Gee, that looks tall...

Faithful readers will recall that last week I installed the shine new exhaust headers on the 5.3 Vortec after a little creative work with a touch and ball-peen hammer to clear the steering box and right side upper control arm. The engine is now setting on mounts tacked to the frame, the transmission crossmember is done, but before I weld the mounts permanently, I figured I’d better check to make sure the hood would indeed clear the (high mounted) alternator and very tall intake manifold.

I hung the core support and right front fender, and nervously sat the hood down. In order to have it set down all the way, I had to notch the hoods inner support panel over the alternator, and for good measure, I clearanced the alternator bolt boss on the housing about 1/4″ at the front. The result is an easy 1/2″ clearance between the alternator and hood skin. Hurrah!

Now, I can relax a bit, secure that I don’t have to buy a new, low-profile intake manifold and front accessory drive set up. I do have to get an air conditioner compressor mount, but that’s easy. Now I can pull the engine, install the new oil pan with it’s shallower rear sump, clean the frame and weld the mounts in for good.

It feels good to have it working out!

    You are correct sir! I was dreading having to by an LS intake and front drive, but now I can spend the $$ on an A/C unit or interior kit!
