Are they compatable?
I am also building an engine at the moment. Its a 351 cleveland, I have started with a bare block right from scratch. I have an American crank which have more steal in them than the aussie ones, 4v heads and no cam as yet. I am only planning to use this engine as a spare for my ute. When I have finished building it I will put it in my ute and then play with the engine out of my ute. I have yet to decide on a cam I am not an expert on cams and I have conflicting info but I need one that will work down low. Compression will be 9.9:1 780 cfm carby. I wish you could still get the sigerson TQ 20. I had one in a 302 and it was brilliant for my purpose.
