Jay do you have oil pressure behind that cap without a cam? It's all splash with the main fed from the side and no cam or lifters to oil in block is'nt it? Have you had that cap pop out ?

I have to say I'm looking forward to the finished product, that hood looks killer!  Good on the leak too, as much work as it caused the source is superficial, way better than digging in deeper at this point.

I'm glad you found a thru hole, and not one plugged with a loctited and broken bolt. Hope the worst is over now. Later, Travis

No oil pressure there, just splash.  I have had that cam plug pop out, twice before, on aluminum block engines.  That's why I like to secure it mechanically.

[jayb]

Lose bolt, eh? Did the auto flex plate hit it and make it come loose? some convertor bloom maybe while running in-car? Perhaps the normal fore-back play of the crank's thrust freeplay+convertor? That bolt head looks to be in the path of the outer portion of the flexplate.

Hmmm, I will check that, but I don't think those bolt heads are close to the flexplate.  I'm using an ATI flexplate that works with the sleeve that they use; the sleeve bolts onto the crank, and the flexplate bolts to the sleeve.  This way the flexplate is straight, not dished like a normal factory flexplate.  Seems to me it would have to move 1/4" or more to hit those bolt heads.  But I will check...

Just checked, and the top of the allen head capscrew is 11/16" away from the flexplate.  Not gonna be a problem...

Good to know!

I still see the nose of the GT.
Which was a drag week winner also?

[jayb]

That's right, Howie, I won in 2006 in the Daily Driver class with the GT.  After that they changed to rules to add a bracket race for the top 32 cars at the end of the week.  Back when I won you had to try to average 12.000, without going less than that.  On my 15th pass on the last day I ran an 11.939, which gave me a perfect 12.000 for the week.  I think they didn't like it that I spent the last day doing laps, trying for that perfect time, so now they have the bracket race LOL!

[machoneman]

Worse Jay than the laps for consistency....it was a FORD! LOL!

Only BBC and LS-7's are allowed to win on a regular basis.....you should know that!

[sumfoo1]

we get all excited if a head flows much over 300 cfm...

LS motors...

I really wish someone would do this for fords....

[machoneman]

CFE already has. Their billet Yates head outflows any LS head by a wide margin.  Note too they have other makes of outlaw racing heads and blocks and billet blocks too. The Storm King head can do over 430 CFM on a 4.120 bore SBF. No FE heads of course but...... 

Hang around the Pro Sportsman's ranks and high-end Sprint car crowd and you'll find lots SBF's running CFE's heads and (drag racing) sheet metal intakes. The heads cast or billet accept mechanical F.I. down nozzles well, a must for Spring Car racing. Btw, a really good all-aluminum 410 CID SBF with mechanical F.I., ready-to-run will set you back $35,000 these days.

Btw, if you really want a kick in the pants, check this 600 CID SBC article. As you read it, take a close look at the intake and exhaust port size, shape and spacing. As time has gone on, the Chevy crowd has slowly moved into the Ford Cleveland camp (an over 45 year old design!) as today's hottest non-LS engines sport identical heads and chambers to modern design Yates/Cleveland architecture! Heck, they have even dropped the Chevy firing order and rear mounted distributor.

And while the LS series is a hot engine, the hottest SB Chevys running in Pro Sportsman's and Sprint Cars owe nothing, zero, to the LS designs. They also have CFE type heads or similar canted valve heads ala' the Yates/Cleveland designs and they too flow well over 400 cfm. 

As a Chevy guy told me LS's are for streeters and wimps, pro & real racers run CFE! LOL!
