When in Doubt, Adapt
After converting over to our aluminum block 5.3L motor to do the testing, we spoke with the ProCharger people and they told us they are working on a kit that will adapt the power steering mount to an iron LS block that is missing that one essential bolt boss. We came up with what might be a workable solution. In the accompanying photo, arrow 1 points to the one threaded boss that is common between the iron and aluminum blocks. Arrow 2 points to a threaded boss on the aluminum block that is on the iron block but must be drilled and tapped. Arrow 3 points to the boss on the aluminum engines that is missing on the iron block. If we made a 1/2-inch-thick aluminum plate that bolted to an iron block using bolt bosses 1 and 2, we could drill and tap the plate for boss 3 and merely shorten the aluminum spacers by 1/2 inch and mount the adapter to the iron block. That would allow us to use a cheap, iron 5.3L motor with the Procharger blower.

It really doesn't matter what engine you build as long as the mechanic knows what their doing and I think the mechanics at fast are the best. Way to go Travis and the crew!!!

You don't a lot of cubes and the best big block are Fords and ChryCos.I never pit Aerican Muscle over each other anymore.It is Muscle vs imports.

Umm I didn't think the 5.3&4.8 were ls engines. Aren't they Vortec truck engines?

I'd go 4.8L with a turbo, if these guys can tune them and squeeze 6-700hp out of a stock bottom end, cam, and a pair of heads, and get 30mpg. Why would you need anything more on the street? Other than more's never enough:)

LS = easy HP in a compact & lightweight package. No need for a big block anymore unless you really want to run one.

as sweet as the buick 455 is, the block simply cannot sustain much more than 600 horse, not that you need much more than that

Love the mix of new and old. Too bad this one appears to be coil-on-plug powered. Those aluminum heads must be worth their weight in gold!

I don't consider $7,000 a budget build. I could have an inline 6 with more power for the same cash.
