Check "pure-gas.org", for ethanol free fuel in your area. You may pay a little more for it, than say 10% ethanol gasoline, but may well be worth it! Here in Michigan, there are countless "pure gas" stations, due to the amount of water we have here (think Marine gas).

Maybe this thread could help others. Sticky maybe? I know I did a lot of searching for the parts needed to remove the 90 degree adapter and change over to the remote set-up. This thread has all the Info I needed. A big thanks to all who chimed in on this thread!

Purring like a kitten!

I'm impressed!

Looks good! Nice, clean, and neat.

LOL! I hope so!

Welcome back, Brian!

Try using 2 gaskets. Never had a leak with 2 on there.

Sweet!

I'm not sure who makes them, but there are "thin" intake gaskets available for re-worked heads. I recieved a pair from a member on here, OU812 (Brian @ IMM engines).

You stated that the carb is a NEW Edlebrock 500 cfm carb, correct? How about something simple, like the choke idle speed being set too low? What RPM's is it idling @ when first started, cold/choke on, VS. idle speed fully warmed up/choke off?

I've seen others on here recommend Edlebrocks and Indy/RHS X-heads for similar builds. I bought a pair of Indy/RHS X-heads prepped by IMM engines, for a 340 build i am doing. Hopefully others will chime in with more info for you. Steve~

If the price is right. You could always trade/sell the items you don't need/want for the ones you need/want. Others more in the know will chime in.

You can do a budget build on a 340/360, and get lots more horsepower than our old 273's ever made. I've got almost 7K into my 340, and everything is new except the block and crank. I would find a reputable machine shop that knows Mopar. Don't skimp on the machine work. Hope this helps.

If all 3 leak in the same places, it could be the valve covers/heads. Valve covers could be bent in those areas.

Congrats! You must be very proud!

Listen to what Brian (0U812) posted above. He knows what he's talking about in regards to the Indy/RHS heads. I bought a set from him, with the PRW roller rockers kit. Although I'm still in the mock-up/clearance checking phase, these heads with the beehive springs and the 1.6:1 roller rockers...

I could be very wrong, but I am pretty sure you could use a 750 Holley for your 340. I'm sure those with more facts will chime in.

From what I read on other posts, add/subtract shims & spacers to center the roller tip on the valve. Also read that .010"-.015" clearance between each pair of rocker arms. Hope this helps, in conjunction with what others above have posted.

I was just searching for the same info. I'll look some more and get back with you.

Sounds alot like vapor lock to me.

Lonewolf, that's funny!

Take a look through the tech forum. Lots of people on here have/are building some very potent 360's.

I had my cast 340 crank internally balanced. The shop had no problem doing it as well. Find another shop.

Yup, agree with others. Very suspicious sounding.

Much appreciated advice guys, thanks! Kinda thought I'd be pushing the envelope with the stock stamped rocker arms, just needed some reassurance from my fabo family. Again thanks to those who replied, and your "thanks" buttons have been pushed.

I was wondering what valve spring could the stock LA rocker arms handle (hydraulic flat tappet). Cam lift specs .507 int, .494 exh. Spring recommended is Comp #995-16. 1.437" o.d., seat load 115 @ 1.700", open load 336 @ 1.150". Any help or suggestions is greatly appreciated. Steve~a.k.a...

Don't know the part #, but IIRC, it should be the "street hemi" orange your looking for.

Do you have a 90 degree oil filter adapter? Some of them get cracks and will leak. Tends to leak directly onto the passenger side exhaust, down by the trans.
