[Herr-Kuhn]

600 HP GM crate engine: $9500
Intake with Fuel Injection: $3500
Renegade Hybrids Conversion Parts: $4500 (best I can tell there is a lot of stuff needed)
Exhaust Headers/Manifolds: $500
Misc Odds and Ends: $2,500 (at least...all the little stuff adds up FAST)

Parts: $19,500, let's say I'm high here and assume it's $18,000 for all the parts assuming you can sell the 32V for $1,500. You've already exceeded the cost of my system by at least $5,000.

Does anybody want to take a guess at the delta on the labor to remove the factory 32V engine, haggle with a bunch of wiring and then re-install an entirely different engine as compared to simply bolting on some parts? My system is like 40-60 hours labor and I can assure you that do do an engine swap like this will be at least 80 hours, if not closer to 120 hours to do it really right.

Then we have the issue of driveability. Radical cam, high compression ratio NA engine with big displacement will be LUCKY to get 12 MPG and have any street manners at all. Boosted 5.0 liter with turbos offline 99% of the time running a much softer CR and still retaining driveability and 20 MPG fuel economy. Power when you need it and economy when your foot is out of it. Plus the turbo engine will have a wider powerband. I looked on Jegs for the price on the 427...because that's the only NA engine making this kind of power. No 350 is going to make these kinds of numbers without some pressure.

+$6000 cost
+50 hours labour
8 MPG less on economy...from now until, well, forever
Resale destroyed...I'm certain this is the case

I think this is a fair assessment of what the possible cost delta is, in fact I'd say I've given the SBC every benefit of the doubt here on cost...the actual numbers probably paint an even further spread on the numbers (i.e. worse than I've presented).

I have yet to see one person give me a straight answer on all the costs on a 600 HP SBC conversion.
