Thanks for the feedback. Good to hear from some other Canadian FE guys. I'm in Manitoba myself.
Good to hear that I am going a lil overboard with this whole thing. Better that than too little I suppose?
Do you guys recommend turning motor over by hand every once in awhile so springs and valvetrain isn't in same position all winter and to move pistons from sitting in same position all winter also?
What about rotating engine on stand 360 degrees to get some oil from the sump to move back up through engine and such.....
Or am I just getting a little ridiculous?

Jared.

I have a 432 stroker with a porter streetmaster and saw good  gains in horsepower and torque by adding a 1" open spacer under my 750 Holley  Dbl pumper.  Had increase with a 4 hole spacer too but the open spacer with the ported streetmaster plenum was the best for my motor.

I am about to put my FE 390  stroker motor and C6 together and am not sure about weather I need the reinforcement ring that goes with the flexplate or not?
I have a flexplate off of a 1966 390. It looks to have the markings that a reinforcement ring was used with this flexplate.
Now the 390 flexplate is neutral balanced. I am assuming that the reinforcement ring would also be neutral balanced as well.
At this point I don't have a ring but am thinking I should have one for added strength.
Is there anything else I'm missing here?
I am using a block spacer plate between the motor and the bellhousing as well.

Any help would be much appreciated.

Thanks Jared.

I have the cam card now from the builder and the specs are nothing like any of the combinations I've seen before from comp crane or luniti.
The guy who provides these custom camshafts for my engine builder likes to keep the info on his camshafts quit.  Doesn't like to share the specs.
After seeing these specs and how they are quite different than your traditional cam specs I believe he has found a unique combination with my build that has resulted in results that aren't common for the traditional stroker build.
What I will say is it is a large split duration( large split between int/exh) and has more intake lift than exh.
Also the static compression came out at 10.3 higher than the anticipated 9.8
I also think that it is possible that the Dyno could be a " happy Dyno" and my results might be a few percent stronger.
He does have a weather station in the ducting and it was set at 60F and at sea level. Standard correction.
The Dyno is a land and sea Dyno-max "pro"
I tried posting Dyno results but it says my image is too large from my smartphone.
Hopefully next season I can get some time slips that hopefully back up my Dyno sheets.

My engine shop just completed the build on my 390 strokes to 431.

1968 block bored .30 over. Oil modifications.
4.125 scat crank with 9.8 comp dish pistons.
Custom  grind hyd flat tappet camshaft
Edelbrock 60069 heads with pop shafts and stands. Factory rockers.
Streetmaster port match to edelbrock port sizes.
750 Holley DP mech secondaries.
Windage tray and factory oil pan. High volume oil pump.
Msd distributor.

Started timing at 32 total. 
488 HP and 525tq
Advance timing to 34. Gained more HP and TQ.
Added 1" open spacer under carb and ran timing to 36 total.
For best results at
547 HP @ 5400.  601 TQ @ 4400 rpm.
Real flat torque curve stayed a over 500 tq from 2600rpm.

Defiantly exceeding my expectations. I was planning for 475hp /500tq

This motor will be going into my 69 mach1 with a C6 and 3.91 rear.
Should be a lot of fun.
Thanks to all the guys on their help to answering my questions throughout the summer.
This is my first FE and I can't wait to get behind the wheel.

Len,
Since you are running the same heads, are you also running the stock rocker assembly too?
Did  you put in rocker studs?
If I can find the extra cash I will buy the pop end stands and rocker shafts but may have to just use my factory set up for now. 
Blew my budget already on stroker kit.

I went the Stroker route
I have my engine down at my engine builders and have decided to go with a 432 stroker kit.
I am using a 1966 block which has never been rebuilt. All original.
Machine shop is doing oil mod's to block.
HV oil pump and HD shaft, milodan windage tray and stock pan
432 balanced rotating assembly with 9.8:1 pistons
Cam will be custom ground hyd flat tappet to motor spec as they use a custom camshaft guy. Custom length pushrod TBD
I am using 72cc  Edelbrock 60069 RPM heads fully assembled. Oil restrictor installed. may need to open up oil return as these heads are from 2003 ( in new condition though) (Guy I bought them off used them for a few hundred miles and then changed them out for a cast set and then they sat back in box for several years)
I am planning on using my stock rocker assembly non adjustable 1.73 rockers. They appear to be in good shape still. Motor only had 50,000 miles on it. I would like to upgrade the rocker assembly but Im already way over my budget. I know there is some shimming to fit on Edelbrock intake valve position.
I have an unported Streetmaster which I am planning to have port matched to Edelbrock ports.
650 Holley dbl pumper flown to 830 cfm
6114 Hooker Headers with 1 3/4 primary's
MSD Dist and ignition
Motor will be broken in and run on the dyno at engine shop.

-The factory rocker assembly is probably my weakest point but does anybody have any experience running Factory non adjustable rockers on Edelbrock heads?
Is there anything I should know going forward with this?
-Do I still use the factory oil drip rails? Will they have to be modified to fit on Edelbrock heads?

Any feedback is welcomed. Pros and cons.

Thanks, Jared

Thanks for the quick reply Jay.
If you don't mind me asking.
How much HP and torque would the difference be between port matching and stock streetmaster to Ed heads from your experience?
I am putting thus combo on a 432 Stroker.
As far as opening up the carb plenum, those results will show more on mid to top end rpm as opposed to low end torque. Or am I wrong and it will also help at low rpm as well.

Sorry to be a bother, still learning the ropes as this is my first FE engine.

Thanks again
Jared.
