72 k20 project

[ryanroo]

i may be able to wait. i have about 75% of the effort required already invested in getting my own file ready for the waterjet. wouldnt be oringed, but time will tell on how fast i get to it. so, keep me in the loop...

The same guy with the oil pan flanges has some bad azz header merge collectors too.

ill think on the pan. i am still on the fence as to weather i want a flashy pan, or an easy one.. haha


and why would i care about a thread jack at this point? this thing is all over the board already, the more the merrier!

Ryan, I saw this today at Ken's and thought about your tough pink stand. lol

[Dieselwrencher]

That looks like the engine out of Dawna's dragster. I bet flipping the engine over on that stand may require some assitance.

Ryan's has what for a gearbox? 60:1? I sure wouldn't mind seeing those CAD plans. We have all kinds of used gearboxes at work that I could adapt.
Diesel wrencher, I pm'd you a week or so ago looking for info on your vette intercooler.

[ryanroo]

I sure wouldnt mind having that engine! i do rather prefer my stand, pretty in pink, over a side mount though. I agree with Ryan too, flipping it is definately in need of a hoist. i think it probably stays upright at least dressed out like it is now. that has to be a cool shop to hang out in!

i look forward to having a nice pretty and fast engine on mine one day!

i did use a 60:1 worm drive box. as for plans... i did i rough sketch on the computer, but i kind of freestyled it as i built. the finished product doesnt match my cad file almost at all. i do need to rework the drawing for the FEA so it is accurate

[Dieselwrencher]

That definitely is a super bad CR.

Theron, I replied to your pm.

Yep, you are correct Ryan.

Yes, definitely a cool shop to hang out in but I always seem to spend money there. That engine is nice and the after market intake and exhaust are Sweet.

[classicthrasher]

Ryan, Are you not running an A/C up there in the high desert? Or are you making another cool mount for it as well? Its been a bit since I've gone through your whole build thread, but I don't remember reading anything about it, and haven't seen a compressor in any of your recent mockup?

i was eyeing the intake pretty hard. its very clean looking.

oh i have ac plans. at some point in the past i detailed the bracket i think. but here is a recent photo of the front. the compressor is high mounted on the drivers side of the engine. next to the rocker box.

[classicthrasher]

Roger that. For some dumb reason i was thinking that was your air compressor, but it's way to small for that.

I have this bad dog for an air compressor! pretty excited by this one.



so, i got the engine pulled all the way down. now i need to start the cleaning. and the spending of money... haha. for what i need to spend just on replacement seals and gaskets, head studs and whatever else pops up, i think i could have built a decent small block...



lots of parts come off this thing

I had the same thoughts after all the money I spent, but I'm glad I didn't.

[ryanroo]

yeah, i have no second thoughts. it just makes me laugh. this crap is expensive! still cheaper than buying a new truck!

its crazy what they wand for head studs, seems like there is some price gouging going on with those. it doesnt cost that much to heat treat and proof test bolts,. Due to preloading theyre still statically loaded and dont see fluctuating stresses so fatigue isnt an issue.

[ryanroo]

yeah, they arent cheap. and that is for the regular stuff. the ARP 625s i think i am going to run on my hot rod engine are way worse!

[ryanroo]

so, outside of some clean up on the block and waiting on parts i haven't been doing a lot lately. last weekend i got bored and decided to paint some of the engine bolt ons a contrast color. i grabbed this stuff. its called Black Pearl. it almost has a dark brown look to it, but i am wondering if that isn't due to the grey primer under it? either way, i still like it

here is the gear housing case and cover. cover is the GM satin black engine paint that the block/head and various other parts will be wearing.



a box of other parts.



i also did some cheesy bodywork to the cold charge air pipe and painted it.



i also took the time to clean the bejesus out of my garage. that was time well spent. so much nicer to be out there with it clean and less cluttered.

then i started looking at the front fixed cross member. im still in the end stages of head scratching. this layout might get mirrored(the bent tube in the front pointed forward) for the final version, but i havent decided what i want for sure... trying to only build this one once!

[COS399]

Looks good. I agree with only wanting to do it once, because doing it once is expensive enough.

[ryanroo]

well, i've done this whole truck at least twice i think! but i think i will get away with this one just once. the final design i decided on shouldn't be in the way of anything and i will still have space so i can mount anything that i may need to.

[1985-GMC]

Looking good! Do you have a winch going up in the front?

[ryanroo]

Not planning for one right now. i am going to try to weasel a warn vr12000 i have up behind the rear bumper for loading trailers. right now i am leaning towards an OEM front bumper and no winch. i have been idly designing a front tube bumper in my head. if i end up going that route, i will build it to hold a winch. it makes more sense to put a winch on the front of the M715 than it does this truck though.

[1985-GMC]

Oh ok, but a STOCK bumper??? That doesn't sound like you! Haha

Yes sir they are expensive. But keep in mind, there are 26 bolts that are almost twice as long as a SBC head bolt. These studs have a lot of R&D in them. When ARP first started making them they had a snapping problem. That is no fun if you just put on a $275 or more head gasket kit. And fatigue is an issue due to heat cycles and boost load from cylinder pressure. Most people using these are running in excess of 40psi boost on top of a minimum of 17.5:1 compression ratio.

[Dieselwrencher]

Nice work on the clean up Ryan. Now it's deciding just how much money you want to spend.
