Well today the track had an all day test and tune first pass went a 10.79 by the end of today I got a 10.49 and a 10.48 at 130.05 mph. My 60 ft are not that great 1.55 and 1.56s on 275-60-15 drag radials needs more coverter and gear. but it will work good on spray. I did all runs NA on pump gas with mufflers.

 

sweet, now you need a cage , a chute and a bunch of other safety stuff to spray it into the nines!

 

Chute? Only if you go over 150 mph but yes you do need a bunch of other stuff to go into the 9's.

 

Allready have a certified cage. Just need a license.

according to that 9.99 gets a chute.

 

oh yeah thats right, did you get the side fixed yet? you are the one that got koed at the track right?

 

I took a slide hammer to the fender and door I also used a BFH It's not perfect. But I wanted to race I will wait untill the track shuts down in dec. and have it fixed. I looked on you're link and it says a chute I will have to look in the book I thought 150mph was the rule also.

 

hey with 275 jets, it wont matter 150 no problem, the quick ref. guide seems to be without question , but most tracks let it slide from what i have seen, however i would like a chute back there, it takes a long time for factory brakes to stop one at 135, no less 150. i put aerospace front brakes on, and holy moly its stops on a dime now, at the local 1/8 mile track the shutdown area is 1/8 mile from 115 it was hard to slow enough to turn at the end, after i changed the brakes, i have to let off the brakes and coast the last 100 ft or so, on a 1/4 mile at 146 i made the second turn with ease, and i couldnt even think about it from 130 before. still i will be adding a chute this winter, maybe fall depending on the next day at the track. i have the bracket planed for the teather , and still decideing what launcher to get spring or air, i dont have anything else air so it is silly to do, but lighter from what i can gather.

 

Thats an awesome 1/4 mile time for a pump gas SBC. Can you post more specifics about the combo, cam specs ect? I'm going to be building a 434 in a year or two, my goal is mid 10's N/A on pump gas with it.

 

Need more specs

If I were to build another big inch motor with a standerd deck block I would do a 3.85 stroke for a stronger piston and better rod to stroke ratio. I also would use a little smaller cam dur at .050 I265 E275 with a 112 lobe sep. the rest of the specks the same. This motor just sound nasty when driving at lower RPMs.

 

or build an lsx with 515 inches natrally asperaited, yeah baby, of course there is the fact that it doesnt just bolt in.....
