I've also thought it through, there is actually plenty of aftermarket support for these motors. They have a pretty significant stroker kit for them. On the other hand they are pretty low-tech, being a pushrod motor and all. If i was gonna consider a inline 6 truck motor with that big displacement, it would def. be the newer trailblazer motors. 4.0 liters (i think) DOHC. . . and from what I hear a supra 6 speed can be mated to them. there was a recent issue of hot rod mag which had a chevy nomad with one of these bad boys in it. Turbocharged, custom manifolds, 800hp+ easy. Its like a supra motor with an extra liter!!
I was up close and personal with one recently. That thing has 325 or 335 tires on the back of that thing! So perhaps not a foot but about 30-40mm anyways!
the tranny issue would be my main concern. perhaps there is a way to use the AWD tranny and not use the front cv's I've heard of people doing that with the RB26 tranny's.
Bastaad. I agree with most of what your saying. An open mind is a must for this forum. Although i think the original spirit of the site was to improve upon what the z has to offer in stock form. I would consider a l28et pretty close to stock see how little work is involved. And Many V8's have more potential than the L, The RB, 2jz, 7m, etc. etc. etc. Those are all motors that obviously have way more potential than the L28et. I'm just not so sure that the SRT motor has proved its in the same class.
My point simply. The L can make 400hp no problem with no major internal mods. there are only a handful of SRT's making more than 450hp or so. It would be a cool and unique swap no doubt. I've just whooped on way too many srt's to consider that a motor i have to have in my Z. Supras on the other hand . . .

Stage 3 produces anywhere from 310-355 depending on octane.
I am currently running a bone stock 150k+ junkyard NA bottom end(N42) with some bad blowby(rings/lands). the 3.0 is on a stand getting rebuilt. I was on 15psi.
He said he was 19psi, maybe more. I slaughtered him from a dig, which he will not stop whining about. 5 cars from a 25mph roll. Roll races are for wusses. Let just compare dyno charts and save the gas.
I respect the srt4, heck AMS holds the record at 590hp with only an AFC i believe. But if they are ALWAYS gonna complain about their weak platform then screw it. . .
I put the hurt on a Stage 3 Mopar SRT on sat. Bigger turbo, injectors, fuel rail, bigger FMIC, Exhaust, 19psi, etc.
7-10 cars from a dig, and 4-5 cars from a roll.
I'll stick with my l28et! HAHA
