408 build (needing a second mortgage 😯)

Frankie,
I'm in the middle of a 408 build myself but right now mine is kind of on hold until it warms up a little more. I need to take my block to the machine shop to be checked out and I am also taking my EQ heads in to have a little porting done. If you look at the link in my sig it will take you to my thread. I started off building a low budget 360 and ended up trading it for a 408. So what happened was that the 408 I got had about 6,000-8,000 miles on it. So I started to tare it apart and clean it before I did anything else. I had traded short blocks so it was easy to clean things. But of course as things always happen something always seems to go wrong. I was pulling the pistons so I could wipe down the cylinders and dropped the #2 piston. As it hit my garage floor I knew I was screwed. Sure enough I had broken part of the piston skirt off. So I had to order a new KB piston. While I was at it I decided to get new rings and went with Total Seal piston rings. Once there isn't anymore snow on the ground and temps stay 45* or higher at night I can start working again. My engine isn't going into a Dodge truck though it is going into a Jeep TJ.
If you haven't gotten your cam yet I have a brand new cam I am looking to sell . It is a Comp Cam also. Here is the info for it:http://www.compperformancegroupstore...CAMRFHRCC92-02
Let me know if you're interested.

I wish I would have remembered you were selling that cam. I would have bought it in a heart beat. Unfortunately (for you at least) my cam should be here this week.
Here is a picture of my cam specs:

I still don't understand the differences of what changes what where, but this was decided after several calls and emails with comp. Hopefully I communicated what I was after well enough for them to dial me in.
I'm looking forward to your progress when it thaws out again.

Here is a link to my Photobucket page. for some reason I cant get this place to take my pictures.
Franks 408 picture page
When i started rolling the block around on the stand today for clean up and general inspection, I found an extra part. There was a spray nozzle from a pressure washer poking out of the water galley between #5 and #7
. It took me a few minutes to realize it wasn't suppose to be there
... and a few more minutes to figure out what the heck it was.
After about 2 hours of fishing, i finally got it. The spray side was just big enough that it wouldn't come out of the galley.
I'm not sure if it came from me steaming the block before i took it to the machine shop, if it was the machine shop, or if its been in there for almost 20 years (doubtful), but it was a project getting it out.
Anyways, that's the update for now. Enjoy the photos.

Yes, the rotating assembly was balanced before it was shipped. It cost an extra $80 for the heavy metal to get it balanced, but the price through hughes is for a balanced assembly... less heavy metal.

Apparently they installed the power-washer nozzle too..... 
Ya know, I don't think I have EVER found anything strange IN a block I got back from the Machine shop........ Of course, I have dropped stuff into engines before...... which can be quite annoying... (and expensive....) Having to pull a motor out of a van so I could drop the oil pan to get the bolt I dropped out is TRULY a pisser.

Found out that was all me today when I took the tip to work... oops. Lol
Talk about adding insult to injury, ouch.
On a brighter note, I got my oil pump and pickup tube from Richard @ HiPoTec today and ordered my heads.
Wound up going with the same set that Wildman ordered ($890/pair). The base EQs with stock valve sizes. They're suppose to have one piece stainless valves and springs to handle my .48 total lift cam... and a swirl polish? Guess I'll see what that is when I get them... probably the first part of next week. David said it was 3 days delivery to him, one day to prep, then send them to me via UPS ground.
This set isn't on their ebay page, it is a call in order only. They did say that they've had enough demand that they're going to add it to ebay soon though.

Supposedly they do. When I asked about it, they wouldn't give me a straight answer. Part of the trouble there is I don't know just what to ask, so I may not have gotten my point across.
I did ask point blank what the difference was between these and the cheaper heads they're advertising. David said these breath better, and they don't have to do as much work on them for the larger lift cams....
The way I understand it is they have to mill certain areas around the spring pads to take heavier springs on the cheap sets. I almost want to buy one of the cheapie heads to do a comparison, but I don't have $300 to spare.
Anyone want to donate? Lol

Thank You Very Much!
The chart is rather enlightening. Looks like the EQ heads REALLY start to shine between .3 and .4 inch lift.... which, coincidentally enough, is right in the neighborhood of the stock cam. I am curious why they don't flow as well at minimum lift though......
And the 2.02 valves move the 'better flow' numbers even higher in the lift range. Interesting.........
My conclusion from that would be, the 1.92 valves are actually a much better idea for a truck motor, that you want to squeeze as much torque as possible out of.....
Still and all, adding another (almost) 50 cubes to your engine should make up for any losses down low........
I am oh so torn.
