4.2L

CJSTME · February 9th, 2008, 08:06 PM

okay, it's time to upgrade options. I want the most power out of my 3.8 going naturally aspirated. I heard a 4.2/4.3 is a great way to add power. What's the highest compression ratio I can do? What if I got a 4.2 from an f150? What year do I get it from? What's the best sounding cam with the most bang for the buck? springs? torque converter? transmission mods to go with it while the engine's out? I could use any help possible.

If you want n/a power:

You want the ssms 4.3L stroker / 4.2L stroker with s3 everything
Or
Rpm's 4.2L stroker with their CNC heads or BV heads

Prob gonna want 4.10gears & detroit tru trac
3500 stall
Jmod

and a dyno tune.

Yep.

Current record n/a is 263hp.

CJSTME · February 9th, 2008, 08:24 PM

how much hp will the 4.2 get me? a lot more than the 3.8? or just 20hp?

ESG-642T · February 9th, 2008, 08:25 PM

Better torque curve.

"no replacement for displacement"

mmvi · February 9th, 2008, 08:41 PM

that's all the 4.2 longblock is good for? i better stick with my 4.6 then.............

El_Cangri · February 9th, 2008, 08:47 PM

I'm going buy v6power.net's numbers not the advertisement numbers on the site.

3500 stall is pushing it alot, hell be good on stock stall on the street maybe 3k if he is gonna race a lot, but 3500 is getting into you need a transbreak area

obdnanr · February 10th, 2008, 02:21 PM

fyi 250 RWHP is on par with the "300 HP" 2005-07 GT mustangs.

w/ the same rwhp as a s197 gt he would put a good 2-3 lengths on him cuz of the weight advantage

HMUSN · February 10th, 2008, 03:58 PM

I disagree.

the TQ of the v8 would even the weight difference out

Avaric3 · February 10th, 2008, 04:03 PM

o tru, completely forgot about the torqueless v6

HMUSN · February 10th, 2008, 04:13 PM

it's not TQ'less.

The V8 just makes more is all.
