Sounds good! That ought to put some life back into that cuda. So are you still selling your motor?

Make sure you read the comment he left for these.
Good Score.
Your gonna pass me going down the 1320.
It should go real nice with the 904 and converter you have.
Good luck.
 
I saw the comments and we discussed it. He said to make sure to keep it out of detonation. It wont see enough street miles to worry about other then that and later it will get a 4" crank.

I may still sell it so I can buy a nice set of headers for the new motor but my father asked about it for the 89 Daytona he just brought home so it may go to him. After all he was nice enough to loan me some money for this motor.

This moto ran 11.60s in Dwaynes 3500lb 68 Satallite. Sinve he pulled it he freshend the motor did more port work to the heads (260cfm @.500") cleaned up the intake and added another half point of compression. He's going put it back on the dyno and set up my carb for it. He says it will probably make around 470 horse.

Im going to need more gear. He was shifting this thing at 7500rpms :-D
