Answer 1

I am no longer in the business, but I can answer anyway if I may. I remember when those came out, and I read that the buyers were disappointed in the performance, however, with some tweaking and addition of a chip, exhaust headers, better muffler/s, etc they woke up and RAN.

Answer 2

Sorry to disappoint you, but no its not particularly fast. GM shot themselves in the foot on this one....had incredible potential, but they used a very torquey RV motor with round or "peanut port" heads. And no, I do NOT mean oval. Would bounce the passenger's head into the back window from a start, but ran out of breathing by about 80. Mine was a 90 and came with the 400 trans (3-spd). After a 2/4 drop, it would handle extremely well, and after a 502, finally had the power to back up the image. Weak spots are not the trans, but instead the weak G80 diff. Plan on replacing it if you are going to make power.

Answer 3

The 1990 is not all it advertises to be. To answer your questions specifically:

The 454 was used from the 3500 models ( one tons) . It wasn't until 2003 that they got an LS1 version.

They are collectible though. This version was only made for 3 years at around 16000 units total.

They are beautiful to look at.

Answer 4

Consumer Guide said the acceleration was very good, and that it threw them back in their seats. And after all, it IS a 454 w/ 255 horsepower and quite a bit of torque, in a 1/2 ton, 2WD, shortbed truck. So yes, it is pretty fast.

Answer 5

really fast truck if got the LS1 VERSION motor they are hard to find won in good shape that hasn't been wracked from loss of control the only weak Link in them is the auto trans they didn't hold up so if you find won check the trans more in likely it will be going out or been replaced good luck

Answer 6

i own a repair shop,and that year of truck is kind of rare to come by,and yes there pretty much what they should be,fast and power full also,,but there wasn't that many of them made to start with,so if you find one ,,you ,had better buy it,,any good price on finding one of these is a good buy,,i got a friend who has one,,and wont drive it,,he,s saving it,,but if you look you,ll find one,,you might have to pay dearly for it,,but their worth it,,good luck,hope this help,s.,,have a good x-mas.

Answer 7

it quite is unquestionably thinking out of the field!!! What an astounding suggestion. on the middle of your suggestion is the shown fact that "Detroit" ought to build automobiles human beings desire to purchase. the government ought to get out of ways of the motor vehicle makers and eliminate regulations they have positioned on them. controlled financial ruin could paintings the terrific for the "large 3". examine Mitt Romney's Op-Ed interior the manhattan situations (approximately 2 weeks in the past) and he lays out a suited plan to maintain the motor vehicle industry. i will hearken to the rumble of those astounding V-8's as I examine your question. P.S. astounding %!!! i admire President Reagan. we want yet another Reagan.

Answer 8

There are high performance big blocks and low performance big blocks that make lots of torque for pulling, the one you are referring to is probably the torquey dogster.

Answer 9

the ss is just trim level and alloy wheel/tires. there is/was no engine hp increase. it possibly would have had dual exhaust, though. geez. thats been 17 years ago. kinda hard to remember exactly.
