Why?☺ @RAMM have you calculated intake port size/length for this camshaft? In my car,i think this is a boring engine☺ it will fall over before 5000, not any fun to accelrate when you cant rev it out. Sure its cool when you stump it, it light up the tires instantly.

Once in my lifetime running a 318 in a w250 crewcab with edelbrock performer camshaft,i milled my heads 080 (2mm) ,i could feel the torq boost with the buttometer :thumbsup: ..did not mill the intake side,so barely got it on.

yeah, but I see alot of combos with BIG street camshaft (260-270@050) and the car is not going fast = combo mismatch. its a normal problem to overcam the combo. then you loose all over. The butt-o-meter may say its working, because the engine is a dog and come on strong when it first do, but you...

listen to RAMM, he know what it takes to get there:burnout: according to pipemax and Larry meaux, this Hughescam is done at 6000. the intake lobe is rated at 5500rpm, and exhaust a bit higher. also, the time the valve is open (duration+lift) also limits the powerband to about 6k on the...

the Hughes camshafts has generally a tight lsa, this will hurt Your goal because its really hard to make 500hp below 6000rpm in a Stock stroke 360. bigger lsa will bring the max Power higher up in the revs. I may set it up in pipemax and see how far you may get With that camshaft:-)

you have to be pretty experienced to make a presice bore@hone in 2 hours? I mean, the Block has to be set up and ajusted, or does the new machines align themself? anyone here work at a machine-shop? how long time does it take?

how is it possible to bore&hone for 175?? its time consuming, whats Labour/hour rate? here in norway its like at least 500! I just bored and honed a stright six diesel , total including tax = $830....

well, as a mechanic, I actually see People that should not have wrenched on they own cars as well! Im not defending shortcuts here.. Its not just the mechanics that destroy Things... :-) another thing is that at home you may have time to wait for that spare to show up, at work, everything takes...

its free hp to get as low as possible pressure inside the engine:-)

big cam is like a dump valve on turbo cars. cool at first, but then its only enoying(spell??) in the long run, you will be most pleased With a smaller cam (2steps actually) than you first desided. beenthere. If you only have those 2 options, I vote for #2 personally I would choose a cam With...

sure! intake port has to be seen as a package from intake valve to carb. if you have a intake that is tuned to 6500rpm but Your cam peak lobe rpm is 5000, I Guess you get the peak far over 5000, but the engine will be a dog, and does never reach its potential. I dont think exhaust size is a...

AJ/forms : you have some Nice info! but how do you know the intake port isnt limiting your cams top end power? overcammed engines does usually dont react well at timing changes. its really scary to adjust and compare engines thats not exactrly the same, too many variables. there are 2 ways to...

I guess the majority of eddys in the world is running OOTB. they say you need at least 10 happy customers to add up for one dissapinted.. we newer hear about the 99 of 100 that just put them on and drive away ;-)

Well, guess it wont hurt power at least, but if you have a fairly stock camshaft now, i dont think youll notice much. Guess the power holds on further tho. You better start a thread and ask for the optimal camshaft for ootb eddys:-) Good luck Edit: last post sound like a wey healthy plan...

me too, but 400 may be reasonable. I did see a 360 Stock bottom end with turbo on youtube that dynoed about 600hp, holding up according to owner. 600 hp may hold just fine for short periods, I mean, you dont drive a mile With the N button depressed...:burnout:

Mike, first, Im a fan of your work from the other side of the pool. You make mopars scream. You said earlier that nowadays the rings seat after just one pull. May i dare to ask if that is caused by better macine-work or the piston/ring material package or both? Iwe always done backyard...

Hv pump take more hp to run, normally a stock pump is enough. It seems like this is a 6000rpm max engine?

reversion is caused by a too big intake port... the air is going in sooo slow, that when the piston turns at bottom center(and the valve is still open) , there is not enough energy/speed in the air to keep it running into the engine so the air stops up, and starts to flow backwards ,until the...

for what Application?? 318, 360, 408? Stock camshaft? 250@050? just asking:coffee2:

no im sorry, im not that experienced. I do the most of the work myself... Im just a ordinary Family guy With no spesial Income. If OPs needed head rebuild is 1000-1200$ and New head are $1400, Ill to say BUY THEM! I agree they are better in all ways over std heads, but I was thinking if he...

Is it worth 1400 dollar? ( how much for rebuilding the 302??) I say he may get what he wants from the 302s:D

A well ported j head has nothing to do on a stock cammed 318, but with the correct parts it would be perfect:-) its all about the combo...

they claim good port speed for a 410ci, this means...too big for a 318 with 3.23. You need alot of cam to take advance of the port size. It "wont" work (well) with 3.23 If you have the money, you buy them, and a cam that fits 3.23, then ask them to epoxy the runner to get correct air speed for...

thats Nice info!:) do you have a 360? lately I have read Magazines that want to show a tight lsa as the "New" trick to make big Power... they seem to peak rather high even With tight lsa, but I Guess some of the rpm capabilities lies in the heads. on a Stock J or x head, the story would have...

Yeah, but that Stock camshaft peaking that high does have a terrible powerband!? no power anywhere...? you may size the intake track to "ram" at a spesific rpm, and I believe if this area falls right in the cams sweet spot, the gains are much more that ramming outside of the optimal area...

This is a 99% street engine. saterday night spesial:D we have wery few tracks in norway. maybe some time, I take it to the strip.

Jup, i second that, but the thing we all strive for is to get the "combo" correct, this will give you the most horsepower!?? You need to build the engine around the camshaft or else you can not get it optimal. Sure it will run, but you may be way off the best potential. Crackedback, i think the...

thanx for the try:-) I guess you need a houndred-thousand dollars-programs to be really close is simulating power, because there are ,like you say,so many factors involved:-) but I was mainly searching for the peak rpm, and your program shows 5000. thats interesting. pipemax 3.2 that I have...

Im going sheet metal intake with pipemax length and size. injection. -procomp alu heads ported to meet pipemax flow and size stock stroke,rods. sp pistons.

if pipemax tell me camshaft lobe rpm = 5300, but on dynopapers a 408 peaks at this RPM. who is telling the truth? pipemax or the dyno? I bought the camshaft some years ago for another project, the new design is 36/42, but my camshaft is 237/242@050 on a 108 lobe sep. .548,.555lift @1.5...
