I currently have a comp cams H-roller with 210/220 duration @.050 and .500/.510 lift. I'm assuming I want to stay with a fairly small intake cc on the heads I pick, but just how small is too small (or how big is too big)?

 

I would run 170-200cc with that cam.I think the best heads for that cam are the AFR 180cc heads but they are expensive and have a long wait or so I have heard.I have heard nothing but good things about edelbrock E-tec 170cc heads.Basiclly a aluminum vortec but they flow a little better.Are you on a specific budget?Do you want aluminum or cast-iron?Vortecs are usally the best bang for the buck.Also GM high performance has come out with a new vortec head that measures 175cc and has 2.00 1.55 valves unlike the 170cc 1.94 1.50 that are in the stock vortec but they are more expensive.The flow numbers are supposed to be about equal to the 170cc edelbrock e-tecs.

 

Thanks! Yeah I'm looking at Vortecs as well as Pro-Comp Aluminums and Darts on Ebay. Just haven't made up my mind yet. AFRs are too pricey for my taste.

 

Just remember, if you get stock vortec's on ebay, they will have to be modified to handle that lift....

 

The vortecs I'm looking at are the aluminum large-ports that will handle up to .550. But I think I'm going to go with non-vortecs regardless. I have a new polished vortec Stealth Ram, but I don't want to cut up my hood and I'm not sure when I'd be able to afford a different hood, so I think I'll stick with TPI and sell the stealth ram. Plus, the cam I think would work much better with a good TPI setup up.

 

stay around 170-180...no more

 

There's no reason he can't go 185-190 if velocity was kept as evidenced through a flow chart.

Either way, thank god someone is selling a stealthram.

 

After talking extensively with a couple friends I think I'm going to make the smart choice and go with AFRs, 180cc. Lead time sucks from what I hear, but it's winter soon anyways and I can wait.

GOY: Think I'll have any trouble selling the stealth ram? I'll list it here before I put it on ebay, I should have it today and I'll take pictures.

 

you wont have any problems sellin it i dont think

and 180s from AFR is a great choice.. usually 190+cc heads want alot more airflow from bigger cams and bigger cube motors....and that cam is small. not a good match. u'd have no low end power/tq....... 180's with that cam is a nice match and should make plenty of grunt

 

Got the stealthram and man is it pretty:

I also may not have a hood clearance problem after taking some measurements....What to do what to do! I'm guessing I'd see some nice gains up top but low and mid range would suffer with my cam.....

 

Great choice. I suggest calling ADPerformance as he had some of the new Eliminator in stock. I got mine on first call two weeks ago.

No, I think selling the HSR would be pretty easy...

Given that you're in Ohio and one day may want to sell your car locally (let's say up by Cleveland), you would probably want an intake with an EGR anyways. Not that I'm pro-superram or anything.....

 

One thing I forgot to mention was I do have a 2400 stall converter. will this still do well with the 210/220 camshaft, or do I need to go a bit larger? Also, where do the edelbrock runners fall in terms of type- LTR or more like the SLPs? I'd like to go with Edelbrocks if I can. Just trying to make sure I have all my parts in order. Here are the final specs on my combo, any suggestions welcome.

AFR 180cc heads, 68cc combustion chamber
9.5:1 comp
comp cams 210/220 @.050, .500/.510
TPIS big mouth intake manifold
(Edelbrock) Runners
Ported plenum
Stock Throttle Body
30 lb/hr injectors
1 3/4" MAC headers
4" mufflex exhaust
2400 stall
3.73 rear

I'm looking to break into the 12s or so. super low 13s wouldn't break my heart, either. This car is mainly going to be a show/cruiser, however.
Just trying to make sure my cam fits well with everything else I have/plan to get.

 

The Trickflow heads have a really nice minimum cross section on their 195 cc heads. They should be able to maintain a good port velocity with a 195cc head.

(bore x bore x stroke x rpm x .00353/614)=Minimum cross section.


...........................sq inches........port cc
edelbrock performer rpm ....1.43.............170
vortec......................1.66.............170
tfs195......................1.93.............195
afr 180.....................1.93.............180
afr 195.....................1.98.............195
afr 210.....................2.05.............210
dart pro 200................2.06.............200
dart pro 215................2.14.............215
brodix track 1 .............2.30.............221
dart pro 1 230..............2.40.............230
edelbrock 23 high port .....2.53.............238
edelbrock 18 deg............2.71.............266
tfs 18 deg..................2.80.............250

 

Would I need to change anything in my combo to go to those 195s? I ask because of the significant waiting list for the AFRs, and to my knowledge Trick Flow doesn't make a 180cc intake head.

 

trick flow makes a 175cc head but i'd stick with the 195. only thing i could see changing is going to a slightly bigger cam. stealth ram + 350, i would run a 220/230 cam or somewhere in there. comp cam 224/230 is a nice grind. lpe 219/219 is nice too. zz409 226/226 is nice as well

 

Heres one of Trickflows articles on the 195 heads.

Trick Flow Makes Serious Horsepower

The engine made 460hp and 450 tq.

One also nice note about these heads.

 

Okay, I ordered a set of AFR 180cc Eliminators with the 65cc chamber (in stock at ADP!). Now my question is, compression ratio. with Iron heads and my cam I was recommended 9.5:1; since I'm going aluminum, what do I need?

 

I was thinking about going with the trickflow 175cc heads and a 218/224 duration at .50 and .495 intake lift and .503 exhaust lift and for the intake tpis big mouth and as&m runners and port the plenum. How are these heads i figured the 195cc would be too big for tpi also what will the 56 combustion chambers do to the compression ration on my 350 with stock 62cc heads? Im also thinking of running 9 bolt 3.70 gears and a 2800 stall torque converter.
