You could probably do a quick casting numbers check on the 2 heads to see if they are the same casting number, this would reduce the doubt of interchangeability by at least half if they are the same.
Sure thing! Glad to help out.
Looking good! How much shrink allowance are you using for your pattern?
Yes, you can lock the advance like they do in race engines. Just tig or mig the plate from functioning is all it takes.
You probably have several lifters frozen(stuck or rusted)in their bores that are preventing you from being able to reinstall them. Pull the side cover off and this will allow you to see plenty.
What are you needing ported vacuum for? Just curious.
I've made many billet Stromberg 94 and 97 carb spacers that were used on vintage engines that needed a vacuum source and were drilled just under the carb base to provide it. Most all early multi-carb...
That is sharp looking! It would be a shame for them to let it fall through the cracks and rot away or get sent to the crusher.
Which style carb base do you intend to use? The 2GC has 2 different styles, one is just a simple rectangular base and the other is shown in the link above. They both have the same bolt pattern, just...
No, that phenolic material is not really meant to be used in that fashion, nor is it strong enough. You really need a metal(aluminum)spacer/adapter for what you are needing.
That guy doesn't put a lot of thought into his parts and they could be made much more functional. Are you limited by any thickness restraints, I notice his are 1" thick and 2 pieces stacked together,...
The idea that forged pistons are noisy has long since died. In modern times the advances in technology have all but eliminated that issue. Yes back in the 50's and 60's when forged piston technology...
You're doing an awesome job too! Keep it up, I really enjoy reading your build threads.
Billet is cool, but you will have a market of only about 1 or 2 people. For the same effort I can make all the patterns and cores to cast a performance head that can have a much broader appeal from...
If some one has a bad cylinder head they could send me i'll be glad to give it a shot. Im fixing to machine a test combustion chamber for my Chevy 12 Port Head patterns, so I have my focus on heads...
I finally have been able to acquire some 263 valve covers to get dimensioning from. So its in the works for both the 320 and 248/263 engines.
You are experiencing a common problem many people have when trying to use a repair manual that is 60+ years old combined with parts made in modern times. Brand new parts just aren't made to the same...
Ok Doug, thanks.
Thanks Doug. PM sent.
Just curious if any one knows for certain if all Straight 8 timing covers are the same. Can one for a 248 fit a 263 and also fit a 320, or whats the differences? Thanks
You can pull plug wires off of the engine one at a time while its running to help narrow down which cylinder it likely is. Worn wrist pins can happen in any engine, but usually on high mileage ones...
There is a Chevy Inliner member that has a blow-thru turbo setup on a 292 engine with 3x2's on it, so I don't see why you can't also....it makes almost 900 HP also!
With the low compression you have already, it might be a good candidate for a small turbo, or even a twin turbo setup with around 5-7 psi boost.
Sounds like a nice build. Are you going to do a build thread somewhere so we can see its progress.
