Hi, starting to assemble my block, the specifics are:
408 CI 10.5/1 Compression ratio (calculated)
Balanced Scat cast crank and forged rods and pistons
Edelbrock RPM heads, ported, Manley Race Flo valves with PAC springs
Flat tappet cam/lifters, 1.6 ratio roller tip rockers, cam has over .600 lift
Direct port fuel injection
Block decked, bored/honed, and mains align honed.
Here are the measurements I got for the main clearances, using a .0001 dial bore gauge and then followed up with Plastigauge to double check (pretty accurate BTW)....#1 is at the front
#1 .0025
#2 .0025
#3 .0024
#4 .0030
#5 .0019
A little odd, especially the #4 and 5 being so different....my question is, would you change anything? #5 is pretty thin.... Hi volume or standard oil pump? It is a "Hot" street build....
Thanks...
