I have been looking all over this site to see what the best intake is and i keep seeing the same thing "what's your set up" so heres my set up 86 camaro, L89, t56, 3:73, afr 210 heads comp cam 268XFI HR13(cam specs http://www.compcams.com/Company/CC/c...?csid=208&sb=0) with 1.6 rockers and supercharged (8-9lbs for now) so in your opinion what's the best intake for this setup with $1500 to spend any input is appreciated

 

Miniram is prob best match for those 210's, but you're gonna need a bigger cam to get the most outta those heads. Stealth Ram will make less top end power, but is much cheaper than the MR . Got my MR in 1995, so there wasn't a lot of options.

 

Agreed, that cam is too small for the 210's.

The 280xfi would be better

I have a LT1 intake, it was about 1/2 the price of a MR when I put it together (in 2006)

 

will the mini ram fit the afr heads??? i hear the ports on the mini ram are "off"
ill look into that cam

 

L89 ? like, a big block L89?

no sorry i ment L98 as in 350ci

 

Ok. AFR 210 heads are way too big for a 350cid unless you are pushing 30psi of boost. Even then...

I don't know how the combo is going to react, but I think it's all wrong.

Sorry.

what would u recomend??

 

I'am curious, how does the car drive right now with the afr 210 heads?

Also, I would go with a miniram to with the bigger heads but you usually see those heads on a 383+

 

the heads are in a box in my room... need an intake b4 the new motor go in

 

Might as well get a Dart block and build a 406 to match those heads!!, or sell em and get 195's. I'm about to swap AFR 195's and a XFI 280 on my ZZ-3 (finally) but mine's not supercharged. I still think 210's are too big for a sc 350, unless you're building a drag car turning 7500rpm or more.

 

I would recommend you ask those telling you the 210AFR are too big for a 355 if they've ever run that head on a 355 before.

 

No, that would be silly.

I sell AFR heads. I'd never sell 210s to a guy with a 355 and a small cam. For a small engine like a 355 you want high velocity numbers, which means an eliminator 195. Heck, most 350 builds are just fine with 180s.

The smallest engine AFR has dyno tested the 210s on is a 406,

The better question is, who recommended he go with those heads on a 350?!?

I'm sure we have some members who have bolted 210s to a 350, and think they have a great combo. Ignorance is plentiful. The 210cc head is for 550hp and up combos. If it's not making more than 550hp, you don't need 210s.

I kno your not guna like hearing this...I do understand what your saying but the high velocity thing,thats nice 4 carbed engines.. FI is a tad dif...
I like 210s on 350s with mini ram and larger cams..
I don't beileve 210s are 2 big at all. Thats the smallest head I would put on a 350. Most of this comes from the days of the carbs dubl hump heads, 3/4 race cam and 650 dubl pumper bogenators/ stumblerators..
Yes I understand most street motors dont rev much past 3-4k rpm( mine sure do tho!)..
The bigger heads are more than worth it lowmid range and up.. I'll glady give up 10lbft down low to gain way more than that in the mid to upper rpm..
I ran 210s on my 350s and even on a 400. I swiched to 235s and added more cubes. wish i had a bigger head!!
I sold/installed AFRs also.
I did a top-end swap on a 302 ford FFcobra kit car. Left the stock cam changed stock heads and intake to a short runner (minram like) intake and 205s(yes on a 302) the motor picked up from the basement to the top and gained 95 RWHP peak and close to that TQ.. the smaller heads choked her up... granted 302s have some nasty small heads buuut..
I'm not saying that the 195s are bad at all but I'm not sure y everyone gets scared of 15CCs of extra volume per runner???

 

afr195's have been proven time and time again to make big numbers on 355's. Even supercharged. Why do things the hard way or try to reinvent the wheel. You also never stated your intended use of the car but I assume its a regularly driven car with that size cam. Go with a smaller head, you will be happy you did.

 

Always wondered that one myself, I remember a old mag test before where they had 3 different size heads of the same brand and the bigger one just made more hp with no real difference anywhere else but they said it would probably suffer in normal driving. Then you kind of wonder how the LSX crowd is getting away with it.

 

Since you’re never run a set of 210AFR heads on a 350 with a relatively small cam or recommended it to anyone,, have you at least tuned on such a combo?

I can tell you in my 30 plus years of tuning and putting together customer acquired engine combinations,,, I’ve unfortunately been involved with more than just a few mismatched combinations. I say unfortunately for the customer,, not for me because it was an invaluable learning experience and I was often surprised in my earlier years at how well some of them ran.

There are plenty of people running the old 195 heads on a 350. The new AFR210 heads are fairly efficient and similar in efficiency to the older 195 heads but the 210s have the potential to make 40 - 50 more peak n/a horses. I dare say there would be very little difference in low RPM throttle response between the two heads, even with a stick and near negligible difference with an automatic running a 2800 or more stall. However, under WOT and over 3000rpm there would be a very noticeable advantage to the 210s on most any 355 application.

Don’t get me wrong,,, I’m not saying the new 195s wouldn’t be “better” in all but a few circumstances on a 350 – the new AFR195s flow as well as the old 210s and they are one of, if not the most efficient heads per cc of volume on the market. However,, I am saying the OP’s combo with the 210s being as efficient as they are,, is not going to be all that bad. In fact, I’m sure it is going to hurt a lot of people’s feelings. Certainly if I were the original poster,, I wouldn’t take a monetary hit on swapping over to a set of 195s. In fact since we don’t know if he is chasing an ET or HP goal or if there is a larger cam,, more boost,, or a larger engine planned in the near future or not,, the 210s may not be a bad choice at all.
