Hi

On the carb model it goes to the carb auto choke.

Google photos of Beta engine and you will find some of your engine.

Hello:

Looking for the Relay IDs and the schematics of the fuse/relay box on the left inner fender next to the air horns. The main wiring diagram does not detail this area and I having some issues with I think is a bad ground.

Hi Marcus

On the subject of porting, have you ever read any books of or seen any videos by David Vizard?

If not well worth reading and viewing. One nugget was in a video where he talks about some testing of K & N filters and the conclusion he came to why they worked so well, I can dig out the link if anyone is interested (it was part of a recorded lecture in Oz if I remember correctly)

Ok, so I decided that enough was enough and the various bits and pieces for an engine build i'd collected over the years would only be any good if they were actually ever used than gathering dust and corrosion in the shed Undecided
Time frame for the build isn't much of a concern as the standard ie engine is still going well and continues to be bomb proof in the car, I could have made life easier by robbing what I need off the current engine for the new build but have decided to leave the car alone and build this completely separately, robbing some bits off a short block I bought from one of the montecarlo guys years ago which has just been sat outside since. Picture overload...
This is the chosen head of the three I came across...

I don't profess to knowing exactly what i'm doing nor recommend anything that I've done or are doing, but am purely going to do this engine build as another one of many projects that I will enjoy and experiment along the way than having any goals of achieving X amount of bhp. The goal is to of course get more bhp, but for what amount isn't something i'm affixed about; as long as it runs becomes reliable and gives the enjoyment of completing my first full engine build i'll be happy Smiley I have financial constraints to what I can personally afford to this, so in some cases parts have been sourced at cost, but to balance it off, as much of the work and build that can be realistically completed from the driveway, will be. The Haynes manual, guy crofts book and help from members will be my best friend along the way, especially Eric that has been great with info. and has already been there before with what works and doesn't, so thank you.

Having got quotes to do various bits, I thought with nothing to lose I would go about porting and polishing myself, if I was to buy anything from Guy then savings had to be made somewhere! The dremel hasn't seen much action, so about time it paid it's way. Crudely the ports were opened up to be as consistent as possible and then sanding smooth over and over...

Onto removing valves, very dry rusty valves. Having bought a spring compressor a while back, what ever was tried it didn't seem to want to know, until I remembered an old relic I had, and using the classic they don't make them like they used to they all came out reasonably easily...

These valves I bought many a year ago, thankfully in good new condition and have stayed that way. I think the plan for 2018 will be to source a VX head which Alan might be helping me out with and then utilising the bigger, I think 44mm intake and sodium cooled exhaust valves, but for now i'm going to go with what I've got which should give a fair improvement.

You have to take the back of the seat off and then you will see two clips that you have to remove  Wink

A bit of sensor info, the overheating warning light reacts at 112-118c the fan cut in temp is 90-94c cut out 85-89c assuming good sensors of course!
Thermostat starts to open at 78-82c but is not fully open until 95c.

Hi, can anyone tell me how to fully remove the front seat headrests. When pulled up to their full extent there seems to be a stop that prevents them from beng fully removed from the seat.

Yes it's always best to try to take an overview. Whichever you use is a compromise which compromise is best I'm not sure.
