I know its been discussed many times before but I just want to make sure. I currently have
92 5.0 302 forged stock rods pistons
Performer rpm intake
Performer rpm cam hydraulic flat tappet
Holley 600 cfm electric choke vacuum secondaries
351 windsor heads with roller rockers arms 1.6 ratio comp cams
4.10 gears

I am looking at the 165 afr heads. What I need to know is should I go with the 58 or 60cc? And will my cam work with these heads? Will it be enough for what Im looking at going.

Im wanting to get more power but the best bang for the buck. Id rather not go with a new cam but if i'll be losing alot with that cam then Ill go with something else. I have been told those heads will just bolt on with no notching wanting to go halfway easy.
Any help would be great.
Thanks All
Aaron

Well first thing we need to know what cam not brand or type alone. you are loosing out not being roller anyway! the head swap alone will dwarf the ones you have now, depending on pistons etc and what c/r you want will determine the cc of chambers to pick!

ttocs

it would also be helpfull to know where you are going with the car. is it for DD, track use(straight or corners) or are you hoping to get 20 mpg with it all together?

The brand is edlebrock performer rpm cam and as far as roller I guess I'm confused on that. It is roller rockers. I'm new to the car. The guy who had it before me went thru the motor I'm goin off of what he has said and I can see. Haven't tore into it much just the covers off and heads I can see. It's in a street rod so not really daily driver just a weekend kinda deal.

Well if its a 93 engine then it was roller cam from the factory and i hope he want foolish enough to swap to a flat tappet cam! The cam info needed is a cam card or the specs put on here!

Edelbrock makes more than 1 performer rpm camshaft.

Well I went to edlebrocks site and they show only one performer rpm cam for the 302 and here is what the card says
DURATION AS ADVERTISED INTAKE: 270° EXHAUST: 280°
DURATION @ .050 INTAKE: 204° EXHAUST: 214°
LIFT @ CAM (Lobe) INTAKE: 0.28" EXHAUST: 0.295"
LIFT @ VALVE INTAKE: 0.448" EXHAUST: 0.472"
LOBE SEPERATION: 112° INTAKE CENTERLINE: 107° IDLE VACUUM @ 1000 RPM: 16"

IMHO, that cam is very puny to use with heads.
I think I'd use way more cam than that.
Look at the stuff Competition Cams has out or maybe Trick-Flow.

Well not everything is listed on there site or maybe i have looked upon a mis-print!
That will be usless with those heads.
Here are a couple suggestion:
CCA-31-442-8
CCA-31-452-8
CCA-35-349-8
CCA-35-510-8

You can call comp and they will cutsom cut you a cam for 310.00$ if one of those look like what you want but you think the lobe sep should be changed call them and ask about it!

We need things like car weight what you want to do with the car rear gears poweradders, intake, carb size, exaust sizes, tranny type and ratios ... to get you closest to what you need!

The cheapest route is the TFS stg 1 cam.
