well, Kody and I were able to get out to the track for one more night of racing tonight before we called it a season. i was totally stoaked at the times we got as i totally didn't think we were going to do as well as we did. remember, these cars are 100% daily driven and 100% naturally aspirated. race weight for Kody's car with him in it: 3255, race weight of my car with me in it: 3220
i'll start with Kody's car cause i haven't really told many folks about it. combo is super simple:
-305 out of ssean92's 1992 RS
-416 casting heads with backcut valves
-lt1 cam
-crane energizer aluminum roller rockers
-hedman longtubes with manderal bent y-pipe into a 2.5" dynomax catback with homemade cutout
-holley street dominator intake (the smaller of the two, basically a performer) and an edelbrock 1406
-2100 stall converter w/ 700r4 and 3.23's with a 275/50/15 mt ET Street Radial.
previous best was in the upper 15.2x range, tonight with the cool air it went 14.67@93.7mph. we went from a 28" tire to a 26" tire and rebuilt the carb and added more timing. the car needs some more gear bad. timeslip for that pass looked like this:
r/t: -.123
60': 2.205
330': 6.166
1/8: 9.441
mph: 75.20
1000': 12.276
1/4: 14.678
mph: 93.73
we were hoping for some 14.9's, so to get a high 14.6 out of the car was like walking on sunshine.
now for my car. alot of you know that the solid camshaft that was in the car was hurt and i put in a used 280H cam that my friend Eric gave me. i totally didnt' expect to even break into the 12's and i did that at the shootout we had back in the end of september with a 12.97 @ 103mph. air was SUPER nasty that weekend and i was trying to run a 13.0 index class so i wasn't looking to go blazingly fast anyhow. the previous best for my car with the solid cam in the 305 back in may was a 12.50@106.8mph. that was with hotter weather, a water pump drive kit and manual steering. this evening the car had full accessories (water pump, alt., and i put the powersteering back on) so i was going to be happy with 12.7's. i figured that would be possible because of the cool air. after screwing around on a few runs trying to get reaquanted, i clicked off a 12.42@107.49mph! the timeslip for that pass looked like this:
after that pass we decided to see how fast we could actually get the car to go. i knew that the powersteering was worth atleast .1 so i snatched the ps pump belt off the car and proceeded to go 12.39, followed by a 12.34, and then finally a 12.31@108.48mph!!! that pass looked like this:
as you can tell, i'm so pumped about it that im writing a thread about it at 1:18am to tell ya'll. anyhow let me know what ya think. oh, and check out a pick of Kody's ride all ready for the track wearing the mickey t's!

I love the 280H cam it makes VERY useable power everywaere. I put a used one in my motor and it woke it up compaired to the xe274H that was in it. Nice pass
Seems kind of odd that it made more power seeing as the 274 is an extreme energy series with faster ramps and more lift whereas a 280H is an older grind with 230/230* @ .050" and .480 lift on both.
You continue to baffle me. An "older grind" cam, (a mere 230/230), A 305, going 12.3! 108 though, that sounds low to me..? Is it? You're getting fantastic traction, but not a lot of speed at the end?
You're using... the 113 AL heads? and down to 3.73 gears? Think the gears changed much for you?
Does anybody at the track still believe you, when you tell them it's a 305 in there? I imagine not
I hope you noticed the 2 threads in the fabrication forum showing how 2 members retro'd 2nd gen rears into their cars. More ideas eh?
I dont like the xe series cams that much i had 2 of them and neither impressed me and they seemed worn hard. The magnum was used and looked brand new and i had the 270H, 280H, 294S, and a 302H all magnum line cams and i LOVE them and they have awesome idles.
OK I calculated the DA and it was -1290'. That will explain a lot of the pickup for you. You should really keep track of that along with performance data so that you can properly analyze changes to your car.
For example my 11.72@115.14 at 3000' would be 11.14 @ 121.23. Your 12.32@108.48 would be 12.96@102.93 @ 3000' DA. While we are only 0.6 ET and 7mph different on the internet, we'd be 1.2 ET and 13 MPT different at your track. Density altitude affects numbers big time. Especially at tracks close to sea level and in season's that approach freezing temperatures. I'll let five7 and Stephen figure out and dream about what they'd run in your conditions.
Just my $.02.

well, thanks for figuring the DA out for me, and yes, i know i need to keep better track of it. the air is always better at this track though cause it's only like 300' above sea level. though i wasn't trying to compare my budget built 305 car to your not so budget oriented 406. the fact is, that i still have a 12 second 305 even in your conditions...that's pretty good if you ask me.
sonix, yeah, it's kinda funny, i have to show people casting numbers now so that they don't call BS...no one believes me anymore, but i know it's truelly a 3.766" bore 305
I was just showing how it makes a huge difference when posting times on the net. When comparing to local guys at the same track its not as big of a deal but different altitudes and different weather can stack the results largely in someones favour when comparing.
Showing a pass corrected to sea level for DA lets others know what the motor is really doing. Its impressive regardless but a guy like Sonix in Calgary would only be running mid 13s with the exact same combo at his local track which would seem much less impressive if he reported the results back here.
Trevor Jacek how can I figure out DA? I figure it musta been good sat at etown: 40-42*, 31.04-30.74 baro

What would the solid cam have pulled with that air quality?

