Greg Weld's 65 Mustang fastback track car

[chetly]

If you don't have an engine guy in mind, I'd recommend Bob Wirth. He's out of Hayward California. He rebuilt the Roush Yates engine for Mike Maier after he hurt it, it built another engine for a friend of ours that's 310cid SBF and over 500hp. He's also really well known on the sprint car/ midget scene so Ron Sutton may know who he is as well.

He was first choice but can't do the motor in time. He's too busy right now. So the motor is going to Borello's

Ahh, to bad.

You mean Borrelli's in San Jose? Let me know.....I should be heading that way on Friday.

Do you find it tough to lead.... when you don't know where you're going???


LOL

You guys pulled the pan before pulling a valve cover ? Anyone cut open the oil filter ? Seems to me if you drop the float level you run the risk of leaning it out.

It shouldn't be suffering a valve train failure every other event unless Weld can't adjust valves. I could build something in my garage that would survive longer than this POS. The engine has to run how long? 60 minutes a weekend?

I agree with having it completely gone through. One lack of discipline effects the rest.

Greg, did you ever talk to Tony about adjust the valves since they are titanium and this is a mechanical?

Try to keep up --- a valve cover was the first thing pulled.

No - they're messy and our hands would get all oily. There was metal on the magnetic oil pan plug... good enough clue for me.

Never broke a rocker arm in a motor while adjusting floats before.... YOU? LOL

It won't lean out when you have 14psi of fuel pushing past the seats - lowering the floats just kept it from flooding out. When you crack the throttle WOT -- there was PLENTY of fuel. The problem was TOO MUCH fuel not too little.

In all the years I've been messing with stuff -- I've never suffered valve train issues. That would include when I campaigned a D/Gas car. Adjusting valves is a skill that school girls are taught. This isn't an adjustment issue. It's a geometry issue.

Titanium is about weight... not about how they're adjusted. They have hardened steel tips just like any other valve. In fact - that was the first issue way back - a tip "fell" off... Tony said "it happens".

I'll know what the story is in a few weeks and will post up what we find out.

[Vegas69]

A majority of the valve is titanium which means it could expand at a different rate effecting the adjustment. I doubt it's adjustment but I can tell you that there is a major difference between the lash adjustment on an all aluminum engine vs. a steel block with a mechanical, cold.
