- 2800 stall converter - 3.73 gears - drag radials - 1.7 rockers w LT4 valve springs - long tube headers - muffler elims - cut lid w K&N - tune doing the above should net mid - low 12 sec timeslips. add a hotcam and some head porting and 11s should be easy

the previous owner did the following to the car: - hotcam - tune - 5 angle valve job - port matched intake - 160* stat - muffler elims - cut filter lid - TB bypass with the stock 95k mile clutch and a set of worn-out, 3 year old BFG DRs i mananged a 12.2 at 116mph with a 1.96 60ft just got my...

my LT4 is only a weekend car/sunny funmobile. taken to the dragstrip maybe ten times a year or so. on weekends im out cruising for races, but so far ive yet to find anyone willing to challenge the old C4 my daily driver is an 05' Sunfire 5speed. gets 26/36 mpg. boring but practical

my LT4 has the stock exhaust system, save for muffler elims, as well as the hotcam and a tune. the car put down 344rwhp and ran 12.2 at 116mph in the quarter

beat my old time this spring... car ran a 12.2 at 116mph with a 1.9 60ft later this summer, im looking to do flywheel/clutch/shifter/drag radials and see some 11 sec slips

nice! someone finally responded. i was beginning to think no one on this site raced their LT4s went to cecil county dragway on a Saturday morning in mid Nov last year and got a traction limited 12.74 at 114.11mph. 60ft was a pathetic 2.19. looks like my mph guesstimates were pretty accurate...

i just picked up a 93k mile LT4 about two weeks ago. the car had some minor things done to it: cut filter lid, 160* stat, port matched heads and intake with a 5 angle valve cut, and muffler elims. a hotcam and tune complimented the basically stock setup. the car made 344rwhp in this form a...

heres what i did to the 89' to run the 13.1s FREE MODS: - cut filter lid - removed EGR walls from plenum - bumped timing to 9* BTDC - removed water pump "frisbee" - adjusted TPS to .60 volts at idle - gutted cat converter BOUGHT MODS: - K&N drop in filter - Hypertech airfoil - Holley AFPR (set...

the standard replacement AC Delco platinums

took a trip to Xotic Motorsports today for some dyno runs in my bone stock 93' LT1 6speed 40th anniversary Corvette. made 2 pulls, the best of which was 266rwhp/306rwtq. dividing by .85 for losses through a manual trans and that gives me outputs of 312hp/360ftlbs! thats 12hp and 25ftlbs over the...

i bought a 40th anniversary Corvette about 6 months ago. it has the ZF 6speed and 3.45 gears. 71000 miles. about a week after i bought it i changed the oil and headed down to the dragstrip to see what it was capable of. i had absolutely NO previous experience racing a manual trans car before i...

i installed just a crank pulley on my L98 Vette and went from a best mph of 103.79 to a new best of 104.73. judging from the trap speed increase i got about 10hp out of it. there has been no cooling issues (maybe thats because of my 160* stat that keeps the temps really low anyway), and the...

awesome numbers! if i get anywhere close to that on my stock 93' 6speed ill be doing backflips!

heres the complete list of my mods FREE MODS: - cut filter lid - throttle body bypass - removed "frisbee" - ported plenum w siamesed runner openings - gutted cat - timing set at 9* BTDC - cut back spark pugs - mufflers eliminated BOUGHT MODS: - K&N drop in filter - Hypertech airfoil...

i dont know what brand of pulley this is... i bought it used. i think all of them are about the same anyway... most are about 22% underdrive. im only using a crank pulley, no alt or water pump pulleys. charging is not really an issue... the volts get a bit low during idle, but as soon as you...

last month i baselined my current combo several times at our local track. best timeslip read: 13.16 at 103.79 w 1.76 60ft since then i had some problems with my car that resulted in the replacing of the MAF sensor. that set me back about a month. so after i fixed the car, i installed the crank...

my brother bought a 91' about a year and a half ago. when it was 100% completely bone stock he ran consistant low 14s with it. his best was 14.0 at 99mph w a 2.0 60ft. his car was an auto w 2.59 gears

hey Mic, whats up? thought you had fallen off the face of the earth! the 40th is a blast to drive, the 6speed is so much fun! its really in great shape... now i just have to tune her and itll be running right with the 89' speaking of which, my TPI Vette is barely running. the bog i was...

thanks! the 13.1s were on DRs though... if i had a set on the LT1 Vette im sure my times would have been closer to what the 89 is running. all in all i didnt think my times were all that bad considering that night was the first time i had ever launched the car from a stop and ive only been...

just bought the car about 3 - 4 weeks ago. its a 93' 40th anniversary coupe (ruby red/ruby red) with the SD LT1 and ZF 6speed w 3.45s out back. ive owned nothing but auto cars since this one, and i can say driving a manual trans is AWESOME! however, since im new to the stick thing, im not very...
