that's a bummer hope thing are ok.

What happened? There is a great buildup But no delivering... I myself have a 273 and was hoping for more information

From what I'm reading, when it gets right down to it the 273 performers The "best"running the basics............. 3 C's Cam carb and compression As long as I got the 4bbl pistons a a small chamber head(with a littlie work done) And a mech cam under .530 all shound good?

Thank you I will keep that in mind, is a 68 dart 270 is dated around april 67 I think

Many thanks for your opinion and input. I got those heads and that manifold on the shelf"didn't think they were Worth a **** really." I'm not sure how many miles are on this engine and I need to see How much taper is in the bores .hence the not liking the .060. Overbore This engine is my work...

The reason why I ask is , I have. Sets of 974s ,051s even 302s and the 920s I am trying to get the most "bang for buck" with my 273. I know the chambers are larger on all of these heads compared to the 920s I can cheat some of the cc's with A thinner head gasket using one of the other...

Looking at lifts from .200 to .500

Looking for stock flow numbers for the 974 heads. Anyone have any info would be great

Maybe some one asked already. Do you have headers? Is the starter getting "hot". Maybe need a heat sheild for the starter. That is what comes to my mind

I might be wrong but don't the 273 pistons come out .020? With the 302. Head wouldn't that cause a issue?

Was thinking about using the .284 .528 soild from MP. All the info I found on the D/dart camshaft seems to be the same except for gross lift. The lob sep is .112 And I belive the overlap is 60 degrees. After checking at the specs, looks like MP copied the cam but changed to just A single...

Back in those days everyone did a bit. Most of them under estimated the Horse power.

Seen it. But a duration of 284 at .050 seems not to sound right, with only a Over lap of 60 degrees and 112 lop seperation . I adimit I know enough to get me In trouble but it don't seem right to me at all

I haven't forgot ,look everyday day to see if anyone has more info on these cams I guess their was only 50 of these cars built,not sure how many are left or how many Still are running the old Camcraft cam in them . I can't ask anyone to pull it just so I can get a copy of it. The only time I...

Was a 2bbl but the slugs have 4 valve notches. I believe they stick out .0129

I have a 68 dart 270 as far as I could tell this engine has never been opened Up. How far out of the cylinders do the pistons stick out.... Btw 2bbl 273 automatic. I was of the thought that they were down in the hole Insted of out . Thoughts?

Nope. I know that they are out there. Wish I could find one

Called a local cam grinder out here and the Cam Dr book don't have a listing . Thanks for help though it was helpful

I called Camcraft. Very nice people but they are not the same Camcraft from the 60 They started in the mid 80. 40 plus years have past,,, Looks like I am going to wing it ...lol

It seems to be the hen's teeth.. all the other info can be found:banghead:

I am looking for the duration @.050 of the old camcraft cam that was used In the D/stock dart in. The 66 273. Can anyone help me out on this?
