I like this idea..BUT... TPI's are H.P. limited because of runner size among other problems. So if your looking to propell 4000lbs with one it may be disappointing in the end. At best a highly modified 383 block with worked over TPI unit on top might yield just 350-400 horse. And after that you'll find your wallet lightened by a few thousand dollars.Not to mention the extensive prom burning that'll need to be done.
Maybe if H.P. isn't a concern then yes, a TPI engine is probably the least expensive of the late model F.I. engines. You could probably find a 350 TPI from a mid mileage car,complete with tranny,ECM for $800-$1500.Out of the box those produce about 255 H.P., which is nothing to sneeze at but they were in 3400lb cars.
If H.P. is a concern then maybe a better suggestion would be an LT1 from 93-96 or even a newer LS series small block.
You know what would be the cat's a$$... a 2005 or newer 6.0 LS2 out of a wrecked late model GTO! I can see those "GTO" plastic shrouds and everything in your GTO!
.
That might be pricey too though. I do however like this whole idea from a technology and relaibilty standpoint.
