swapping out to a mech pump

[Mitch]

If you had not already purchased the regulator, I would have probably used a low pressure(7-9 lb) pump that required no regulator,, just to keep it simple for your mild engine. I ran a 632 cu in tunnel ram engine on the dyno with one, plenty of fuel pressure even above 6000 RPM.

Key word probably..

Key word probably..

That was my way of being kind. With a single 750 carb,, even wide open throttle he probably won't be burning 30 gallons per hour? Dyno sheet from a dual carb, tunnel ram 496 I recently ran showed 225 lbs of fuel at 5900 RPM,, 589 HP. That one had a Holley low pressure mechanical pump.

Don't get me wrong,, George at Clay Smith has a great pump,, just don't think it's necessary for his particular application.

Clay Smith is about the best mechanical out there ran one for years no problems and still have it, friend of mine ran one with a pair of Dominators with no problems...

That's what I was saying Art! I have just never been a fan of Holley fuel pumps, be it electric or mechanical. Besides, when he decides that he want to go bigger down the road, he is already set in the fuel delivery department.

You missing Mesa-co yet? Ha ha!

I hear ya, I've had decent luck with the street pumps but the electrics forget it, they're good for draining tanks though, LOL...

HA, that'll never happen, LOL....

I've known the Clay Smith family for years. They are great people. Thank you for your support.

I run a Clay Smith also and it has been good to me . I ran the edelbrock/style low pressure pumps on my hot rods and had to change them out it appears they do not like fuel with alcohol in it,the alcohol ate them up .Clay Smith does not make a low pressure deal,if they did I would run them on my hot rods best mechanical pump out there .

I ran the street pumps but not with alcohol fuels, in fact I used one to fill my surge tank for the injectors but that was with Avgas.. Would be nice if they had a low pressure deal, but I had one on my ski boat and all I did was use an injector pill holder and made a 7 1/2lb bypass worked great.
