Brian, The car had a 511 in when I bought it, I changed the heads when I dropped a valve (big over rev) but basically its the same engine god know how many runs it had on it... but I've not even put rings or bearings in it....
I'll try and find another block sometime to build it as a spare.. but as soon as I get my new shop built I'll start building the 540, KB olds block, callies crank, oliver billet rods, 15:1 je and my brodix -3Xtra oval ports... I'll start it on the carb and gas but probably go injected alky sometime... I do have a box of 11.5 :1 coated pistons thatwould be nice to use up if I had a blower, mind you injected nitro sounds good too...
Be lucky with that vette...
