Mild Modifications / Re: Tri-Power 427 fit under 69 SS hood?
« Last post by Kelley W King on February 19, 2018, 12:35:08 PM »
While tuning my tripowers on our test engine I verified some things. This was on GM aluminum intakes. The rectangle port intake will fit over oval port heads. Use the rectangle gaskets. No noticeable affect on street driving. The oval port intake will not cover the ports on rectangle port heads. Since the bolts of course do line up I checked for an adapter but found nothing. If someone knows of one I could use one. For tuning I may try using the oval port gasket that is not cut to the intake lines but straight across but if it works I would not use it to drive because the gasket material would be the only thing preventing vac leaks. A metal plate similar to the ones for blocking or reducing the heat riser ports would work and I may try to make some by making a cardboard template and having them cut with a plasma cutter. Something else I found during testing was that the secondary return linkage on the tripower must work perfectly. Any binding or misadjustment will cause the secondary carbs to slightly open which really messes up idle and part throttle running.

We use these on Navy Ships (Submarine & Carrier) components as FME enclosures (Foreign Material Exclusion).

I did not see the smaller sizes listed but I bet they make them.

1969 - Orphans / Re: 19N509257 DZ 302 Block on ebay

Sure.

There were two US 1st Gen Camaro assembly plants: Norwood, Ohio and Van Nuys, CA. The Norwood plant initially only built Camaros; Firebird moved there April of '69. For 1969 Norwood produced about 87% of total Camaro production. The Van Nuys plant built several other cars in addition to Camaro.

At both plants, Camaro VIN sequencing started at 500001. Norwood Camaros had an N VIN prefix, Van Nuys Camaros had an L VIN prefix. From many decades of data gathering, reverse-engineered production calendars have been compiled. From these it is possible to estimate a production date given a VIN. Cars were not built in exact VIN order.

V1107DZ is a 302 engine final-assembled at the Flint, MI plant on November 7, 1968.

Camaro N509257 was final-assembled at Norwood on or about September 24, 1968. It could not possibly have had an engine built November 7, 1968.

Camaro L509257 was final-assembled at Van Nuys on or about November 19, 1968. It could have had an engine built November 7, 1968.

Yes I agree with that too. Wrong parts being installed would be a very rare thing.

Itís in CA so makes sense that it would be from a LOS car.

The block was completed on 7 November 68.   L509257 was completed in LA during late November '68, whereas N509257 was completed in Norwood during late September.   

Seems this engine could not have come in a Norwood car, but *might* have come in an LA car...

Originality / Re: gas tank straps - color and anti sqeak strips
« Last post by 68camaroz28 on February 19, 2018, 01:39:53 AM »
My question is about original color for gas tank straps for 1968. Were the straps natural steel color or painted black? Also, were there rubber anti-squeak strips between the straps and the tank? Finally, was it common for a rubberized mat to be present between the tank and the trunk floor in addition to the rubber strips shown in the AIM? This forum is excellent and I use it often as a supplement to the restoration books and the AIM. Thanks in advance.

Late reply but for future searches. The straps were dip painted semi-gloss black primer. No strips of material were between tank and straps, and there was no rubberized mat or other material other than the strips called out in the AIM. This according to our NOR 68 and other observations.

Agree, agree! I quickly looked at the stamp earlier and said yep that's it but after looking back now with Jon's comment that bracket is not for our 68Z. Me bad & sorry I mislead you!
