Head Recommendation For An Unusual Cam

Afr 165 have 60cc chambers same as the edelbrock. I'm genuinely curious why the edelbricks are 600 cheaper. Slightly less quality? Less research so are able to make them cheaper? Do they both put out comparable gains when used on the right applications?

hello;

the afr 165's flow slightly more than the eddys but as i mentioned, that is irrelevant. parts must be matched.

i forgot why the eddys are cheaper. i know the springs are not quite as good but they don't need to be for a small cam.

air flow at different lift is what needs to be matched to a cam. the cam must be matched to compression and gearing.

you could have irom heads or plastic heads or papermache heads. if the all have the same air flow and chamber size they are all capab;e of producing the same hp.

afr's are great heads, buy them if you want them. the have 58 cc chambers so milling them .036" will be much better than milling the eddys .036". they also have the 1.9 and 1.6 valves like the smaller eddy's.

Perfect explanation exactly what i was wondering. I'll be able to afford the Eddy's sooner so that's probably what I'll do.
 
hello


are your pistons flat top or dishee.

either way you need to mill the eddy heads to 56 cc's otherwise your compression will be low.
just found out my pistons are flat. I thought valve relief and dished were the same thing

ok, cool but if you win the lotto and want the most hp, buy the afr's because the extra 2 cc smaller chamber will help and the extra flow won't hurt and will still acomodate a little bigger cam later. your flat tops still have 4 valve reliefs instead of 2 so those eat up some compression.
 
What rpm range do you think it'll pull at?

as i recall that cam has an effective rpm range of about 1000-5000 rpm, a good street cam for the smaller heads you have in mind. before you pull the heads for milling, run the math on the compression ratio, the dish volume on the pistons is available some where, and find your compression ratio first. then run the numbers on what your CR would be if you milled the head X mount, etc. you might find that your current setup has a nice 9:1 compression ratio which is fine for the street, as it allows you to run 87 octane fuel.

do you think 87 or 93 makes a huge difference? I'm currently running 93 because iv heard it keeps everything cleaner. Carb ect. And the extra $2-4 when I fuel up every other week isn't a huge issue

hello

if you want to run 93 then bump your compression up as i mentioned so you can get the most out of your engine. the extra 600.00 for the afr heads is a small price to pay over the many years you will have your car but again, the eddy's will work.

dont run 93 if you dont have to, that is just a waste of money.
 
Ill be able to afford the Eddy's sooner and also the exhaust. I'm slightly impatient. Would the Eddy's need to be port matched?
hello;

lol, i know the feeling.

i like to check the intake port alignment with the port on the head but in your case you can really just mill the heads and bolt the intake on.

Branden Here's an option for you if you want to save some money.
I have several items if youre interested. I have iron 289 heads modded and setup for a flat tappet cam. ported, 2.02 intake valves, threaded rocker studs, guide plates, comp cams 1.6 roller rockers (steel). Hardened pushrods, ARP head bolts, All that ran for only a few hours. Also have edelbrock performance head gaskets, Valve cover gaskets. In addition to all that I have a never used complete pertronix distributor and a windage tray. I'll make you a good deal on all or part of it. If your interested email me at [email protected]

This sound okay? I've heard bad things about reps. Just checking. I may save up and just be patient not sure yet

hello;

i don't understand what your question is.

i told you that 165 afrs are slightly bigger than what you need but will work killer. if you want to loose bottom end performance and not gain any top end perf, then buy the huge 185's that are run on 360 hp or more engines.

hes a rep making minimum wage. i'm an engine builder.
 
I believe you

I believe you! I was recommended to ask afr and what he said didn't sound right so I had to check. Thanks again!
