303 heads are very simular to the 400s,smaller unmachined chambers,takes a long reach plug and usually have smog ports in the exhaust.The block is way diff on the short deck,has a filled in lifter area like a SBC,has the oil filter diff.The 400 exhaust wont fit on a short deck 303 setup as the pass side will hit the filter.Im sure the 303 version will fit on a 400 setup.Remember there were 2 diff 303 setup,std deck with a long rod and the short deck.The short deck has 2 1/2 mains and was WAY more competetive but because they only made 25 of them,they were not allowed to compete.The std. deck 303 was a dog.Tom

Thanks for the info, hopefully Gary can figure it out from there. He said he would try to get us some pics of the motor for comparison.

I grabbed the Hot Rod at lunch, there is nothing to indicate what they went on. The right side looks like it might clear the A body from but not the left, looks more like F or big car long branch from this pic.

I think they had a proto set for the 366 NASCAR project,might be those as the outlet looks very large compared to my 303s.Tom

Tom Goad is going to be down here next month and I'll just put it on him. I don't know how deep in the RAV program he was, so it's time to find out.

Those are some sweet looking manifolds. Imagine if Chevrolet put a decent set like that on a big block Camaro.

Terry with the RAV Judgement Day passed this along:

Steve,
I really started with a ram air three 428cid with a tri power set-up (I have one photo off that engine) I will send later. Then I went to a 440cid ram air iv and ran that for some years with different carb and cam set-ups from 2 afb's and then to a 1050 dominator. Played with different intakes, gears, and the list goes on. The ram air v was the big project it was a 455 4 bolt main block with 8 sleeves and then bored to 4.250 with a standard 4.21 crank. The block was o-ringed and I had to make my own copper head gaskets, total of 477cid. The roller cam was a Howard with a intake lift of 778, ex. about 740 if I remember right. I also made a special water system for cooling; you can see some of the plumbing in the photos. That was two Gary Williams 1050 pro stock dominators at $1500.00 each on top (and that was back then). Big block Chev push rods, Ridgeway stud girdle. Springs and all that stuff was Comp cams. Rear end was a Chev 12 bolt with a 5.14 gear. The turbo 400 trans. was my own build with a Tci brake and a 5500 stall conv. These are some things just off the top of my head, if you need more just ask. The car ran in Tulsa, Las Vegas Nev., the Texas Motorplex and orange country in California I ran the best ET and mph in Las Vegas at 9.82 148mph. here in Tulsa was a 10.02. I think I still have the et slip for Tulsa. I lost two motors before I got the combo right, the v engine is not like any other Pontiac there is a large load on bearings a other parts because of the large tunnel port heads they flow a lot of air. The valves I used were out of a ford tunnel port they were Manley stainless. The list goes on! The last motor I used was a big block Chev with Pontiac alum. pro stock heads 515cid this motor was only used for testing because I had ordered a dragster and was waiting for it to be finished. I will also send photos of the dragster too. The rods in all Pontiac motors were Bill Miller or Howard alum. rods. Later on I used Childs & Albert. The best time in the dragster was at Mo-Kan 7.82 at 170mph. The ram air v motor were $10.000 each at that time to build. The dragster engine was &18000.00. When I look back I can't believe I did all this, how far do you want to go with this? Terry

I did sell that RA 5 motor with the factory GTO exhaust manifolds a few months ago(wrong block),it brought alot more money than i thought it would,so i did give the guy the factory mag pulse distributor,and the complete mag pulse ignition system. It was a neat piece! I would posta couple of pics if i could figure out how to!!

The manifolds with the heat shields, ok on for the 303 but why the heat shields? Do you suspect they had serious plans of 303 production engine? Wouldn't have been much point in developing heat risers for racing?

Here is what Gary sent:

Here are a few pics of my unrestored "useless" 69 RA5 TA. Sorry the manifold pics don’t turn out very good, but not much room to get the angle on the camera. It might look better if I jacked the car up and took them from underneath it.

You guys are right,no way hot rod manifolds fit gto.I dont know which ones Mullikan had on that Judge,i remember he said he moved the motor over to one side half an inch,and he might have notched the frame .
