Question from NEWBIE regarding fuel for 1967 fastback

[argoose]

Dear Mustang PHers

Quick question regarding fuel for a 1967 350 mustang??

Do you need to use a fuel additive to help the engine or is it not an issue

[ZR1cliff]

I haven't driven mine yet because it was siezed when I got it, however when I had all the engineering done on the engine, unleaded valve seats were put in. I've heard some owners use an additive, but not sure what one.

Cliff Previous owner had the engine rebuilt but because it was done in the states not sure if they did valve sets.

Are you having any issues with the engine at all, Angus?

Hi Cliff

Sadly can't drive any cars yet due to a recovery from Brain Tumour operation and hospital will not let me drive. So I just looking at it in the garage

Hoping that by Feb 2013 I will be back on the road. However Mustangs going to a friends place to set up the jets and sort timing and remove the racing clutch so its ready for Feb;)

Can't wait to see your beast on the road!

Sorry to hear that, Angus. Here's to good health and having you back on the road soon!

'Racing clutch' why are you taking it out, is it too noisey?

I would imagine that if the engine was rebuilt, it would have hardened (unleaded) valve seats. Given the US was using unleaded well before us, I would think any rebuilds (unless going for concours correct) would be done to be ready to take unleaded.

If you're unsure, some fuel additive might be worthwhile to be safe though.

Good luck with your recovery

Hi Cliff, Well mate the Clutch is just to hard for me to handle its very harsh and my clutch leg is on the side of my stroke. Bizzarly my other car a 6.3 Chevy TVR Griffith which has a racing clutch which isnt a problem however the Mustang clutch is so very harsh. Its been suggested that I could go for a road racing clutch?

Thanks Paul
Hoping to speak to original owner in the states at some point and hope he will confirm that when engine was rebuilt it had harded valves.

I've got a lightweight clutch and flywheel in my ZR-1 and find it very noisey. Sometimes wonder if it's worth it considering my car spends most of its driving time cruising these days.

To be honest a noisey clutch isnt what I want in the Mustang because it will be doing a lot of road trips next year. However my Griffith is for short blasts and is running an LS1 power plant which has a 382 stroker kit fitted the road racing clutch which is very quiet. But at just over 1000kg in weight so its not very heavy and pumps out of 400bhp at the wheel which is stonking. However I do love the ZR-1 its a stunning car but wife would walk if I had another toy very nice mate.
