How Do You Think She's Gonna Run?

[Mr. Rustypwnz]

Well, after changing my mind 4 times a day on what engine i should use for my notch (I have 3 engines lol), I have decided upon the navi engine. So here is what it is getting!

Gt500 rods
4.6 compression height pistons
stock cast 8 bolt 5.4 crank.
ported big C heads
some valve springs
stock cams for a couple months
longtubes (modded heavily)
sullivan intake mani with adapter plates (longer runner length)
carbureted, with a couple plate kits later on

So, what do you guys think a 11.85 comp dohc 5.4 would do? Im extremely nervous and excited at the same time. Im hoping to do 350rwhp, I know that sounds low, but we'll see how she does at the track. I should have some pics this weekend.

Have no clue why you wouldn't just taken a used 4v motor and thrown boost at it.

Whats your goal with the car? All motor drag car, Street/Strip, or Street car?

This. Very tame motor easily making 600+

And I pretty seriously doubt it'll make 350 rwhp on stock cams. But I could be wrong.

I'm gonna say it puts down 320-330.

personally for me, I like carb'd/sprayed engines better, and 5.4 4v is uncharted waters for me personally which makes it more fun. I know if I ever wanted more power I can bolt on a turbo and make 1000hp+ and have everyone jerk off to my dyno graphs. lol
