SilveradoSS04 Posted December 17, 2003 Report Share Posted December 17, 2003 I was on my way home from the gym and what looked to be about a 1990 Camaro IROC Z Z28 came by me. He was kinda hot rodding it. I got lucky and we got stopped at the next red light. He looked over and nodded. The light turned green and we both went for it. Luckily, I didn't spin as much as usual, and we stayed even untill after 4,000 rpm's and I pulled away. I kept pulling and we let off a little after 60 and I had about 2 car lengths on him. He was I'm not sure how fast those are stock-It WAS a tuned port injected 350-but looked pretty stock. The truck I was driving was my 2003 Arrival Blue Silverado Z71, 5.3, with a cold air kit, cat-back exhaust, 10.4 mm Taylor wires and stock 3.73's. Anybody know how fast those are stock 0 to 60 and 1/4 mile? Thanks Link to comment Share on other sites More sharing options...
Viperkiller97 Posted December 17, 2003 Report Share Posted December 17, 2003 Actually 1990 was the last year of the IROC Z28 . If that car was a 90 Iroc w/ a 350 it should run mid to high 14's . I think the car you raced was a tuned port 305 and that would be a 15 sec. car ... IMHO Nice kill though Link to comment Share on other sites More sharing options...
SilveradoSS04 Posted December 17, 2003 Author Report Share Posted December 17, 2003 Yea, i thought i saw 5.7 but if they ran mid 14's, It was probably a 305. When you say 15's do you mean mid, high, or low? Thanks. Link to comment Share on other sites More sharing options...
Viperkiller97 Posted December 18, 2003 Report Share Posted December 18, 2003 I would say mid to high 15's for the 305 and about a second faster for the 350 Link to comment Share on other sites More sharing options...

SilveradoSS04 Posted December 18, 2003 Author Report Share Posted December 18, 2003 Hey, thanks! I was looking for somthing like that So, what should that make my truck in the quarter? My guess about a 15.2 I don't think it's in the 14's. But if that site is accurate? Link to comment Share on other sites More sharing options...
mwalls54 Posted December 19, 2003 Report Share Posted December 19, 2003 Whats your gear ratio?? i had a 00 Z71 with the same mods as you and i would run low 16s Link to comment Share on other sites More sharing options...
zippy Posted December 19, 2003 Report Share Posted December 19, 2003 well, being a third gen fan that i am, i know a thing or two about the play car. a 90' iroc-z runs an absolute best around 14.4 with a 1LE 5.7 90 camaro. on the other end of the scale, a 5.0 with an A4 and the average driver is a mear high 15's car. they are capable of more, but most can't get everything out of them. with your mods you have around 15.8 truck i'd guess. the one you raced being a standard 5.7 iroc was likely a low 15 second ride with an average driver.

zippy Posted December 19, 2003 Report Share Posted December 19, 2003 is your's an extended cab or regular cab? Link to comment Share on other sites More sharing options...
SilveradoSS04 Posted December 19, 2003 Author Report Share Posted December 19, 2003 Mines an ext. cab. I had a reg cab but then my wife got pregnant So you're saying it's a high 15? That sux. It seems so much faster based on what I've raced and beaten, but maybe not. I've never been to the track. I beat an SS 4 out of 5 times. From a dead stop, it beat me, but from a 20,25,40, and 60 mph jump, I had him by just a hair. It was extremely close, but a win's a win. Link to comment Share on other sites More sharing options...
FwyFlyr Posted December 19, 2003 Report Share Posted December 19, 2003 Had an '85 IROC. 5.7TPI,(5speed) you would'nt touch me... stock. You're runnin' high 15's Link to comment Share on other sites More sharing options...
SilveradoSS04 Posted December 19, 2003 Author Report Share Posted December 19, 2003 I'm hoping to take it to the track this spring. I guess we'll find out. When chevy brings out the reg. cab SS ( 1year from what I hear), That's what I'll be trading for. Link to comment Share on other sites More sharing options...

zippy Posted December 19, 2003 Report Share Posted December 19, 2003 no one had a 5 speed 5.7 iroc stock. they weren't made. Link to comment Share on other sites More sharing options...
Viperkiller97 Posted December 19, 2003 Report Share Posted December 19, 2003 They were not available in a 5.7 with a 5 speed . Thats why it was such a big deal when Chevrolet put 5.7 and 6-speeds in the Camaro . Not to say someone might have put a 5.7 in a 305 5speed car . A lot of guys with Monte Carlo S.S.'s took that weak 305 out and put a 350 in its place .Everything bolts up nice ... Link to comment Share on other sites More sharing options...
