Dave,that was the same thing I thought only I was a bit of a smart a--.
My great uncle use to always say "If it sounds to good to be true it probably is".

Well, just wondering where I have been going wrong on my setups, Erik. Seems to take me a lot more gear and a lot lighter car to hit the 11's.....

My first bracket car that weighed 3,300 with me in it a 454, 12.5 to 1 comp. ratio, mech. cam,4.10 gear ,3,500 stall,would only run at best 11.90's.

I dunno, must be better air and traction in Kansas, huh???? My last 2700 pound Maverick with the 347 stroker never even got out of the 12's, but it did great wheelies if you got crazy with the ladder bars!!!!!!!

BTW Erik, both the BB Ford cars were firmly in the 10's this year. Learned a lot with them on the chassis dyno last spring, Roger and Rodney were both very satisfied with their performance. They're thinking about going to the big bracket race in Bradenton, Fl., believe it's in February??? Non electronics bracket is supposedly going to pay 5K to win both days this year!!!!!

5K to win with no electronics.
Now that is my kinda racing.

Yup, if I could stay healthy for more that a month at a time I might give some serious thought to another bracket car. Some leisurly Sunday afternoons at Thunder Valley might be a lot of fun again....

Only reason I never ran the electronics classes is the double crossover delay boxes confuse the heck out of me!!!!!!

I was pretty much done bracket racing about the time everyone and their brother got the delay boxes.

With one that's not familar with "double crossover delay boxes" what do they pertain to. I've haven't raced anything since 1962 except took my 37 out last year for two passes.

Well, ya better get somebody that actually understands the dang things to explain it.... All I know about them is they are expensive and only work on automatics.... I'm one of the fools that still likes to bang gears, even in a bracket car....... I've heard all the arguments about consistency with a five speed, I guess I've just been shiftin' em for enough years that I manage to maintain good consistency, not counting the first test and tune day in the spring when I have to work all the rusty joints loose in my right arm!!!!

I had a little help from my boss in the setup. he campaigned a t/a dragster with a sbc and a glide. My boat wasn't a very reliable street car. 11.5 comp long rods, dart heads, dynoed over 500 ponies, was nos ready, backed by a 400 with 3000 stall and everything but the interior was stripped. weighed ~2700 iirc, it was 8 years ago when I sold it. I have a friend with a consistant 11 second SS, street driven slicks on the weekends, simple 406 with proper setup. There are plenty 9 and 10 second 5.0s out there, makes my old pos really not that impressive.

Here is a sound clip of my 335" stroker. its in a 1981 GMC Caballero Diablo
its recorded in my carport, bit of an echo, few blasts to 6k. and idle

http://media.putfile.com/soundclip-38

parts used:

400 crank, 350 rods, flat top pistons.
221 @ .050" 471" lift cam 108 LSA
fully ported and polished "416" castings, with larger 1.94" intakes
edelbrock torker singleplane intake with 600 vac. sec. carb
hooker super comp headers 2 1/2" into flowmaster 40's dumped before axle
th400 with 3000 stall convertor
3.73 auburn pro posi rear.

I have only driven the car 3 times on the street, weight is around 3100 lbs. No a/c or any ducting....fiberglass hood.....anxiously awaiting spring and summer to test at track. the car is very responsive, roasts the heck out of the tires 255 50r 15 bf goodrich comp t/a's. Pulls hard above 3500 rpm. The whole car was built on a tight budget by myself, the clearancing aspect must be done with care, especially the bottom of the piston below the pin boss to clear the counterweights on the crank....look for at least .040", and small base circle camshaft must also be used.

Very nice combo.

thanks.....timing was a bit of trial an error.....it likes 16 degrees intial and no vacuum advance hook up.

After-market cranks are available in both main sizes.

or u can use a stock 400 crank(3.75) and have the main machined down to fit the 305 block

Dyno program whered u get that?
