Blown 346 cid Stroker 300

Hmm.  Think I will go check my fire extinguishers.

Always a good idea. I ordered some new nicopp fuel line, probably should have just bought some at the corner store but I'm sure it'll get used eventually. My rear section looks fairly abused but it's only about 4 ft long before it hits a union. That should make it easier to route up and over the suspension crossmember. Might need to do the same for the return which is 5/16" but probably won't need to order more. The vent line shouldn't care about added heat and the hydraulic lines may eventually go away. Current offerings for electric wing cylinders have a wart on the side and only produce 110 lbs of thrust, which I don't think is enough, but they also have a built in cut off switch which could help. I'm tempted to buy a pair of them. If I can't use them on the bonnet maybe they would work for the wing. (I'll need heavier gas struts for the trunk lid but that's coming due anyway.) Might be best to leave the hydraulic lines alone for now.

I did get the headers back in the car and the bends came for the radiator hose. Looks like a little trimming of the belt tensioner bracket and that will line up. Could maybe pull the radiator and weld in a smaller lower neck which would fit the hose better, and a bend could be an advantage, I used one on the old radiator. I could cut that off and reuse it but I hate to scrap out a part that is usable. Maybe I could get a hundred for the old one on ebay?

Now for the collectors I have this:



Instead of this:



You might think 2-1/4 is small for a collector diameter but it's the volume more than the diameter that counts and with a foot or so dumping directly into the 2" perforated tube it should be fine. Based on past performance it'll be quite a bit more than fine.

It's the details that get you on these things. With about 5 weeks left, time is growing short but I'll do what I can. I do have a backup plan at least.

I think I may have found the electric actuators i can use for the bonnet:

https://www.amazon.com/dp/B0D4LWDZBR/ref=sspa_dk_detail_1?pd_rd_i=B0CPPDLWV8&pd_rd_w=DpylU&content-id=amzn1.sym.bbb3fb5e-28ad-4062-a3ba-1f7b9f2e4371&pf_rd_p=bbb3fb5e-28ad-4062-a3ba-1f7b9f2e4371&pf_rd_r=BSN7AW7FWTCX7XE4Y3JY&pd_rd_wg=JqtFS&pd_rd_r=3e23e957-3b4c-4894-9104-933fec1ed88c&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM&th=1

About $50 ea from Amazon which is quite reasonable I feel. I just have to check the dimensions and clearances. I will have to make new mounts to the big stainless inner wing braces but I'd have to do that anyway. I think the thrust on this one is about right. If it isn't, the good news is they are available at over twice that value. I never liked the wart on the side but I've seen worse. Possibly I can locate that on the bonnet side.

I also ordered stainless bungs for the sensors:

These will go on the header pipe below the collectors. I have two O2 sensors, one AFR and one EGT. The EGT gage is for a diesel application that I installed decades ago when I was running the turbo Jetfire engine and it has a lower redline than you'd see for a gasoline engine, but installed downstream it reads lower too so that all works out. I typically see temps on that gage anywhere from 600 to a max of 1500 degrees, typically running around 900 or so. I'm waiting on the perforated tubes to arrive from the UK. DHL has them and their delivery and tracking is sorta messed up. Should be here by the middle of the week but fingers crossed on that one. They also may have delivered them to the wrong address.

I pulled the radiator back out to plumb the hoses. I'm going to add a bend to the top neck to point it at the thermostat housing which will let me get by with a simple hose with one mild bend. The lower hose is tricky of course. I clearanced the tensioner bracket to make a bit more room and plan to use a aluminum bend to come off the water pump and weld a same sized stub in the lower bung position, possibly also with a bend which hopefully will allow two short hose sections to connect up. I do like the ease with which the radiator/fan package is removed/reinstalled.

I almost forgot... The new fan shroud has to go on over the hose necks. With them both bending upwards that might work but they also both go towards the center which might not. Glad I thought of that before I started welding.

So that's finished now.



I also cut and plated a small notch in the frame rail for hose clearance and a couple other details.



And set the unit in place to sort out the radiator hoses and that's coming along.



More exhaust plumbing came in including the perforated tubes and the sensor bungs so I'll be able to move ahead with that part.



Also the linear actuators came in and they are cute little buggers. I'll be pulling the last of the hydraulics out and as soon as I've successfully tested the bonnet lift will order units for the wing cylinders also. I'll need a ground sensor and a control unit to make that work properly but I'm thinking that parking sensors might do the job.

Got the lower radiator hose/pipe combo installed yesterday finally, it was a game of many small adjustments to close clearances but now I'm happy with it. Close quarters and no photos. Also removed the bonnet actuators and associated lines as well as the Mercruiser tilt/trim hydropak from the trunk. Here are the replacements:



Open or shut will take about 1/4 of a minute but it has switch stops at each end which cures a couple issues. I'll be able to hit the switch to open and walk away for instance, and when it shuts it will resist lifting from aero effects which will be a plus.

As you can see it does not have the spherical ends so I will have to build that into the mounts. I have the bearings ordered. Once these are installed and tested I plan to order a set for the wing as well.
