Being a RAIV car...there is no AC box in the way, I'd look carefully at the block casting number on the block flange coming up from the oil filter housing. If the block casting number comes up 9792968 (& its not a 428) or 481708... & it was down to money changing hands with a RAV block being something that was in question, it would be nice to pull the distributor & look & see if the distributor hole is over size like a 455SD. RAV blocks had the oversize distributor hole. Have had several friends with RAV installed engines. Most, just had the factory RAV heads &'intake. Very few guys have gone to the trouble to remachine the distributor hole. BTW, a '70 RAIV distrib is a "2011", only stamped one day, & very hard to find, def worth checking, if getting that far.
Since you indicated no codes or numbers on the block face, will list the folowing 400 casting numbers...
You did look for SR block number stamped furtherdown the pass side block face???
Block casting numbers:
-'70 400 (base 400 & RAIII: 9799914.
(note, a very few late production '70 WS & YZ engines received 9799915 cast blocks.)
-'70 400 RAIV block: 979991(5).
(note: the first 6 digits of an original 9799915 block are cast, the last digit, the 4 was ground off at the engine plant & a specific font 5 was deeply stamped.)
the different casting numbers on '70 400 blocks was for engine plant internal reason to differentiate the 4 bolt main 400 block's bores being machined for slightly looser wall clearance for the RAIV's forged pistons. '70 RAIII blocks, were also factory 4 bolt main fitted blocks with premium Morraine 400 bearings, but used cast pistons.
SR 400 4bolt main blocks cast in July of '70 up into '73, the 481988 casting number was totally wiped off, & 9799915 was stamped in its place. Again specific size & font stamps were used, & there are those in the know that have no problem exposing forgers.
Have personally examined a complete '69 RAV 400 shortblock, but not a '70 RAV fitted block. The latter supposedly has a block casting number of 481708. Would love to have a picture of that block casting number if that's what's in it.
VALUE...looking at the few pics, the paint is burnt off fairly well down to surface rust, & there is rust repairs to perform in major body panels, if it was here, full 1/4s would be replaced with perfect originals, & car would receive a very detailed frameoff. I seriously doubt anyone is going to try & patch the repairs, then repaint, then try & represent as they blended lacquer in the trouble spots. There has been a trend to such silliness. Many times the result is nothing but deception & many collectors have wised up.
Having witnessed what similar condition RAIV Judges bring as projects, 30-50K, is what I'd think that is the ballpark that this one would be in. It going to come down to what parts are missing & if the owner will get off the car. When the body condition on RAIV Judges is extremely nice, & low mile original engine still exists, they bring much much more. This is something that is hard to register with many such owners. They also have no idea the lengths & expense many of us go to restore such cars. It isn't take it down to the corner body shop & have them "restore" it.
Atoll blue is the most common color on a '70 GTO, but it one of the most desirable colors on a '70 RAIV Judge. For several years in the late '80's, I tried to buy an Atoll blue 4 spd RAIV Judge that was in my old home city. Offered very strong money for it, for the time. It had been one of my best friends older brothers from '78-80, & was traded back to the previous owner who then owned it for another 25 years til he died. That particular '70 RAIV Judge has had an SR fitted block & one SR 614 head, since the early 70's, with documentation from the original dealer of the repair. Car was bid on eBay to the mid 40's about 7-8 years ago, then sold off eBay for more. While typical condition driver restored RAIII Judges have taken a beating in the marketplace over the last 2 years, much of that comes as a result from the absolute stupid runup in prices in Value Guides due to the crazy bidding on nearly a dozen '69 RAIII Judges @ Barrett Jackson nearly 3 years ago. Nearly every one of those '69's sold for stupid money, nowhere near real world pricing, & after Value Guides pricing went though the roof, prices fell. Extremely low mile original & cutting edge Concours restored RAIV Judges, typically, are price outliers, & Value Guide pricing, means very little.
Intereting to see what happens with this '70.
