i have the 3.4 pulley, ported heads/sc/tb, tb spacer, tb heat shield, 3in catlees dp, fwi, msd wires, now a 160 thermo and it runs a whole lot better. but it needs to be tuned bad. i just got a trans out of an 01 le sabre, non hd, which means its a 2.86 gear. so its no shifting right. once i put the hd diff in then it will be a 3.29. im going this thursday to indianapolis to PRJ performance to get it tuned.
