If fuel economy is a big concern, this is probably the wrong hobby. lol.

The reason I asked is for my own benefit. The only way I know how to build a project is with the intention of driving it every day.

i have an M715, a fullsize military variant of the J-20. it is modified and rolls on 40"s. a fair bit of custom trickery on it if one cares to look. most common question i get by FAR. "what does that thing get for mileage? i bet its horrible". whiskey tango foxtrot? if i was concerned with mileage would i be driving a vehicle that has more flat front surface perpendicular to the ground than a Kenworth? would i be running a 454? i dont understand why that is so important to people.

hope the old man is enjoying his truck! it sure looks nice.

Got the engine all buttoned up. Gotta finish up the transmission and transfer case next so I can drop it all in the chassis.

I decided to go with a 1990 K/5 Blazer fuel tank...for a couple reasons. 1) It has a 31 gallon capacity, and since it's a lifted longbed, the extra size of the tank is a non-issue.
2) Those blazers came with TBI engines, so the tank is already baffled and set up for an in-tank pump. I am just swapping a higher output pump in place of the 12 psi TBI pump.

Took the stock sender/pump bracket and cut it and welded it last night. The 3/8" feed, i was able to use my 37* AN flare tool and flare a tube nut onto that line. The 5/16" return line was a little trickier, so I cut up a steel JIC fitting and TIG'd it to the return tube. I also welded the evap tube closed, as well as the tank vent. I was planning to rely on the vented fuel tank cap, but I might cut the plug out of the vent and run it after all.

Should see some real progress soon, but in the mean time, I picked up a FWD LS4 5.3 for the heads and some other goodies to complete the L33.

Ok I'm way behind on this one. I was under the impression that the l33 heads were the same as the ls4.. am I mistaken?
