Both holes are now cut and opened out correctly in the body. The collectors have been on and off half a dozen times or so trying to get the clearance neat and equal all round, but the holes now seem to be correct.
There have been issues on both sides trying to get the collectors far enough onto the headers to allow them to run parallel to the car. After tightening up the header bolts, and pushing, shoving, swearing and employing the carpet and hammer trick I still couldn’t get them closer than comming out to corner just over 2 and a half inches from the body whereas I needed that gap to be about an inch. Looking for alternative suggestions I found a forum post that recommended just chopping a little off each header pipe’s end from the man that made them so after doing just that, they’ve gone on and now fit perfectly.
They need to have a self tapper put in place on each side, from the headers to the collectors to stop them dropping during use and I need to pick up a couple of powder coated brackets from Dax to allow me to tie the back of the exhaust to the chassis using two large rubber bobbins as vibration dampers.
Now onto the pipework for the engine and getting the thermostat in place and water-cooling all linked up…
The pedal box and brake servo have finally been fixed properly in place which involved being upside down for a good hour or so, dropping more nuts than I care to say and with my head stuck in fibreglass dust which is super itchy! After lots of taping for the head of the bolts on the engine bay side to try hold them in place (it really would be easier as a two-man job), trying to thread the nuts on upside down in the foot well with a sprinkling of cursing to help get things into place the job was done. All frustrating stuff but equally rewarding knowing that another bit is done.
The next jump forward was the final fitting of the gearbox to the engine. This had stood beside the car for sometime “looking” ready but there were two holes that needed bolts in place to get he bottom of the gravel shield fixed to the box. The engine has a “special” oil sump which mean that there was no space to use the standard cap bolts so it had sat like this for a few months (12?) before I managed to cut some studs and set them in place using some good strength Loctite. Another job needing expert skills in wriggling your fingers in small spaces to slip a nut into place as the box and the engine were mated whilst balancing the gravel shield in the right position.
With the gearbox mated properly to the engine, the side vent studs were glass’d in to the body to create a stronger bond for fitting of the side vents than the worth adhesive that I had used a few months earlier but had proven to be a little badly done, or just weak.
With much if the engine bay work completed and a new birthday present of a hoist level I trial lifted the engine on the scaffolding gantry (built about a year and a bit ago!) That seemed all fairly simple and as it was working as planned I decided to have a go at getting the block in to place. Surprisingly enough one of those jobs that I’d worried about my ability to do was fairly painless and after a couple of hours, or even possibly less, it was in! The gantry rolled well over the engine bay allowing the block to be manoeuvred a few mm at a time and lowered as needed. Jacking the back of the car up made a massive difference and allowed the gear box to float in through the bulkhead opening without any drama. A couple of bolts later it was all tied in place via the mountings and the gearbox mounted using the support plate. A massive feeling of progress, and a big empty space where the block used to sit!
The only thing I’ve gone backwards on a little is the timing needs to be redone for the engine – during the lift it became apparent that the distributor was going to get in the way of the lifting chains but being slightly over zealous I remove what I thought was the bolt attaching it to the engine, only to finally understand how those things worked – there was a driven column that went into the engine which tee’d which spark plug was firing depending on the rotation of the arm within the distributor. It was all mounted back in place pretty carefully to avoid any rotation but I suspect it should be double-checked to avoid any problems. If I’d only googled it first I could have saved myself this added job as removing the top cap was all that was needed. I’ll add this to the things to be read up on before possibly asking a professional to do it!
Build Time: Possibly 195 hours or so?
I feel like I’ve started making some achievements. After fiddling around with the radiator and trying to get it to fit in the “standard” manner I’ve given up and position it on a slight lean so it fits nicely under the front body work and just above the lower air scoop of the body. Positioning it vertically resulted in it hitting the body work which Andy at Dax told me to leave a 10mm gap on. Sticking on a slight angle sorts this nicely. I do have two holes that need to be blanked off though that I originally drilled for the “correct” positioning of the lower bracket!
It’s a heavy lump of metal that starts to make the nose of the Cobra look how it should!
Next, after getting to grips with scaffolding and scaffolding castors I’ve ran a small test of my make shift gantry and lifted the second large lump of metal into place – mating the gearbox with the engine. It’s all been relatively straight forward. It’s not tightened up yet but all resting on some lumps of wood (not those under the sump) and the original engine frame. Next time I’m down the garage I’ll get everything tightened up properly and see if the gantry will take the weight of the engine and the gearbox… … …eek!
Build time: 174 hours
A rather large truck containing an electric pallet trolley, one enging and gearbox from Jez @ CPP turned up today. After unwrapping plenty cling film it looks great and very shiny!
Whilst I waited for the delivery I fitted a few more rivets and gave the garage a long overdue tidy and clean.
Build time 103 hours
Jez has been busy again and the engine should be ready for delivery next week! How exciting but also how scary as I’ve got to fit it! This seems like my first “real” job that’s now becoming a reality! 😀
There’s been no progress on the car for the last few weeks as I’ve been in the midst of moving house but Jez from Custom Power and Paint has started building my 383 Stroker..
The next big ticket item is now on order. After a few hours on the phone over the last few weeks with Jez at Custom Power and Paint I’ve confirmed the order for the engine.
The original plan was for a small block 5.7L Chevy 350 with about 350bhp but the order’s gone in for a 6.3L 383 Stroker 😀 It should put out between 400 – 420 bhp but also be very “well mannered” as it were…
8 to 12 weeks lead on it so all the more to add to the excitement levels, plus the wheels are due in tomorrow…
