I would consider the SuperRam, a nice set of heads, and a freer breathing exhaust. For about $4k, you have picked up 100hp, and have not harmed driveability. If anything, you have improved it.

If the emission police will allow it, your better of with a miniram. A lot easier to deal with. There's an EGR kit for it now, it's not certified though.

Thanks for the informative post.
If I buy this SR, there's no doubt I'd just put it on the shelf and wait for a collection of parts to go in all at once. If someone handed me a stack of cash and told me to improve my 87, I'd want to do the intake, cam, headers for sure. I'm still uneducated on heads, and I know that's a freakin' hot button here, so I don't want to go there.
I had a feeling $1k was a decent price, but not great. Geo makes an interesting point about leaks, that would concern me. My goal is to have a moderately fast street car that's reliable. I've heard, and firmly believe the saying:

Fast, reliable, cheap - pick two.

More cam would have probably helped the Miniram, but it would have also helped the Superram. The real problem in comparing the two intakes with a hyd roller cam, is that you're limited by rpm and really no matter what you do, below 5500 rpm on a 350-383, the Superram makes considerably more torque, thus accelerates faster with street type converter/gearing packages. With a Solid Roller cam, the operating range maybe 5200-7200 rpm, it then becomes clear the Miniram is vastly superior. But, in my opinion, shifting at 6200 rpm, the Superram is a tough to beat intake if you're going to use a street friendly tight converter.

In my test, the Superram's advantage was mostly in the 60 ft time..... although it did trap speed 1/2 mph higher as well. This is because in the operating range of 4200-6200 rpm, the Superram made more average HP than the Miniram in my application. On the 60's, the converter with the Superram flashed to somewhere around 3200 rpm, whereas the Miniram, the same converter flashed a couple hundred rpm lower, keeping in mind, the torque you have below the converter flash point does matter because it does effect the amplitude of the converter stall.

On your 421 cubic inch application, the Miniram is the better choice in my opinion, simply because the Superram begins to inhibit the rpm capability with a big cube motor.... I've seen dyno's with similar set-ups to yours, but with a Superram, where the Motor made 520 HP @ 5200 rpm and 570 ftlbs @ 3800 rpm...... very stout, but the MR would be a bit more balanced and probably produce better et's.... albeit it would probably be closer than you think. With the same motor, a 560 HP @ 5800 rpm - 530 ftlbs @ 4500 rpm would be close to reality with the MR. In addition, your 421 cubic inches are providing the low to mid-range torque necessary to get your butt in motion that the smaller 350-383's just can't provide.

To add to what TPI421vette has said, I do think it bears mentioning, as others have said in this thread, you can't go wrong with either the MR or SR..... they're both good intakes and a country mile better than "any" long tube runner set-up.

Thus, if you chose an MR for your 350.... still no worries, you'll run great, and if you don't mind running a converter a little loose, everybit as good as the SR, if not better.

Good luck with whatever you decide !

I was looking at going Superram but was afraid it wouldn't work well enough at 6200 rpms on a 383 with decent cam (although I was running a 350 at the time I had future 383 plans). Also got scared away by the removal/install time and headaches. I then was looking at going Miniram but was told that they have problems with some cylinders going lean on nitrous use (still have no idea if that is true or not) and was afraid that 6200 rpms wouldn't be enough to see the true benefit of the Miniram. I then decided to go between the 2 and get a Holley Stealth Ram. I love it. Great street torque, great at the track with the rpms and cubes that suit me. I hear that USM (or something like that) is making HSR intakes to fit under the 'vette hood now. I had to go with a custom plenum. The HSR might be worth you looking into, it is easy as pie to install and it works great. I also like that you can install the base, then shine a light down the runners and see how well it matches up to the heads. Then you can slide it back and forth just a hair before tightening or you can remove it and port match it. When all is good just 4 bolts puts the plenum on.

If I wanna run a MR with my 4+3, can I expect decent results? (with appropriat parts combo, of course)

Miniram? Are you serious Bobby?

I will say, as per your below post, I personally do not recommend you choose your intake on the basis of which is harder to put on..... the difference in difficulty between the easiest and most difficult is approxmiately 1 hour of time...... I do not recommend you sacrafice 40 ftlbs of torque below 5000 rpm for 364 days of the year because on the first day you wanted to save an hour..... doesn't make sense to do that.

Good luck !

If the stealth is that much better than the MR for lower and mid-range, then it might be VERY worthwhile to give it a better look. However, unlike alot of guys, I happen to want to keep the EGR and air pump. I'm certainly not about to buy all this stuff now as we're down to 28 hours a week at work and they're asking for more lay-off volunteers. But nothing can stop me from formulating a plan for the future.(heheheh)

Aardwolf; The SR IS a great intake! I don't see many superrams coming up for sale anymore, and when I DO find them, I've been a day late or dollar short.

I really think the new Holley Stealthram might be the best overall aftermarket intake if its officially available nowadays, but not sure. I know in the SuperRod test where they took a 383, trickflow cylinder heads and a comp cams hyd roller 236/242 cam, the HSR was the clear winner in my opinion. However, it is worth noting that they used the F-body version as supplied directly from Holley. I know the brand new version that will fit under the vette hood they have to modify the plenum..... assuming that modification doesn't hurt the intake potential, its reasonable to believe this intake might be the new in-thing. I'm anxious to see how it does on a big cube inch motor.... if I don't find any results from somebody else, I'll do my own MR vs HSR A-B-A test this summer. Does anybody know how much the new corvette friendly HSR cost ?

btw, here is a summary of the SuperRod Test with these 4 aftermarket intakes:

Superram:

480 HP @ 5600 rpm
506 ftlbs @ 4200 rpm

485 ftlbs @ 3500 rpm

Holley EFI converted manifold:

493 HP @ 5900 rpm
480 ftlbs @ 4900 rpm

445 ftlbs @ 3500 rpm

Holley StealthRam:

501 HP @ 6100 rpm
493 ftlbs @ 4600 rpm

460 ftlbs @ 3500 rpm

TPIS Miniram:

505 HP @ 6100 rpm
470 ftlbs @ 5000 rpm

445 ftlsb @ 3500 rpm

The MR nipped the HSR with 4 HP peak advantage, but gave way as much as 23 ftlbs of torque everywhere else to do it. The Superram was a torque monster as you might have predicted, but gave away power above 5500 rpm to the other intakes.

I showed the torque @ 3500 rpm because its a really important rpm in my opinion.

In my opinion, the Stealthram finished 1st in this test with the Superram in 2nd and the MR & Holley EFI tying for 3rd. But, the simulator backs that up as well if these motors are in an auto, 3k converter, 3.07 gears. But, its subjective.

Just food for thought....
