I have 89 Buick LeSabre Estate Waon 307 Olds engine :<( and want to improve it for 2012 Hot Rod Power Tour... What sway bars improve lean and basic handling Any shock recomendations - like Bilstein, Monroe, but... Exhaust system changes? I know this engine is bad source of power, but I need to run it for three more years due to emissions - any recommendations for exhaust, EPROM etc that will help this survive 4000 miles of HRPT? How about experience in LS series in this body? 5-6 speed changeover? Instead of LS, how about a 400, 430, 455 backed by the 200R4 (built up, of course) Like to see a red block under that hood! :<) Other recommendations? TW: How do I get off vinyl 'wood paneling' since a good portion is bad and I don't know how to improve / repair.
