Gen III conversions

It sounds like the same project I'm looking at.This is what I have come up with
*the overall length is 24 " 1 " less than a small block chevy
*harness available from Painless $500 + use OE ECM
*great availability
*carb intakes are available from FAST
*bellhousing is the same as a small block so transmission option are the sky
*4.8/5.3 are aluminum head cast iron blocks
*5.7 LS 1 are aluminum head and block
*6.0 can be cast iron heads or aluminum.WARNING the aluminum heads on the 6.0 drop valve seats on a regular basis.Cause is due to not enough press fit on the seat OE .002 need around .006
* last the early 1999-2000 GEN III engines have bulletins in regaurds to piston slap due to the short piston skirts.The later years graphite coated the skirts to eliminate noise.So I would shoot for a later application.Some of these also have electric throttle control .As in no cable .I don't know if this harness is availableas of yet.I'm going to use the OE harness.Good Luck
