Certified Stock "Qualifying Numbers"

OK - - We haven't shaken things up in a while on this board. Let's change that ....... :Brow:

I've got EVERYONE's numbers that have Certified - - to date. I WILL NOT post individual numbers UNLESS the owner gives me the "ok" to do so. I'm tryin' to figure out the best "presentation method", so bear with me. :TU:

To kick it off, I'll post my official Certified numbers, as measured in 2003 when I Certified my 1970 Olds F85 W-31 350/325.

 

Let me know who's numbers you want to see, and with that person's permission, we'll post 'em ! :bglasses:

 

wow, you mean all this time Casey has been under-stroked :jd:

 

I heard he changed from right hand threads to left hand threads and gained a stroke! :beer

 

I use washers on my head bolts. Brings the heads up just a tad higher to make it look like I've got less stroke. uzzled:

 

Casey

I would like to see Darryls numbers.

 

I can post his numbers if he gives me the "OK" .......

 

Casey

I understand :TU:

 

Here's Brian Stefina's '64 Mercury Marauder 427/425

And his I'm not asking for permission ...... I just did it ....... :grin:

 

That is only fitting.......considering you signed me up for it! :laugh:

I like the idea Case, call Darrel and get him to go for it!

I've already called Tim Clary, and he's for it too!

 

Here's the specs for Tim Clary's 1970 Chevelle SS454 LS-6

 

I'd love to see Jimmy's, Benoit's, COPO Pete's, and Bob K's..................

 

Hey -- how come Brian and Tim are running .001" too much valve lift!
Cheaters!!!! Sheesh, next thing you know these guys will be running headers. :laugh:

 

cheater :rant:

 

were there different specs for mercury's ? some of the specs i looked at at NHRA.com for the 64 427 do not match what is on the spec casey posted ???

 

Casey, you can print mine and this fall you can see how much less I will have left on the table. Jim

 

No.....no different specs for Mercury. Although they have a 14:1 compression engine listed as a 425hp with the same heads and carbs as listed for mine. Hmmmm

There are some differences yes and if you look you will also see some omissions in the NHRA listing. There is not a gasket thickness or valve relief volume listed......even though the factory engine had both....

So, some of the items had to be sorted through and agreed upon with the P/S officials.

 

that 14.1 is the hi riser head ?

the valve relief was the big thing that caught my eye , i was wondering how you got that to fly ...

 

Here are Jim Spetzman's specs for his: 1969 1/2 440 6PAK Superbee

 

They list a 14:1 425 with the high riser heads note 5 and a 14:1 with the low riser note H. Dan put the kibash on the domed 14:1 engine....

I have the factory slugs with the part number in them, flattops with as forged valve reliefs. I wanted to use them but they were cracked in the oil ring grooves.
