Right now I'm at 371 and that's through an automatic tranny with a high stall converter.

My track times are in the signature, hopefully I will be decreasing that time some more. Just installed some 3.73's in it.

I have homported heads, shorty headers, X230/236 114LSA, and other bolt-ons and I pulled 351rwhp. I have now added (or started to work on) Stage 2 ported heads, longtubes, MAF, and 52mm TB which I hope gets me to 390rwhp +.

As far as 300rwhp on stock heads, I did that with stock cam too Just bolt-ons.

I dynoed mine today... I have the XE 230/236 with stock heads. My car put down 317 rwhp and 325 rwtq. Not too impressive, but it was 94 degrees this MORNING when I dynoed. I never did any dyno runs when it was stock, but car feels better, my mods are in my sig if any of you want to flame my numbers...

Nice numbers man. Was your car dynotuned, or do you just have a mail order tune? Keep it up man.

PCMforLess Tuning.

FWIW, I used to have an XE 218/230, 112ls cam with some ported LT1 heads that pushed 358rwhp & 355rwtq w/o proper tuning.

This was with a 3" cut-out open. Corked, it ran 15 less hp & tq. Yes, cut-outs work great!

I also had shorty Edelbrock headers w/ the smaller primary tubes.

In other words, you should expect higher than my numbers with that cam. GOOD LUCK!

Times and dyno numbers in sig. Mail ordered tune through shorty headers and full exaust.

NiteRider

sirhc reuab

how does that xe cam compare to the cc306?? bigger ? smaller? sorry i dont know cams very well but im in the process of deciding on a cam for my stock heads car.

93formula

i thought it would be around 300 rwhp with stock heads, once you port the heads it should really open up the HP potential!

Formula_one

I already gained quite a bit, but most of it was my own stupidity... I left the stock valve springs in the car after the cam install... Not smart, believe it or not they werent coil binding either!!!(the valves just werent opening all the way..) I dynoed almost 3 weeks ago too and put down 260 rwhp with the stock valve springs and 7 cylinders!! My #7 cylinder was arching off the block, it was purdy... I gained almost 60 rwhp from the springs and a spark plug wire... lol

Also, those numbers I put down today was in 94 degree weather too...(that is a tucson morning... )

NJLT1SS

I just got done installing stage 3 TEA heads and the XE230 cam. I only have about 20 miles on the setup so far, and I will be getting a dyno tune done with Bryan at PCMFORLESS. I have a mail order tune right now, and the car idles well, and driveability is very good, not that far off from stock. When I get on it, the car feels faster, but Im not really sure by how much. I need to get it on a dyno and see what numbers it lays down.

I am just like NJLT1SS... I just got my car running last night and have put about 20 miles on it so far.

I haven't really gotten on it yet, but so far it doesn't feel that far from stock. Again, I haven't even taken it over 4,000 rpm yet.

It is also on stock tuning. I am soon changing to ODB1 and a custom program using Tunercat.

Do you have headers? I felt a huge gain!
