uh... what? <img src="/forums/images/graemlins/confused.gif" alt="" /> My Isuzu performs quite well, and I started this swap less than a week ago???




I looked at other engines, and actually have a 4.9 caddy motor as well. Diesel? The only diesels that will have the output I want weigh a ton, won't bolt to my tranny (very easily anyways), are over-seas and/or cost way too much.

The 4.9 caddy (200 hp / 300 lb-ft torque) is a cheap motor, has gobs of torque, but is low on hp. I'd probably be quite happy with the torque, but there's not much potential in them without serious work. It would fill the engine bay up for sure, but is short enough to fit without serious problems I think.

LS1 would be an awesome motor, but very expensive and wouldn't bolt to my tranny without adapters. 5.3 vortec same same, except it is cheaper, but also heavier. I also think these motors, short though they are, could cause real problems with fitting their length with the accessory drive on front.

I was looking at a 3400 engine too. Very compact and lightweight, with room I think for twin turbos with it's narrow Vee angle, but I think I'd really be pushing it to get 300 hp out of it.

The 3800sc has good power and torque from the start (240 hp, 280 lb-ft torque), and it has huge potential for upgrades down the road too. Like I said, 300 hp isn't all the expensive or difficult to achieve. If you go nuts, 500 - 600 hp is attainable as well.
