Slant six turbo 500 hp cost analysis
Let the games begin! :happy1:
I am going to simplify this exercise by assuming that the engine in question will be free, since this is simply a comparison to the the other slant six (300 hp) and would cost the same. I was GIVEN my motor, so I know it happens.
I am also going to assume that it is an early slant motor with solid lifters and a forged steel crankshaft.
Since there is basically, only one head available for these motors, the comparison will be easy; the more powerfiul motor will have a full-on, professionally-ported head with larger valves installed (1.74" X 1.5",) while the 300 hp version will get the bigger valves, but no actual porting. beyond a little cleaning up in the valve pocket area.
Let's start with the reciprocating assembly:
Wiseco makes a nice piston (.045"-overbore) for this application. $423.28 This includes a narrow, low-drag ringset which must be filed to your specs before installation. They only fit 198-spec (7.005"-length) rods.
The recommended 198 Rods for this piston are $577.71. It is a forged steel H-beam design and are 7.005"-long.
Bearings: Main and rod kit: $46.99....Summit
Gaskets except for the brass head gasket for the 500 hp motor: $56.00 Summit
Copper Head Gasket for 500 hp motor: $150.00??? Please advise... not sure...
Distributor: Stock slant six electronic...$124.00 for a reman. "Cardone"; Mopar Performance apparently has discontinued it.
That's all for now; beddy-bye time....
More later.
