Is this process AKA "Parkerizing", or is that a different deal?

nitriding and parkerizing are entirely different. parkerizing is just a phosphate finish designed to hold oil. nitriding is an actual heat treat.

in my experience, and i may be wrong, but in general powdered metal, or MIM etc, are all very strong in the direction they were designed to take force, but when force is applied in a different direction the stuff is fairly brittle. The cap gets cracked off on the direction the rod is loaded in the ...

Anybody that pay $24k for 650hp has more money than brains. That's just ridiculous. I guess he paid that so he can say it has a hemi? My money is on the Chevy. It started out as a lot less money... he bought the complete iron head 426 with single 4 bbl for under $12K add dual quad setup add new sol...

rod being strong where they crack the cap, does not dictate rod strength as most would view it.

^^This guy gets it. It's a manufacturing operation, not a strength test. A few years ago, cracked cap rods were popular.

packardV8 explained it better though.

cant you just buy a 632 crate motor from gm that makes that and then some , and save a few grand?!

i was going to say something, but now i cant remember what...........................

I would have thought a short dragster would be a good idea? ( I have one of course, 180" long :) ) When Junior Dragsters started there were a ton of new kids getting into racing. Dads who previously had no racing experience put their kids in JD. Well, when they turn 18, where do they go? If there w...

I called comp cams...some dude with a name I couldn’t pronounce simply said “you need to call Summit” and hung up on me

call center in india most likely. summit will take care of you, but no one representing comp should be an azz like that.

easiest is to send it back and get another one that didnt miss QC.

my opinion is that you are looking at a mismatch. cam is in a decent ballpark for what you want, going to need a little more gear, and while the afr195 is an excellent head, its more than you need.

if those arent the pistons that were supplied to the engine builder, and they have suspicion he swapped heads, well i have a short temper and id probably knock the guys teeth out.

with small modern engines, it seems to me that most of them that run what was once considered hi compression for a naturally aspirated are now running 10.5-11:1 with a turbo to top it off, and what i see as the common denominator is direct injection. seems that being able to time exactly when a shot...

cant say as im an expert on them, but have run an ATI super dampener with the aluminum shell for a lot of years. have yet to see a downside. the pro's are it weighs less, so a little less weight in the car, and a little less rotational weight bolted to the end of the crankshaft.
