IF you could get a 6.20 Rod in there you would have a 2.06 rod ratio... and a very light reciprocating assembly (the compression height of the piston is going to be short, yielding a shorter lighter piston) which will maximize the power output, lightening the recip assem minimizes the parasitic power loss of accelerating 8 pistons from a dead stop 2 times per revolution... (at TDC and BDC the piston comes to a complete stop), therefore any reduction in the mass, having to be accelerated, is going to yield a net power increase...
Another factor is the higher rod ratio allows the engine to rev higher with less side loading... if the effective RPM's are increased then the whole mass acceleration issue becomes an even larger factor...

I will emphasize that you need to try the safestrustremover.com until you see what it will do with your own eyes you will never grasp how the product attacks nothing but corrosion, not phospate, paint, rubber, stickers, chrome, aluminum, cadmium, zinc di-chromate, & etc.

Price seems reasonable if it is as represented...

NICE!!!

Unfortunately not too much can be told from a cowl tag on a Van Nuys car.
The vin indicates a V8... the 2 gas lines indicate a non solid lifter engine... look and find the parts numbers on the frame stands for the engine... also look at the trans cross member and see what the cut out looks like... (where the trans mount bolts go through) is it oval? rectangle with a corner cut off? Get the info and reveal what you find.

A piece of 5/8" steel pallet strapping works great... should be able to find some at any manufacturing plant, maybe at a grocery store...

Use a breaker bar and make sure the trans is in nuetral.

Thanks jerry! It is a topic on a site I belong to.I wasnt sure if the 67 had it. Jerry I have 1 more paint question, the Z/28 stripes on the cowl below the windshield,did GM spray the stripes on the cowl vent panel with it on the car and did the stripe color go beneath the cowl in the wiper galley (overspray) thru the vents? If I paint the stripes on mine (black) should the overspry go under the cowl vent ?  Huh

Norwood sprayed them in place.  LA painted the cowls first and then installed the cowl and painted it.  Have photos in my book to show this. 

Could you elaborate?
I thought the Norwod cars had the cowl grilles sprayed while hanging in the window opening...
The Black 69 RS/Z with original paint definatley did not have the cowl grille on the car when it was painted... or striped.
you can see where the stripe paint overspray came though from the back where the wiper nozel cut out is located.

The best way to get the right finish is to find an aluminum foundry and ask if they will drop the parts into their vibratory media hopper (which they use to remove the sand from raw Aluminum castings) The finish is the same as the factory as that is how they got the finish in the parts to begin with.
955  Camaro Research Group Discussion / General Discussion / Rebody Z on Ebay on: June 27, 2008, 01:30:37 AM
Here is what appears to be a 69 Z cowl top spliced onto another bodyshell...
124379N613031
Ad says the cowl tag reads as follows.
Body # 278190
Trim 715                     
50-50 paint
02D
X-33
The lack of Muncie Firewall piercing and the seam sealer at the cowl well was the first clue...

Clean them in a vibratory bin or glass bead then re phoshate them with the good stuff from Palmetto Enterprises...
957  Camaro Research Group Discussion / General Discussion / Re: how fast were they?? on: June 21, 2008, 09:54:11 AM
It may take some dialing in the carb (acc pump, PV's, jets, etc), timing, and experimentation but take into consideration that Jerry McNeish's Old Reliable has been through a NHRA tear down. It's stock and runs 10's. So I am sure you could get 427 into the 11's.
958  Camaro Research Group Discussion / Originality / Re: 69 Z28 leaf spring finish/Plastic pads on: June 06, 2008, 08:25:40 PM
I have seen the liners that went the entire length of the leaf and I have seen them that were only on the ends where the leaf tips were... I would venture to guess that both types were used...
959  Camaro Research Group Discussion / Originality / Re: 68 RS/SS Camaro 396? on: June 01, 2008, 11:23:52 AM
Not really, 68's are the hardest to ID.

TRW is a manufacturer of auto parts for the OEM and aftermarket...
There is no liting of head markings for a particular location... there were just certain fasteners spec'd the manufacturers would have their own identifing marks. There were bins of certain size bolts from multiple manufacturers and it was luck of the draw.
