Currently I have an auto iron head 86 with lt headers,and 2.5in exhaust with all the free mods and 2:59 gears. If i was to bolt-on a complete superram setup how much more hp could i expect? :smash:

 

I think you will see much more from bolting on a nice set of heads or porting & working those iron heads.

Then, after adding a good flat tappet cam and some 1.6:1 or 1.7:1 RRs to increase cam intensity, you could see some real benefit from the SR.

Also, if you do the above mods to add torque throught the RPM band adding the SR intake likely wouldn't drop low end torque below the current level.

At this point I don't think you would see more than say 20chp gain from the SR and you will lose some low end grunt.

 

how well does the 219 superram cam work with the stock TPI and ecm programing or should i wait and install the cam with the superram later?

 

I think a cam change, like any mod, would work best with all mods done. The stock TPI may be a little restrictive but should still show some gains.

If you're going to do cam, heads, intake, etc mods, you can do them in any order. The only issues are $$ and doing other things required along with each major mod, like valve springs & timing gears along with a cam change.

 

The SR will give you some HP with added RPM.

I also want to do headers, SR, and 113 D-port heads.

 

I put a SR on a stock heads/cam 89 and was very unimpressed. Once the cam and heads were done, the car woke up a lot though. I wouldn't waste my money on the SR until I was ready to do the heads/cam and SR. You could perhaps purchase a used set of D-Ports, get them worked a little, buy the 219 cam from e-bay (a new one not used) and buy the SR from cruzinperformance.com and just do the install once you have all parts. Go for a ski_down_it chip to complete.

Good luck,

Ron

 

Have to agree with 65Z01....porting the heads would give you a better HP AND torque increase than the SR at the moment....but it also does depend on the SR. Before installing the SR, go with the ported heads and some nice headers. Then put on the SR and your increase will be considerably higher no doubt than what you'd have with just the SR alone. Plus I think porting your heads would be cheaper than the SR setup for the time being.

 

I agree with everyone,you need engine mods before the SR will make sense.
Bolting it on a stock motor may not gain anything for the money spent.
Even though the stock TPI ws designed for a 305 engine,it can still feed a 350 all day long,although peaks out at a lower RPM than performance intakes do.
When you want more power,get better heads,good cam,then a SR and a good chip to make it run.

Buy some new heads and trash the Iron. That will soak up your funds.

Then save up for SR and 219, and install it all at the same time. Youll have to convert to roller at that time though, so you may want to go with a flat tappet with similar specs.

thanks for the info! :smash:

 

Let's say we dont wanna switch over to a roller setup, what kind of gains can be expected from switching over to one of those Crane compucam thingies and some 1.6rr's? maybe with a little head work on the stock iron heads

 

porting these irons is pretty much a lost cause when it comes to performance

but you can get great equal numbers from a flat tappet just like you can a roller, just with slightly different specs when comparing them

 

Is it realistically worth the effort to spend $250 for the cam, lifters, 1.6 roller tip rockers, and gaskets? Would I gain any power that i'd notice?

the cam that im looking at is:
210/216 duration @.050
.440/.454 lift with 1.5's, .469/.484 with 1.6's

yeah youll gain nice power with that cam, but youve still got the heads/intake choking it down

 

Not true. Nice gains in flow can be had with mild pocket porting of the iron heads. No they won't flow as much as the D-ports, but they are closer than you think. If you can do the porting yourself you can put your cash elsewhere.

 

Thats your OPINION. "nice gains" is a relative statement. Theres not enough material to port and porting this crap is a waste of a good Bit. D-ports are good for performance. But only fully ported will these things flow enough to match. Plus you have about 40lbs extra. Mine is that they are crap when it comes to performance.

Have you ever seen flow numbers? I doubt it. I have. Comparing flow at .500 and below (which is where most cams fall) iron heads flow within 8 CFM of the D-ports. Toss the stock valves for some Manleys with undercut stems and you can make up 2-3 CFM. If you're looking for a nice street motor and not something for all out drag racing, porting the stock iron heads is worth it when you compare dollars. And there is plenty of material to port if you have a clue what you're doing. My OPINION is based on the fact that I have ported my iron heads and have real world experience with them. My OPINION is that you need to actually turn a wrench or perform a mod before you start spreading the L98 gospel. Reading up is one thing, but nothing compares to the experience gained from actually doing something.

Yes i have seen flow numbers, and ive seen the iron heads off the car before. Those ports are miniscule. Its only worth portwork if you had to port it yourself, and youre still wasting a Bit.

You seem to think I dont do jack on my car or my friends' for some reason, I wonder what kind of moron would think so. You need to stop and think about the BS you continually spout at me before you say it. You can take that opinion and shove it.

 

:withstupid:
flyersfan1088 Vader knows what he is talking about he has helped me out on numerous occasions. You both have your own opinion as Vader stated earlier and should let the people decide on what they think is right or wrong.

 

You're right. I don't think you do jack on your car. You heard some people say that the iron heads weren't as good as the D-ports, and you're right, they're not. But somehow you twist it around so suddenly the iron heads are worthless. You are dead wrong. But you wouldn't know that because you have no practical experience. I do. You "continually spout" whatever you read on this forum. For the longest time you kept saying that TPIS sucked. Then a few threads showed up that supported them and what do you know, you suddenly changed your tune. My point is you should not spread misinformation here. There are many people that are new to the Forum looking for sound advice. To them a high post count means you're an expert while the rest of us know better. While many of the things you parrot are true, just as many are not. At least put things in context. While ported iron heads don't flow as well as ported D-ports, they outflow the hell out of the stock configuration. For people on a budget this is good to know. They see your posts and think that there is no alternative but to shell out the cash for another set of heads. It is NOT a waste of a bit as you said. But then again, you wouldn't know that.
