Re: post em up....
 

Wow! If you ever brought that thing to my neck of the woods....we could make some money at the track.....that goes for most of the quick guys on this board tho. Do you have any idea how many jackasses there are here that think a truck can't do it?

Re: post em up....
 

How far did you spread the LSA out? Mine is 110 installed at 108. When I freshen(if I'm still running alky) I am going to widen it to atleast 112...maybe 114.
I'm running a 9" spragless converter..I had an ATI 8" but at it's tightest it was going 6800 on the brake. The new one is 6000

Re: post em up....
 

Yea...I hear ya.....I know some guys here running the AFR's and they are really pleased with them.....but they are not running the as cast head either. You are not the first one to tell me that I should go Brodix....in fact, several sources have brought it up.

What is the difference between the BB2X and the BB3extra? Those are the two I hear about the most....just haven't really researched it yet. I guess what I will end up doing is finding the best head I can for what I want to do....my goal is still to have an off the shelf head, unported and pump gas compatible. I don't care if it drinks 5 gallons a mile.....it needs to be barely streetable on pump gas.

Also, an update......the 496 short block should be ready in about a month. It is now being machined, checked and will assemble immediately after. It is using the SRP 212157 dome piston. About 10.6:1 with a 112cc head. Stay tuned...more to come on project 496.

Re: post em up....
 

I like my AFR's 345 CNC chambers as cast port

Re: post em up....
 

The bb2xtra's would probably be better on a 496. I bought way big knowing I would stuff it full of nitrous till I could build a bigger motor!

Re: post em up....
 

I will look a little closer at those heads and may change my mind on the head.

Re: post em up....
 

I went from a 113 center to a 116 center . The first cam was advanced 1 degree and the current one is srtaight up . I set my cams up at .050 lift becuase you dont get an accurate reading on a non symetrical lobe when you use the normal method .

Re: post em up....
 

116...? You running squeeze on that boat? I think my builder went too tight on the LSA. I would love to "just" swap out cams to do a back to back trial, but if it comes apart that far...it's going from a 540 to a 565

Re: post em up....
 

No I havnt had spray on it since 1989 . I was trying to get more mph . Like I said I just missed it . Oh our trip to track didnt go to well we had a constant 20 plus mph headwind . The track was also marginal at best . The two passes I made I was out of the groove .Could only go 5.77 @ 121 and 9.05 @ 147 . (I can run more mph an the stop)One buddy of mine with a Camaro was 2 tenths and 6mph slow and another with a truck was 3 tenths slow so I guess this thing will run 8.80s .

Re: post em up....
 

How much do youusually pick up on the back half? Looks like you picked up 26mph on that pass. Thats pretty good with one of our barn doors. I'm about 23-24mph

Re: post em up....
 

Interesting Jim. I would have thought you would pick up a bit more MPH than me in the last 1/8.. Last time at the track I went 89mph in the 1/8 with 110mph on the big end (21mph). My recent late night solo farm field test showed 93mph 1/8 and 116mph (23mph). I know it's not the track timers on the last one, but the Gtech was with in .1 and 1mph on a bunch of back to back track passes.

Re: post em up....
 

I was just looking at my last pass of of last year.
60'-1.35
660'-6.07 @ 112.47
1320-9.60 @ 138.31

so I picked up a touch less than 26mph...I was still tuning most of last year

Re: post em up....
 

Change your sig :) Still says 9.95 @134..

Re: post em up....
 

I hope to be faster the first time out this year....I;ll wait til I get the 5.9x sub 9.50 pass

ET no idea. Planning a truck shoot out in Temple, TX this summer.

Re: post em up....
 

Looks sweet but I would go atleast 3.42 or add a little spray!

Re: post em up....
 

I usually pick up 30 to 31 in the back half wide open or on the stop . Normal back half et on the stop 3.32 to 3.35 , w/o 3.22 to 3.25.

Re: post em up....
 

oops I meant to quote bigjim

Re: post em up....
 

Yea, I'm finding out the 3.08's are not going to work very well. I'm looking for 3.42 or 3.73s. I may end up with 3.73 because I want to keep the 12 bolt. Pull strong but a little more gear will tear up the tires better. :metal:

I'm guess 14's with traction. What da think?

Re: post em up....
 

you should be able to do that!

Second two pics are how I am going to try and combat the traction issue.

How much time do you think I can shave with the slicks and the bottle?

Re: post em up....
 

sqrbdy that's a sweet @ss ride the slicks should help a bunch!

Re: post em up....
 

What's the deck height and the bore and stroke! Sounds like what I want to build!

Re: post em up....
 

Pulled a 12.91 1/4 et tonight. All throttle no bottle. Next trip out I'm gonna juice it!

Re: post em up....
 

What was the new mph? 105ish? How about your 60'?

Re: post em up....
 

105.60 mph and I missed 2nd gear. I ran it up to the rev limiter and left it there it seems like forever then I shifted. I just installed a Hurst Promatic 2 Ratchet Shifter and I was excited about the launch and just forgot to shift. That annoying orange light on the tach should have gave me a better inidication that it was time to shift :lol:. Oh well it was only my second time in my life to go to the track. I think it will get better with more experience.

60 ft was 1.79

reaction time was 1.0095 (I know I waited to long but I had to finish my sandwich :lol:)

Re: post em up....
 

cool! Seat time is your friend.
! Try leaving on the bottom yellow!

Re: post em up....
 

sqrbdy, love that color, very nice truck!!!

Re: post em up....
 

Thanks for the compliments. I am really loving this truck.

Oh yeah, and this is justy an absolutely fantastic forum. There are just a bunch of very nice folks on this board. Some of the previous hobbies I have been involved in the people seemed snobish, that is clearly not the case here.

Re: post em up....
 

Thanks for the props on the board! I have been on several boards and this one kicks all their @sses!

Re: post em up....
 

man if you can get traction and get the shifts and reaction times dialed in...you can be in the 11's with no bottle.

what hp numbers are you runnning

Re: post em up....
 

Was that at Evadale ?

Re: post em up....
 

yes.

Re: post em up....
 

how do you put pictures on this sight again.?

Re: post em up....
 

They have to be small but you can hit go advanced then manage attachments browse for the pic then upload. Or if they are hosted you can just post the link with img at each end!

Re: post em up....
 

Well....guys. I had to scrap project 496 for now. The machine shop found two cracks in the block and the rods are trash as well. I have already picked up a new set of rods but I am going to pull the plug on it right now. Pretty bummed about it...

Re: post em up....
 

buy my 468 short block!
