Well,
I am in silverdale, wa. I am a Marine stationed a Bangor. What havent I done? Uhhh...335 Stroker, Larger TBI and injectors from Turbo city, Comp cam, 10.0 to 1 comp ratio., World products S/R torquer heads, list goes on and on...I dont think I left anything stock as I went on a crazy binge to prove everyone wrong who said i couldn't do it with a 305 TBI. Check out my page at Cardomain. The only thing I havent done is get the comp reprogrammed and dyno tuned, but I have a guy who is going to do all this for me so I can call it a "balanced and blueprinted engine"...and I'll have numbers
I crushed an 02 Supercharged Harley F150 and I beat a 98 LS1 Camaro. http://www.cardomain.com/memberpage/677112

Another Marine here making over 300HP. Probably close to 330 and over 400 lb/ft. Not dynoed yet as the car really isn't broken in very much, and she's been at the paint shop for over a week now.
I still have some 1.6RR's to go on as well, so maybe another 10-15HP on top of what I have now.
These #'s of course are based on people who have a similiar motor to mine. Hard numbers will come when she's broken in now. My biggest problem is crap tires not getting any traction.
I'll most likely solve the problem with either BFG KDWS or Pirelli P Zero Nero's.

I'm guessing I'm making right at 300 at the crank, I've run a 13.9 @ 98 mph, thats with a 3800 lb car, (just think of it as a really heavy thirdgen).
350
comp 268 4x4 cam
stock crapy heads
full exhaust
rpm intake
454 tbi 70 lb injectors turned up to 22 psi
lots of tuning
gets 22 mpg

I've got a 350 HO goodwrench engine rated at 296hp, and then have p/p intake, ultimate t/b mods, serpentine belt conversion, 350 injectors, rapid fire plugs, custom prom burning, msd wires and control box, msd coil. Im thinking about 315-320 hp? I know I am over 300hp though.
Had a monster 305 before this that was pushing 285HP, ran a 13.7 1/4 with timeslips to prove it. It had almost every bolt on, then it got supercharged, ran a 14.6 on a fryed clutch ( wonder why?!!) and never got it back on the track. All that is gone now, im starting over!

Last time I checked on dyno 2 years, it was 275rwhp and 347rwtq. Using stock short block 350, Corvette Xfire. CompCams Roller Cam/ TFS heads/TPIS headers. With 3.07 rear, 4+3 trans and street tires it ran a best of 13.65 at 101.

Gunny,
This was an off-the-shelf CompCams Extreme Marine cam. The specs are 264/270 @.006, .488/.495 using 1.5 rockers and 112LCA. Very nice cam for the street especially since the torque is RIGHT THERE. It peaks off somewhere around 4700rpm. I've since installed a single pattern cam to take greater advantage of the I/E flow ratio on the heads.

Are running an auto or manual?
I'm just curious because I also have the 23* TF heads as well.

Your probably right gunney, I haven't gotten it back to the track since I got the TBI system all worked out and the injectors out of the static range. It deffinetly feels much stronger in the midrange. I'm also only running 3.25 gears so I'm sure thats hurting me. I know Lt1's aren't a problem so it's making more than that.

I was actually using 1.6 rockers for a 520/528 lift. The duration is 212/218 @ .050. My new cam is a 528/528 with 1.6's and 218/218 @ .050. I believe part of the problem with making power was that I was running lean at WOT. I found out with my new cam that I needed to pump up FP. I'm also using a Xfire manifold (albeit modded) which may explain part of the power dropoff. The trans was a 4+3, but I upgraded to a ZF-6 this past winter. One reason I decided to go with a new cam was to increase overlap. I found that my static compression was over 200psi with the previous cam probably generating some pumping losses in the higher rpm ranges.

Hi Dom! 224/230 @ .05 is in car CC 268 XE 114 LSA. holley projection intake installed with 454 TB sitting on top. only have 1/8 inch clearance to hood with drop AC. trying to sort out the wiring this week to TPS/IAC. should have car running later this week. if i can get the PE in line with WB02 will run on dyno if weather behaves.

Ok, you all seem to know alot about how much HP you get from what so here is a question for you all. I got a 350 (stock cam) with TPI 350 heads, intake (going on this weekend I hope) Intake should have 2" bores, open air element, cat back exhaust, 55lbs injectors and thats it. Any guesses to what I should have?
i had 12 lbs per gauge on cold engine idling. i will move to 14 when i get car running. 80 lb injectors(i was mistaken when i thought i had 90). 12.5/1- 12.90/1 on WB in PE. i will command 12.0/1 and start all over with tuning. whole different ballgame.
no i am not going to use the vacuum assist. dont see a reason to at this point. if i had a larger CID that would be a possibility. with old cam i had plenty fueling. i may sneak up on PE till i feel comfortable that the injectors can fuel it. do you think i will need the most fuel at peak TQ(rpm) at max load(3rd gear of 5) ?? actually with old setup i just ran some Q mile blasts. never tested top end for fear of police. car is real loud when on the gas.

Just hooked up my ZT-2 WB this weekend. On recent scans, I can see that the PW is going static on my 80# injectors. What I don't know is whether that equates to 14:1 or 10:1 AFR.

You know, a stock cam. One they throw in a 350 from autozone. Not like they put in really good cams from there. I dont know if a camaro cam is in there or not. I have no idea of what is in it. All I know is it is a 350 that fit my 89 camaro perfectly as far as bolt patterns and such and that it is a 4 bolt main.
Edit: Am I using the right size injectors or should I go bigger?
