Has anyone stroked their Vortec lately?

450-500 with only heads and intake....hmmmmmm. I have the best intake available for the engine, a much lager throttle body, higher lift/duration cam, headers, exhaust, etc. but the stock 317 heads. I don't believe the stock cam will put out 450-500 hp. I would have to see the dyno test on that. If thats the case, then my 408 would be putting out much more than that. I have to get it on a dyno, but have to find one in Germany. I will dig out my receipts and see what it cost.

sorry i didnt add in that also a decent cam is also required..

there are multiple articles out there for this same exact setup ( Lq4 upgraded with L92 heads, manifold, cam)

the price ranges vary depending on what you replace.. but there are builds for 550 rwhp for about $4.5k

Save some cash for a new HP trans and torque converter about $3000.00 . With the added power the trans will need to be upgraded .

Yes, that's a fact. I spent 3200 on a built tranny and torque converter for that very reason. I am surprised that my factory trans with shift kit is still alive after my initial road test. If anyone is interested, I found CK transmissions in New York has a great deal on built trannys with a one year warranty. He says I cannot break it unless I baja race the rig. I will see what I can do next year. I was looking at the FLT transmissions, but CK was putting in the same parts for a lot less money. I did a lot of checking and they seem to a very reliable business.

I know I could have put out good power on a budget with the 6.0, as they are well built from factory. From a racing family (stock cars, drag cars, 4x4 pullers, boats, on and on) I am one to spend the money on a bulletproof short block, and then you can swap heads, manifolds, cams etc. all you want for more HP. I look at all the bolt on stuff and sound equipment people spend thousands for, and choose to put that into my engine. When I drove my H2 from Oregon to LA to ship it, the stereo was seldom on anyway, cause me and my brother liked the sound of the engine better.....

This is all GREAT information! I'm eager to know what your rig dynos at...

I'm not looking to build the baddest thing on the block...I just wanna feel 'good' when I press that pedal. I don't feel bad now...but I know there's more there. I'd love a Duramax, but I don't want the headache of the whole process. So I'm gonna squeeze my Vortec for a little more umph.

This thread has given me some very valuable info to start educating myself on just how to do that...THANKS!

SIDE NOTE: Where did you get the 408 badge? If I go that route I'm definitely gonna want one of those!

[EuroHummer]

I got the badge from a Ford site of all places. Just googled 408 stroker and the site popped up. Hate to have Ford crap stuck to my truck, but who would know its a Ford item....

If you just want some oomph, you could opt for bolt ons and be done with it. This was a family project, and one of my missions was to get my Dads new shop up and running, which it did. Attracted a lot of attention around the village.

I most likely will not be able to do another build like this, so I decided to do it right. Now my focus is on suspension, making sure its bulletproof for my big trip next year. Dont need a broken tie rod in the mountains of Poland or Romania...
