Sold my Corvette

Just purchased a 1995 Impala SS and I am hopping that this is the correct site to get Performance Upgrade information. Please reply if you can assist me.

I don't have much to offer you but I can tell you that the intake manifold and heads are major choking points on that LT-1 motor. If you want to get serious about it's HP, and I'm guessing that would be 400hp or more,...you'll need to address those parts.

Otherwise, it's game-on like any small block. Free up the exhaust with headers, free-flowing cats, true-duals, get a newer intake/air-cleaner setup and a small cam or ECU upgrade. I'm sure you'd prefer some better specifics but I've not done an LT-1, just read about others'.

Thumbs up

Great car. I had a '94 model. Bought it new and nobody knew what the hell it was the first year. Drove it 10 years and put 120k+ on it until the engine blew NASCAR style @ 85 MPH. Found another low mileage '94 LT1, swapped it in and sold it for $7,000. They still hold their value pretty well.

Those motors are pretty easy to pep up. Cam, decent set of heads and your on your way (intake isn't THAT bad, TPI guys swap to the stock LT1 intake all the time). But like BA said depends on your power goals. I would also look into the Delteq coil pack conversion, works better than the optispark and you wont have to worry about replacing the opti everytime it goes. Get a good set of headers, exhaust and look into a blower

The common upgrade is to use LT4 parts.

Same engine designation different engine. If you wanna go that route, LS6 has been around since 70', used in the Chevelle and then later in the Z06 corvette (different engines completely).

Agree. Kind of a slap in the face to call it an LS-6 to me. Kind of takes away the mystique of the original. At least the newer version LT-1 shared the same small block heritage.

Well I don't think they used the "-" so that's supposed to make it ok lol. LT-1 versus LT1 and LS-6 versus LS6. Stupid?..yes But what are you gonna do. I myself wouldn't consider it a slap in the face if you look at it from a performance stand point. Both engines (LT1 and LS6 for that matter) were the hottest of their kind in their time (LT1 for small block in the early 70's and the LS6 for the big boy, same with the newer version).

Ok, To steer this back to the original topic, a super cheap, very noticeable upgrade would be a set of 3.73's out back. The stock unit has 3.23's I believe, It makes quite a difference for cheap. Just be ready to replace the posi clutches. For whatever reason, more than a few people noticed their posi go out after the gear swap. Go figure.

Don't listen to me, what do I know? I've only been doing this for 30 years.
