    Something a little different at Keystone last weekend.

    That is awesome. I often wondered why old nascars don't show up more at tracks. I see rollers for 3k sometimes. What was his best time? It should have more in it than I saw on the video, no?

    I'm thinking I put too small a cam in my 360 Magnum...

    I wish you luck my friend. I can't say I would purposefully build a nitrous combo with stock cast pistons. And if they weren't specifically gapped for nitrous, you could easily butt the rings and pop the top right off of them with 200. Be really careful with your timing, and read plugs every hit

    I'm thinking I put too small a cam in my 360 Magnum...

    There's alot going on here.... stock cast pistons, what ring gap? Assuming no anti balloon plate on the converter? Going to put 1000 cfm worth of carbs on a stock 360 cid engine? And ya, asking alot of a 7 inch slick if you're going to just hit it off the line.

    **600hp sbm block limit? Or is it bs!!**

    Yup pretty close. My home track is actually a tad uphill believe it or not. With a 3.91 gear it does 10.20's. On a 10 in slick, with a 26 inch tall tire. Mph usually 129 ish.

    **600hp sbm block limit? Or is it bs!!**

    There's some videos of it making passes on there. You are right I probably don't have a build breakdown. I haven't done much on YT for ages! It does hang with the big tire cars tho!

    To get back on track :) My personal LA 408 made 608 on an engine dyno. Was raced every summer for the last decade, shifting at 7400, and I put it on E85 2 summers ago so I could get off race gas, and actually enjoy it on the street a little bit. Big solid roller cam. About 13 :1. Timing...

    Black Friday sales. Who’s buying what.

    The only place is really stuck was where the previous owner burned through the clear coat on a botched polish. This is as good as I'm gonna get it before I let the body shop DA it.

    Black Friday sales. Who’s buying what.

    They had a little 15w acoustic amp on sale for half price I nabbed. Ended up being pretty nice! I did see drum sticks on sale too. My annoyance with that place is the dualing shredders that just want to crank on every jackson or flying v they can find, at max volume. Lol plus most of their...

    Looking for advice on a blueprint engine.

    Keep in mind with a 3.08, it may still feel a little doggy... I know a th350 will be a high winder, but may consider a gear change if this is just a street bruiser. Yep! @Heywodja email me and I can send a real dyno from each one.

    Looking for advice on a blueprint engine.

    You are correct. This engine was re-rated a few months back, and looks like we never updated the graph!

    Looking for advice on a blueprint engine.

    I'm late to the game on this one! I have seen pump gas and octane and compression being mentioned a few times, and that's exactly where my opinion lies also. The 396 likes 93 or better. On paper it's only a touch higher than the 400, but it does like 93 vs 91. Some areas of the country, where...

    Black Friday sales. Who’s buying what.

    That's nice! My dad and i kind of "share" about 20 total. So he gets the American strats, and the carvins, and the les Paul's. And I end up with the monoprice, and mex strats, and the harley bentons, lol. Buts it's all good. Even the indio cheap ones are pretty damn nice these days.

    Black Friday sales. Who’s buying what.

    I need a new acoustic amp. I had ordered an inexpensive Harley benton 12 string during black Friday early sale, and want a cleaner sound of a true acoustic amp instead of my fender twin, or g Dec. If you have never been on the thomann website, check them out! Everything harley benton I have...

    Stopping at guitar center tomorrow, and harbor freight, and then getting a hellcat hood on the way home for our charger that my wife tagged a deer with. Somewhat busy day!

    Chevy transmissions break too

    I have broke more gm transmissions than mopars in my life, that's for sure!

    Early arrival gate fee, any other tracks doing this?

    Sounds like when my local track wanted to charge insurance for pit bikes.....lasted about one weekend.

    Headers question

    #1 tube needed cut off and completely moved on my HDK setup, so thats why I was asking if he had a rack. Good call on test fitting.
  20. Johnny Mac

    Headers question

    They look exactly like mine, only mine are stepped to big tubes. You don't have a rack do you?...one tube won't work. I can take some measurements on my fender holes for you. MY holes ended up bigger than I wanted. Hopefully I can help you do a little cleaner job. They didn't have...

    Headers question

    What brand are those? They look like one tube goes through the inner fender.

    Headers question

    I have hedmans on mine. They will step them up to 2.125. I would give them a call if you don't want limited to 1.625 or 1.750

    Enclosed Trailer Questions

    Agree with the above that a 26 or 28 is well worth the extra length and money. I haul a dart in a 24+1 (rounded nose instead of a v) and I would love 2-4 more feet. I can fit a 250 quad in the front sideways with my dart in if for pit riding when racing, and have a cabinet above that, but I'm...

    Racing Harness Recertification?

    You can do that, yes. Or you can get the ones where the shoulder belts meet at a central chassis tab, and bolt that to the roll bar. I have this one. Of course my way is easier with racing seats. Not sure if you have them or not.

    Racing Harness Recertification?

    Camlock every time...latch and link is such a bugger when wearing a helmet...fire jacket, etc. I prefer bolt in also, but that probably depends on cage setup. I typically bolt mine to the original seatbelt bosses / seat bolts. vs the loop types.

    Racing Harness Recertification?

    Agree. Absolute Joke. I haven't bothered paying to recertify a single belt, as it's not worth the dickage all said and done, by the time you can buy another new set.

    Personal Bests

    I'm pretty confident i have a perfect .000 light slip laying around, which was the first pass ever in my dart, where it was a 19.00 at like 65 MPH lol. (stock slant six and 2.XX gears) she goes 10.20s now.

    850 Ultra XP lean bogs when secondaries open

    those ship with extra secondary throttle arms, with various bends, that change the ratio of when the secondary starts to open. I typically go 1:1, and square jet my "big" motors... but i understand for street use that may be excessive. Regardless, throw the 1:1 linkage arm on it, and see if...

    I remember Quaker going to the newly formed AHRA (I think it was) about a decade back. Was defunct within a year, and back to IHRA the following. Hope this one fares better! Wish them luck

    Anyone use the aeromotive A-2000 fuel pump ?

    it might be. If i was doing EFI in the dart, i'd probably go with an in-cell setup, which might muffle it a little more. thats what i'm doing on the blue turd next to the Dart in the video. we'll see if it's any quieter. it's a big old holley double pump unit. But ya, that A2000 is far from...
