any opinions on the aluminum warrior intake and how it may compare?

helicoils, sure.
but if the intake isnt better than the iron one, than its something else to eventually fix. ( i mean no disrespect tho!)
i bought an iron for my car and will soon be recycling my performer. (its not an RPM).

does the RPM have any advantage on the low end torque, compared to the iron? or does the engine lose any torque by useing the RPM instead of the factory iron?

this car will mainly be a cruiser/ tire smoker, we dont wanna lose torque heh heh...

i'm just trying to save him a few bucks as we need TONS of stuff to get this thing going.
there's a tight budget, and we still need a dist, cluch, pressure plate, flywheel, ect ect ect....

My bet would be the bigger runners of the RPM would loose a little to the iron or HO intake. Both can perform good up to a fair amount of HP so save the money for another part.

I think if money is tight, like most of us are now, I'd go with the iron, or an HO if you had it.

FWIW I've have lots of aluminum intakes on lots of different motors, if you are careful you can keep the threads OK with alot of use. Now early 60s GM alumium intakes used a really soft aluminum that was even more prone to that, but even my aluminum 409 intakes have all good threads.

If the 455 is different. What would be better intake to use on a 455. One from 1969 or one from 1975?

The earlier one. The 75 is heavier, uglier and has the EGR tumor growing out the side of it's neck.

yes. i think it still performs tho, right?
i wonder how it compares to the earlier intake? i see those egr intakes for 20 bucks on craigslist often.

[Overkillphil]

Close yes, but just because Rosanne Barr can cook almost as good as Cameron Diaz...well you know.

Got the 69 on now, curious how everyone thought of the 75. Looking fot a HO one for the car

[disc0monkey]

i had a very similar combo to yours...13 heads but i had 3.90s, headers, and TH400.

I tried the '71 stock iron intake and it lost something like over 3 tenths at the track compared to the rpm. nothing else was changed not even the jets in the carb. i have some more posts on this topic but it needs to be searched.

X2

I just went from an unmodified T2(+1" spacer) to head gasket matched RPM (no spacer-clearance issues)and lost approx. 5mph. No other changes were performed and the idle, cruise and wot afr was identical on both intakes.

Boy, would like to hear you swap on a hogged Torker I and show gain ((((based on improved flow trajectory past the pushrod bulges, to prevent turbulent flow)))) over Torker I I & RPM.

Alleged, supposed, and suspicious that Manifold-Head combos are hit-or-miss depending on the pushrod bulge & effect on Head's intake runner turbulence situation.
