Just bought a new Radiator. https://www.ebay.com/itm/1968-1979-F...RZFdxV&vxp=mtr

Picked up a junk yard front core support. My original one had a little bit of rust in the one corner. The new one is a galvanized one with the larger radiator opening. This radiator will fit in there nice and the inlet and outlet should be close to right. should easily cool that 300.

Plug up any gaps between the radiator and the core support if the core does not fill it fully.

Right, After measuring last night it should fit right in. Going to put electric fans on it. Not sure if i should just buy some online or try to find a good one out of a junk yard. Know a lot of people use the Taurus Fans. And their alternator. haven't found a 92-94? Taurus to pull it from. Found the alternator new for around $70 but doesn't come with any of the wiring harness. Need to look again tho. Any suggestions appreciated.

Ive ordered just about all the necessary parts for my Holley Sniper 2300 swap. Doing some underbody painting prior to starting in on the motor. Picked up a 130amp alternator and need to go back for the Taurus electric fan.


How do you like my bed lift.

Just one suggestion. If you don't have one, install some kind of spreader bar ( Or a tailgate ) at the rear of the box. I have seen the bedsides buckle in on a couple trucks lifting the box that way. Something to keep bedsides properly spaced in the back is just some cheap insurance.

Good point! Itís a very solid bed. But I just went over and lowered it down on some tires. Want to flip it over when I can get the help.

Question:

Took the truck on a short test drive yesterday. Sniper ran great. At 60 mph I was running 2300 RPMs. I've been considering changing my tires to something slightly bigger. It currently has 235/75r15 on it. Thinking about Firestone Destination 30/9.5r15's.

Truch has a C4 and 3.0 gearing.

So with mpg in consideration would increasing the tire size to lower rpms improve my fuel consumption with the added weight of the larger tires?

the 235's are @ 29lbs - measure at 28" on the truck
the 30's are @ 35lbs. I know rolling weight plays a big factor in mpg.

I am of the opinion that the increased inertia and rolling resistance, increased aerodynamic drag, increased intake manifold pressure and reduced braking capability will more than offset any fuel economy benefits from the reduced rpm.
