ill figure something out, but i think i want to ditch the stock stuff either way. it'd be real nice if i could use a 24v intake plate. that would put the inlet one set of bolts farther forward and totally fit perfectly. but then i have to redo all the injector lines, and that sounds like a bunch of poo

I want to say someone else on this board has a 24V intake plate on his. I do like your idea of building something custom. I can only imagine how BA it will look

If I remember correctly, the 24v one won't work because the 12v injection lines interfere with the intake hole.

Re: 72 k20 project

What if you turn the intake plate backwards? Does that offer more clearance with the hole in the back ?

Re: 72 k20 project

i certainly could, but there is no need. it clears everything just fine. i was just joking around about pulling the AFC since it would be far from a daily driver/tow rig if i did. it would be pretty hot and not need to worry about low boost fueling. not good for the current plan.

i've found that it helps bleeding a HB system if you can crack the lines at the booster, so unless i had no other option i would prefer to leave the ports on top. outside of the intake horn, it all clears really well.

Re: 72 k20 project

I like the fabricated intakes better any way. Then you can weld in bungs for gauges, injectables, or what ever.

Re: 72 k20 project

ooo, injectables. that sounds like fun!

i made a more final HB mounting bracket. pretty slick mount, but i had to enlarge the hole in the firewall with a rotary file to get the HB nut to pass through. next will be to figure the push rod attachment, and i can cross this off the list. i may have to find an auto pedal set up too, or i might just modify this one.

Re: 72 k20 project

Please test fit your steering column firewall mount. It might have a clearance issue with your new plate... this isnt a great pic but the lower corner is notched to clear the bracket. This is my CaptainFab bracket...

Re: 72 k20 project

i kind of anticipated i would have to do something there. it clears the bolt hole, but it sill may need some clearancing to fit.i have the bod guy coming tonight to look it over, so i will probably try to test it after that

Re: 72 k20 project

What is the difference between an auto pedal and a manual?? I thought they were both the the same?? Pull the lever off the end of the clutch pedal shaft and slide it out to the left and you're done. No??

This is correct. I converted my truck to auto, just slid the clutch pedal out the side. Then I just got done converting back to manual, slide the clutch pedal back in.

Where do you work Ryan, or do you own all of the metal working tools? All your fabricated stuff looks 10x better than the factory would have done it, I love it!

I'll look into that closer. then maybe i wont have to bother Ryan. it makes sense that it would be removable. honestly i just glanced at it the other day and didnt really look it over closely at all

I sure wish i had all the tools! i get tools for home slowly as i need them, but most of my fabricated stuff is done on stuff so out of the league of garage affordability that i couldn't touch it unless i hit the lotto. i do have a welder at home, and do as much as i can in the garage. at work we have a 6x10 messer plasma table with a 2" capacity and a 6x10 Flow 3d waterjet table. i think it'll cut 8". we also have a 12' 235 ton accurpress CNC pressbrake. i am a welder by title, but i run all of them, except the Flow. haven't learned that yet. we also have big lathe and mill and i am a semi professional machinist. i.e. i am the machinist when our part time machinist is not there.

this is where i work.

Re: 72 k20 project

I am pretty sure it is welded to the shaft. i'm sure it can be all taken apart, but it would be nice not to permanently alter it in case i or someone else needs a clutch pedal sometime. if i wreck the auto to much i may end up going to a manual later.

A non 53 storm long block should be $1200 or so. These blocks seem to bring $600 by themselves as long as they don't need a bore job. A running cracked 53 block, is it 12v or 24v? If it's 24v $600. No one wants to buy used VP44's it seems, and you're in for a full on rebuild plus the price of a block. So I usually don't pay more than $600 for them.

I've also seen a lot of early 53 blocks that have never cracked. We even did a compound turbo build on a 98 12v that had 220k on it. It wasn't cracked then, makes 750hp for a year, and still isn't cracked. If a 53 block has over 200k on it, I think it'd be fine and not crack. Just info for you in case you find a good 53 block.

Re: 72 k20 project

ive heard that the early 53s were less prone to cracking. so i have a local add for a 99 cracked 53 block "running good when pulled" 24v. no pump, no manifold. the other is a 98 non 53 (which as i understand, should make it a mexican casting and therefore muy beuno) 24v, no pump no manifold. one has a flywheel housing the other does not. at least one has lines maybe both. both have heads. asking as 1350 for both. im thinking i may be able to get them for less. i am having a real hard time not going the p-pump 24v route....

am i crazy?!

Re: 72 k20 project

which also begs the question, what is my 12v running long block worth. sans pump and gear housing? and more importantly, could i even sell it. i feel like i am having my big block phase all over again, only with 6bts haha

LMAO! My brother's truck has a 00 24v with a 53 block. It had 220k? on it when he did the P-pump swap and stuck it in his truck. It has dyno'd 540hp and he sled pulled it all summer. No cracks, no electronics.

Your 12v should bring $1800-$2500 depending on how bad some one wants it. Right now I've seen guys sit on them and have to go down to $1500 to get rid of them. I'd never sell a mid miled good runner for that. Core engines with a core p-pump is $1500.
