TTI headders vs Starter vs torsion bar
I am using the truck starter that came with my 5.7 engine and 545RFE trans.
TTI header clearance is super tight in multiple places including torsion bars, steering box, passenger side frame rail, brake proprotioning block.
The best solution for me was to thicken the driver side engine mount. I'm using the 72 down TTI mounts and the cheap rectangular isolators.
I'll see if I can look up the starter p/n and snap some pics.