Awesome times!!! So are you thinking about sticking out the 305 a little longer, or are you still thinking BB!!! Nice to know where you are at though, as the car is going under the knife in a few weeks.
I have to say I really look forward to your post about your ride! I love to hear about old school combination making power and running better than cars with new tech and bigger engines. Your making me consider selling my $2000 EFI epuip. and putting on a carb! What size carb and intake did you say you were running and PLEASE tell me how you launch your car?
Dang that 305 is FAST! Mustang owners can't talk about how slow 305 sbc are anymore!
Those are crazy fast times for the 305. people don't believe my 305 either (it's no where near that fast) but i love the look on people's faces when you can tell them its just a 305. I'm hoping to push one into the mid 8s (1/8th mile). Keep goin with the 305 beast!

Good job,
You guys know how make those 305 fly! I would love to build a high rpm 305
great times Mw. I was there with my buick buddies and saw you run. it was very impressive. I wanted to come talk to you but i just didn't get a chance. You're making me want to put another 305 together.
now just think how much quicker your times would be if those were 350s in there

Your right he will be quicker but its the fact that he did it with a low budget 305! I have never seen a article in any magazine over the years where they built a low budget 305 and ran low 12's! But I have seen a lot of articles with budget built 350's running low 13's. For years everyone been saying its just not worth it to build a 305 well he just proved everyone wrong.
his car and that chassis with a 350 would be faster. now because his DA was - as well helped his times as pointed out earlier in the thread how much slower it would be at other DA's. 305s are great to play around with but I go by the hp/$ way of thinking. I try to maximize HP with as little $$ as possible and that's with 350s over 305s.

You don't have to show me. My 3.776 bore pulled 423 FWHP, much to the dis-belief of the dyno operators. I had to pull a head to show one of my buddies after the pulls, he was still in dis-belief. He then asked me where that engine came from, I said it was the "OLD" van engine, he looked dumb founded when I mentioned that. He had thought that my 15.1 @ 96 MPH runs were with a 350.
EDIT- I guess I should mention that the cam was only a roller with like 233/237 @ .050 duration and was being fed by an Edelbrock TBI performer 3704 intake bored to 2" with a 454 TBI unit on top.
found a video that a buddy of mine took of my very first run of the night. a little tire spin from a poor burnout, and i actually ran a 12.65 on that pass, not a 12.68 like the guy on the video said. figured i'd share:

haha! it's started making a small amount of noise on acceleration/cruise, but it's still doing just fine! actually, i'm going to a 4.10 gear as soon as my buddy gets them to sell them to me! the gentleman that was running the christmas tree said that i was day-lighting the front left tire and i want to be able to really pick them up. so once i get my daily driver done, this thing is getting trick springs and 90/10's.
Let me know what the axles look like when you pull it apart!!
Those are some of my operations for this winter (money prevailing of course), but it at least is getting a 4.56 gear. It may seem like a little much, but I am running a 28" tire. I hope to at least get the struts this winter, but there are some engine mods in the works first. They are having a t&t at my track this weekend, but I think that I'm going to skip it, so I can use that money to start my winter upgrades!
man, that's a HUGE gear jump. honestly, i'd do the gear swap after the first race next season, after you've seen what the new combo does for you and see what the engine wants, instead of just throwing gear at it, cause that's a BUNCH of gear.
congrats on the 12.3 man.. does the power steering really do that much?? i'm at a 12.41 right now and i'm pushin for lower.. also i noticed the 1.6x 60ft.. thats really good compared to my 1.81 best.. but i trap at 110mph compared to your 108.. you got torque, i got hp.. haha.. how does your rear suspension look? i got stock springs, LCA's, TA, panhard, 3.89's, descent napa shocks, and 275/50-15 MT ET radials.. it doesnt hook, and i'm stumped.. i spin every run or i just bogg down.. tough game.. but once again, congrats..
the et street radials really don't work well with a stick. the shock that the sidewalls see from a clutch dump are too much for that tire. you really need a bias ply slick.
as far as my suspension setup:
stock lca's with poly bushings
lca relocation brackets to fix the lack of instant center.
stock torque arm with poly bushing
spohn panhard rod, only becuase my stock one was bent (previous owner did it somohow)
v6 springs all the way around
monroe replacement rear shocks and factory struts.
in my car, the !powersteering belt mod is worth .1 and 1mph. has been ever since i built the 305 back in 2003.
Matt, these reason for the huge gear jump, is that I was only turning 4200 through the traps. Don't worry I'll keep the spare 3.73 around along with a swap meet 4.10 that I picked up this summer.
congrats!

people don't believe my 305 either (it's no where near that fast
) but i love the look on people's faces when you can tell them its just a 305. I'm hoping to push one into the mid 8s (1/8th mile). Keep goin with the 305 beast!
