I am getting ready to take my DD/towrig to the track to see what it will do on Friday but wanted to see if anyone here has a ideal of what it will run.The truck is a 1988 Chevy 1/2 ton 2wd.The truck is lowered 3 1/2 in the rear and 1 1/2 inches in the front.
The motor is a 350 out of a 1993 caprice cop car.I rebuilt it.Its bored 30 over and is basically a stock bottom end.The heads have a three angle valve job and had a clean up mill done to them.The valvetrain is the factory hydraulic roller setup.The motor only has 300 miles on it.I am going to run 93 octane gas and advance the timming about 14* for the track.It has a knN airfilter and a TBI power charger.
The exhaust is stock manifolds y'd into a single 2 1/2 inch pipe (no cat) to a super 40 series flowmaster dumped before the axle.
It has a 700R4 transmission with a BnM transpack on the street/strip setting.
The rearend is a 8.5 inch 10 bolt with an open diff a richmond 3.73 gears.
So does anyone here have an ideal of what it will do?Thanks

 

15.2 is my guess. but i dunno what type of power that motor is putting down.

i'll guess that you'll spin like a bastard off the line though.

 

16.1 is my guess.

 

high 15's/ low 16's

 

I believe that is an LT1 isn't it? Should be capable of 15's in warmer weather, with a baby converter (2k) and enough tire high 14's in cooler weather. Don't be dissapointed if it doesn't run great now, its just too hot. Sounds like a great combo and should be alot of fun!

 

Thanks for the guesses.I wish i would have put a LT1 in there but it is actually a TBI setup.I am really just hopeing to be in the 16 second range.I believe i read somewhere that with a stock truck like mine they only went a 17.8 so i an hoping to shave a bit off that time.

 

LT1 Caprice was 94' - 96'.

 

Thanks Zippy...hate it when that happens.

 

Well i had a little extra time after work and decided to hit the track today for the test and tune.Heres what my best timeslip says:
R/t .198
60' 2.354
330 6.682
1/8 10.335
MPH 67.12
1000 13.508
1/4 16.206
MPH 83.65

I still need to get my alignment done because the truck pulls to the left and the front wheel are toed in a little.I believe i will pick up a mph or two there.And i plan to add longtube headers and a true dual exhaust.With all that done and some more seat time i believe it should be in the mid-high 15 second range.
