Was the RAV a 400?I'm assuming it is since the RAlV is.

[JLP]

RA-V had a couple of variations, 303 & 400. There were some other cid variations and supposedly had other RA designations. Depends on who at Pontiac (John Sawruk is probably the best) as to whether they were actual designations beyond RA-V. 400 is the most common talked about. The 303 was to be for Firebirds and 400 for GTO's.

I heard of the 400 RAV but not the 303 RAV thats interesting.Why the smaller motor in the firebird?

[gtaa9]

What was the HP difference between the 303 and the 400?

For starters go back and take a look at this thread:

TUNNEL PORT RA V

Thanks for the thread I check it out and found Milt Schornacks website.Interesting site very good information but I never once read about anybody mentioning the size of the RAV.All I saw was 428's and a 421 mentioned never a 400 or 303?I did check out the attachments that were posted and I saw that the RAV's HP was 565 inpressive.

Don't forget about 366.

There are a couple of board members that have RAV stuff and Tom is probably one of the top in the country with effort and rarities.

Though it's not proven on paper, Sixtiesmucle has what I perceive to be one of the most desirable Pontiacs in the country. With an undocumented trip to Pontiac Engineering via Knafel Pontiac, the motor in the Tin Indian may be one of the most exclusive.

Want to really dive of in some controversy go read this thread:

The 303 RA V was developed for SCCA Trans Am series racing. This engines did not perform very well in the series and development stopped. There were some 69 Firebirds running in the series back in day the with 302 Chevys in them. I still wish the 400 RA V's were released in factory cars like Judges and TA's. Nascar tried to use a RA V in 71. David Pearson drove a 71 GTO with a V in it. His team only raced the car for a partial season they could'nt keep the engines together. Ray Nichols engineering built the cars for Pearson, it was campaigned as the number 33 and the number 17 that year. Check out the pics, it's the only GTO that I know of to ever race in Nascar.
