Nice, did you change intakes again? Thats a Mini Ram in that pic.

A 377 huh? That would make a nice reving motor. I have a 2 bolt 400 block in real nice shape that I am thinking about throwing in mine. I have been looking at rotating assemblies for it. I would like to make a nice solid 500 NA crank hp. Patriot has a nice set of heads that I am looking at as well.

I plan on running a pretty hefty hydraulic roller 292/300 duration .584/.579 lift.

Different motor, for my buddies 92 GTA.

This is a 377 too, med. race port heads, mech roller.... and all. Should spin to 8K easily.

Well, tore the motor apart and decided I needed to take one of my old oil pans and fabricate a drain tube w/ NPT thread so I can use AN hardware. I hate hose clamps.



I have an hoses on most everything, same for the supercharger. I'm going to undo the FMu of all that ugly black quick disconnect fuel hose too





I figured this was the best way to do it, most room for draining right there and angled up and toward the supercharger so there's no horizontal spots in the drain line )especially since it's a rather small ID line, I use -12 stuff on my turbo motor)

I also had to hammer form and reshape the whole deeper sump section because as I suspected it didn't fit with the milodon oil pump and pickup (not a fan of the melling pumps)
All I have to do is blast and powdercoat it now. It's getting there now. Different color, it was supposed to be red. As soon as it hit the engine (primered silver even w/ aluminum epoxy paint) it turned to a shade that's a lot more orange than red... damn! A redder shade of chevy orange. I didn't want it orange but oh well.

Oh wow, you got some serious ATD man!!! I like how the project is coming along. Do you have a planned time frame as to when the car will be ready?

Twin_Turbo

iTrader: (25)

It's hard to make a time frame, one has to plan everything ahead, if I miss a part, have something that doesn't fit or change my mind I have to order in the US most likely and it takes weeks to get here. That really does not help a lot....and I have this nasty case of "whileI'matit-itis" and things always get out of hand. I had hoped to have it finished this year as far as putting the engine back in again and having a running car.....looks like it won't pan out that way.

Who's heads are those? I've never seen canted valve smallblock heads!

Edit, I see they are trick flows, I didn't know anything like that even existed!

Twin_Turbo

iTrader: (25)

They don't anymore, those are G1 heads (have 2 sets of them now), the G2s have angled intakes and exhausts, these just have angled intakes. They are not canted.

I agree, after seeing this, i cant wait for winter to be over so i can get to work on mine!!

Twin_Turbo

iTrader: (25)

Meh, didn't get a lot done. Waiting on the zz409 cam so I can't button up the engine and drop it in

I did install the booster pump. Apparently the procharger instructions tell you to screw the pump to the floor pan and to cut a fuel line and use the supplied rubber hose to plumb it in. That stuff doesn't fly for me, so I came up with this. Some adapters on the short rubber section between tank and body and using AN hardware I routed it to the pump. unfortunately the pump has hose barbs so I had to resort to hose clamps there (I hate those things) but all in all it's a lot cleaner than per the instructions. That Fays 2 sure is handy for hanging stuff off. Still have to zip tie the lines and electrical wiring to the fays2 crossmember

Where did you get that boat intake from? I have a friend who has two of them but won't sell.

Twin_Turbo

iTrader: (25)

What boat intake? The one on that engine? I got it from someone on here, it's a prototype sand cast unit as far as I know. It's not a production casting or a very low volume casting series.

I know Mercruiser had this intake but it's a BBC one. You know what I have here?



What does your friend have? Can you arrange a pic?

Jeffs82TA

iTrader: (1)

I can try to get one. No his looks more like the one on the engine.

I've been meaning to find out what it is, please ask the guy and maybe get a pic.

Humm....one side has rust behind the ground effects. No wonder, screws thread into bare steel. Probably self tappers too. More stuff to fix



Took the whole wing off because that side needs the door hinge bushed too



Thinking about going with the later GFX, the fake air ducts give it a more modern look

96LT4c4

It looks like you have some of the same rust issues I do. You may want to go ahead and pull the GFX off the rockers. Look at the rocker right in front of the rear wheel. I did some searching and figured out that the water gets in from the LCA bracket on the body. If you unbolt the LCA from the body you can stick your hand in the hole and feel where the water gets in. I made a sheet metal block off plate and tack welded them in the holes, then I will just seam seal around them.

