if GM had just made SD4's common engines instead of the iron goose then we'd be able to get em at a reasonable price
but they aren't so we find other options

Nice build-up thread. Can't wait to see it running. As for SD4 power, The drag race car built by the Rod Shop hit 550hp normally aspirated using alcohol fuel. Vanderley Engineering use to build SD4's for the race teams and sell engines for street use. They started at 232hp for fuel injected and emission compliant 2.7L version and a 285hp with a 4-bbl carb non-emission compliant 2.7L (it had a larger cam and higher compression). It was around $10k for the 232hp version and $12K for the 285hp version. Not to mention they would build them to suit. You could get the engines in 2.5L, 2.7L. 3.0L, and 3.3L.

Grrrr....still waiting on the rear seal adapter from KRP. As soon as I get it the short block is going together, and is getting a nice coat of Aluminum POR block enamel.

FINALLY got KRP to start making me a rear seal adapter. $175, but should be done in a couple days. Meanwhile, I've been trying to do some research on the engine managment aspect of my build, investigating options for wideband oxygen sensor/controllers, and ignition control. I would LOVE to have an MSD Digital 7 ignition, but they're a little pricey. I have also started on a prototype (ghetto, IOW) 90* adapter for the manifold to the throttle body. Goes from the squarebore manifold, 90* to the drivers side, with pressure and temp fittings in the middle. I'm going to try to find a nice LS1 TB somewhere, might go junkyard surfing. So far I have alot of pics of parts and what not, but it would be nice to get something put together soon. In any case, one step closer... Nate

What kind of torque can be expected from one of these? I am just curious... I have absolutely no idea about the SD4's capabilities.

The strokers can be VERY torquey motors (NA in the 200-300 range). I hope to hit 400 ft lbs, not sure if that will happen.

Small update. Add another gadget to the list. I'll be getting a DIY wideband O2 unit to make tuning this sucker easier. Should work very well, as the MegaSquirt injection unit has provisions for wideband. Still waiting on the rear seal adapter, though.  I'm about to go crazy waiting on that thing, I don't understand the big delay. Nate

Wooohooo! Rear seal adapter came. Made me feel kinda bad, I had just called the company up and whined about it, about 5 minutes before UPS came. I'll take it in to the shop tomorrow, and have the short block assembled.  Nate
