Well...?
Well...? Got my car running recently and I was too use to my LT1, this is a whole nother ball game.
What do you guys think I'm making rwhp wise? All I know is I'm running enough that my 275/40-17's aren't hooking worth a ****. I was thinking ~325...
Mods in sig...
What tires do you recommend, i was thinking the same size as above MT DR's
I'm thinking about getting Firehawk wheels which would put me around ~330rwhp..

I agree with the 330RWHP. Basically you'll put down the same numbers as an '01-'02 stock plus a ported TB and mac mids and cut out. Oh and the MAF might give you minimal gains. At most I would guess 335 on a DJ.

Question: Why didn't you put a cam in when you had to change the oil pump or the chain? The only power adders I see are the Intake, TB, cutout, ASP underdrive pulley, and the not so powerful mac mid-lengths. If you ask me it is more like 300-310. I have dynoed about 600 f-bodies over the last 2 years and 98's were also down on power from the get go compared to 99-02.
Not trying to be a dick, just being honest.
If you want real power, finish out the rest of the bolt-ons, and go with a new set of heads and a cam to match. Then you are looking at 380-390 or possibly 400+ depending on combo.

I'll break it down:
I had a '98 T/A dyno 311 with borla and free mods (free ram air, TB bypass, EGR mod). You've got a cutout plus macs so I'll give you at least 5 more over the stock manifolds and borla plus the LS6 manifold for at least another 5, ported TB for about 3 (being conservative) and UD pulley for about 5. That's about 18 more than my 311 for a total of 329
You didn't mention having a lid or not. If you do then that's another solid 5 for around 330-335. Some things to consider are that not all dynos are the same. That being said I still stand behind my 330-335 prediction. Good luck and let us know.

Seriously. This guy already has a suspension that will probably land him a good ET. Who really cares about numbers anyway?

I was waiting for that...here is the reason. I live in CA and this state is full of many fartards when it comes to smog. I put this car back together stock and I'm very lucky that my county does not do the two year smog BS.
So what I did was everything that I could do the strengthen the motor and make it pretty, but still pass smog.
Now when I do my heads/cam AFTER my one and only smog i will only have to do lifters and pushrods. May be stupid but that was my reasoning. It's a second car so a little garage time is just fine. Since I did everything myself I know I can do it again.
The wheel thing was a joke obviously...
btw I plan on doing the stage 1 or 2 LS6 heads and MS4

Then again I'm use to a nearly stock LT1.
oh and I forgot to mention this is a '00 LS1 motor, w/ the 28.8 injectors I already had. I didn't even notice the 8.8 and yes that combined with the auto will rob some power vs. an M6 w/ a 10 bolt. The reason one guy said 98's were down on power is b/c of the heads they came with. New prediction: 325

Thank for the info!