Twin_Turbo

iTrader: (25)

I have all the GFX off and this is the only rust spot

The area where the rear of the rocker is bolted in from inside the car near the seatbelt retractor is also an area where water collects if the rear inside fender is rusted out, water will run along the edge of the fender lip and end up in the deepest spot being right behind the door

I'm gonna hit every nook and cranny of the rockers and other closed spaces with wax, no more rust for me

96LT4c4

I had a pretty good size hole on the drivers side. I cut the rocker open and rebuilt it from the inside out. I didnt notice the pass side until I striped the paint off and sprayed epoxy. I started to wonder that if there was rust on the drivers side there had to be some on the pass side. So I went back and took a closer look. Sure enough there was a tiny pin hole just big ehough for a pic. After cutting it out it was actually worse on the inside then the drivers side.

I bought a 3M schultz gun and wand. I planed on spraying Chassis Saver in there but I am threw with that stuff after having some flaking/peeling issues with it. I will buy the 3m body schultz/wax to spray in there.

This is a cool thread all have to take some time to read it, anyways looks great! Thats cool i didnt even know they made "from what i can tell a bolt in parallel linkage setup"

Twin_Turbo

iTrader: (25)

Took some tweaking to get the mount installed. Since I designed it with the dims off the summit site the top was too wide to fit the core with the rad sitting as offset as it does because of the non direct fit. A little cutting and filing here and there and it's in (it's on the GTA but the same as on the 87).





Didn't get to do a lot more, stripped most of the front end for spraying and fixing some minor issues.

great thread, keep it coming, i love stuff like this

Going to install 2 Spal 12" high perf. puller fans instead of the stock dual fans, problem is I'll have to design a mounting bracket or shroud for them. More custom work to be donie.



Ignore the crookedness of the radiator, that's how we receive our stuff here courtesy of UPS.

Quickly designed a neat mounting bracket. Didn't want to go with a full shroud, the fans will cool plenty as is and I don't want them to mount closer to the engine and with the fans against the core a shroud is useless. It's the yellow part in this design

If you don't mind me asking, how much has the cost of this build totaled? I've been thinking of doing this to my car for a while.

Twin_Turbo

iTrader: (25)

Good question, I usually don't add up prices (denial) but it was quite a bit. It was over 10K in Euros for sure but the prices here (once stuff actually gets here w/ taxes and all) is about 1.7-2.0 times the list price in the Summit catalog or wherever. This is the price thus far, and possibly it was even more since I only added the large bits and pieces and not all the small stuff. It gets very costly very quickly here.

The larger bits include:
wheels, supercharger setup (still not 100% complete), new heads, intake, injectors & fuel line stuff (fmu, pumps blablalba), baer brakes, rear pbr brakes, sandblasting and powdercoating, a whole bunch of rebuild parts like complete new susp & steering setup, ball joints and bushings, yellow konis, j&m strut towers, edelbrock stb, summit radiator and a whole bunch of other summit parts, Fays 2 watts linkage, TA rear end girdle, 2 spal 12" fans. I didn't even include all the interior pieces that I bought for it (apart from dash almost everything)

Still leaves the paint job that has to go on it, the stainless exhaust that I have to weld up (I have the mufflers, not included in total). Imagine farming it all out here, it's going to put one in the poor house for sure.

1st of all DAMN!! What a build!! Great thread!!
2nd, If I may ask about the TFS heads. I have a set of these I aquired for my 383 build and between looking at TFS instructions and listening to what old school people around me are saying. I'm concerned about push rod length. The manual gives you a part# for push rods that are equal length. Some old schoolers around me say that is hog wash and the intake push rods have to be a different length than the exhaust.... Any advice???

Looking foward to the rest of your rebuild!!!

Twin_Turbo

iTrader: (25)

Yes, the exhaust on the G1s is at a std. angle, the intake not. Use and adjustable length pushrod to find the best geometry where the rocker tip sweeps the center of the stem, not the outsides. That's the only proper way to do it.

Any updates?

Twin_Turbo

iTrader: (25)

No, I was waiting on my cam from TPIS to show up all this time, the mailman tried to deliver it today after the customs ***** held it hostage for 3 weeks trying to figure out how much to rip me off for this time (the mailman had a nice bill with it for over 140$ in taxes and duties and since we don't have checks here one has to pay in cash, didn't have that in small change on me so it'll be here tomorrow) So, I can put the engine back together, bolt up the tranny and drop it in. Got my fat mat stuff in too so I can apply that on the inside. After the engine/tranny are in and the torque arm is hooked up I will start work on the SFCs and exhaust and also on the intercoolers and ducting. Leaning towards an air to water intercooler so I can stuff it where I have some room.
Fan bracket is ready too, can weld that on this weekend and mount the radiator after dropping the engine in and wire it up. Things should pick up speed from now on.

