Do bypass regulators bleed off fuel pressure when the engine and electric pump is off? Reason I ask is I have a heat soak restart issue and I know it will help cool fuel make it to the carb if it’s plumbed after the carb but if it doesn’t release pressure in the line at shut down i may be...

I’ve got a brand new spectra fuel tank about ready to go in my 71 demon along with a new 3/8” sending unit. I run a Mallory elec pump and will be using a return style regulator to help ease fuel boil over when parked hot. I will run a 3/8” return back to the tank. The sender has the small...

Looking to replace my engine harness for my 71 demon 340, I remember picking one up at M&H on the southwest side of Chicago, or am I dreaming? Are they in California now? Where is the best place to buy ? Would rather not deal with year one unless they have a Christmas big discount. Thanks

I run about 5 btdc and want to go back to a factory distributor from my MSD mainly for the vacuum advance. I welded the slots many years ago when I ran more initial so I need to lengthen them a little to get to about 30 total. I think this chart is pretty accurate. Just want to make sure, thanks .

Now that I have a 6 pack on my car when it sits hot for more than 10 or 15 minutes it is hard to start, guessing it has to do with all that mass because I didn’t have this problem with a 4bbl. I run a electric pump so no problem when driving. Can I replace my regulator with a bipass regulator...

After 23 years of street brawling she’s a little worn and tired! Time to give her some love.

Looking for something other than the M/T valve covers I have. Preferably finned early 70’s. Thanks

Are they interchangeable? I seem to remember them being the same u bolt and hole spacing, but not sure.. thanks

Just the three, one plastic cover has crack, could be glued, needs a good cleaning. $30 + shipping

Getting ready to order tank and sending unit, has anything changed as far as quality in the sending units? I need a 3/8” supply with a return nipple to run fuel back. I’m going with a spectra tank. Thanks

A-body bars wanted, the kind with the built in shock plate. Thanks

For A bodys I believe. Anyone use something like this ?

Arch is gone on my 40+ yo SS springs. I run 28” tall drag radials so I’m thinking +2” springs would be best. But let’s see some pics with tire size.. thanks

I’ve got the offset shackles on my demon but wondering if they make longer rear offsets to raise the back a bit? Thanks

My 71 demon 340 came with front drums, buddy of mine has a K/H sbp setup with rebuilt calipers, new rotors the spindles, and upper control arms. . I know I’ll need a manual disc/drum master, new wheel bearings, probably a adjustable proportioning valve. Anything else I’m missing? Is this stuff...

anyone know where one can be found?

Orange valve covers !!

must be in good to excellent shape, thanks

Anyone know what the extended length is on the A body drag shock? I have a set of new Monroe gas matics that have been on the shelf for several year that are 26.25” E & 15.5” collapsed. Thanks

Just getting started on a set of 1972 j's, milled the guide down .200 and about to profile the guide. was there a long thread about porting j/x heads? I can't seem to find it. anyway, can the guide tail be removed completely? This will be going on a somewhat stock appearing 6 pack, intake has...

Looking for vintage finned valve covers for my SB. Not M/T since i have those on my engine now.

What's the go to valve for a set of J's? these heads will be home ported, guides will be shortened in the bowl area by about .200" . Cam will be in the high .500 to .600 lift area. Is Ferrea still the go to? I want the 11/32 stem. is the .100 longer valve standard on builds with high lift...

Hi, looking to port a set of J heads and add 2.02’s with 5/16” stems. Any flow to be gained by milling the guide down in the bowl between a 1/8” to 1/4” and blending vs just blending as cast?? Thanks

681, no ld6b stamp. What’s a fair price? Friend of mine wants to buy mine, not sure I want to sell though LOL..

Looking to dump the electric pump and go back to a stock simpler type set up. Will a stock 340 pump keep up with 450hp 6 pack? Any good aftermarket hi volume pumps that do not need a regulator? Thanks

Thinking of upping my game, not interested in hearing about how I’ll make more power with a 4bbl, had many 4bbl/two plane / single plane combos, my ported intake with mechanical carbs pulls just as hard if not harder with my current setup. So share your 11 second combos!
