Projects How good is the P.E.S ram intake from 12-bolt for my 292 Chevy?

I know that the intake is not heated blah blah blah, but I have my own solutions for that issue! I am just really wondering how good is the thing on overall power compared to an offenhauser intake for my 292 Chevy

 

That one is a "race only" top end manifold.

 

Personally, I like the Clifford intake over the Offenhauser for the late model, Chevrolet sixes (194, 215, 230, 250, 292 sixes). There is "another" six cylinder, roundy-round application intake that's a race only piece, although I have seen one on a street driven car (forget who makes it, but it's probably the P.E.S. unit). Irregardless of the intake used, the intake ports on the head really needs to be "lump ported" to open them up, and basically match the intake runners. I am Butch/56sedandelivery.

 

all I know for sure is the Rifleman is a bad ass, he can shoot 13 rounds from a rifle that holds only 8 and he does it 12 years before the rifle (1892 Winchester) was even made since the show took place in 1880. best western ever.

I'll be watching him later today at 5:00

 

I'm definitely going to do a head upgrade with the heads from Tom Langdon over at 12 bolt. They have the lumps, valves, etc etc so I'm just kinda determining what kinda hardware I want to match those awesome heads

 

I know right! I'm a young kids Saltillo but I really can appreciate those good Ole shows like the Rifleman. I watch it with my dad every Saturday night (tonight ) because we record he them throughout the week!!!

 

Foes the clifford mate up to the original exhaust manifold so I can use that heat riser for cold weather?

 

I'd really go with headers to free up some HP; they are make cast iron headers for these sixes now also, and I believe they have provision for heating the intake similar to how the old Fentons did it. That is unless you plan on turbocharging at some point, and using the stock exhaust manifold for that purpose. I am Butch/56sedandelivery.

 

You know Jesse your slight obsession with cold weather and heated intakes may need a wee rethink if you could force yourself to do that. You said cold Texas weather? Son , let me tell you about cold. Up here in the Great White North we don't worry about heated intakes on hotrods. We just give them a few minutes to warm up. In fact of the hundreds of engines that left this shop over years (including sixes) everything Hi perf had the intake heat blocked. I do not find that a problem. With in five minutes it is fine. Sixes or V8s. A heated intake is hard on HP as well. On a 440 build Bill Bagshaw found a gain of 28 HP just by blocking the heat riser passage in the intake manifold. Its your dime for sure and I respect that but??
