    Are Speedmaster Heads Good? I've Heard a Lot of Bad Press on Edelbrock 340 Heads Lately

    I have been thinking about getting some performance heads for a while. Maybe I should have bought some Edelbrock heads before the quality went downhill. I understand that since the company was sold, quality control has left the building. I have a few questions: 1. Where are Edelbrock heads made...

    Anybody here have a small block with those Hemi heads they used to sell?

    I remember many years ago (probably about 20) some company was selling hemi heads for small block Mopars. I really liked the idea, but they were expensive. Plus, if I remember right, one had to buy their expensive intake. Does anybody on this forum have one of those small block Hemis? Wouldn't a...

    Which header bolts go through to the water jacket?

    I hate to ask this, but it's been a long time since I've pulled the headers for new gaskets. I was thinking it was the back one on each side. Thanks.

    Does A Big CI Stroked SB get to a point where It is hard to keep cool?

    This may sound like a dumb question. I have seen stroker small blocks up to 440 CI. Are they hard to keep cool on the street? Here is my thinking. A 440 big block has more internal coolant capacity (bigger block, more space inside for coolant passage), so a 500 HP 440 would have more coolant...

    Power advantage between Ford 351, Mopar 340 and Chevy 350??

    I was thinking (which I sometimes do) about these three similar displacement small blocks. I know they arrive at their displacements through different bores and strokes, but I would think they were somewhat similar. Here is my question. If you took each of these engines and installed cams with...

    At What Point is a Solid Cam Better Than a Hydraulic Cam??

    I obviously know the difference between a solid and a hydraulic cam. I was just wondering at what point for a non-race car does it make sense to switch to a solid cam? Or does it for mostly the street and maybe a little strip? I am talking non-rollers here, and small block. I run a Comp XE268...

    Does Line Honing change the crankshaft's centerline?

    The way I understand line honing, you shave a bit off the top of the main caps and then hone until the crank holes are perfect. But won't that make the crank's centerline a bit closer to the camshaft's centerline? If so, wouldn't that make timing chains loose and pistons sticking up into the...

    Got my complete MSD ignition setup today

    I finally pulled the trigger on a complete MSD ignition system (box, coil, distributor and wires), and it came today. Summit had a sale and it was only $640. I plan to bump my cam a bit and add EFI later, so I thought I would do this first. The Mopar Performance electronic ignition (orange box)...

    Wouldn't it be best not to mix brands on some parts?

    I am a pretty good mechanic. I have built several engines. I built the 340 in my 69 Barracuda up to about 375 HP about 20 years ago, and it still runs great. Here is my question. Sometimes I read here where someone has a cam/valve train problem. They say something like, "I have a Comp cam, Erson...

    What About Edelbrock 340 Heads?

    I have been thinking about getting a pair of Edelbrock Performer RPM heads for my 340 and having them professionally ported. Here is my question. Every time a member asks which head to use, it seems that everybody says W2, W5 Brodix, blah, blah, blah. I don't think I have ever heard anyone say...

    A few questions about stroker small blocks

    For quite a while, I have been seriously considering putting a stroked small block in my 69 340 4 speed Barracuda. The current 340 is built to about 375 HP now, and it is a blast to drive. I have even rat holed some money away for one. But the other day, I was cruising FABO and came across the...

    Destroked Small Block?

    I had a friend who had a 69 Z-28. It was a great car, it was pretty fast, it sounded good, and it revved up nice and high. At 302 cubic inches, I believe it was just a destroked 327. I realize that people build stroker engines for more cubes, torque and HP. I was just wondering if there was...

    24 years and counting on Western Auto Starter

    When I got out of the Air Force in 1993, I worked at Western Auto for 5 years while I went to school to get an MBA. While there I finished the first restoration of my 69 Fastback, and bought a WA Lifetime guarantee starter for the 340. It sits right beside (very close) to header tubes, and is...

    Leaking Thermostat Housing. Thinking on billet with O Ring

    Just noticed my thermostat housing is leaking a bit around the gasket AGAIN. I have an Edelbrock Air Gap intake and a chrome (I assume chromed aluminum) housing. I went through SEVERAL gaskets and varying amounts of RTV and thought I finally had it sealed. I have read a lot of bad press about...

    Lifters: To Soak or Not To Soak

    OK, I am confused. I have seen on MANY TV shows where they say you need to soak hydraulic lifters in oil before installation. I have also seen MANY shows where they said do NOT soak the lifters (most recently tonight; which prompted this thread). I have probably built 5 motors, and I have always...

    Need Help With Engine Diagnosis

    Sorry for the long post, but I figured you’d need specifics. 69 Barracuda, 340, 4 speed, 3.55 gears. About 15,000 miles on 12 year old rebuild by myself. Comp 268XE cam lifters and springs, headers, Eddy Air Gap, 750 CFM Eddy and MP ignition system. For years, I could melt the tires with...

    Opinions on MSD Ignitions

    I have a moderately modified 340 (about 375 hp) in a 69 Barracuda with a 4 speed and 3.55 gears. I currently have a 20 year old Mopar Performance electronic ignition setup in it. It runs OK, but am I leaving something on the table. I am thinking about buying an MSD setup: 8545 mechanical advance...

    Line honing crank journals

    If I understand the line honing process, the cap's surface gets ground down a bit and then they are bolted and torqued to the block and honed to the correct diameter. Here is my question. If a few thousandths is honed from both the cap and the block surface, wouldn't that bring the center of the...

    Roller Lifters in a 69 340 block

    I really have 2 questions: 1. How difficult is it to put a roller lifter cam in a 340 (69 block); and, 2. Is it worth it? I have a 69 Barracuda with a warmed over 340 pushing about 375 HP. It has Comp XE268 cam, Eddy Air Gap, Eddy 750 Carb, Headers, 4 speed and 3.55 gears. Although I have...
