4-30-20 day for the 430 CanAm aluminum big block Chevy

Joe, thanks for bring this info out. I see around the internet you have been doing that for a while now.

Do you know if any of the alum YENKO crested blocks we siamesed and 4.440 bore? I think they were all standard style wet blocks.

I don't know if the YENKO crested blocks were the CanAm blocks

I have seen a few different Yenko blocks , some have the Yenko crest cast in, some have the letters "YENKO" cast in , some were hand stamped

Draglist Mike Fons
Notes: Won the Popular Hot Rodding meet at Martin, Mich., with a 10.16 to 10.08 holeshot over Dick Oldfield. Ran 10.11 at Edgewater. | Fons had one of the strongest Chevy P/S cars in '70. Few Chevys could keep up with the domination of the Mopar Hemis in the first year of the class. Mike had one of them. At Beeline for the AHRA Winternationals, Mike beat the Camaros of Ray Sullins and Wally Booth in the first two rounds before meeting up with the Mopar of Dick Humbert. A 10.40 dispatched him and moved him into the final against Ronnie Sox. There was really no contest as Sox was about four tenths faster and in the final Fons' 10.54 finished far behind Ronnie's 10.08. Things got a little closer at Pomona for the NHRA Winternationals. There a 10.21 qualified #6 and he was now only two tenths behind Sox who qualified first with a 10.00. He lasted until round two before losing to the eventual winner Bill Jenkins in another Camaro. A week after the Winternationals, OCIR held its Pro Stock Championships. Unfortunately, Fons lost to Sox in the first round. His times continued to drop but so did everyone else’s. At the NHRA Gatornationals, his 10.14 qualified #11 and he improved to 10.09 in the first round but it wasn't enough to beat Don Carlton's 10.08. He was at Rockingham for the AHRA Pro-Am Championships where he beat Eddie Schartman in the first round before losing to Dave Strickler's 10.05 in round two with a 10.31. | Best known NHRA speed 135.33.

Joe, the Yenko blocks to me would either be the crest of the raised letter YENKO. A stamped block I wouldn't trust.

Carleen, Those are about the ET I thought they were running on'70.

Here is some more info and cast #'s too
