Are The ls valve stems the same length and diameter?

I need a 2.02 valve for a r/t magnum head and maybe an exhaust valve for it as well.

I have a set from a 2001 360 but I'm all the way in Mississippi I would ship them if you would pay the shipping cost I wouldn't charge too much for them

Haven't heard about the pro Max Magnum heads is that something new? How did they compare to the RT head or Edelbrock heads or are they just a stock replacement head like the EQ heads are? I think I've heard of the promax in big block and maybe La aluminum heads wish there was more pictures of...

What do you mean a two-piece balancer? You mean one that the balancer and the pulley are separate pieces? Where did you find one at and/or what did they come on because I need one myself or just a balancer really so I could bolt an old style v belt pulley onto it

I have a set of new hooker 2" primary fenderwell headers I would trade for the tri-y headers what size primaries are they? I haven't ever really seen partial fender well headers before except for maybe custom built ones otherwise I've only seen ones that either go through the fender Wells or...

Speaking of the Keg intake and nitrous, I’ve heard of the plenum pans blowing off with nitrous backfires before...

Now I know a 318 and a 360 are different and Ive always known the 318 to be “bulletproof” but it should give an idea of how the magnum’s stock pistons, rods, and crank are... I got a buddy that had gotten a Dakota chassis and he put a magnum 318 in with over 100k on it and it was all factory...

Flow numbers for these heads with 2" exhaust pipe lift range .100-.600 .100 .200 .300 .400 67/56 142/107 204/156 253/198 .500 .600 287/233 307/257. I for some reason was thinking I'd need a lot or lift and this and that, though more lift would mean more flow, but is...

Ah ok I got you now, I was just thinking I'd have to order a set of pushrods and all for a cam I'm planning on throwing away, which honestly I don't even know where the 509 is at the moment, I've been In the process of moving since me and my ex split up it may still be in the shed at my old...

Yeah those dips are to clear the float bowls on a Holley, the drop base air cleaners are more designed for engines with high rise intakes which are normally running holleys, I've made one fit an eddy before I don't remember if I maybe had to massage it a little or If maybe it just happened to...

Doesn't the drop base have provisions (dips) in it for the fuel bowls on a Holley? Spin it around to where the dip part is over the electric choke part, I've done that before myself, depending on the base it may work for you

Like I said get the most power out the engine I can with what I got, really not spending a lot of dough, most of everything I have is stuff I've got laying around, I've pulled off other engines and cars, or traded for, a while back when I was looking at buying heads I was planning on getting a...

Well the 509 is what I pulled out the engine so I know it clears. I know once I buy a cam and get the pushrods and everything for it I'll of course bolt heads on, use some putty and check clearence on top of the Pistons I just want a ball park idea of what is enough to make the most power...

My biggest thing with this at the moment is picking the right size cam, sorry about writing a book but it has some points so bear with me here I picked this 400 up a while back as a "running engine" for a cheap price, the guy pulled it out of his super bee charger to put a 440 in, he got the...

Sorry I didn't read everything above, yeah by time you're buying Pistons, Ross, and everything just go ahead and get a stroker crank done deal

Why not get the kb quench dome Pistons? They have a step dome, they'll give quench with the open chamber heads and will give a good compression increase, the stealth heads chambers aren't much smaller than stock heads, at 84cc so the compression gain wouldn't be much at all... Instead maybe a...

Trunk pan, location?

The low deck motors can spin a lot of rpm, with the proper combo they'll spin like a small block, I have a 400 myself and a while back was doing a lot of google searching and there's a lot of guys were talking about spinning stock bottom end 383s and 400s well past 6grand some as high as 7 grand...

I'd go with a Hughes whiplash it'll help raise the compression, if the tm6 is what you have, it's gotta be better than stock right? If I had a stock intake, or the tm6, I'd slap it on there... Shave those 906s down some port match the intake to it, I have a Holley street dominator that would...

Most kbs I've found were around $469 or more thru summit then another $300 in bearings and rings $550 for a balance job just for a little bit more compression. Would it really be worth it? I was actually thinking spending 80 bucks and get a little shaved off the heads and as small as the...

I remember reading a while back where these guys took a motor home 440, put on a good set of ported 516 heads, 509 cam, intake and headers, and played around with different parts and made close to 500 hp without going above 8:1 compression, said the compression could've been more but they did a...

Heck I could actually still see hone marks in the cylinders the guy I got it from had pulled it out of a charger that he bought as a project car and he wanted to put a 383 back in it so that's what he did and I picked the 400 up for 275 bucks and a 2 hour drive off craigslist so the motor hadn't...

And when it comes to time for a tear down and replacing Pistons I'm going to go ahead and make it a stroker is my idea, right now I'm going to get it together as is to get the car up and going, then I'm gonna build the bottom end in the future, stroker, girdle, cross bolt main caps, and nitrous...

Yeah bores are perfect, no ridge, and the mich checks everything good and the crank and all looks like they did a balance job on it. It's still stock bore size I'm thinking it was a low mileage rv motor and they did somewhat of a build to it they had a 7qt milodon oil pan, tapped the oil pickup...

I have a question regarding lift myself, my heads can handle .700 lift but I'm running stock type Pistons in a 400 with no valve reliefs Pistons are .100 down the hole which in a way could act as somewhat of a valve relief. Would I be ok with a cam in the .545-.557 range?

. The stock rocker arms are actually a little less than a true 1.5 ratio and I'd say you have just enough room for the .533 to clear if it wasn't hitting it until the lift reached .550. With proper valve springs I'd say you're good to go

On big blocks I've seen guys run the .513/.533 lift lunati without the valve guides being cut down

I remember a while back seeing multi layer steel head gaskets that were like .025 compressed and were around the price of regular head gaskets I don't remember if it was mopar that mad them or who? Since then I'm having trouble finding them, I've never messed with cometic head gaskets but aren't...

I couldn't find a calculator online that didn't ask for piston dome height, etc. And I don't know all those numbers all I know is the bore stroke and how far. They are in the hole, which really measures .90 something but I rounded to .100 just to give it the benefit of the doubt. Do you have a...
