Engine Gurus...Advice Please

[Paul Schooley]

Time for a little fun with the engine. I'm seeking out some wisdom. Got a 2.7 Weber carbed engine in a 71T.
What is the recommended fuel pump (mine is spewing gas on the ground) and most importantly what's the best psi for this setup that will give decent fuel economy (best I can get and always use is Sunoco 94...cdn stuff).
I'm planning on silicone valve cover gaskets and switching from mechanical to pressure fed tensioners thus new timing chain cover gaskets as well. What's the current concensus on which gasket set is best? Silicone? Paper?
Hope to deal with this in the next couple weeks so need to begin gathering supplies to do it right. Any suggestions or advice is greatly appreciated.

My only advice is that the silicone valve cover gaskets are GARBAGE. Use the stock ones ... in my opinion they continue to work the best.

Also, if you can find a good factory carb pump then go with that. Otherwise, Facet makes a good pump, too (make sure you mount it properly).

I have both standard gaskets for the valve covers and cork ones, which
would you recommend?

Paul,
I use the stock CIS fuel pump, with the PMO setup that uses the return line and has a simple restrictor clamp to bring the fuel pressure down to the 3.5 psi that Webers like best. Check it out on the PMO website.

P.S. I've had good luck with the silicone valve cover gaskets, purchased from Pelican Parts, if I remember correctly.

Here's a pic of my setup. A bit of flash bounce, but you can see the PMO fuel block with pressure guage, filters, etc.

Cork is the devil. You'd be better off using NO gaskets than cork gaskets.

Pierburg make a low pressure rotary pump that is nice and would mount pretty easy in the 71 stock location. One other problem with the silicone gaskets is that you still have to source the nyloc nuts and crush seals every time you take them off.

That explains the half inch of sludge in the bottom of my
parts wash tub after washing the engine case.

I use an Airtex 4 psi pump at the front crossmember. Doesn't require a FPR. The FP gauge at the carbs says 3.5psi.

Nah, all that sludge is just 40 years of usage. Cork is worthless because it leaks like a seive.
