2001+ 4.3 deeper bellhousing?
Researching my 4.3 swap, I came upon this
from http://www.novak-adapt.com/knowledge...l_block_v6.htm
Does this mean that an 01+ motor won't work with the AA bellhousing adapter kits to adapt it to an r150f? I'm not really seeing what they mean by crank depth...
In 2001, GM - for the first time since 1955 - changed the crank depth and its pilot bore diameter of the V6. Pilot bushings differ for these motors and transmissions built from this time forward had a deeper bellhousing and different torque converter.

Well, got the engine, bellhousings on the way. Got my fingers crossed that it'll bolt together fine. Hit a small snag with the flywheel too, but that hopefully won't be an issue either.

Anybody got VSS experiences to share? I have my 4.3 ECM out to Brendan at lt1swap.com and I imagine he can just reprogram the computer to accept the toyota sender's signal, but does anybody know what sorta signal it puts out?

New question, for those of you who have swapped a 4.3 into a rig with a digital VSS (non cable speedometer) how did you retain the factory speedo? I'm running toyota tranny and t-case so the stock VSS in the t-case will be there, do I have to keep the factory ECM to keep the gauge functional?

Got the vortec bolted up to the AA bellhousing and everything, test fitted with the tranny in the stock location, and lo and behold theres enough room at the firewall for a second dizzy but no room for any cooling stuff up front. I did a descent bit of reading before starting the swap and my understanding was that the tranny could stay in its stock location but this clearly wasn't the case. If you're attempting this swap as well you've been warned.
