Are they forged?

Wonder what a good turbo cam would look like for numbers?

Motor would be basically hot street/drag.

My block is over at my father in laws at the moment and I'm going to pick it up tomorrow. It needs hot tanked, new cam bearings and at least .030 over bore. I figured I may do this as a side project for something to do as the $$$ frees up. Lol Wonder how that cam would react with a turbo? Also I...

What kind of converter you use or was it a 4spd? I couldn't find the duration @.050, do you know what it may be? 240ish or something? Also I think I saw the power range is something like 2800-6500?

Anyone ever run the .484/.484 purpleshaft cam in a 273? If so, how'd she run? I have the old 273 out of the Valiant just laying around and may just build it just to build it. I mean I would put a diff intake/carb on it and do some mild head work, but...wonder how it would run? I can pick one...

Thanks guys for the info! tmm, I have a set of open chamber 318 heads sitting as well. I've been following 318willrun's thread on the 318 and will probably at least do what he's done to em. I might just have the 920's rebuilt and sell em to get a little extra $$$ for the rest.

I've read phrases like "draw through" and "blow through". What's the difference?

If one were to build a TT273 what size of carb and turbos would be adequate for use? Cam would be a solid roller in the mid. .500's in lift. 110CL and 230ish at .050. Heads would be either 318 or 360 with 1.88/1.60 valves. How about a 650 with two 58mm turbos? Too much turbo?

I ran the Crane version of that in a 318 back in 2000!! Back before they jacked the prices up on the energizer series cams. With crappy 8:1 compression, stock heads with no valve job or port/bowl cleanup, summit headers, performer intake and a 650 SB DP Holley, and that cam, my 71 Dart would...

When I ported my heads. Before:

Wish I knew the socket and screw driver trick when I ported my heads!! Thanks for the tips....love seeing this kind of stuff!!

I could prob get a way with the 1.88"/1.60 set up as that equals 3.48" worth of space in the 3.625" bore. The block I'm sure needs a min of .030" to clean up anyway so bore would be a min of 3.655". This gives roughly 3/32" on either side of the valve in the bore but that's if the...

273, I was thinking roller as well....after I logged off, lol. There is a 88 Ram 50 on CL right now that looks clean and straight as a whistle for $1500. Wonder how the stock 273 920 castings would work with a valve upgrade? Chambers are closed. I have that set as well. Was thinking of...

So, I still have the 273 laying around after swapping in a 318 to the long gone Valiant and have been pondering some builds. Been thinking of a turbo/twin turbo build just to see what kind of power the little guy would make. Not sure what I'd put it in....maybe a sand rail? Dune buggy...

Hi Steve! These very heads are on the 318 in the car right now! lol

I did the same thing with my 318 heads. Here's a link to the build: http://www.forabodiesonly.com/mopar/showthread.php?t=188219&page=3 Just scroll down and you'll see the pics and what gasket I used.

You have to change the cam out as well. If you're running hydraulic lifters you need a hydraulic flat tappet cam and correct length push rods. If you're still running the factory iron adjustable rockers, make sure your lifter preload is correct as well or things will go bad quick.

Double's with a dampner? If that's the "piece you can't see" the dampner is def probably the culprit.

Like rmchrgr said, maybe the bottom of the retainer is mashing the seals to pieces.??

Ok so I jetted this thing back to stock jets 60/83 and now it seems to stumble a little bit and hestitate in different spots between 1000-3000 rpm. Also it smells like its running WAY rich which it didn't with the larger jets in it. Weird I know, lol. Its also suckin gas like crazy with the...

Yeah, I'm sure they weren't too happy when it was open headers for a few days so I went ahead and welded up my own exhaust, lol. Oh, I fixed the header gasket leaks too. :)

Went ahead and opened a youtube account and uploaded the vid, lol. http://youtu.be/szjG7fIxHgo

I thought the 308 and 302 heads had smaller heart shaped chambers?

Unusual for a pushrod to break, usually they bend, hmmmm.

Yeah, it's a 6210 model. Thanks, for the help everyone. I'll play with the timing today and see what happens. I know right now the car scares the crap outta my wife when I hammer it, lol. I'd like a little more though :)

6000ft

Even on a spread bore?

Ok, so I'm actually prob running rich in the primaries and lean in the secondary. I really really need to get a timing light on this thing.:violent1:
