So Ive put about 30 hours on my new 408sbc... Im not feeling what the builder promised me...
heres the build
400 sbc .40 over = 408
Profiler aluminum 195cc/64cc
nx262 comp cam
RPM performer edel intake
Stock thunderbolt VI
Stock fuel pump
GLM aluminum manifolds with imco stainless risers.
Alpha SS outdrive
Claimed to have 425-475 hp
Timing set at 10* idel and 35* at 4k
4900rpm at 63mph with 23p tempest
So theres the build i have and Im just not feeling the power it should for my Powerplay 185. For this power I should be going 70 easy.... Dont get me wrong there is plenty of crazy torque at 2k-4900k but then it just dies off.
Can anyone point anything out?
