Thread: From regular to 11's

  1. #1

    Default From regular to 11's

    The majority of us went through "steps" to get our trucks moving a bit better than what Chrysler provided. Ppl did anything from starting with CAI to ignition boxes to full race engines. Some did nothing but add boost or nitrous to a completely stock engine.
    So my questions are these:

    1. after you did the cam (how large?), heads ( full port or warmed over?) and intake thing, (port matched or hogged out?) what else did you do boost wise, (lbs?) to break into the 11's?

    2. Anybody here in this category with a stock bottom end and by that I mean "untouched rotating assembly" or did you have to go pistons or stroke? Please mention whether you own a cc or rc,

    3.After all this, can you still consider your truck able to go anywhere any time you want to or did you take the street mostly out of it?

    Now I mentioned nothing about tires, chassis and tranny or rear gear set, but I'm willing to bet that even with nothing exotic done here like a 4 link, with a little combo work in this category, you've found .5 right there.

    Do some searching using "Danno or Barney" for search words. I looked briefly but, didn't find any threads with his engine combo. This was way back in 2000-2006 before all the modern "go fast goodies". Barney was his 98 DA CC that he got into the 11's on the stock bottom end. I don't recall any specs on said items. He did 4 bbl intake & TB, massively ported heads, nasty cam, several different header combo's over the years (pph, Spintech mids to custom built JD long tubes). Trans was stock other than a P.I. 35-3800 rpm convertor Third member was the stock 9.25 with 4.56's to begin, ending up being a Detroit locker, 4.56's. And, a 150 shot off the line to propel him to 11.59's @ 118 IIRC. Yes, it was street drivable, he didn't/doesn't mind the quirks of driving a fully modded rig. He drove it to California for street truck shoot-out of some sort early on. And, of course most all of the DRTC national meets. We are still good friend's and try to get together a couple times a year.
    p.s. Search the members name and threads/posts.

    My first n/a 408 “pump gas” ran 11.2-11.3 with stock trans with a valve body and converter change. I still drove the shit out of it on the street. R/T heads flowing in the neighborhood of 300cfm, large cam, 4.56 gears in a Reg cab.

    Second n/a 408 ran about the same. Never got the bugs worked out I don’t think. 4r70w transmission. Had a roller on a lifter fail and wiped out #4 intake lobe. Still went 11.7 on that pass. That motor is sitting on a tire in shop. I’ll fix it and throw it in something one day.

    R block 429 n/a is what I’m currently running. Went 10.8 @ 128 on e85 fuel. Needed more stall in the converter, I was dropping 2100 rpm in between shifts. Just put new converter in. Ready to go run when tracks open.

    Chris, You had/have some fine running na's there. Streetability has to be in the mix for me. Dn't care about gas mileage but need a truck when I need a truck. Basically what you did was to stroke to get the power you want and drivability. The 408's you had sound very interesting and you deserve creds for getting to such numbers NA. I just want an 11.8 truck without going all psycho on the engine and by that I mean taking the daily drivability out of it. Thought boost was the only way to get that. Question: you build these and if so, what were the similarities between your 1st and 2nd engine?

    Dart99, thanks for the heads up on those names. I always thought that the 360 needed a boost (or stroke) of some sort to go fast. I'll look these guys up. Thanks.

    Ain't that what they use in Fords? Adapter of some sort to hook up to Mopar?

    2nd 408 had a little more compression bit more head work. Never really got it all out of that build, lost the lifter and kinda just moved on. Had a bell housing made to adapt a 4r70w to sb mopar.

    Your best bet is boost.
    Streetable when driven sensibly. Power when you call for it.

    Ok To summarize. To break into 11's, one should have: 1. 4 barrel TB, 2. cam in the .230 range w lift over .500 3. 4.56's, 4. converter of at least 3000 rpm along with some tranny work, 5. heads flowing at least 270 cfm, 6. Tires and some suspension work, 7. more easily done with boost or nitrous. 8. tune.

    Without forged stuff, or at least rings gapped, not to be done too frequently. About right?

    Name doesn't come up in "search". I'm thinking he ran over 12lbs or had mega work done to his heads. It's like I got here 10 years too late. Man I wish someone thought to archive or sticky this stuff.

    12.10@106 (bent a pushrod at the 1000’ and let out, should have been my only 11.xx pass)
    This is with a stock short block, stock heads and stock cam. Only upgrade to long block was 1.7rr’s, 2bbl M1, and 58mm TB
    Calvert mono-leafs and traction bars, QA1 shocks, Bogart drag wheels, Vortech V2 with 8-10lb of boost, 42lb injectors, STOCK fuel pump, Longtube headers dual 2.5” w/cats, SCT Tune, martin saine trans with 3600 stall converter, 4.56’s and 4000lb Club Cab.

    It’s been under the knife for a bit, wanted to upgrade stock heads valve train to take some more RPM’s after bending a pushrod, but threw on some edelbrocks and it’s been a snowball of parts since.

    Thats pretty good GF.
    I don't do "social shit" of any kind so I can't see your progress on Instagram but what surprises me is how fast you went without the heads, cam thingy with just boost. I mean stock cam is like what, 196-206 @50 with a whopping .417 lift? The 1.7's boost this some but it makes me wonder why I put in a .216-.226 cam with .520 lift.. The stupid Air Gasp flows crappily. Theoretically, with a centrifugal, I should break into the 11's with the net 4.22's with 26" slicks. Only 2800 stall but it certainly doesn't feel like I'd make up that much with what I have (guessing low 14's). Tranny and 56's should be good for .5 so lets say 13.7'-8's
    Certainly your 56's and stall helped and the MS tranny.
    Makes me wonder why we tear into these engines at all instead of intake, TB and injectors and centrifugal with a bit of chassis work.
    One question: how'd you arrive that you needed 42Lb injectors instead of a 36 or so or even 24lb ones?

    On a data log you can see the injector duty cycle. So if you hit 100% on WOT you need bigger injectors.
