Got a little bit more done. Intake manifold on. I am not 100% comfortable with this setup. The intake runners on the cylinder heads are quite tall, and the top of them is very close to the top of the intake manifold runners. There is perhaps 1/8" of overlap where it seals. This should be sufficient but it still does not give me the warm and fuzzies. I will start a separate thread about intake recommendations.
Valve covers on. It is really starting to come together.
I would have buttoned up the oil pan however I ordered the incorrect oil pickup screen and it would not fit with the OEM pan. I have a replacement coming in today so I hope to get the motor sealed up by tomorrow.

That is awesome! That puppy should humm along nicely!
Don't forget to put a tack weld on that screen to the oil pump ! ( ask me how I know that ) lol
Got a question about your timing gear setup !
What is the gear between your crank and cam held in there by ??
Is it just the fact that it is sandwiched in between them or are they held in place on the block ! I haven't built anything with more than a timing chain gear setup !
Yea , it's been that long since I put my 454 together!
Also what heads are those that your using? I vaguely remember you talking about them some time back !
I will be sure to put a tack weld on the screen...I need to break out my new welder anyway =)
The timing gears are simply held in by the fact that they have nowhere else to go. There is a spacer on the back that rests against the block which keeps them from moving inward and the raised bits on the front contact the timing cover which keeps them from moving outward.
The heads are a set of Profilers that I picked up used and then put all new guts in them. 2.05/1.60 with 195cc runners.
Well after some research and some advice from forum members I am going with a different intake manifold which should be here tomorrow. I spent a little time building the framework for my temporary shelter/paint booth which killed my wrists so I am once again not doing much of anything.
The only option for my heads is the Performer RPM Air Gap which is going to make the air cleaner hit the hood. Lucky for me I was planning on modifying the hood for a stinger scoop so I will simply make the extra clearance for the air cleaner.
Today it is raining but warm enough so I think I will try to climb back into/under the car and see if I can break the body mount bolts free.
I'm going with the RPM Air Gap on my 73 BB as well.
The speed/machine shop helping me out suggested putting a 1/2 to 1 inch thick Phenolic spacer between my intake and carb to act as a heat shield and help prevent vapor lock. He told me they have seen improved low end torque on the dyno when adding the spacers as well.
I am not sure that your 73 hood will not work...I have AFR heads on SBC, with Performer RPM (not Air Gap), and with drop base air cleaner I have plenty of clearance. I believe the Air Gap and Non Air Gap Performer RPM have same height. When you read on Edelbrock website that it will NOT fit a Corvette, you have to remember that later model hoods (73-77) have the raised hood, as opposed to early model hoods....so when Edelbrock says it will not fit it means early model hoods and stock air cleaners. Lots of people on this Forum use the RPM manifolds with no clearance issues.

Another point, not sure what direction you are going, but the picture you have above with manifold on engine has a split bore flange for Quadrajet....and the Edelbrock RPM Air Gap photo has Holley type flange. So make sure you are getting the right manifold for the Carb you are using. My manifold is an Edelbrock RPM (non-Air Gap) for Quadrajet, and it fits fine with drop base. I have factory gasket for Quadrajet (about 1/4 inch thick), but not sure about clearance if you start using large spacers.

I'm planning to use a drop base air cleaner and will only modify the hood if I find it is necessary.
My intention is to not use a drop base air cleaner unless I have no other choice. Having a 3" filter does not help you if you only have 1" of space between the top of the carb and the air cleaner lid...you are still choking down airflow.

Got the billet aluminum timing cover installed after checking clearance on the camshaft thrust bearing (all good!).
You can also see the new Edelbrock RPM Air Gap manifold in place but not bolted down. I am waiting on the correct gasket set for this new manifold (tomorrow).
I also installed my thermostat and water outlet.
Progress continues slowly as my wrists and hands allow...
What was the CID of your engine again...was it a 383...?? I'm curious as to the piston part number and the CC's of the heads, did you calculate the compression ratio??

Reason: add questions
The timing cover and thermostat housing both look like top quality pieces.
I would like to get those ordered up for my motor.
Who is the manufacturer?
Thanks, Greg

I have the same ts housing. Can't remember who makes it. The neck swivels which easily aligns the rad hose. Mine came with an "O" ring seal but leaked. I used a plain cork gasket to fix the leak.
The timing cover also looks like mine which is cast aluminium made by Proform. It fit perfect behind a Stewart Stage 2 water pump.

That is why I passed on the rpm air gap and put on a Team G air gap. My 1-3/4" drop base gives me 3" between the base and lid using a 4" filter. Also, the ports on the Team G were near a perfect match with the AFR 195's.

Is your Team G a single plane or dual plane intake?
