Heads and cam

'95svtcobra · Sep 1, 2004

just wondering what I could expect horsepower wise with AFR 185cc heads and ford racing E303 cam on my 95 cobra with the mods below??? I put 248hp and 300tq to the wheels as she sits. thanks!!

Get a custom cam or another off the shelf cam and you will see better gains. Those letter cams are decent, but there are better cams out there.

I have no idea on what to expect hp wise

i wouldnt go with 185cc you would prolly get more power out of the 165's

I dont believe that....Build the motor around its components. If you get AFR 185cc's then get an intake and cam that will support them. Plenty of guys have dont it.

Guys with the TFS twisted wedges (which flow more than 165's) make just as much power and guys even do a stage 1 port job(like fox lake's) and still get great power.

I dont see why he should not run 185's, but i can be wrong. Feel free to explain, i would love to gain the knowledge.

compession

EDIT: with the e cam witch he said he wants the 165s will make more power but if he gets a cam that will support it yes the 185s in theory would make more power

compression? please explain more. Is there a big difference in combustion chamber size? Does the runner length/size change compression?

I just find it hard to believe that you will make MORE power with the 165's. If you build it right, i dont see why it should not be just right at that 300rwhp that everyone with AFR, TFS, Edelbrock, etc are at.

we are not talking peak... we are talking average power.

and why the hell woudl you buy the most expensive street head and then throw the cheapest cam at it?

that just makes no sense

95YellowGTbeasT · Sep 1, 2004

did you read my edit????, guess not YES, if he gets a cam and builds it right it will be right where everyone else is at.

Sorry If i stepped on your toes, but if he gets the 185s he is gonna need a new intake aswell.

Nick

'95svtcobra · Sep 1, 2004

what cam do you suggest then if I get the 185cc afr's???

95YellowGTbeasT · Sep 1, 2004

custom cam no doubt

Nick

'95svtcobra · Sep 1, 2004

like comp or crane???? help me out here.... the only reason why I wasn't gonna get an intake is because I may get a kenne bell roots stlye down the road and didn't wanna spend the money on it. I guess I could get my intake port and polished?

95YellowGTbeasT · Sep 1, 2004

i dont know, thats why i said the 165 because your intake will make enogh for them to flow but i dont know if it would have enough for the 185's it would sorta be like a stock gt

HAHA, we must have just made the post at the same time cause i just read your original and not the edit. Alright we are on the same page, with the E cam you would make more power with the 165's.

BTW, get the custom cam from FTI

'95svtcobra · Sep 1, 2004

well ****. I don't want that thats for sure! lol

95YellowGTbeasT · Sep 1, 2004

i wouldnt want that either

Nick

In my [so very humble] opinion ...

GT40 heads flow just well enough that I would keep them, and get a power adder instead.

95snoozer · Sep 1, 2004

if you dont do a power adder, just do an n-41 AFM cam.

WhiteDevil · Sep 1, 2004

First thing is that 185s have 2.02 intake valves which really make Piston to Valve clearance a problem on a stock shortblock. Second yes he could get them and get a big intake and cam to work with them but what the hell is the point. You cant safely spin the stock shortblock high enough to make power that high and make it worth while. So get a good cam and the 165s and call it a day.

185's are the BETTER choice. The only down fall for you is you'll have to notch the pistons to fit. Get yourself a real cam, please! A custom cam or even a well chosen comp xe cam will make good power. I'd lose that cobra intake and get an rpm or an rpm 2 and port the inlet for a 75mm TB and run 1 5/8" longtubes.

Damn im good at making power

You prefer Edel. RPM 2 over TFS track heat? Just wondering cause i have not heard much about the RPM 2
