Which Intake to Use?

Post by colnago »

Long story short, I rebuilt my 352 this last summer, but used a 4BBL "T" intake manifold instead of my pre-build "S" intake manifold. The "T" has a '75 date (D5TE), while the "S" is from '68 (C8AE). Now, I'm wondering if I made the right choice. Does anyone have any stats for these two intakes? Flow numbers, port sizes, anything? I'm using C8AE heads, so one would "assume" that the "S" intake would be the one to use, but I've always heard, "T is for truck, and S is for suck." Are they pretty much the same? I'd hate to swap for nothing, but I'd also hate to not swap if the older manifold is better. After all, '68 was pre-emission ...

Thoughts?

Between those two? You'd never notice any difference. At the RPM range you're running the'll both be virtually identical. Furthermore, in your truck, you'd see little benefit with anything new and fancy.. You're just not making enough power, or pumping enough air, for it to matter.

I'd say stick with what you have, and focus really getting detailed with the tuning. That's where you'll find advantage.

I don't think I'd see any benefit from it. I suppose if I found one for cheap, I'd try it, but I don't "light up the tires." After all, this is a truck. It's my daily driver and dump-runner. It rarely revs up above 3,000RPM. I'll probably stay with the "T" manifold, but I had to ask.

Well, I think I convinced myself to re-use the "S" intake. I can take my time cleaning it up, then spend some extra time to clean up the internals (smoothe out the channels, match the ports, etc). Best of both worlds, maybe. Good thing I have a hoist, because we all know that these iron intakes are @#$%&* heavy! And as far as I can tell, the weight is the only benefit that the Performer intake provides (I understand the Performer RPM has major benefits, but I'm a low-RPM kind of driver).

Besides, this satisfies the "tweaker" in me (for now).
