Heck I got a 318 magnum test mule icould throw in

Indy does bowl work for $150 a head add $150 a head into a good 3 angle valve job from them. Or just get magnum heads and a good valve job. IMHO those are the best options for a 318. For a budget head. You would have to go with a step top piston with 360 heads. And that's fine other than adding...

I agree ... for a 318 use the old 302 castings 1.88 valves or so and some good pocket porting/bowl blending pretty hard to beat. Now when the magnum heads came out they are a out of the box performance head for a 318 and probably the best out of the box 318 head. And without a doubt the best...

Yeah I think it would be a good experiment on a 318. Get some factory magnum heads. Indy will bowl blend and port match for $250 per head then add $150 per head for a valve job. At that point it's sitting around $800 for the pair then add a couple hundred for springs and retainers. So $1000...

But then again on a 318 your only going to spin to 5,500 I'm not sure you are going to see that big of a peak hp difference either

For street nasty the stock heads. The large port heads will loose throttle response and hp per second when going from 1/4 throttle to 1/2 or 3/4 throttle. The big port big valve heads yeah max numbers at wide open throttle. Drag race. Really hard to beat factory heads for street nasty. But you...

I think the cam might be a little small and gears to low for 10.90. The 380 crate motors put 3,200-3,300 pound a-bodies into the 11.80-11.90 consistently and some 11.50. With no spray add nos and maybe drop a second?

Budget heads either magnum or speedmaster. Pretty easy to get 300hp out of the 318 magnum. The la is going to need some work to up the compression with the speedmaster heads I think maybe 9.5:1 minimum to keep the heat in the chambers. Years ago there was a article in mopar action believe it...

I believe the factory 5.9 magnum is 9.1 compression. The factory 380hp crate motor used a production line engine originally. 288/292 advertised duration 230/234 @.050 .501/.513 lift for the cam . Factory dyno tested at 380hp with a 650cfm carb with a 750 carb they were over 400hp. That was...

On the early a-bodies isn't the center link the same for /6 and v8. The 2 66 darts I had the v8 and /6 were the same

I agree. There is alot of power hidden in those magnum 5.2 and 5.9 motors. I wish he would test it with a 52mm throttle body! 380hp crate motor was dynoed with a 650cfm carb from the factory and listed as 380hp. Put a 750 or 780 carb on them and they gain over 20hp. All the factory dyno...

Yeah but that's a 5.9 and he isn't running the factory j-tech he's running holley efi. A 5.2 is going to be different. Move those rpm ranges up and vacuum down. Doesn't make any difference to me have fun doing it

Well I do know lol This one will with stock computer. Maybe the hpt210 will without throwing codes if your not worried about codes go larger. The factory j-tech controllers will support alot but you will be hitting the Rev limiter before taking full advantage of the cam. Those are the options...

Or one of these if you really wanted to start getting serious lol

I think this hipotek grind would be a better option and can be ground on different lsa and a more chrysler lobed then the 262 comp grind that is more chevy lobed. Just my opinion
