Hey all
I am new to the tickford engine and am after some info for building a 4L Straight 6, Tickford engine.
I'm a mechanic and am building up a engine.
Questions I am asking are:

What engine would be best to run for performanc?

When rebuilding the engine.
Going to repalce rings,bearings,headgasket etc, is there any little tricks/secrets in building one to get a little more performance?

The engine is gonna run standard intake and exhaust manifolds.
Injectors are coming out and a carby going on,Doing this cose its for speedway and can only run carbys under the rules. Also cant run VCT either.
Looking to do a mild clean up of the head ports and manifold.
Run a aftermarket cam. Standard valves,springs etc.
Will run a aftermarket ECU for the ignition side of things

Thanks for your help and any suggestions welcome

mild port or clean up will help.why not use a distribitor out of xe carby motor no computor needed it should fit.
Make sure the timing chain is new and valve timing is spot on.

Depending on rules try and raise the compression abit by decking the block and machining the head aswell.

Thanks for the info.
Yes compression can be raised,rules say compression can be no more than 10.1, The stanadard one of these engine is 9.6 I think? What would be a safe compression ratio on one of these?

Was thinking of putting a distributor out of an xe but would it loose any performance from using ecu setup etc?

10 would be fine.as for disyy i would use just mechanical advance on it leave vacum off you should gain power you may did to get the dissy reset that is the spring tension on the advance wieghts but it should be ok as is. i would set it to the normal base timing and than advance base timing slowly makeing sure you dont get any pinging.I know standard these motors will take about an extra 5 to 10 degrees advanceno worries.

Cool, Thanks
Got a few other questions.

Would it be best to run the injected intake manifold(for better flow) and modify it for carb to fit? or run a carby intake manifold?

Also whats the best tickford model engine to start from for performance? ED, EL , AU etc?

oh and as I said befor wont be using the VCT. So doesent need that

And whats a good place to get aftermarket cam from for good price?

As for carby, I'm looking at running a holley,what CFM you recon would be the go with this?

Thanks heaps

for a manifold get on of the centre point efi manifolds of an ea falcon than it will only mean getting a base for the carby to sit on.
I would go a el tickford motor as it does not have vct so alot easyier to fit regulations.
Also get a vernier gear for the cam drive to get valve timing right.
As for cams i would talk to crow cams.
Not sure on carbyy but i would think 350 would go close.

Maxx

thanks for that,you have been very helpfull.

So you think that getting rid of the ecu,coil packs etc and run a mechanical advance distributer from a EX be better?

Thanks

goldie1

if you are running carby it is better to go mechanical

Maxx

Cool,thanks for all your help,I should hopefully be purchasing the engine this week and getting started on it.

Just out of curiosity,whats you reason behind you reconning running a mechanical with a carby is best?

Thanks

goldie1

just easier to adjust and set up.no need to tryy and reprogram the computor
