i am wanting to go to at least a single pt88 with probably a 4 bolt flange...i am wanting to know if i can spool a pt88 with the 5.3 and what size exhaust housing i should go with..i will be putting rod bolts and regapping the top rings..i will probably get a turbo cam from Ed Curtis with head studs but other than that it will be mostly stock..i have a PTC torque converter so i hope Dusty will tell me he can spool an pt88 on a 5.3.thanks for any info...........Bob
