destroked 3.4l "3500"

[Keoki1978]

"IMO i'd just build it with solid parts and not worry about your redline based on stroke.. other factors like port flow and cam profile are going to play a huge factor in how far it'll rev and/or make power. You'll also need to worry about cavitation in the cooling system and weather or not your oil pump can keep up at those RPM's."


Thats just to damn true. I agree with this guy 1000% These cylinder heads, no matter what everyone says about them, are probably the biggest bottle kneck on these engines. As much as we love the 60* for its simplicity and size, the heads will keep your revs down before any stroke or bore formula can predict. I should of said that first, but I like cubes, and even at a 3700, your only at 226CI... I to also like a squared up engine.

Thats all of the stuff I actually have (or have paid for and waiting on delivery) for installation now. I still have a few things left on my shopping list.

im a lil surprised at that turbo i was talking with a vendor for them and they tried getting me to go with a partial sponsorship dam near 50% off the turbo, and was recomended a s3xx . ill have to go check my pms on the other board for the exact model


edit
s366 is what they were telling me to get

LMAO @ the cheetah blood!

The s-256 turbo performs well. Ill simply upgrade the turbine housing A.R. I may bump up to .89 or larger to cope with the increase in RPS.

Bigger turbos are a lot of fun, but Im more interested in a flat, linear power curve. Not merely bulk h.p. This motor is taylored to produce a flat power-curve all the way to red-line.
