Inlet manifold, Alternator mountings / brackets, maybe a accelerator cable and a rolling road session once they've been fitted.
Fuel pump should be OK, although we may need a malpassi fuel pressure regulator as the injection pump will almost certainly be using a pressure that'll be faaaar too high for the carbs

Don't know if they're worth it as 1) You haven't said how much they are 2) Haven't seen them so can tell what condition they are in.

*But they are worth it just for the sounds!!! Mmmmm
:twisted:

right then to start with those fuel bills tales, treated with respect they can produce an average of 30mpg no probs as this is what i achieve with mine :!: Yes they can run alot lower mpg but thats down to your right foot and self control more than anything.

I have done the original fuel pump part and found it killed my regulator after a period of time and to say its a tad to much for carbs is an understatement lol, far easier to get a facet red top fuel pump and regulate it down by a few psi instead of loads. I use a filter king which acts as a glass bowl inline filter with a regulator built in on top of it. normally around the ?30 mark i think

polished,ported,gas flowed and skimmed head
4 branch manifold
full powerflow system
piper 272 cam
k&n 57i

Those are the mods u have listed in the past, twin forties will show a good improvement on what you have with the injection system at the moment. BUT..... after removing the injection system it will pay to either get a 1.4sr dizzy and coil for the ignition side of things or look into forking out for mapped ignition using dta or something like that as i learnt the hard way with this lesson. i took the 1.4sr route as was alot easier and cheaper

200 quid for the lot including throttle linkage and brackets, look in good nick just need a good clean up.

would my cam be ok with this setup?

so i just unbolt the inlet, take off the ECU and injection wiring and bolt it back on (carbs) and get a 1.4SR dizzy and coil??

get a fuel pump wot dan said aswell

heard u can get around 20BHP from this, this true??

could this be done in a day? is it easy 2 setup ur self till i can get it 2 a rolling road?

thanks alot
