Need some advice on what Heads/cams set up to put on a 396.
Hey guys ive been researching other people's posts and i just cant get the exact answers i need, i would like to know what kind of set up i should use for optimum performance in my car, but it will also be a dialy driver, atleast for a while, anyways its a 350 bored to a 396, and im leaning tord AFR heads would this be a good idea?, and also what kind of cams would be best with this combo?
any help would be greatly apreciated, thanks guys!

Well you cant treally pick a cam without first settling on an intake. The cam is going to need to flow best in the RPM range in which the intake is designed to make max power. After an intake and cam are selected choosing the heads becomes pretty easy.

Go with a TPIS mini-ramIII, Ported vortec / or fastburn heads, and a Comp Cams XR276HR-12
It's a damn good streetable combo that would run 12's no problem, maybe even a high 11 !!

careful machine work and assembly using a Cola forged 3.875-inch crank and Lunati internals (Pro Mod forged rods, custom 4032 alloy pistons, chromoly rings, bearings, wrist pins and locks).
I see 400+ Ci small blocks all the time

You said " 350 bored to 396" Not stroked. I was just wanted to stay on top of any new stuff that might be on the market.
I have lots of 400 plus small blocks. Here is a picture of the all aluminum 400 plus SBC that I am building for my 92 camaro.

I have started to get the parts for a long stroke 350 block motor for my kids car. I have a cola 3.875 crank and some 6 inch eagle h-beam rods for the 350 block that will come out of my car when the aluminum motor is installed. The other way I can go is a World Motown block and than it will be a 429 but I think one car with an aftermarket block enough. Do you drive your car on the street. Do you have to smog it.

Confused...
well i found this article written here on the boards and i got this info about the Mini-Ram intake-
"The TPIS miniram was the model that GM used in designing the LT1 intake(they look similar?),and makes max top end hp with the expense of low end torque.The miniram has very short runners(about 5"!) and a small displacement plenum,couple those two items together and it pulls to 7000+rpm.To show you how much it kills the bottom end,driving a LT1 is like driving a 4 cylinder turbo compared to an L98."
i dont like the sound of that....
so now i dont know what intake to go with...

If someone could plz clear this up that would be greatly apreciated, what i want is a dialy driver that can do 11's and i live in cali so the emissions are strict but im not really worried about that cuz i know people that can pass me, but i dont want any elligal parts either.

I think with a 396 you will have more than enough torque with any manifold you choose. Correct me if I am wrong, but I don't think the miniram is emissions legal. For an emissions legal intake I would recommend the Super ram with some porting. It's kind in between the miniram style intakes and the LTR intakes.

There are probably over 1000 threads regarding the MINRAM Vs. SUPERRAM Vs. STEALTHRAM and how they all operate differently in the RPMs. You will need to read and read and do some soul searching before you decide on what will be best for you and your skill level of building a total performance package. It probably wont be best to take a few opinions on one day and then go buy a bunch of parts the next.

If your looking for "smog legal" than the only intakes are a LTR TPI or a super ram on a TPI base.
The Mini ram, converted LT1 and the Holly ram all have no EGR and thats one of the first things the Smog police look for.
Jerry
P.S. I found a scrap prototype LT1 intake with a third gen EGR on it. The intake convershion is not finished but when done will look legal.

you wont get busted on the street for smog unless: you are street racing; your car is obnoxiously loud. If your smog check doesn't pop the hood, get the miniram port matched to 1205 or AFR gasket sizes - thats the largest port I would go for an emissions motor. FYI, I passed emissions with no EGR, no smog pump, 12* initial timing and 51psi fp in Illinois with readings of almost 1/3 of the standard for my 1990 L98.
If you have a similar smog situation, get the miniram and be done with it. It's 1 piece, 12 bolts - simple. LTR and Superram setups are still 4 pieces and 36 bolts - nasty nast. HSR is nice also, but I'm not cutting my Teardrop/powerbulge hood, and besides its 2 pieces and 16 bolts

Do you want a hp or a tq motor? Do you want the car to be an awesome street driver or a track screamer? These q's go hand-in-hand. But this is the first q you need to ask yourself and then go on from there when deciding on intakes, heads, blahblah. Keep searching the archives on this board and you'll find your answers on what parts to get. You may have to wade through loads of bs, which is what a bunch of posts on here are, but you'll find a lot of your answers from just searching this board as well as www.corvetteforum.com. Good luck.

P.S. - My miniram will be on within the month (replacing my Edelbrock base and runners w/ported plenum), but I'm not worried about losing my bottom end - especially with my 150hp NX kit
