YOU ARE CORRECT! One of the only GOOD things GM did with the C4 other then the D44 rear.

Those L98's were rated somewhere around 340tq... 0-40mph feels just as quick as MOST sports cars. They are torque'y motors and you cant kill em.

Good buy! Looks fun!

( Oh yeah and getting out of them is a PITA but you get used to it

Im sure the convertible helps in getting in and out... )

Tons of low end torque which makes gunning it outa stop light fun, it also makes it easier to drive smooth. And yes its kinda hard to get out of but I'm 5'8 135lbs so it isn't that bad.

Yea, the '89s were rated at either 240 or 245hp and 345tq (and that's @ 3200 RPM). Pretty sure the vette's were a bit under rated because the '89 IROC was also rated at 240/345, and the vette had the advantage of better flowing aluminum heads. Great street motors, and a few tweaks to the TPI setup will help them breath a bit more and give them a little bit more top end.

My buddy just did a decent amount of top end work on his 91 vette (thats the L98 but with the LT1 bumpers). cam... ported TPI and some other stuff and it dyno'd some impressive numbers.
