Eagle85C4 said:Unfortunately that is a problem. The ECM in the 85 has a 160 baud rate , the next upgrade is to one that has 8k speed and needs rather extensive rewiring to make it work...the following site has a ton of info concerning the swap....it is for a Z28 but you will get the idea. Actually you will see that the Z has the same ECM as the 85 vette and the upgrade requires changing the connectors and some repinning as well as getting a new eeprom for the newer ECM. It looks like a decent winter job...good luck...

LD85 said:yes I am putting the 406 in my car, and have decided on the minram setup with the TPIS 409 Cam with retro rollers and stamped roller tips,, all from TPIS.
LD85 said:Jeff, will they fit under the valve covers or do I need to mod the valve cover?
Also, do you know of anyone running the 409 TPIS cam on an L-98?
