Old Iron 2.0

It's 100% not a "Vortec". Chevrolet went to center bolt valve covers in the 80's. A Vortec head only has four intake bolts per head, not six like those. A Vortec head does not have an exhaust crossover. A Vortec engine would have a plastic timing cover with a cam sensor. A Vortec engine would have a roller cam.

That is an LO5 350 TBI (or an LO3 305), from an '87-'95 truck. A car would have a roller cam.

Thanks for the info! So I can bolt up a regular SBC intake to these heads?
 
I'm gonna toss those 52's on and see what it's looking like.

I don't want a big gay truck. I'll post some pics when I get them bolted up.
 
Gotta BE like Larry bro, lol with the FI.

FIFY

Summit wants $600 friggen bucks for that Dart carb intake? You got to be insane to go for that. By the time you covered the cost of a carb to feed that giant and a good dizzy you are right back into the FI territory again. All you need is a PCM and a stand alone harness to make that 8.1 run. Just saying, but I wouldn't go through the bs to retrograde an 8.1. I'm not counting the fuel pump as you'd need one anyway to run the carb as there is no fuel pump provisions on the 8.1 for a mechanical pump.

And I'm gonna throw these 4" 52's out up front and see how it all looks.

My clapped out stock 52's up front are netting me around 4" of lift. Probably gonna put them on the weekend of the 7th.

With the 4" lift ones I'm gonna guess maybe 6" or so, I don't think I'll be sitting at 8" of lift with those up front especially when the 8.1 goes up there and a winch at some point.

I'm also running 2.5" 52's plus a big block and winch, I'm dead on 7" with a Zero Rate.
 
Got this for free today. Don't know much about turbo stuff or what size this thing is but it is new...

Might work well with the 8.1 if I can figure out how to fit it up.

Least on the priority list though.

Sell that turbo to someone who needs it.

Yes, you can bolt an early intake manifold to those TBI heads, but you have to modify it for the center two bolts on each side.

What specifically needs to be done to the intake manifold? Holes need to be enlarged or what?
 
Put those 4" lift 52's on. Removed the overload prior to installing.

Truck does sit higher in the front than the rear but I'm 99% positive I will be able to level it out with an EZ-inch, 1 or 2 extra leaves added to the 64" springs and fixing my shackle angle in the rear since its kicked to the rear a lot.

I have 7.25" shackles that I can use in the rear too. I know that would only add about half an inch over the 6" shackles but I may go that route in addition to the other things mentioned.

Moved my shackle flip to the rear a little bit and threw the 7.25" shackles on.

Got the shackle angle set to where I want, everything is just clamped on for the time being. Have to get some new bits, burnt my only 7/16" HSS bit up and all my 1/2" bits are trashed.

I'm just guessing here but I would like to say I gained 1.5" - 2" of additional height in the rear with those two changes. I think an EZ-Inch will get me level at this point.

Thinking about replacing the 7/16" bolts in the flip with 1/2" bolts while everything is apart.

Also thinking about going out again and dropping the front axle to get the leaf springs swapped around. The 60 is sitting crooked under the truck and I'm thinking that there is a slight offset in the center pins which is causing the issue.

Gonna put poly bushings in the springs while they're out... I have enough sitting in the garage to bush them so why not.

Going to move the front spring eye forward 1 more hole in the B52's, at that point they will be in the forward most hole.

My shackle angle up front will be a little more vertical (currently kicked back to the rear) and my axle will move forward just a hair. I'm thinking it may drop the height in the front down just a hair too, I'm guessing 1/4" or so.

Here's my shackle flip relocation template lol.

Worked well!

Frame was crusty in the area I was working on so I wire wheeled it and shot some primer on it.

Got my x4 1/2" holes drilled on each side and all of the holes in the shackle flip punched out to 1/2".

Still need to drill the 2 holes on the bottom flanges of the frame rails.

The rear most crossmember is gonna need some clearancing done.

No one in town has a 17/32 bit. Gonna order one.

Some of my relocation holes were a count hair off, I can persuade the bolts in but I would rather knock the hole out just a little bit.

Working on the front end today, planning on hooking up the steering shaft too.

Picked up some chrome SBC valve covers for $15 this morning.
 
My local fastenal has a fair selection of bits, maybe try them?
They probably carry them here too. The thing is that all of the fastener stores that I know of are closed Saturday and Sunday and I usually get off of work after 5 P.M. on the weekdays, by the time I could make it to one of the stores it would be closed.
