Alright then! This is my generic response for the e-mails that I get regarding pricing on these swaps:
[FONT="]There's a thousand ways to slice the conversion depending on wants, needs and budget. The fixed (and I use the term 'fixed' loosely as no two projects are exactly the same) costs on these conversions are:
[FONT="]-The parts needed to physically perform the swap, outside of the engine itself. This is everything from the adapter and engine mounts, custom radiator and exhaust, and custom built wiring harnesses all the way down to fuel hose fittings, shifter linkages, mounting brackets and the like. Usually this totals out to right around the $7,000 mark. [/FONT]
[FONT="]-My time. Or any shop performing the conversion, for that matter. I'm typically coming in right around 120 hours on the job, and I get $90/hr, so right at the $10,000 mark. That's assuming the truck is in reasonable condition and doesn't require any special means or extreme effort to tear down due to condition or rust. [/FONT]
[FONT="]-Floor conversion. This isn't always necessary on every swap, but if the truck has an early LT77 or LT85 seat box and transmission tunnel, we'll need to convert to the later style R380 configuration so that the large transmission body doesn't have any clearance issues. All of the NAS trucks are equipped with the R380 floor, while most ROW trucks [FONT="]aren't[/FONT][/FONT][/FONT][FONT="] since the R380 didn't get released until 1994. It usually takes around $1200 in parts to convert, plus whatever coating is required -- be it paint or bedliner.
[FONT="]From there you have your variable cost, which is the engine and transmission. For higher horsepower applications (400hp+) I'm usually coming in around $14,000 for a brand new 6.2 with transmission, while the more modest 5.3 runs around $11,000. If you want a no-hassle powertrain package with a two year GM warranty the crate motors are hard to beat, but on the opposite end of the pricing spectrum I have seen guys picking up complete used 5.3 engine and transmission packages from junkyards in the $3,000 range. If a used engine is in the cards I would expect to budget around $1500 on top of the purchase price just to freshen up things like the coo[FONT="][FONT="]l[/FONT]ing, charging and power steering [/FONT]systems and buy sensors or items that may have been damaged or lost in the mix.
