XR274HR-10 in 318

I don’t think is a rebuild since the piston in use mentioned above was stock pistons.

If it were a rebuild, I’d use a KB @ 0 deck height for a good ratio and it’s deep valve pockets so I could use a 1.6 ratio rocker and use that Edelbrock port flow to my advantage. A little more top end pop!

Is this a rebuild ?

IF so I wouldn’t be using stock low cr pistons.

For the money it would cost to do the 302 heads probably could with aftermarket.

Since this seems to be mainly a street driving car I’d go a step down in cam eg. 218 @ .050”.500” .
