Maybe a bad batch! Lobe lift is .3150 with a 1.6 rocker is .504. I doubt .004 is the tipping point. They advertise .550 capable. No shimming. Ran them straight outta the box because of the low lift number. My fault for not making sure. It's Edelbrock for Pete sake, not ebay coke can heads. It's comi...

I did some reading, apparently the heads are cast in the states but the valvetrain parts are crap. Also they advertise .550 lift capability but it's highly recommended not to go over .500 cause the 1.250 springs can't handle it. And definitely no rpms over 5500. Ugh!!!!

The E-Street stuff is offshore parts to my understanding. They are trying to compete with all the other cheap Chinese heads. The machining is done here. Since I was trying to keep the port size to a minimum, the E-Street was the best option. The heads perform wonderfully but the hardware has it's is...

So I was running the boat today at the house, I start it every week or so and let it come up to temp, letting it idle when BANG!!!! Sound like a rod came loose! Thought it was coming from the right bank, pulled valve cover and nothing out of place. Started it several times to try and locate the hamm...

Fuel injection definitely.

4.00" stroke in my Windsor. Zero clearance issues. 16% larger displacement. 14% by way of stroke. 4.030 on the bore. Makes over 500 lb./ft. of torque at 3000 rpm. Here soon hope to put it back on the dyno with the 2 barrel injection. Should make more power!

Probably just the limitations of the rig and power plant at this point. Stroke that mofo! Night and day guaranteed.

Keys the 2 barrel is the way to go man, I'm tellin ya! Wish they had it when I first bought mine 4 years ago.

Fitech 2 barrel on a 408 Windsor DD. Had Fitech 4 barrel but DD runs better on 2. My throttle response is killer. Cold start is non issue with injection. Sniper is good, as is FAST. Stay away from MSD. They have had issues. I've had experience with all of them. They are not as plug and play as the c...

Yeah I'm not gonna be much help here, I wandered into the 21st century with fuel injection years ago! Other than tuning on a dyno or on side job hot rods, I don't mess with carbs much anymore. To easy to get it wrong, believe me after seeing dyno numbers on carbs that were supposed to be "TUNED", wi...

ICT are equally as nice pieces.

Earl's Performance has these trick billet aluminum fittings that replace the OEM steam lines. They use 4an hose and fittings so they can be custom fit to any setup.

Dayum that took a turn for the worst right quick! Sorry I asked the question about the thermostat.

Not sure 200-210 is the answer. I believe the higher temps from the manufacturer has to do with emissions. My 13 Silverado runs 210 no matter what I'm doing. I like to see mine running between 180 and 200. Fitech sets the closed loop at 172. I run a 180 stat. I do however believe 160 is too cold, bu...

Probably make more power with higher temps. I run a self learning system on my 408 windsor and it doesn't get to settle down til it hits 172 temp.

Crack the steam lines on the heads. Should get most of the air out. One of these help bleed air out while running. Curious why no thermostat, fuel injected motors like to have steady regulated temps.

Ted how many hours would you guess were on each before there was a problem? Same builder for the 2?

Yes sir conventional wisdom would certainly agree with that idea!!!!!

I have often thought about some type of external thrust bearing. The problem I have come up with is having to put a spacer block between the flexplate and crank to allow a thrust bearing to be in between. On sbc with the starter bolted to the block poses a problem with pinion gear engagement. Sbf is...

Swamp so think about this! Those 3 engines you referenced have the thrust bearings located in the middle of the block like sbf. I'm wondering if these locations hold up better to a thrust bearing located at the rear of the block. Now if you have noticed the OEMs have all moved the thrust bearings to...

Ok I wonder if it's a sbc design flaw? By that I mean how they oil. Were those engines fresh builds or pull outs?
This is not to bash one side or the other, just curious if it's a common problem and why.

First off I started this thread off in Airboat Talk since it includes both types of power. That being said I wanna know why everyone thinks automotive thrust bearings can't handle the pressure of a prop like aircraft thrust bearings? Other than the fact that aircraft have a floating thrust bearings ...

Clevite makes .001 undersized bearings. You can use a standard upper and a .001 lower to tighten them up .0005. Or in no.5 use .001 upper and lower to get back to .0025.

Looks like an aluminum block so align hone isn't an option.

Or in my case a CM DD Ford guy, THE TRIPLE WHAMMY!!! LOL

Most importantly an LS engine is just a Windsor wearing a Bowtie!

Heavy, so we currently do not have the adapter brackets for BBF. Stuska has them in stock and would probably a week or better to get them. That being said, we would like to see the print outs of your engine's dyno session to see if the values look correct for afr's, egt's and bsfc (brake specific fu...
