You can always use an aftermarket throttle body, like the FAST units.. Same bolt pattern, available with a cable bellcrank.

The Corvette LS1 is DBW. I am sure a conversion could be done but you would need to run some wiring and program the PCM as well. I do miss the DBW from my Vettes, I felt that it was more responsive than the cable method.

There's two modules you'd need to acquire, related wiring harnesses, and of course reflashing the PCM as a 'vette ... Once that's done, I'm not sure your BCM, dash cluster and radio will still operate properly.. Sure is a lot easier to just get the right throttle body to begin with ;)

Personally, with the occasional "freaking out" of the PCM's reported here, I'd be a little skeert to let it run my throttle. :eek2:

Actually, the LS2 intake will fit on the LS1. Some may want to wait for that option. There is an article in Chevy High Performance mag discussing the LS1/LS2 part interchanges...specifically, the throttle body swap and use of Ls6 heads.

Would much rather have my foot actually open the throttle than the PCM. :rolleyes: Computers fail

From what I've read, the LS2 intake offers very little over our LS6 intakes. You can always put a larger throttle body on the LS6 intake. There's also a couple of companies making adapters to fit our style throttle body on an LS2 intake. There's a lot of good info over at LS1tech.com on LS1 vs LS2 conversion.

My Silverado had DBW and I hated it.... For me and I might be a Gump if I didn't have my heal resting and went over bumps it would bounce my throttle. I like the feedback from a cable because DBW felt too much like an arcade game....
Just my 2 cents (She took the rest!)

FYI, the LS2 intake WILL fit but the TB's are not interchangable. Different bolt patterns.

So until someone on the aftermarket comes up with a replacement, an intake swap won't work on an LS1/6.
