Clevelands and FE are done, will start my first 5.0 !

Did some small adjustments for the cam and came out with the following character for the 331.
The numbers are not real, I know this, but I use programs like this one just to see if the character of my planned built will fit my needs and the defined parts will correspond.

I kept the 112 lobe separation but adjusted a bit the duration to 266/274 or 216/224 @.050.

The curves will more or less look like this in theory ...

Simulations are nice, but don't rely too heavily on them. Horsepower and torque curves/peaks depend a lot on cylinder head flow as well, and until you get the heads in house and flowed (never go by advertised flow numbers), you really can't say with certainty where the numbers will fall.

That looks like the specs for a Comp Cams XE266HR. It will be a fairly mild camshaft in a 331.

Back in town with news. All the bits and pieces are collected, here and screwed to the bare metal. The 331 and 347 shortblocks from Keith arrived and fulfilled all my expectations.

My one was ordered with a matching flywheel and damper.

For the thermostat housing I have choosen a Performance Stainless Steel one, the heater hose fittings from the same company will arrive in the next few days.
I used adjustable guide plates from CompCams instead of the supplied AFR parts delivered with the heads as well as CompCams hardened pushrods.

The thrust plate is the one from Precission Oil Pumps with the needle bearing, the oil pump and drive shaft are from the same company.

All fasteners are from ARP, the main studs are the ones for the windage tray to use them for mounting the pickup tube.

The rear sump canton oil pan is baffled, has trap doors and integrated scraper and clears the stroker kit.

The Cobra open letter valve covers are a must for me so I had to install milled down valve cover spacers to clear the scorpion rollers.

The complete thing is topped by a Weiand stealth and a MSD Atomic with a Cobra round air cleaner from Tony Branda.

Now the engine is waiting for the painted MK IV chassis and body, to be delivered by Wednesday next week latest.

Some pics for the gear heads:

Some other detail pics from the assembly process: Checking crankshaft end play ( which was fine, sorry Keith, the nitpicker is back)and cam end play. The new timing cover was completely deburred in the water passages because the tool parting lines where massive and I just don't like it this way.

I checked nearly everything but not the supplied AFR rocker studs and I payed for this.
Two of them had the threat not worked out completely, the pitch looked like not rolled correctly and more like a trapezoid thread what I found out the hard way.....
As I applied the AFR recommended torque to the rocker studs the thread in the heads gave up immediately and I had to remove the left head to fix the damaged threads with TimeSerts.
Have the more actual AFR heads inserts in the threaded holes for the rocker studs?

Timing indicator is mounted and finally adjusted to measured and approved TDC.

Nice small detail, my name "UWE" on the counterweight , the second short block was ordered for "WILLI"...no, not the one to be freed..

These are the only wires to be used with the Atomic EFI.

The next update will be done after the thing is back to life.


BTW, I have a rare pair of 351 Cleveland Valve Covers available with "SHELBY" and the "SC" script on top. It is mid 70s original Shelby aftermarket stuff for the Panteras or Cleveland powered Mustangs.

UWE, that looks like it's going to be a very nicely matched combo. If you don't mind I'd like to hear your thoughts on the Atomic once you get it running. I'm in the process of changing my 462" FE over to the Professional Products TBI which seems very similar.

[westcott cobra]

Will share my experiences with the MSD but not before middle or end of July, sure.

[westcott cobra]

Some update about the car and engine. The complete assembly is ongoing.

[Mando]

Absolutely beautiful!

Regards.

Back with some late update. The 331 has seen 700 km till today and runs great. The MSD Atomic is the easiest system I have installed ever.

It was so easy to istall and set up. Great!

The complete thing looks like this now:

[YerDugliness]

Quite keen on the hood scoop....mine is "short" and I cannot run a decent air cleaner.

Do you have any dyno numbers on the 331???

How do you like the 165's? I would like to rebuild my box stock 5.0 with a set of AFR165C's, the factory "competition" model. Might put a stroker in it, if the block will stand it I would go with a 347 stroker, though...might use that longer rod/piston combo recommended by someone a page ago...at any rate, your ride is one primo A/C and you should be incredibly proud!

Cheers from the U.S.!

Thanks,

The 165 KC ported AFRs were ordered and delivered before the decission for the 331 was made.

They were planed for a stock 30w rebuild. For a future 302 based stroker package I would go directly for the bigger heads.

Dyno results, If my job allows it, can be available middle or end of next year.

I have some plans to optimize the exhaust system behind the JBA headers.

In the MK IV the air cleaner lid sits more or less 1/4 " below the hood and the scoop could be eliminated, the scoop is not necessary for clearence if you go with a intake not higher then the Weiand Stealth and my Carb/EFI-aircleaner combo

With the FE or Cleveland in my former car I needed the scoop for use of the small round aircleaner in the turkey pan or the big oval one.

UWE, thanks for the feedback on the Atomic and your MKIV is drop dead gorgeous!
