Yep. Think Ritter, Callies, Diamond, T&D. Then another buttload for torque conv and really beefed tranny. Ford 9 inch, back half, Alterkation front. Full cage, huge slicks, skinny fronts.... Just look at 9secRR's setup. my credit card hurts just looking it over!

I think 600ish with a good block, some oiling mods and the aforementioned girdle is not a problem. I've been beating on mine for 4 seasons. Long drives with wifey, all the cruises, and all the local yocals who wanna try me. I have a SCAT forged crank and H beam rods. I'm afraid of no man nor...

Man those are beautiful, but Ti breaks much easier than steel. I guess there's really no "strain" on those K frame bolts though. Can't wait for the weight diff.

I tried the poly locks from Mancini years ago and bent the hell out of the drivers side. Made some solids and honestly, I don't notice any nasty vibrations.

Just checked my build book. The stuff was Evaporust. Autozone.

Thank you sir! Thought it was way less.

Oh wait a minute..... here's what I started with!

Mine were horrible! I just put plugs in, tilted the engine on the stand and filled it with Derusto, I think. Let it sit a day and tilted to the other side and refilled. Rinsed it out and clean as new. Wish I save more pics, but here's one.

Sooo. Any idea how many Demon 340's?

Find a local guy to buy them. IMO they're not worth the cost to ship those anchors. Not that there's anything wrong with them:rolleyes:

Been using Pennzoil Synchromesh for years. Racing, street duty, powershifting.The whole gamut. No problems whatsoever.

Might want to try Mike @ B3Racing. I'll bet he has some laying around.

Sure will!

Plenum was done also. Not a "max effort" but sure looks way different than it did before. VERY experienced guy. Did my heads also. Honestly I'm sorry I bought that friggin Ulra XP carb. Way too much effort to get it close......fought it for 3 years. Now it's really close but.......I may be...

Oh I know what a 2 inch spacer can do. However as I said, I have a half inch hood clearance to spare. Maybe I'll get her nice and warm and go over the valves again.

Hi guys! Finally got my Ultra XP 850 dialed in as close as I can get it. Mostly thanks to all the suggestions I got from you all. But I checked all my plugs today and I have a couple that look rich. My Super Victor has been deep ported and I'm wondering if a Super Sucker might even out the...

I think if it was possible(reliably), you wouldn't see guys using exotic W5 W9 stuff to get there. I mean, once you invest in a race block why even bother with anything done by Hughes. Not a cheap shot, but a shot none the less. I fell prey to them. Once.

had a buddy with a 9 second yellow Demon. W9 stuff. R3 block. If I remember he told me his peak flow was 370 ish.... Also said it was around 700 HP. Back half car, Alterkation front. It was a beast!

Call me crazy, but I don't see a 319 CFM head making 750 HP. Maybe on their dyno:thumbsup:

might as well my 2 cents in. I think on a calibrated dyno..........248 at the crank, after some minor tuning pulls. That cam and compression are NOT "best buddies" But who cares? If it runs well and doesn't leak........enjoy it!

Rod must have reaaally improved his heads since 2016 or so. I had the first pair ever sold. At that time he took them back and said they would go back to the drawing board. He is really a stand up guy and I'm glad to hear he's putting out a great head. Good on him!

could it be killing the short side?

Come on, Turk! There's more than 1 way to skin a cat. I know guys that do it either way. Personally , I think maybe prep, the right seal the right way and a wee bit of goop on the ends is the real trick regardless if you're and offset guy or a by the book guy. we all know you can't just slather...

Well. Call me wrong. But I'm gonna continue my wrongness as long as a Superformace seal is involved. I can tolerate a lot, but NEVER a drop or drip of anything. Not my cars, my truck, tractors and especially my body!:D

Well Turk, It's a seal not a bearing. I've put together 11 engines since 2009. Mine and some friends. Always used a Superfomance "pink" rear seal and always clocked them 3/8 offset. Not one has ever leaked a drop. Way back then, Rick @ Superformance told me that's the way ya do it. So I...

Boy I hope you're gonna be ok, but I don't know how it could "look good" without a sonic check. It's like having a bad cough and your Doc looks at your chest and says "looks good". Maybe those old Mopar Jedi's know something my guy doesn't. Just hate like hell seeing a guy build a great engine...

1971 4 speed. B5 blue( now Plum Crazy) vinyl top. Factory scoops and Go wing.

Just wondering if anyone knew how many Demon 340, 4 speed cars were made. Found the total but couldn't come up with factory 4 speed numbers.

Just checked my records. Boy was I off. Primary was .070 factory. I drilled them to .078. I'm assuming secondary will be .070 also. Probably drill them to .078 also. I have been writing everything down, too. No way I'd remember anything.

Well thanks, now I gotta run over there later. I'm second guessing myself!:popcorn:
