Your opinion on this BB! Please.
454 block bored over 0.60 to 468 cui.
GM forged rods and Speed Pro pistons.
Ported 990 Bigport heads with SS manley valves 219-188.
Harland-sharp 1.7 ratio rockers. Isky lifters.
Crane roller cam 737-726 314-324 degrees 114 gr lob sep 274-284 @ 0,50
Moroso deeppan and electric waterpump.
Team G intake. Holley dominator 1050.
Compression is 13,2-1.
Is this engine streetable? If not what could be done? Could you reuse the valves and roller gear if you decided to change to alloy heads?
Can you safely bore to 0.60 over?
Thanks

We all have different definitions of "streetable", that has become very obvious. It depends on what your definition is? How do you see yourself using the car? Do you want to try to run on current pump gas? I will say that it has more compression, cam and intake then most here would run on the street.

454 blocks can easily be bored .060 so that is not a problem . 13-1 is a problem and not streetable on pump gas but the heads might be closed chamber so a set of open chamber would help alot as would some of the large 125 cc heads.
The cam definitely is not for the street.
A cam at 254 and 264 @ .050 is pretty wild on the street and vacuum becomes a problem for the brakes and lights.
The domes might also be machined down slightly to lower compression.
