Yep, just sell them on this board. Lloyd is in the metroplex and I'm sure would take them for a couple hundred. I might take them too and maybe try my hand at porting

P.S. this is unported.

 

From a couple of independent sources, the Dart "180"s actually measure out at 189.8 (+/-1cc).

Right now he only has a Corsa exhaust as a mod, but I'll be degreeing in a CompCams CRC (Constant Radius of Curvature) custom ground cam when I pull the engine to begin the work. I'll be narrowing down the cam specs as soon as I pick the heads.

Am undecided at this point whether I'll go 1.6 or 1.7 NSA RRs. New LT4 T/C set. A stall down the road.

Yes, LE is only a few miles away from me.

I'll put up a For Sale post after I pull them. They'll be going for a "song", just to keep them from being under-foot.

I tried finding Dart's posted numbers but couldn't. I found numbers from other, independent, sources, but not Dart's.

Could you post the link so I can have a look-see? I may see something else that'll help me make my decision about them.

Thanks for that info.

I went with the Darts, had mine ported by LME, get better guide plates then what Dart sends you and make sure they come with a set of plugs for the passages you don't use. I used the GMPP guide plates with mine. Also keep your tap and die kit handy, we had to fix one of the bolt holes for the intake, wether it messed up from Dart or at the machine shop, I don't know. I didn't go all out on the port work since they're going on a stock short block with an off the shelf cam, but mine flowed some thing like 288CFM at .650 after port work, but can't race a flow sheet. Good luck other wise.

 

Thanks for that info. I located dartheads.com and just finished spending a few hours reading a lot of the messages posted on that Forum.

I still didn't find Dart's posted flow numbers yet, so I posted asking for someone to point me in the right direction where they can be found.

If you don't mind sharing, what are the cam specs you went with? I'm waiting to get a firmer handle on the flow numbers before I decide on exactly which one I'm going to order.

I know I'm going to order a custom CompCams HR from their CRC lobe series - either 3100 or 3300 series of lobes. I'm considering having it put on 111 LSA but that's still up in the are too - I know it'll be between 111 and 114 depending on the duration specs I choose.

I'm going with a GM LT4 timing chain set because it incorporates some desireable design features, the cam gear in particular.

Thanks again for your response.

I know what you're after, but because this is a public forum there are those who want to offer an opinion or perhaps a better suggestion, which is where I'll offer mine.
Reputable shops will not need your heads to complete their work. You call, put in your order, they take a pair of heads and do their "magic", they send them to you charging full price, you swap them out, you send your heads back to the shop and they deduct a core charge.
If you want this experience as well as a great heads/cam package that doesn't have "rumpty-rump idle; vibration to loosen my fillings; a dog down low; emissions concerns..." then I suggest the Lingenfelter LT1/LT4 heads/cam package which will easily net over 400 flywheel hp with emissions components in place and will have a power curve which behaves very close to the stock powerband.
Juuuuuuuuuuuuuust a suggestion.

 

Sorry, no link. The numbers I posted are from a hard copy FAX'ed to the Speed Shop from my local distributer.
I won't have "stock" flow numbers for MY heads as I am having them CNC'ed. I will post the flow numbers when they're done.

 

Jake,

Does this help?

Thanks for those, but I'd already found and download that information. However, I've still been unable to find Dart's numbers, so I went to their Forum, Dartheads.com, registered and posted a message asking for one of the guys there to send me a link.

I really appreciate your help in this, Scott.

Thanks for that. You know, I've been screwing on these suckas since Hector was a Pup and one of the major enjoyments I have is in selecting my own parts - that's just me.

I like doing all the research, reading and listening to all the differing views and recommendations and, finally deciding, based on all that and my personal experience, which road to travel. Don't get me wrong, I don't ignore the advice and recommendations of others, but I'm sure you'll agree that there are all sorts of differing views on what parts to use, etc., etc.

So, basically, what I like to do is assemble all the available information in a big pot, then sift through it, decide which ones I want to use, then break out the debit card, LOL

So, my point is, while I don't readily disregard the package deals that so many shops, builders and companies offer, for me a lot of the fun is in making my own decisions. For guys who haven't spent as much time in the barrel as I have, the packaged parts is a real benefit and would be an excellent move for the.

Yea, in doing it "my way" I might not always nail it, but the fun's in the trying. In other words, for me, it's not so much the end result as it is the getting there. Hell, I'm now 64 years old and retired, so I need "something" to keep me busy, LOL

I recall back in the day (when I was young and limber) I use to change cams so often I could almost do it blind-folded; always seeking that slightly better profile. In the process of all that knuckle skinning, I learned what works and what doesn't. It was fun then and it still is.

Just so you'll know, your suggestions were well received.

Thanks again,

Jake

Hey Jake,

Are you after a complete flow sheet from Dart then? The first link is from Dart's site and lists numbers @ 0.500 (257/172).

Maybe email or call Dart and see if they'll send you their data?

After browsing the thread you had mentioned with Bret's ported numbers, I'm starting to get interested......

Edit: You're quite a nice Dad to be doing all of HIS homework

Regards,
Scott.

 

For all the research you have done and your background, i'm surprised your still interested in buying aftermarket heads....


You dont need them. Simple. Stock heads with CC503 cam will throw down 340whp and thats over 400 crank hp all day long.

If you were looking for more than 350-360whp on stock bottom end, only then would i consider doing aftermarket heads or ported stockers.

For a daily driver, you really should use the stock heads and just cam it.

 

I tend to agree somewhat. If you are only planning to run Dart's out of the box, then you could certainly get a stock casting to flow 260/175 for less money.

The Dart's do look like a great casting for porting potential which to me would be the motivating factor.
