They were run in the early 70s,kind of started life as RA Vs but they had no TQ off the corners so they were raced with RA IV heads and a Nash intake.Buck Baker and David Person raced the firebirds in the baby grand series.There are pics of their cars on the net.They used a unique block that was exactly like a RA V but had a drysump provision on the back of the cam tunnel.My block is engineering number one and does not have it.They used a 455 forged pistons with a 7.04 long rod made by MR.Rod Co.The cranks were 3in main forged units done mostly by Kellogs but I know Reath made some for the Bakers.My engine was designed as a IV but I built it as a V.If you go to the Performance Years site there is info on there.Search threads started by Tom S and will be easier to find.Tom
