well i finally got my T/A in my sig tuned. i used a COMP 228/230 .571/.573 112 cam with off the shelf AFR205s and an unported FAST 90 with 90mm TB. oh yeah and Pacesetter LT's, TSP ORY, and Corsa Cat back. anyways, i wasn't sure what to expect but from what i've seen from other people's builds using stock 243's or AFR205s i was kinda thinking i'd make more than just 446/426. i'm not really complaining, since my buddy's 383 LT1 made 442/421, but i'm wondering if the MUSTANG dyno may have cheated me a bit. any thoughts?
oh yeah and i think there may be a few more horses in there, too. the tuner made 3 pulls and made a couple tweaks after the third pull, then unhooked her from the dyno and said she was done. the last dyno tune i had done, the guy made 8 pulls just to make for damn sure he was spot-on and had the power maxed out.

well i had him put a ball park tune on the car so i could drive it to him, so maybe he already had it close. first pull yielded 423/402. then 435/421. i may add a couple more bits and pieces to try and maximize output, but i'm staying away from the EWP. in any case you are right, i can't complain. drives smoothly and behaves very well, AND makes more power AND torque than a fully done-up 383 LT1 ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
oh yeah, and peak power came at about 6,400, but it didn't nose over, it pretty much just leveled out and kept going til 6,700. if i was more confident in my valvetrain i could turn it up to 7k
i'll put up a dyno graph ASAP.

yes, i got a lower lift cam with XE lobes for valvetrain longevity. i'm running 3.42's in the rear right now but am considering GM 3.73's (i don't like 4.10's, too low for me.) also it was put on the dyno with 800 miles on the motor, so even though it feels good right now, i think it might have some more breaking in to do.
anyways, the only reason i thought they might be low is i remember one member here put down 444 with a 224R cam and unported 243's. and also i recall a similar, but a bit more extensive build than mine yielding one member here 500.2 so i thought i would land right in the middle of the two. and pretty much the only bolt on i dont have is EWP and coils. also i'm running pacesetter longtubes with a TSP ORY, so i'm thinking if i had the good stuff it'd be worth a couple ponies.

yeah that is why i got a tr224. valvetrain longevity is important to me with a daily driver. you made very good power. goes to show lift may look impressive but its in the combo you come up with also. congratulations.

just finished my build as well... comp 231/239 617/621 113, FAST92/92, TSP 1-7/8 long tubes, prc stage 2.5 5.3l heads, stock bottom end rendered 444rwhp/405rwtq.. granted this is set up to run on a 150shot as well but i'd say your in the ball park you should be in..

i dynoed at a shop in vancouver, WA. should be back in NC soon so i'll try out a dynojet down there
i'm running the SVO "green top" 42# injectors. and honestly i'm not sure what the 230/234 cam would make, but from what i understand the AFR205 was designed to run with a high 220s to low 230s duration cam. and if you have more lift than my .571/.573 i'm sure you'll pick up a few, but that was a personal decision. i wanted my build to be fast, but still have good qualities like reliablity and halfway decent fuel mileage. if it wasn't for today's failing gas quality, i would have milled the heads to 59cc since i had plenty of PtoV clearance.
@greyghost4x4, those numbers look good to me. i've been wondering if stepping up the header size would help as well as going to a FAST 92. and my rings are gapped for nitrous as well, i may run a 200 shot in the future after i replace my 10 bolt.
