Default predicting numbers...

I know it's not really a good thing to do, but I'm curious as hell.

I'm almost done putting together the motor for my Firebird. I'm swapping a LT1 into my 95 3.4 car. It's been a long road and I'm ready to be driving it again.

The end setup will be:

-355ci LT1 (bought the block used with aftermarket crank, SCAT rods and SpeedPro pistons)
-Stock 93' Firehawk heads milled to 11.1:1 CR & 3 angle valve job, all new valves and Impala headgasket
-Comp 918 springs
-Scorpion 1.6RR
-CC503 cam
-double roller timing chain
-CSR electric waterpump
-hand ported LT1 intake
-58mm Holley throttle body
-stock injectors
-JetHot LTs and ORY

What should I expect or what numbers could I be seeing hp/tq wise? I have a number I'd like to see but I'm curious what other people think.

I edited the info, I listed some stuff wrong. The heads are from a 93 Firehawk, not the intake. The heads supposedly flow better then the 94+ heads do. Also I had all new valves installed...

I was lookin a guess for more on power numbers hp/tq...

As far as driving...I could drive the **** out of my V6, turns are one thing though, I've been more into twisties and what not more than straight line. Obviously because in the past I've just gotten embarrassed...

...so I guess we'll see...haha

Is this an A4 or an M6? Either,you need 3.73 gears. If an A4, you need a high stall converter.
If you can get it to hook, low to mid 12's should be obtainable. Good luck.

Looking for hp/tq numbers...the car really won't see the track much. I really don't feel like going through 10 bolts and don't have the money for a 12 bolt or 9".

Depends on how much work was done to the heads, whether the car is A4 or M6, but I would guess in the 330-350rwhp range.

I dynoed 330rwhp thru my automatic with stock untouched heads and just full exhaust at the time. With a stick I'd imagine close to the 350 mark. I know your not super interested in track times but you will have the potential to run low 12's IF you can hook. I trapped just over 110mph shifting only at 6000ish and remember I'm auto so stick maybe 112.
