Ya, I know, another dumb guessin game, but im curious

Hey guys, i know the deal of the guess how much horsepower i have game, but i would like to have an idea of what i did to my car.
I have a 305 that i built up with:
H.O. pistons
new bearings,
new rings,
Comp Cam 454 lift 277 duration, (dont know if thats @ .050)
Stock rebuild heads, shaved .020
Holley Street dominator intake (its like a mid rise intake)
Holley 600 4160
Mallory distriburter with high voltage coil
Flow crap headers
Flow crap Y pipe, (hey, those mandral bends on a stock size pipe must be worth something eh?)
Catco Converter
and a good paintjob with a bit of chrome (hey stickers ad horsepower for those honder guys so the chrome must be worth something. )

It runs real strong, i was kinda impressed.I have a T5, and i can chirp the tires in all gears, even 5th. (witch kinda scares me, ive seen 5th gear on a T-5, and i dont think i should be doing that) thats a cool plus.

But i want to atleast show you my lil' 305

i'd say 225-245hp depending on how well it's tuned.

cool. i ran 15.65@92 mph. I think it should be a 14.9er when i get my rear tires and some suspension work done. My 60 foot times were 2.6-2.7
My buddy in a 89 formula with a 350 TPI ran a 15.23 at 88mph, but his 60 foot times were 2.2's
But thats what i get tryin to race on some 205/65 r14's

Thanks

You have times, speed, probable weights and gearing info. Go find one of the calcs online and punch in your info. Why didn't you post those originally?
