The aluminum block is 303? For some reason I thought it was 400, my memory is floating away!!!

What are these manifolds?

I pulled the alu RA V from the car and replaced it with a complete 303 short deck SCCA motor.The new HPP mag should have a article on it.The Hot Rod mag cover is a complete 400 motor.Notice the oil filter is setup like a long branch motor.The 303 block has the filter screwing into the block from the side.

Yes now I remember you telling me about the swap, my bad.

So are the manifolds on the Hot Rod cover the A body? My copy is at home, so I can't see what it says about them right now.

[tjs44]

not sure if those are A body.There were a few diff designs which are shown in Petes book.A A body set was on a engine sold by John Glasco a few month ago if I recall.As I recall if you parted the engine out the exhaust manifolds sold for the $18000 range.Maybe he can confirm.Tom

There was a local guy here in Tulsa from the 70's and 80's that ran regular in a car called Judgement Day, he was my idol. His name is Terry Drenner and he is going to give me so very cool stuff on his car. I will also have it on our EMPGMC race page ASAP. Here is what I have so far:

And Terry wrote this to me with the first pic:

Gary has a RAV 400 in his 69 Bird and thought the manifolds looked exactly the same as the pic. After you mentioned they were on the 303, he's now wondering what all the differences are. He has 303 heads but not a block and thinks the machined exhaust services look identical to the nekked eye. Are the manifolds the same for 303 and 400 F? Head surface the same? But the filter mounts are different on the block.

Seeing this gets my blood boiling!!! The car ran low 10's, said he got to be good friends with Howards in CA.

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
