a little bent....It got new bearings too....
This little mishap also let to the limited slip and pinion bearing being destroyed and I opted for a spool and 4.10 gears...
There are a lot of other changes the previous owner made to the car....
Later....
