Big Block Drift Truck - Pic Heavy

[bba952]

did some work on the heads today while i wait for the coilovers to come in. i will be using the stock 7.5l EFI heads, and exhaust manifolds. They where working fine when i pilled the engine from my F350 so im just going to do a deep clean, replace the valve seals, and lapp the valve seats.



Here is my valve spring tool i made today. the scrap pile saves the day, again.

i dont know how many miles where on the engine, but there is some carbon build up on the intake valves.

I found a "Repair" that the previous owner did. they stripped out one of the exhaust manifold bolts and decided to weld a stud to the head. i found this out after i tried to remove the stud and part of the head came off with it. i guess i will only use 7 out of the 8 manifold bolts.

After 30 years of use 2 of the intake manifold bolts were also stuck so i had to add some heat to remove them.

I know it's cast, but a good welder could fix that right up... Whether that'd be more cost effective than a PnP head or not is this question.

not using the bolt wont make a difference cause im using the stock cast exhaust manifold. I can weld the material back in place and make it look good but i dont have the correct sized drill bit or tap. spending $50 on a tap to fix these heads isnt worth it for me. if it was a performance or rare cylinder head i would, but its not. most people who are building a 460 throw them in the scrap pile.


and im cheap lol

Decided to make new cab mounts. the ones i made the other day just dont look right.

cleaned up the cylinder heads and threw on some paint, which kinda hides the fact that they haven't been machined in 30 years. also added the hood pins, just have to get some rubber stoppers to level it out

lipstick on a pig!

Im not sure how long the paint job will last, but it made this engine look 100%. still waiting for the valve seals.

going to continue working on the aluminum intake. I had to weld up the injector ports and some unneeded vacuum ports. This was the first time i decided to aluminum stick weld and it was interesting. I have a couple of welders but not one that can AC tig and i didn't want to buy one (i don't weld aluminum much). you have to feed the puddle a lot faster and a 5 pound box of rods don't last long.

drew up a 3d model of a carb adapter for the stock efi 460 intake. going to 3d print a test piece tomorrow.

relocated the rear crosmember to make room for the axle housing. before therr was only about 2 inches of clearance.

Here is the prototype carb adapter. next i need to have someone CNC machine it from aluminum.

Here im trying to make the front bumper more modular and simpler to remove. I started by removing the stock bumper and removing all the support brackets on the sides. im goin to fabricate some new brackets that will also serve as a jack point directly behind the stock bumper.

the next step was shorting the front frame rails.

Then i made some end 1/4 end plates where the new bumper brackets will bolt to. welded inside in out. not sure if i will end up boxing the first 6 inches of the frame.

Can't wait to see this thing wreck some tires

Should I run a roll pan??

The truck will spend most of it time on the track drifting. I dont want to spend money on a roll pan, then spend time installing it just for it to be wrecked at a drift event. But the rear looks kinda empty. suggestions?

 

[SenorNoob]

Make one?

 

[Briansshop]

Looks fine without one IMO.

Piece of tube to fill the space?

I'd probably get a small length of aluminum sheet and put a simple curve in it, like a lazy roll pan
