TUNNEL PORT RA V

[tjs44]

John,it is interesting over the years how much stuff was written and pics published that were incorrect.For example the pic of the V engine from Bauman(spelling) shows a 400 engine with 303 exhaust manifolds and does not have a V balancer on it.Also there are pics of RA V 400 blocks that are actually 303 blocks.The 303 besides the shorter deck have smaller mains(2 1/2)and is missing the reinforcing rib on the thrust side of the block I believe.It also has a filled in lifter bore area like a SBC.Also the blower block of Arnis that I have personally seen was a 3 1/4 main with splayed caps more like a 455SD than a 400 RA V block.VERY stout piece.Bill Blair has the one I actually saw.Keep up the good work,try and get the Mar 1968 Hot Rod for even MORE great pontiac developmental engines.Tom