Jeffs82TA

iTrader: (1)

why don't you just weld some aluminum tabs on the radiator tanks and run LT1 dual fan shroud?

Twin_Turbo

iTrader: (25)

Because the spal fans flow a ton more air than the stock things and I don't like welding just a couple of tabs on there. It has to look good & be functional. I'm a sucker for neatness and generally don't like OEM solutions like the stock dual fans. The fan blades are wobbly, they are not perfectly flat and as a result vibrate and are noisy.

I've done the tab welding deal befre:









I like the way I designed it this time better.

Rich2279

iTrader: (7)

Ok, I'm interested.

Twin_Turbo

iTrader: (25)

Here's ver 2.0 of the rad mount, this time I can dimple die it. This version fits around the tanks, not just the core.



The fan shroud


Started putting the engine back together after finally getting the zz409 cam (stupid customs here was holding on to it for a couple of weeks). Also visible is my drain hookup for the P600B.



The stock v/flat belt combo pulleys are giving me issues, I'll either have to convert the aluminum spacer thing for the SC pulley into a pulley by having it cut or flat belt grooves or have a new one made with a wider front diameter for a larger pulley. I already have a smaller waterpump & alternator pulley.

Twin_Turbo

iTrader: (25)

Got the radiator all done:

Fits like a glove


Used carriage bolts, the square below the head is hammered tight into the aluminum so they won't spin


all done, these fans move a lot of air. Gale force winds LOL



Rad mount ver 2.0 now dimple died


The whole shebang installed




I also made good progress building up the engine. Cam installed and everything buttoned up/dialed in. Mounted the supercharger and made a custom little bracket since I don't have the OEM serpentine drive, it spaces the whole assembly forward about as much as the stock serpentine stuff does. Also, there's an additional hole that corresponds with where normally the bolt goes through the alternator. I'm going to add a 4th bolt & spacer to it since I still have 1 unused hole in the head and bracket. There's a small bolt in there now, adding a longer bolt & spacer only required drilling the supercharger bracket. No big deal. Also have the oiling system & return all hooked up. Going to either cut serpentine grooves in the drive spacer (alu spacer thing) or design a new one, larger diameter. Have to figure out the drive ratios first and see where my KRC pump ends up.

That engine looks like its gonna seriously kick. Do you have any estimates as to what it'll be putting out? And forgive me if you already mentioned this, but are those 3 fuel injectors on the plenum above the throttle body?

89ROC-Z

iTrader: (7)

just courious...is three bolts all it takes to keep the charger bracket from deflecting?

Twin_Turbo

iTrader: (25)

The 3 injectors are part of a super fueler setup.

Originally only the 2 left bolts hold it to the block, the 3rd one where I have the same long spacer as the other ones originally bolts to the alternator, through the original serpentine setup brackets and some setups have a little additional bracket that bolts to the back of the alternator where the support rod also bolts to it and then to the supercharger bracket.

Once I replace the small bolt on my head bracket with a long bolt and a spacer (and drill an additional hole in the SC bracket) I'll have 4 bolts/spacers holding it up. That should be plenty sturdy but I intentionally left the head mount bracket oversize so that I could add another hole for a support rod on the side.

This is with the stock serpentine setup not a lot to it either:

Rich2279

iTrader: (7)

I've attached your pic. of the fuel lines and I've numbered 2 of the lines. Is the fuel line that is marked #2 the fuel return line? #3 would be the evap line?

Twin_Turbo

iTrader: (25)

3 = return, 2 = evap

Did some more work. Started doing the inside with sound deadener



Found a clean way to mount the FPR, only need a 90deg. 3/8 -> 6 AN adapter to clear the valve cover. Also visible is the sandwich plate w/ 3 injectors, part of the superfueler.





Installed a 92 KC4 heat exchanger because of the way it bolts up without using hoses & hose clamps and the lines are aluminum (now powdercoated) It's a real tight fit with the headers. Good thing I have wrap around them.





Added the 4th bolt to the SC bracket

Rich2279

iTrader: (7)

Darn, I guessed the return line was next to the pressure line (#2). Looks like I'll have to change them around.

Thanks
