Cam-Heads combo

Need some advice. I have a 350SBC stock block and heads, short headers. I have a HSR ready for installation. I was thinking on replacing the cam and heads. I was wondering if a set-up with the following specs would bring close to 400HP.


Cam
Hydraulic roller
Intake- 220
Exhaust- 224
Int lift- .528
Int exh- .536
LSA- 112


Heads
Chamber-64cc
Intake runner size- 195
intake- 2.02
Exhaust- 1.60


Or, if there is a COMP/Edelbrock combo that would bring close to 400HP that can "fit" my HSR please let me know. Thanks in advance.

Re: Cam-Heads combo

What exact heads are you looking at. The specs you listed for the heads are 50% of the equation for what they would actually do.

Thanks for the quick response. To be honest. I found those specs on a 350SBC crate set-up I found online. Obviously, my knowledge on the subject is limited. LOL! I just want to keep my block and HSR intake and increase hp by replacing cam and heads. What would you recommend? I don't mind a mild idle.

Re: Cam-Heads combo

Budget? Bout the cheapest alum you can get are dart shp stuff or the flowtek heads from speier racing heads

195 head is good size. That cam will do 400 crank easily. If you want 400 at the tire its gonna need alot more

Re: Cam-Heads combo

What is your budget for heads?


The comp XFI series is one of my favorites for what you are doing

Re: Cam-Heads combo

I wanted to keep it below $1000 but that seems to be unreal. I'd say $1500-1800 for the heads. Cam, I'd say $300-450.

Re: Cam-Heads combo

For that kind of money AFR 195 heads can be bought and you will not be disappointed

1195$ best bang for buck imo. I think Import casting but quality valves/springs/machining etc

Re: Cam-Heads combo

Ok, so, in order to achieve close to 400hp I would need 195, or maybe more?
How about chamber, valve lift? Again, my knowledge is limited. As far as chamber, is more better? Would a COMP 280XFFI work well with a 195cc or 200cc head?


Saw this Dart http://dartheads.com/dart-product/iron-eagle-23-200cc/. Would work with the 280XFI from COMP?


Just looking for a nice combo. Thanks all.

Would any of these http://www.compperformancegroupstore...ode=RLERCAMXFI cams be a good match for the 200cc from Flotek?

Re: Cam-Heads combo

The dart heads would work well also looking at the flotek heads there is a big increase in flow between .5 and .6 lift so they would be able to take advantage of the larger lift of the XFI cams specifically the 280.

No you can run a smaller head like a dart 180 or afr 180. They will do it. I just like most 195 heads with the hsr, gives room to rev abit and for future builds.

The key is making sure you have the right spring package and good components. Generally i like afr heads for their hyd roller spring packages. But you pay more for it. Back in the late 2000's you could get the heads for 1300$ or so. Now idk what they are, 1500-1600?

The 268 xfi cam will get you 330-350 whp most of the time with a afr 195 head. Thats over 400 flywheel hp. The 280xfi will get you much closer to 375-400 whp and is alot more aggressive sounding on a 350.

Like to see nearer 11:1 comp with the 280. 10:1 ish on the 268

Re: Cam-Heads combo

I am surprised nobody has brought up Promaxx heads, they are designed after the old Patriot brand heads, and have excellent flow, and a killer casting for an excellent price.

The 200cc heads flow 280 cfm and can be had for under $1000 bucks. Best bang for buck there is out there. Of course everybody would love to have a set of AFR's but there are other options.

Re: Cam-Heads combo

I love my AFR 195cc heads on my TransAm. I have an LT1, but performance wise the SBC vs LT1 is near identical. 231/239 on a 110. Cam is too much for daily driving. Its steerable, but if you get caught in a traffic jam you might want to blow your brains out due to working the clutch.
