i think thats all you guys would need, let me know what ya think for e/t, mph along with hp and tq rating

thanks Rob

 

um...... alot [sm=insomnia.gif]

you have a fully built big block. its gunna be fast. maybe someone can be more helpful, but when you have no original components in the motor its very difficult to predict power. you could be anywhere from 450-700 in a big motor like that depending on how things are working together. go slap it on a dyno. im surprised they didnt dyno it after the build just to make sure it was running right.

 

well as far as i know it hasnt been on a dyno, and let me tell you this car fawkin moves too!!

but i'd love to get her on a dyno and see what she hits for hp, and tq....

he ran it at the track, and he said the car ran a 13.6 at over 100mph mark (he cant member the exact mph tho) and he said it was really embrassing as the car spun down the entire track......

 

a worked BBC like that should do well better than 13.6, but if that mph is only marginally above 100 i dunno..... 100-110 is 13 second range

 

yea, but also gotta member he said the car spun the tire pretty well the entire track....cuz it had a 275/65/15 BFG radial t/a which everyone knows they suck lol

now maybe he was full of crap too when he said the number maybe he actually meant like 12.6 or something i dunno.... maybe he didnt even run the car and said he did

 

Um BFG's are not that bad.
