1973 Chevy 3/4 454 - 496 build + more

After some thought... considering my current vehicle stock, It came to me that I needed a parts mover, tow vehicle, and completely reliable truck to finish off the rest of my stable.

Thus, my 73 is getting the once over mechanically front to back.

It's a complete #'s matching motor & transmission set-up; so once pulled, it will be sealed up and placed in the corner of the garage for safe keeping!

I will be installing a 496 stroker kit; a 4.250 scat crank, a set of scat 6.385 7/16" cap screw rods, and a set of .030 over KB Forged Pistons.

I just picked up a Gear Vendor unit for the TH400.

Will be rebuilding the rear axle last.

Now, I am looking for some comments on a set of Doug Thorley Tri-Y Headers for this BBC application.
I have a set, but I am 50-50 on keeping the stock cast iron manifolds in place for this truck.
Does anyone have any pros or cons on fit, installations, any adjustments to factory parts surrounding these headers????

I am also considering searching out someone who is making aluminum reproduction radiators. I thought I had seen someone somwhere who was offering these with original appearing GM style Harrison side tanks.

Also, with the Gear Vendor install, anyone have any suggestions regarding these????

I will post as progress comes along...

Thanx guys!
