Finally getting back to my engine.

I picked up new lifters and uncut chromoly push rods from The Type IV Store,

I'm thinking I should go with better than stock valve springs for my 9600 RAT camshaft?

Bump for spring recommendations!

Also, any work I can do myself on the combustion chambers like adding a radius to the edge from the flat to the combustion pocket?

Let's see if this one gets ignored as well (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/lol-2.gif)

Can the stock Type IV oil pump deal with a remote cooler all the way up front behind the bumper if i wanted to go with a GT type setup?

I think that HD springs were used on most the Raby cams with a more aggressive ramp.

The springs that came with mine were single coil, HD springs.

Be 100% positive that you use the right lifters for your new cam. Ceramic lifters are best, or the correct Raby / LE lifters for that cam. Otherwise you can flat spot the cam in no time flat. Learned that the hard way. :-(

I think that cam would prefer to have dual or HD springs. But if you email the Type4Store they should be able to tell you what's recommended.

Called and got someone that had the cam card!
Recommended dual (with a little hesitation which makes me nervous?)

Specs:
.335 IN
.400 EX

Duration 290°

@ .050" 252° IN
@ .050" 254° EX

Looking at the Web Cam catalog, it looks similar to the 86a (below) except for intake lift, I hope it was a misprint or I didn't hear her correctly. Web Cam doesn't show any cams with that small of an intake lift!

QUOTE
.435/.435 290°/290° 252°/252° 86a N/A N/A
00-232
Strong mid and upper end performance for high performance street engines. WEB CAM mechanical lifters required. Requires
Performance Valve Spring Kit, and New Lifters Part #00-265.


I think I will measure the lift just to make sure.

I just did a quick measurement using my HF digital calipers.

Lift for stock cam:

I = .277 , E = .255 so the intake lift is .022 greater than exhaust.

9600 cam:

I = .310 , E = .384 so the exhaust is almost .070" greater than the intake? Turbo cam or okay for N/A?

More exhaust flow to compensate for the type 4s poor exhaust flow characteristics. Common idea with a variety of implementations.

Back to your original question, I suggest you evaluate upgrading your oil pump (higher flow) in tandem with Tangerine's oil pressure relief valve upgrade.

Thanks, ordered the Tangerine Racing oil pressure relief spring upgrade.


Only oil pumps i could find are the 30mm units:
https://type4store.com/products/oiling-syst...hicles-486.html

I also found an article for using the stock oil pump and making it better than as delivered:

Started to clean the engine again to get it ready to put back together.

I Bought a media blaster kit to hook up to my pressure washer....

I am using baking soda for the media.... 1st test and it works pretty darn good, just messy (more so the water spraying back at me ) I'll have to fix that!

There was a lot more build up between the webs before I gave it a blast. Just plain water out of the gun didn't do squat.

Megasquirt question...really EDIS related. Older MS2 V3.57

I screwed up and bought the wrong EDIS setup, I bought the -8 version instead of the -4 version.

I still think I can get it to work correctly as long as I mount the sensor 50° as per EDIS-8 requirements.

The stock V8 firing order is 1-3-7-2-6-5-4-8 (wasted spark pairs are 1-6, 3-5, 7-4 and 2-8)
As long as I connect to the correct coil I see no reason it wouldn't work.

Any possible damage if I didn't hook up the other 4 spark plug wires?

Will I damage a coil if it is only firing on one side and not as a pair?

Good time to convert the heads to dual plug? (IMG:style_emoticons/default/smile.gif)

I'm pretty sure you can just set up your MegaSquirt board with a second ignition driver and then dispense with the EDIS altogether. Less components to break/die. Simpler wiring. Simplicity. (IMG:style_emoticons/default/wink.gif)

Thanks I'll look unto that. Didn't really want to go with COPs.
