Hey guys I've been reading for hours about cams and I can't seem to find anything that pertains to my setup. I have a 1990 base model auto. Tpis long tube headers, true dual exhaust with h pipe cats deleted edelbrock 29785 intake manifold super ram intake also edelbrock 6087 performer heads. 24# injectors. I have two questions what kind of horsepower do you think this setup will run and what cam options do you guys recommend???
Tuning will have a huge impact on horsepower. Guess is your probably around 285-290 hp.
Stock automatic has either 2.59 or 3.07 axle ratio. If you have the 2.59,IMO gear change to 3.07-3.73 is required before cam change. Used D36 3.07 assemblies are thrifty and easy swap. Cam selection will depend on how you will use car, highway, stoplight grand prix, auto X. New cam will also require new tune.
I can't find flow numbers for those heads. Do you have any? Also, are you saying you can choose between the two intakes: Super Ram or Edelbrock 29785? Because which of those you use will make a big difference in the cams you should look at.
The 29785 is a carb intake manifold as far as i know, its not meant to mate to Superram. There is an Edelbrock base that can though.
That question must be cleared up before a cam choice is made, the cam must make power where the intake can feed it.
I bought the setup off a guy who ran the super ram on the edelbrock carb single plane intake why would this not work ? If he had it on his c3 running it has to mate no ?
I would look at what 24# injectors can support then subtract 15% for drivetrain losses to get a ballpark ideal of the max possible power first
90% duty on 24# is around 340bhp so 340*.85 = 290rwhp possible
So, something less than 290 horsepower to the tires
Cam recommendation: I recommend you leave the engine alone. Focus on maintenance, cleanliness. Measure the crankcase pressure and upgrade the pcv system and pcv valve (new hoses, correct filter, use a pcv valve from a 98 Toyota Supra IMO in line with the OEM pcv valve)

I believe they're regular performer heads. They should flow around 230/175 at peak. Nothing special.

The super ram is exactly what I have i know what it is so your saying thr super ram will not work with that intake manifold ???
An Accel Super Ram is an intake manifold, and includes the plenum, runners, and base. The Victor E you say you have is also an intake manifold that includes the plenum, runners, and base (all cast as one piece). If "you know what it is" then you know that this:
Doesn't "work with" this:
They are two items that do the same thing and don't work together. You use one or the other, not both. You don't "run a super ram on the edelbrock carb single plane intake" - that's not how any of this works. Is this a real question or are we being trolled?
If it's a real question, then you should use the Super Ram with those heads, because those heads don't flow much and won't support the Victor's strength (lots of flow, high RPM, high power). Then use a small cam kit such as the Comp Cams K54-408-11 kit, and you might get 300rwhp out of it. It would be a real upgrade over the stock L98 at that point. You might need bigger injectors - I'm not sure - and you'll have to figure out tuning because this is enough change to require that.
Maybe you have a complete super ram AND the 29785 intake. That intake number shows up as a super victor with a 4500-8500+ power range. To fit the super ram to the intake someone would have to block off the runner ports then cut an opening in the bottom of it to match the intakes opening. Could it be done, maybe but theirs lots better options.
Ok so it seems I bought a setup that included a base that is basically useless to me ffs I figured it would work as he was selling it as a combo. So my super ram did not come with a manifold what manifold would you suggest with my heads ?? I'm so ******* pissed off right now
Open the manifold box to make sure its really a victor intake. Maybe youll get lucky and he put the accel manifold in there.
id love to but I'm out of town working for the next month. I will get my wife to do it tomorrow and send me a picture i hope to God its the right base. So if its not anyone know what I need to purchase??
Well my wife absolutely hates me right now for waking her up hahahaha but yeah the guy that sold it to me put it in a different box it is the correct manifold thank **** and here i was telling my co worker I was going to drive to this guys house and boot stomp him
Cam suggestions
what manifold would you suggest with my heads ?? I'm so ******* pissed off right now
