I built a stock spec 340 with redone J-heads upgraded to 2.02/1.60 but not ported. Put in a Comp XE268 and could not be happier. It is in a 68 Barracuda and that car pulls hard. Used an RPM Eddy and 750 Eddy carb. It is a 904 Auto, factory "hi-stall" converter, 3.55 gears, cheap headers and...

With the added lift of the cam, do you think I would have any issues using the much thinner gaskets?

Thanks for the reply. Yeah, I am trying not to let this thing snowball on me. I was not to worried about the heads, but you make a good point. I was planning on running the 1008 Fel-pros at 0.039 compressed. There are some negative posts about the Mr. Gs. You ever had any trouble with them?

I totally forgot about the plenum gasket deal. I will check under that intake. Even though I am using a dual plane Mopar Carp intake on my build, I would like to know what caused the things I am seeing.

Heads and the block after I vacuumed and cleaned up

I have had a 5.9 Magnum out of a 98 Ram that I traded a set of wheels and tires for over 8 years ago. It has sat in my garage ever since just waiting for an opportunity to live again. It is supposed to have come from a running truck with 80K miles. Fast forward, I have acquired an 84 Ram...

What is his User Name here?

I have a 340 with X heads. What is the best bang for the buck for streetable roller rockers? I also have plans to update to a set of Eddy Heads I have had for a while sometime soon, so I would want to use them on both heads if possible. Thanks, Jamie

Did the OP ever get the 318 in his car????

What are you putting the motor in? What is your plans for the car? If it is a street car.... If you don't aready have heads, I would look for a set of later design swirl port heads or even consider putting a set of Magnum heads on it. I did a motor years ago for my dads 68 barracuda. I...

I have a lot of interest in this thread. I have a bone stock 318 72 Dart Swinger, 904, 2.76 gear that needs some help. I too was thinking a cam and 4bbl was in my future...... Would love to know how this works for you! I was thinking about this cam..... Lunati VooDoo Hydraulic. Best mild...

What are the cam specs for the two cams? Stock 318 2bbl and the XE256?

What is the estimated HP gain using this cam over a stock 318 2-bbl cam in the OPs setup? How will MPG be affected?

Any updates? How did this handfull of parts wake up the "teen"? Are you happy with the results?

That is cool......

What is the full specs on your motor? What brand and type pistons did you use?

Thanks guys!!! This is exactly what I was looking to learn.

Yes I do! That is not the question......

The local shop that I am planning on using for the maching of my SB stroker, does not have any torque plates for a SB mopar. How important in a street engine is it to hone with plates? This shop has built or done the machining on several SB mopar stroker motors that I know of personally. Each...

Is this the pan you used? http://www.cnc-motorsports.com/product.asp?ProdID=12416&CtgID=12400 If so, any issues with the stroker crank and the baffles/scrapper? Thanks,

Thanks for all the input 340sFastback!!!! I am re-thinking the flattop decision.......

No problem.... We are all here to learn and DROOL!!!! Good question.

340sFastback, Thanks for the reply. Can you give me the specifics about your build? Also, any results like dyno numbers or 1/4 numbers? How is the idle quality? Also, do you have to do anything special to install a retrofit hydraulic roller cam. BTW, I love your car! A Green Fastback...

Maybe I should rethink my decision on using flat tops and thus 11.6 CR. If you can make 533+ HP with Dished pistons.... That may be the way to go that way I can for sure use pump gas.... Moper, Can you help me out with this comment you made? So if I go down in compression and keep the bigger...

I am assuming dished pistons at zero deck??? If so, WOW..... How is the idle?

Hey Mopardude.... Tell me about your motor!!! Will it run on pump gas? If I could get those number out of mine, I would be :toothy10:....

Thanks for all the good info to all and Moper..... I have got my eye on some Probe SRS flat tops. They have -5.5 cc valve reliefs. Assuming a zero deck, .039 thick gasket with a 4.18 dia, a cylinder bore of 4.040. This would give me a CR of 11.6. NOW here is where I need help.... Even though my...

I already have a MP crank and Eagle H beam rods.... Just need pistons, rings and bearings for my bottom end.

How "rough" will the idle be for a XE295HL in a 4" stroker motor? I thought if you stayed in the 250 ish range @.050 it would have nice idle characteristics for a street car......
