What are the thoughts of the amount of hp and compression from this build?
1974 400 block machine shop to .030 over >406
line bored shop balanced on newest machine

crane roller rockers (gold pro race 1.5)
dart shp 202/180 72cc on stock deck height
comtiec gasket compressed 0.30
weiand tunnel ram with twin 4160 450 cfm carbs
holly hp mech fp 110gph
msd plug and play msd wires msd coil
Super Competition, Full-Length, Steel, Ceramic Coated, Chevy Headers
The tiny 450 carbs will not make horsepower power on a tunnel ram.
They are T bucket cruiser-poser carbs.
Get real 650+cfm DP carbs for it.
Edelbrock 750's work well too.
They make engine test dynos to determine HP.
Get some real carbs and dyno it.
The HYD cam will run out of steam and limit power and rpm.
This is a poser girlie-man motor.
